Water Works Secondary Clarifier Rehab Proposal (&) Engineering Services for Secondary Clarifier Rehabilitation TRANSMITTAL LETTER July 16, 2019 Stephen Caswell, P.E., Principal Engineer South Tahoe Public Utility District 1275 Meadow Crest Drive South Lake Tahoe, CA 96150 Subject: Proposal for Engineering Services for Secondary Clarifier Rehabilitation Dear Mr. Stephen Caswell and Distinguished Members of the Selection Committee: Water Works Engineers LLC(Water Works, or WWE) is pleased to submit one (1) electronic copy of our Technical Proposal and one (1) electronic copy of our Cost Proposal for Engineering Services for the Secondary Clarifier Rehabilitation project at the District's Wastewater Treatment Plant. You will find that our team has recent experience with several projects that were very similar to this project that provide valuable insight into our approach. We have proposed a comprehensive,yet direct and efficient scope of work with several optional tasks to ensure that the services provided exactly match the needs of the project. We are excited that the District's Team for the project includes Operations and Maintenance staff and we firmly believe collaboration and garnering input from O&M Staff during project design results in a final product with the highest value to the Owner. You will see that in our proposal, we are not proposing significant field work and testing of the existing clarifier concrete and mechanisms,as we believe this work !7 • was already completed in 2013 as part of the Concrete&Coating Evaluation. We Water Works propose that a thorough 1-day field inspection by our experienced staff we are confident combined with the testing results (core samples, concrete pH testing, etc) from will take care of all of the 2013 Evaluation will provide the information necessary to develop the details • • everything clarifier rehabilitation alternates and final design details. We do not feel that re- it takes to makeour doing this work will provide significant benefit to the project. We understand the projects challenge of maintaining an excellent level of service using limited resources to Corri Zimmerman, PE repair, rehabilitate and replace aging infrastructure that is nearing the end of its P Redding of useful life. Water Works Engineers has prided itself on it's low-overhead structure that allows for us to be nimble, responsive to the needs of our clients, and cost-effective. At the core of our project team, and most critical to any project's success, is the Project Manager. Water Works Engineers' Project Manager Joe Ziemann will not only be providing project leadership and direction, but will also be responsible for technical execution of much of the work.At Water Works,we believe and insist that our Project Managers have an in-depth involvement in the technical execution of projects they manage. This significantly differentiates us from other firms,who see Project Management as a strictly administrative function.Water Works Engineers is a firm that was built from the ground up around experienced staff whose focus is engineering, not marketing, limiting overhead functions to provide our clients with cost effective services. If you have any questions regarding this proposal, please contact Joe Ziemann at: (916) 238-1460; ioez@wwenineers.com Water Works takes no exceptions to the District's Standard Consulting Agreement included in Attachment C of the RFP.

Seville 'ah Lake Cit Mat Based on our experiences, we strongly believe that people execute projects, not firms. The Project will be managed by Joe Ziemann. Joe Los Ang.es and the Water Works Team have a niche skillset of performing many Scuttsdale small to medium sized water/wastewater treatment plant rehabilitation and improvement projects over the past 10-15 years. We understand how important it is to create highly detailed and straight forward construction documents and specifications to obtain good bid pricing on these smaller jobs. We consider this our specialty. As a small firm,our design engineers also commonly perform construction management and inspection on the jobs they design. This provides us with valuable experience when it comes to constructability and common construction challenges, and we apply all of this experience to each new project. WATERWORKS E N G I N E E R 5 Page 12 (W) Engineering Services for SecondaryClarifier Rehabilitation Water Works Engineers has a portfolio of more than 50 wastewater treatment plant design and rehabilitation projects over the last 10 years, and project descriptions for 3 recent projects that specifically involved secondary clarifier rehabilitation are provided below. City of Roseville Dry Creek Wastewater Treatment Plant Secondary Clarifier Rehabilitation Project Project Timeframe: 2011-2014 Construction Cost: $4.0 M Team Members: Client Reference: Bryan Buchanan, Principal Engineer Mike Fisher, Project Manager and Principal in Charge Environmental Utilities-Wastewater Division Joe Ziemann, Project Engineer/Construction Manager 1800 Booth Road, Roseville, CA 95747 Jeremy Kellogg, Structural Engineer (916) 746-1812 bbuchanan@roseville.ca.us WWE provided preliminary design, final design, and construction management services for the rehabilitation of the City's Dry Creek WWTP secondary clarifiers including (4) 85-ft diameter secondary clarifiers, (4) associated RAS Pump Stations, and the plant's Hot Water Loop piping and booster pump. The clarifiers and pump stations were constructed in the 1970's.The existing clarifier mechanisms were painted carbon steel organ pipe type and had corroded to the extent that their structural integrity was threatened. The RAS pumps were over 30 years old and in need of replacement. WWE initially provided a basis of design report (BODR) that analyzed several years worth of mixed liquor and RAS flow data to verify minimum and maximum flows around which the hydraulics of the rehabilitated system would be based, affecting clarifier components such as the energy dissipating inlet(EDI) and the RAS sludge suction system. The BODR also evaluated several options for the new clarifier mechanism design that included: ➢ Clarifier RAS Suction Type: organ pipe (replace in-kind)vs. suction header ➢ EDI Configuration: tangential port, double gate, plate type, LA-EDI ➢ Drive Type: strip liner/ball bearing in oil bath, precision bearing in oil or grease, grease lubricated composite precision bearing ➢ Materials of Construction: long-term net present value comparison of painted carbon steel vs. 304 SST WWE recommended 304 SST suction header mechanisms with grease lubricated composite precision bearing drives (DBS DM075-AE) and worked with the City collaborately to confirm the preferred selections. A seismic analysis of the new clarifier mechanisms was performed. WWE provided final design, bidding assistance (using the City's design-assist model), and construction management and on-site inspection services for the project. } - Existing"Organ Pipe"Secondary Clarifier New Suction Pipe 304SST Mechanism WATERWORKS E N G I N E E R 5 Page 13 (a) Engineering Services for Secondary Clarifier Rehabilitation City of Shasta Lake Water Reclamation Facility(WRF) Improvements Project(Shasta Lake, CA) Project Timeframe: 2016-Present (Ongoing) Construction Cost: $18.0 M Team Members: Client Reference:Jeff Tedder, City Engineer Joe Ziemann, Project Engineer/Construction Manager 4477 Main Street, Shasta Lake, CA 96019 Jeremy Kellogg, Structural Engineer (530) 275-7423 itedder@cityofshastalake.or WWE provided preliminary design, final New Third Secondary Clarifier design, and construction management services for upgrade of the City of Shasta — Lake's 1.3 MGD ADWF plant to meet a new effluent dominated discharge permit with new nutrient and metals limits. The improvements included: retrofit of mechanical bar screens from _ 3 9mm to 3mm, new influent pump station, retrofit of existing oxidation ditch to a screened raw sewage equalization basin for peak wet weather flow attenuation, new 5-stage Bardenpho aeration basin system with E new blowers, rehabilitation of 2 existing secondary clarifiers and construction of a third, retrofit of the travelling bridge filters to cloth disc filters, and installation of a UV disinfection system. Within the preliminary design report,WWE first reviewed the past 3 years worth of plant data to confirm the need for a third secondary clarifier to provide the necessary peak hydraulic and solids loading capacity for the plant with 1 unit out of service. Secondarily, WWE considered the rehabilitation method for the existing two clarifiers, which were approximately 21 years old. A major consideration on this project was availability of funding for initial project construction, as a large majority of the funding was coming from a fixed SRF loan. WWE performed an inspection of the existing clarifiers prior to final design and determined that the existing painted carbon steel mechanisms were in good condition and were ready for another paint cycle, as they had been re-painted approximately 10 years prior. In discussions with operations staff, the remaining life of the drives (mainly the main bearing)was a concern based on previous oil analysis. WWE recommended the following to rehabilitate the clarifiers within the available project budget: ➢ Replace 20+year old strip liner drives with new fabricated steel precision bearing drives ➢ Blast and re-coat existing clarifier mechanism and replace any damaged PVC RAS suction piping ➢ Replace sludge scraper arm squeegees ➢ Replace existing problematic ducking scum troughs with standard scum skimmer and scum beach WWE prepared rehabilitation specifications and drawings,and the clarifiers were cost-effectively rehabilitated for a bid price of just$150,000 each (2017 pricing). WWE designed the new third secondary clarifier as an organ-pipe type to match the existing clarifiers. All three clarifiers ended up with new matching precision bearing drives. WWE is also currently implementing and testing ultra-sonic algae control systems on the clarifiers. WATERWORKS E N G I N E E R 5 Page 14 (W) Engineering Services for SecondaryClarifier Rehabilitation Arizona Public Service (APS) Clarifier Rehabilitation Project(Tonopah,AZ) Project Timeframe: 2017-Present (Ongoing) Construction Cost: $12-15M per Train (6 Trains) Team Members: Client Reference:Jim Sheely, Project Manager Jon Roy, Project Engineer(when at PCL Construction) Water Resources— Palo Verde Generating Station Jeremy Kellogg, Structural Engineer (623) 393-5884 James.SheelyJr@aps.com The Water Resources (WR) at Palo Verde Generating Station (PVGS) consists of seven trains that include Solids Contact Clarifiers (SCC) that provide water softening, as shown below. Each train includes two solids contact clarifiers(SCC)with associated sludge pumps, rake and turbine components,chemical feed systems (CO2, lime and soda ash) and electrical equipment. Six parallel trains consist of first and second-stage clarifiers, solids/liquid separation system, lime system, soda ash system and carbon dioxide system. " Each first and second stage parallel train can treat up to 10,000 gpm. During peak summer demands, the cooling water make-up system requires 60,000 gpm, which necessitates the operation of all six SCC trains. These trains were originally constructed in 1978 and require significant structural and mechanical rehabilitation to allow continued operation over the next 30 years. A seventh train was designed and constructed so that one train can be taken out of service and still meet the 60,000 gpm treatment capacity requirement. Water Works Engineers was retained to assess the current condition of the facilities and develop plans and specifications for the improvements needed for the various systems including Structural, Mechanical, Electrical, and Controls. The improvements include both refurbishment related items as well as design enhancements implemented under the new Train 7 project. WWE is also providing construction management and startup/commissioning services for the project.The improvements are summarized as follows: ➢ Structural - Includes the removal and replacement of deteriorated concrete ➢ Mechanical - Removal and replacement of clarifier drives and sludge pumps, install discharge accumulators on lime slake pumps ➢ Electrical, Instrumentation and Controls—Replace obsolete equipment in - t conformance with current APS standards .0 WATERWORKS E N G I N E E R 5 Page 1 5 (a) Engineering Services for Secondary Clarifier Rehabilitation PROJECT APPROACH Project Understanding The District's wastewater treatment plant has three existing 100' diameter "organ-pipe" RAS suction type secondary clarifiers that were installed in the late 1960's and early 1970's. The clarifier mechanisms are original (approximately 50 years old), and it is unknown exactly when the carbon steel components were last re-coated. The drives are at the end of their industry-standard useful life and a Concrete and Coating Evaluation of the plant conducted in 2013 indicated that the existing carbon steel coatings were deteriorated with rust ensuing on the mechanisms, and that much of the clarifier floor grout was cracked and hollow. The existing clarifiers have several somewhat unusual features, which include: ➢ Elevated RAS discharge piping from suction pipe collection box supported from access walkway. ➢ No scum baffles or scum collection system due to obstruction posed by elevated RAS piping. ➢ The District may operate Clarifiers 1 and 2 in series,with Clarifier 2 as a "polishing" clarifier which should have a much lower RAS rate. Clarifier performance may suffer at times with high SVI mixed liquor. ➢ There is no direct method to measure individual clarifier RAS flow, as all clarifier RAS pipes merge into a common header and may be pumped by one or more RAS pumps. The District has planned for rehabilitation or replacement of all three clarifier mechanisms, including any necessary concrete repairs and replacement of the clarifier floor grout within the Ten-Year Capital Plan. One clarifier is anticipated to be rehabilitated in late Summer 2020, with the other two completed in Summer 2021. Only one clarifier may be rehabilitated at a time to maintain plant capacity and redundancy, and only during low flow periods. The available construction budget in the Ten-Year Capital Plan is approximately $800,000 per clarifier. Replacement of the existing clarifier drives and main bearings is essentially a forgone conclusion given their age and service. Whether the other components (center column, drive cage, rake arms, RAS box, etc.) are recoated or replaced entirely is a question of current equipment condition and project construction budget availability. Unfortunately,the Concrete and Coatings Evaluation Report is 6 years old at this point, and given that the clarifier mechanism coatings were already observed as failing in 2013, additional significant corrosion and deterioration has likely occurred, requiring another thorough evaluation of each mechanism to determine if any significant loss of existing steel has occurred that would preclude simply recoating the equipment. Another challenge to this evaluation is that original shop drawings of the clarifier mechanisms are not available against which to compare current member steel thicknesses to determine if loss or damage has occurred. WWE will perform an alternatives analysis of mechanism recoating/rehabilitation vs. replacement including replacement with painted carbon steel vs. stainless including life-cycle costs and implementation considerations. For other similar comparisons WWE has performed such as for the City of Roseville Dry Creek secondary clarifier rehabilitation project, the long-term life-cycle cost of stainless steel has always been lower, mainly because mechanisms may need repainting as often as every 10 years, and repainting this equipment is very labor intensive given all the structural components, angles, and joints. Based on an initial comparison of the likely construction cost of replacement with new stainless mechanisms based on recent WWE projects and the project budget presented in the Ten-Year Capital Plan, it appears that adequate budget exists for this option. It should be noted that the District recently replaced the primary clarifier mechanisms with stainless steel. In light of this, WWE is proposing an optional detailed existing clarifier mechanism condition assessment task that would include measuring and documenting existing mechanism structural components, assessing their current deterioration, and a more thorough analysis of the scope of work required to adequately rehabilitate the equipment including a seismic analysis of the existing mechanism structure. If this optional task is not selected by the District, a detailed analysis of the structural rehabilitation of the existing clarifier mechanisms will not be performed. WATERWORKS E N G I N E E R 5 Page 16 (W) Engineering Services for SecondaryClarifier Rehabilitation Other aspects of the clarifier mechanism replacement analysis that will be thoroughly evaluated include: ➢ RAS suction configuration options and variations (i.e. standard suction pipe vs. hybrid suction pipe with spiral blade, shown at right) ' _ - ➢ Center feed well configuration -- ➢ Analysis of recent plant flow data and -� hydraulic design requirements ➢ Available drive/main bearing types, recommendations, and O&M requirements ➢ Clarifier wall and launder concrete/coating rehabilitation options ➢ Possible addition of a FRP density current baffle (i.e. Stamford baffle) Hybrid Clarifier with Elevated RAS Pipe ➢ Floor grout replacement considerations ➢ Effluent launder/channel algae control options (ultrasonic, other) ➢ Evaluation of the benefits and risks of potential equipment pre-purchasing ➢ Instrumentation Evaluation: torque control options, possibility of installing mag meters on suspended RAS piping to directly measure RAS flow rate (insertion style vs. inline) Task 1:Data Collection and Review WWE will perform the following sub-tasks to complete data collection and review: 1. Collect and analyze previous 3 years of plant data to include: plant influent flow rate, aeration basin mixed liquor suspended solids and sludge volume index, RAS flow rates. Determine minimum, average dry weather, average annual, average day maximum month, and peak hour wet weather values. 2. Clarifier Field Evaluation: The WWE team will conduct a one-day site visit to inspect and document conditions of each of the three clarifiers once the District has taken each out of service to allow entry. WWE assumes that the District will provide confined space entry support (including observer, access ladders, etc) required for WWE Staff entry. WWE will prepare a safety plan. Inspect concrete and concrete coatings, clarifier anchorage, clarifier mechanism configuration and key dimensions, clarifier mechanism coating condition, identify areas of obvious clarifier mechanism corrosion and section loss. 3. OPTIONAL Detailed Existing Clarifier Condition Assessment: Document in detail clarifier structural components and geometry, measure key component member thicknesses and section loss due to deterioration, perform seismic analysis of clarifier structure (one structure, assume all 3 clarifiers are the same), develop structural improvement recommendations for mechanism rehabilitation alternative. 4. OPTIONAL Site Survey: WWE is including an allowance in the cost proposal to complete site surveying should it be deemed necessary. It is not immediately clear that site surveying is necessary to complete final design as site plans available from previous projects or the 2016 Aerial Site Survey may be adequate for use as a background for a civil/yard piping plan. 5. OPTIONAL Lead Paint Testing: A heavy metals analysis of paint samples collected from each secondary clarifier will be performed to determine the composition of the coating. If the lead content in the paint samples is greater than 600 mg/kg by weight as outlined in California Code of Regulations Title 8 Section WATERWORKS E N G I N E E R 5 Page 17 TX 7 Engineering Services for Secondary ser 1930 Clarifier Rehabilitation urr 1532.1, lead abatement will be required whenever the coating is disturbed. Recommendations for appropriately abating any coatings containing lead including budgetary estimates will be developed. The District does not believe that the clarifier mechanisms are coated with lead-based paint, so if this Optional Task is not selected by the District, WWE shall assume that the existing clarifiers do not contain lead-based paint or other hazardous materials that need to be mitigated during construction and the project bid specifications will also state this assumption. • (3) Clarifier Field Evaluation Site Visits (1 per clarifier) • Clarifier Field Evaluation Documentation Task 2:Design WWE will prepare an alternatives analysis and Preliminary Design Memorandum for the project that will include life-cycle total net-present-worth costs to rehabilitate the existing clarifier mechanisms, replace the mechanisms with painted carbon steel, or replace with stainless steel. In addition, WWE will analyze the new clarifier mechanism design details described in the Project Understanding above, including alternatives for concrete and coatings repairs, and make recommendations based on cost to benefit assessment and available project construction budget. WWE will provide a recommendation of the preferred project alternative including a detailed preliminary design cost estimate, and present the Draft Memorandum to the District in an interactive workshop setting. WWE will receive comments from the District on the Draft Design Memorandum and incorporate the comments into a Final Design Memorandum that will guide execution of Final Design. The Preliminary Design Memorandum will also include a seismic analysis of the ability of the existing clarifier walls, footings, and launders to support a new clarifier mechanism. The analysis will be based on a visual inspection of each clarifier (when out of service) to identify any concrete degradation and the design details shown in the as- built drawings. The oncern with the existing structure is the ability to support the hydrodynamic fluid forces (sloshing) generated in an earthquake, as design standards have changed since original installation of the equipment. In general, the soil for buried water bearing structures is not utilized to resist seismic forces because in order to engage the soil for passive resistance there needs to be a deflection in the walls, and typically that deflection would produce cracking in the walls. The clarifier components also need to be able to support the hydrodynamic fluid forces. Hydrodynamic forces on the components results in an overturning force that is resisted by the center column. WWE will analyze the ability of the existing clarifier footings and walls to support the necessary anchorage requirements for a new mechanism. Water Works does not propose to analyze the existing clarifier mechanism steel structures for compliance with current seismic design requirements, unless the optional sub-task 1.3 described above in Task 1 is selected by the District. This is a relatively labor-intensive task given that the original shop drawings are not available. Also, it is likely the existing mechanisms are not compliant with current standards. Seismic design of new mechanism steel structural components would be part of the equipment supplier's scope of work, while WWE would be responsible for verifying anchorage design and capacity of the existing structure to support the anchorage requirements. WWE will also engage potential equipment suppliers to provide CFD modeling to vet feed well and density current baffle configurations to optimize clarifier performance. WWE has found that working directly with equipment suppliers in this area is most effective. WWE will prepare 90%drawings,specifications,sequence of construction,and cost estimate and present the 90% design package to the District in an interactive workshop setting. The Division 0 and 1 specifications will be South Tahoe PUD standard. WWE anticipates the 90%drawing set to contain the following sheets: WATERWORKS E N G I N E E R 5 Page 18 7H TRFiO Engineering Services for Secondary - °der.1950 Clarifier Rehabilitation ➢ Cover and Index ➢ General Construction Notes ➢ Abbreviations and Legends ➢ Structural Notes ➢ Civil/Yard Piping Plan ➢ Clarifier Structural/Mechanical Plan ➢ Clarifier Structural/Mechanical Sections ➢ Clarifier Structural Details ➢ Clarifier Mechanical Details ➢ Electrical Site Plan ➢ Standard Details The 90% plans and specifications will be essentially biddable with only minor interdisciplinary coordination issues and details to be resolved.

Joe will manage the project and also execute much of it given his recent experience on the City of Roseville and Shasta Lake clarifier rehabilitation projects which are very similar in scope and detail to this project. Joe will provide a majority of the analysis and writing for the Preliminary Design Memorandum and will lead production of the drawings and specifications with support from the Project Team. Jeremy Kellogg—P.E, S.E. Percent Time Available for Secondary Clarifier Rehabilitation Project:25% / All Other Projects: 75% Mr. Kellogg is a Structural Engineer with fourteen years of experience in design and construction. He is well versed in the analysis and design of various structures associated with water and wastewater treatment facilities. His thorough understanding of both static and dynamic loading allows him to develop creative and cost-effective solutions to meet our client's structural engineering needs. Jeremy will perform the field evaluation of the existing clarifier concrete structure and coatings, and verify existing clarifier anchorage. Jeremy will perform a seismic evaluation of the existing clarifier walls,footings, and anchor bolts to determine if any structural modifications or improvements are required to support a new clarifier mechanism. Jeremy is particularly experienced with hydrodynamic loading and sloshing in open tanks, which is a key requirement for analysis of this project. Jon Roy, E.I.T. Staff Engineer Percent Time Available for Secondary Clarifier Rehabilitation Project:40% / All Other Projects: 60% Mr. Roy is a civil engineer with extensive experience in wastewater infrastructure constructability stemming from his work as a Contractor's Project Engineer (formerly with PCL Construction). His expertise includes steel pipe fabrication and construction,yard and process pipe installation,and water and wastewater treatment mechanical systems construction. Jon is an experienced AutoCAD drafter and will be performing both engineering(under the direct supervision of Joe Ziemann) and drafting for the project. At Water Works, we believe that 2D drafting is best done directly by Staff Engineers rather by strictly "CAD Tech" staff. This avoids the process of creating redlines,which are then drafted,and then must be checked by the engineer that created the redlines. This process may be appropriate for large complex mechanical facilities that are drafted in 3D, however we have found that 2D drafting by engineering staff is the most efficient for a project such as this. .0 WATERWORKS E N G I N E E R 5 Page 111 TH TR FiO Engineering Services for Secondary - °der.1950 Clarifier Rehabilitation Tom Frisch, P.E. Electrical Engineer Percent Time Available for Secondary Clarifier Rehabilitation Project: 10% / All Other Projects:90% Water Works Engineers and Frisch Engineering have teamed together on hundreds of projects. Frisch is Water Work's go-to electrical engineering sub-consultant, and we find them to be the most capable in the area. Frisch Engineering will be providing electrical engineering support for the project, which is expected to be fairly limited on this project, however some work involving instrumentation (and power for instrumentation) may be involved. Tom's ability to identify electrical issues and resolve them during design has led to cost savings on many of our projects. He understands the issues that must be keyed in on during the planning phase to ensure the end result is a reliable and operable system. Tom's proactive and detailed approach to design has benefitted many projects. PROJECT SCHEDULE The proposed project schedule is presented below. Water Works recognizes the relatively low amount of float available due to equipment lead time on the first clarifier mechanism and the need to have Clarifier 1 rehabilitated prior to 10/31/20. We will absolutely commit to meeting this important project schedule. The schedule could be improved if the District elects to pre-purchase equipment, but we would like to leave this option open through the design phase.

The sludge collector mechanisms are telescoping gravity suction-pipe sludge removal and center-column feed and peripheral overflow into concrete inboard launders. The "internals" of these clarifiers (center column, energy dissipating inlet (EDI) feed well, sludge suction piping and collection trough, reinforcing truss, scum collection and removal mechanisms, etc.) are in various states of degradation and in need of replacement. A condition assessment was conducted to determine whether or not some components are salvageable, but wholesale replacement of the internals as a package is the most cost-effective approach as it should negate the need to get back into the clarifiers in the near-future and avoid any interferences or dimensional disconnects between old and new components. In addition to replacement of the clarifier internals, the existing inboard launders (including weirs and scum baffles) will be demolished and replaced. The launders are cantilevered 6 feet inboard from the sidewalls, making them difficult to access for maintenance and allowing them to trap floating scum and algae against the clarifier sidewall. Launder covers will be included in the project to inhibit algae growth, but extra care will be taken with the specification of the hatch opening method to insure that maintenance is facilitated rather than complicated. The existing RAS pumps were evaluated to assess their condition and capacity. While their capacity is more than enough to serve the build-out capacity of the 1970's treatment train, the pumps are all over thirty years old, four of them are slightly misaligned (Fairbanks Morse pumps), and all have been rebuilt several times. Based on conversations with plant maintenance staff and what will be significantly lower costs, dry-pit submersible pumps will be used for the replacement. All of the RAS valving and flow meters will be replaced as well, as this equipment is beyond its useful life. The four 85-ft diameter clarifiers have a 12-ft nominal side water depth and mild floor slope (%:12). Two of the existing mechanisms are Walker Process SightWell "riser-pipe" type, and two are Peabody Welles telescoping systems. The City could choose to replace the internals in-kind, with new riser-pipe mechanisms, but riser-pipe type designs have lost ground to suction header designs due to the former causing excessive disturbance of the sludge blanket and the low differential head available to drive solids into the RAS hopper. Hydraulic suction (or manifold type, as they are also called) removal mechanisms will be utilized for the retrofit, because the clarifier floor slope is substantially shallower than that which is typically utilized for scraper type sludge removal (1:12), and City staff is familiar and comfortable with these mechanisms. The existing clarifier drives are cast iron housing, spur gear, "strip-liner" bearing drives that are lubricated with an oil-bath.There are two other designs that should be considered: oil-bath or grease-lubricated fabricated steel precision bearing drives and grease lubricated fabricated steel ultra-high molecular weight composite bearings. These drive types are described herein and a selection will be made for final design with City staff. AoRh W WATERWORKS 2 City of Roseville Dry Creek WWTP Secondary Clarifiers 41A , 41B , 42A , and 42B Rehabilitation Project The energy dissipation inlet (EDI) and feed well design will be based on current understanding of best feed and dissipation approaches in smaller, shallow clarifiers, to allow the City to carry some solids in the clarifiers while avoiding scouring the sludge blanket. The vendors, for the most part, have proprietary EDI and feed well designs that can be modified for the existing clarifier geometry and design loading rates. Minimum dimensions will be included in the clarifier procurement specifications, to prevent vendors from under-designing these items to cut costs, but detailed design of the baffle system can be an iterative process with the selected vendor. There are many vendors in the clarifier component package market, including OVIVO/EIMCO, Siemens/Envirex, WesTech, Envirodyne Systems Inc, ClearStream Environmental and Monroe Environmental. There is no glaring reason that any of these vendors could not provide the system described herein as an equal to another vendor. The sludge volume index (SVI) for the 1970's side of the treatment plant is relatively high, and the short- circuiting in the anoxic zone is likely one of the primary causes. The cost-benefit ratio of density current baffles can be high for relatively small diameter, shallow-depth clarifiers that are loaded with activated sludges having a high SVI. In these cases, turning density currents back into the clarification zone can worsen settling and even lead to an increase in the clarifier effluent total suspended solids (TSS). WWE has developed design criteria (clarifier average and peak hydraulic and solids loading, and structural design criteria) for the project, and evaluated equipment for each of the facilities. The purpose of this Design Definition Report is to convey the design criteria and equipment recommendations to the City for review and comment. Once feedback is received, the Design Definition Report will be renamed the Basis of Design Report and will be updated throughout the project schedule. AORIN (� WATERWORKS 3 City of Roseville Dry Creek WWTP Secondary Clarifiers 41A , 41B , 42A , and 42B Rehabilitation Project CONDITION ASSESSMENT STRUCTURAL ASSESSMENT A structural assessment was made of four clarifiers, 41A, 41B, 42A and 42B. All four clarifiers were in service during the assessment. Due to the clarifiers being in service the assessment was limited to a visual inspection of the exterior above grade concrete and interior RAS pump stations. Structurally, the four clarifiers appear to be in good condition. No evidence of clarifier concrete corrosion, settlement or structural cracking was witnessed. Significant sidewalk settlement was observed around portions of each clarifier most likely due to poor compaction during backfill. The sidewalk settlement is not considered a structural issue but rather a maintenance concern as water will puddle after rainstorms. The initial investigation showed that the four clarifiers are viable for rehabilitation. On May 111h the secondary clarifiers were re-visited because DCWWTP staff were able to take 41A and 41B offline for verification of the condition of the concrete and coating inside the clarifiers. On May 11th the secondary clarifiers were re-visited because DCWWTP staff were able to take 41A and 41B off line for verification of the condition of the concrete and coating inside the clarifiers. The concrete appeared to be in good condition and structurally sound. Minor erosion, loss of cement paste, was observed throughout the concrete walls. This type of minor erosion is common in hydraulic structures that are subject to years of perpetually moving water. Loose cement paste was scraped away to expose sound concrete. The depth of loose cement paste removed was very shallow, approximately 1/16th of an inch or less. The erosion was so minor it does not warrant attention or repair. The upper portions of the wall are coated with what appears to be a chemical resistive concrete coating. The coating appeared to be in good condition and did not show evidence of any bonding failures. Some localized bonding failures were observed between the base grout layer and the concrete slab. A new grout layer will be required to provide a uniform surface preciously conformed to the new clarifier arms. Surface preparation will be required to prepare the existing floor to ensure a proper bond between the existing surface and new grout. During the surface preparation any poorly bonded existing grout will be removed. The anchor bolts used to anchor the center column showed signs of minor surface corrosion. The anchor bolts will most likely be reused to anchor the new center columns. After installing the new center columns the anchor bolts will be cleaned and coated with an epoxy coating to provide lasting corrosion protection. A structural assessment of the three flow split boxes was also performed. The visual inspection was limited to exposed portions of the flow split structures. As with the clarifiers, the three flow split boxes appear to be in good condition and capable of supporting additions to improve flow balance. Further structural assessments should also be made while the flow split boxes are off line to verify the interior concrete and coating condition. (� WATERWORKS 4 City of Roseville Dry Creek WWTP Secondary Clarifiers 41A , 41B , 42A , and 42B Rehabilitation Project MECHANICAL EQUIPMENT CONDITION ASSESSMENT The following existing equipment items were inspected: • RAS Pumps, Piping,Valving and Flow Meters • Secondary Clarifier Internals (includes center column, EDI,feed well, cage, rake arms, riser-pipes and scum removal equipment RAS PUMPS The existing RAS pumps are 38 (Secondary Clarifiers 41A and 4113, Fairbanks Morse) and 31 (Secondary Clarifiers 42A and 4213, Worthington, shown in Figure 1 at right) years old. Operators report that the pumps have been rebuilt/overhauled on multiple occasions, which is difficult on non-clog centrifugals with overhung motors. In addition, the RAS pumps and motors ' for Secondary Clarifiers 41A and 41B are not in very good alignment, leading to noise and vibration. Replacement of these pumps was discussed with DCWWTP staff, and it was agreed that replacement during this project is prudent, as the clarifiers will be offline for several weeks at a time. RAS PIPING, VALVING AND FLOW METERS Figure 1.SC 42A RAS Pump It was agreed that the check and isolation (upstream and downstream) valves and flow meters should be replaced, as they are old and worn and replacement parts are not easiliy obtained. The suction side isolation valves are located underneath the floor slab that the RAS pumps and discharge valving is installed on, making accessing this valve extremely difficult as it is a very cramped and confined space. Operators requested that the new suction side isolation valves be installed with a motor actuator, the controls of which would be located above the slab, so that they would not have to enter a very constricted, confined space to shut the valves to isolate a pump or discharge piping and valving. The decision to replace the discharge side valving and flow meters makes it logical to replace all of the discharge piping, as it will be easier for a contractor to fit the new valving and flow meters, especially with new steel pipe and allowance for some makeup joints. There is also RAS sample piping and a sink in each RAS Pump Station that can be demolished, as operators report this equipment is not utilized. The RAS discharge piping is shown in Figure 3A and 3B.

WWE processed this data, and also used historical engineering reports generated by the City, to develop minimum and maximum flows and loads for the ML and RAS flowstreams.

WWE estimates that with some additional data collection and analysis (specifically for total nitrogen in the raw wastewater) and ancillary system improvements (improved anoxic zone baffling or volume, replacement of surface aerators with fine bubble aeration, etc), the Dry Creek WWTP could someday be re-rated as capable of treating an average day maximum month flow (ADMMF) of approximately 27 mgd. This corresponds to an ADWF treatment capacity of approximately 16 mgd, so this value will be used as the design ADWF for the project, so that the work done does not restrict the DCWWTP to less than 16 mgd ADWF in the future.

Biowin Process Flow Diagram of DCWWTP The RAS flow that would be necessary to support the peak flows associated with an ADWF of 16 mgd would be approximately 9.5 mgd, or approximately 2.4 mgd per RAS pump, assuming even (50-50) flow-splitting between the two sides of the Dry Creek WWTP. This corresponds to 1,650 gpm per RAS pump, which is well within the capacity of the existing RAS pumps (2,100 gpm). This additional capacity is necessary because there are times, even now, where the pumps need to be ramped up to address rising sludge blankets in the clarifiers during wet weather. In summary, the existing design capacity for the RAS pumps is adequate to allow future increases in treatment capacity for the 1970's side of the Dry Creek WWTP. Peak Mixed Liquor design flows were developed based on the future peak instantaneous raw wastewater flows associated with an ADWF of 16.0 mgd, the peak instantaneous RAS rate (rising sludge blanket condition), and an allowance for return flows from the Plant Drain Pump Station (4.8 mgd, according to Initial Assessment (2008)). The peak instantaneous wastewater flow peaking factor used was 2.5, which corresponds to data analysis conducted previously by the City. The resulting peak instantaneous design ML flow of 68.8 mgd was used to evaluate the potential to add the weirs in the Mixed Liquor Splitter Boxes, and to make any adjustments to the Secondary Clarifier weirs, feed well, Energy Dissipating Inlet or Center Column port elevations. (� WATERWORKS 8 City of Roseville Dry Creek WWTP Secondary Clarifiers 41A , 41B , 42A , and 42B Rehabilitation Project HYDRAULIC PROFILE WWE calculated the hydraulic profile through the 1970's side aeration basins and secondary clarifiers, based on the 1981 (Duwante & Stowell), prior to realizing that major yard piping and flow splitting modifications were made to this portion of the WWTP in 1991 (James Montgomery & Assoc). WWE is currently re-calculating the hydraulic profile using the 1991 drawings. The primary purpose of establishing the hydraulic profile is to: 1) set weir, EDI and flocc well elevations in the secondary clarifiers, and 2) determine if there is sufficient hydraulic head available to install new flow splitter boxes upstream of the Secondary Clarifiers to improve what is perceived to be un-balanced hydraulic loading between the four clarifiers. While WWE is gather additional data on the 1991 modifications and finalizing an hydraulic profile for the project, CH21M Hill's (based in part on work done by Carollo Engineers) hydraulic profile, as described in the Initial Assessment (2008), will be used for discussion purposes. It must be noted that this hydraulic profile was based on a peak instantaneous peaking factor of 3.0, which differs from the 2.5 peaking factor that CH2M Hill developed based on data analysis.The 3.0 peaking factor was utilized because CH2M Hill's Hydraulic Profile appears to show a water surface elevation of 136.4 in the 1970's effluent boxes in the Aeration Effluent Flow Split Structure, downstream of a weir that is shown at an elevation of 137.50 ft. WWE will run the hydraulic spreadsheet model to verify that this is accurate, but if it is, then there is approximately 1.1 feet between the weir and the water surface at peak flows. This weir cannot be submerged, as it is critical for splitting flows between the two 1990's and the "two sets of two" 1970's clarifiers, so an allowance of at least three inches should be given beneath the weir. Existing Splitter Boxes The 1970's side of the Dry Creek WWTP has two mixed liquor flow splitting boxes to split flows between Secondary Clarifiers 41A and 41B (Flow Splitter Box No. 1) and Secondary Clarifiers 42A and 42B (Flow Splitter Box No. 2). Flow Splitter Box No. 1 receives mixed liquor flow through a direct 48" ML connection from the Aeration Basin Effluent Flow Split Structure (ABEFSS) that is constructed on the end of the 1990's Aeration Basins. Flow to Splitter Box No. 2 comes through a 48" ML pipe from the AEFSS, but first goes to the old Flow Control Box, then through a 36" ML pipe. Therefore the hydraulics between the two feed systems for the two sets of two clarifiers is uneven, and one would expect to see different water surface elevations in the outlet boxes for 41 and 42 at the AEFS, which is not captured in the CH2M Hill hydraulic profile discussed previously. SECONDARY CLARIFIER DESIGN CRITERIA The Secondary Clarifier design criteria that will be utilized for the design documents are listed in Table 2. The design criteria are based on 1) Flows and Loads analysis, 2) calculations using WWE secondary clarifier design spreadsheets (Appendix A), 3) data gathered from secondary clarifier vendors (Appendix B), and 4) preliminary discussions with City of Roseville WWTP staff.

Allowing a minimum of 3 inches of freeboard downstream of that weir (to insure even flow splitting) means that any new flow splitting structures that are installed upstream of the Secondary Clarifiers must incur new head losses of 5 inches or less. Figure 5 below is a graph of head loss incurred over a sharp-crested weir versus weir length at 8 mgd (slightly less than the peak instantaneous per clarifier Mixed Liquor flow of 8.6 mgd). To incur less than 5 inches of head loss would require a weir length in excess of 20 ft. This is not doable in the space available between Flow Splitter Boxes No. 1 and No. 2 and their respective clarifiers. Rather than construct any means of positively controlling the flow splits between the four clarifiers, WWE instead recommends that the City wait and see if re-setting all of the weir elevations in the four clarifiers helps remedy some of the unequal flow splits that operators have observed. Level sensing could be included in each clarifier, and used to estimate the overflow rate in each clarifier, which could be used with the new flow metering in each of the RAS pump stations to estimate mixed liquor flow into each clarifier. This would not be very accurate, due to inherent inaccuracies in level sensing and flow metering, but it could give a reasonably close estimation of flows (± 5%) between the four clarifiers. Operators could then, in theory, use the existing isolation gates in the Flow Splitter Boxes to induce some head loss into the secondary clarifiers receiving the most flow,to get better balancing at a given flow. If anything is done to improve flow splitting as part of this project, it should be limited to installing baffle walls in the existing Flow Splitter Boxes. (� WATERWORKS E H G I H E E R 5 11 City of Roseville Dry Creek WWTP Secondary Clarifiers 41A , 41B , 42A , and 42B Rehabilitation Project RAS PUMPS Existing Pumps The existing RAS pumps are pedestal mounted centrifugal non-clog sewage pumps with extended vertical shafts to external, roof-mounted motors. This type of pump was chosen because the elevation of the pump head can be flooded, so the motors were mounted on the roof slab of the RAS pump stations. The pumps are all well over 30 years old, and have been rebuilt numerous times. Four of the units (the four Fairbanks Morse pumps, installed in the RAS Pump Stations for Secondary Clarifiers 41A and 41B, do not have proper alignment between the motor and the pump, resulting in wobble and vibration in the system. New RAS Pumps There are essentially two alternatives to replacing these pumps: 1) to replace them in-kind, with similar overhung motors, vertical shafts and pedestal mounted non-clog sewage pumps, or 2) to replace them with submersible close-coupled sewage pumps. The two alternatives are shown in Figure 5 at right (the suction connection will not need an elbow, U-JOINT SHAFTING as the suction piping comes straight up underneath the pumps). 1 Submersible, close-coupled pumps (such as Flygt's N-Series) would cost approximately$28,000 each, whereas Flowserve has quoted eight, in-kind replacement pumps at $55,000 each (See Appendix B for both). Variable frequency drives for each unit will be approximately equal, around $8,000 each. The advantage of submersible, close-coupled sewage pumps is that there is no long vertical coupling between the motor and pump, so there are no potential issues with shaft alignment. Also, pulling an entire unit (motor and pump)for offsite maintenance is generally easier. The vertical shaft on the non-clog centrifugals can be disassembled, and the expected frequency of offsite I maintenance or replacement of these pumps is generally lower than that for submersible, close- coupled units. e However, given the fact that the non-clog centrifugals ----- - - C are nearly double the cost of dry-pit submersibles, it is recommended that the City select these for the replacement. One or more shelf-spares could be included in the project, and operators could relatively _ Figure 4.

This center column will be replaced with a 36" diameter steel pipe (3/8" carbon steel or 304 SST).

The 14" RAS piping is 31 to 38 years old, and there is the potential that the corrugated steel would be crushed further up the pipe than just at the core-drill.Also, as shown in the as-built of the area in Figure 5, there is a joint of unknown material precisely where the contractor would want to core- drill. The disadvantage of the adapter approach is that there will always be an obstruction in the Mixed Liquor flow up through 36" center column (see cut sheet from OVIVO's design below). However, while the Mixed Liquor hydraulics are limited (see Flow Splitting discussion), and utilizing the core-drill method of connecting to the RAS pipe could free up additional hydraulic head between the secondary clarifiers and the aeration basins, WWE does not feel that it is worth the potential risk of damaging the RAS suction piping, because fixing the damage could be difficult and time-consuming. Therefore, WWE will specify that the adapter fitting be provided by the clarifier vendor.

These rely on static head alone to move sludge into multiple sludge removal pipes, where it is conveyed to the end of the pipe in the sludge collection box at the center of the clarifier. The ends of the pipes are fitted with telescoping valves to enable operations staff to modify the head loss through each pipe, and thus modify the sludge removal rate from each individual port and pipe. Sludge exiting each of the riser pipes discharges into the sludge collection well, and is withdrawn through a RAS suction pipe located in the center column of the clarifier. Scraper type sludge removal is not recommended here due to the shallow floor slope of the clarifiers, at %:12. Some vendors argue that a 12:% floor slope does not preclude scraper type sludge removal, but in general scraper type mechanisms on a flat floor does not work well unless sludge blanket levels are kept relatively high, and the shallow sidewall depth (SWD) of the 1970's clarifiers does not facilitate maintenance of high sludge blankets. The City of Roseville operations staff have suction type removal at both Dry Creek and Pleasant Grove, and are very comfortable with the operation and performance of this method. Manifold hydraulic suction is a more effective means of removing sludge hydraulically, and most operators do not utilize the variable sludge withdrawal feature described above anyway. Hydraulic suction sludge removal consists of using one multi-ported pipe on each rake arm, and the sludge is pulled through the ports and into the center collection hopper utilizing differential head induced by operation of the RAS pumps. Having the RAS pumps directly connected to the RAS withdrawal ports can provide more differential head, allowing withdrawal of more dense sludge concentrations than with riser pipe type sludge removal. r.

The most prevalent of the manifold type, in terms of installation numbers, is the Tow-Bro system from Siemens. (formerly Envirex). A cross-section of a typical Tow-Bro suction header is shown below. The suction headers are typically a four-sided trapezoid, oriented as a diamond shaped cross-section with the inlet orifices drilled into the lower side of the leading side of the header, as shown below. There is a "Fluidizing Vane", which is essentially a scoop, directly below the inlet orifices, which fluidizes the thicker sludge on the clarifier floor and directs settled sludge towards the orifices. PEAKED ROOF 5 FLUIDIZING VANE Tow-Bro Unitube Sludge Remover Figure 10.Schematic of Suction Pipe with Fluidizing Vane Though Siemens' Tow-Bro design is very prevalent in the secondary clarifier market, there are numerous other vendors offering manifold hydraulic suction designs, including EIMCO/OVIVO's (01D) design, WesTech's COP"' Suction Header Clarifier (shown below), Clearstream, Envirodyne Systems Inc (ESI), Monroe Environmental and Walker Process. A grout fill will be used along the bottom of the existing clarifiers to provide a precise bottom elevation for the new clarifier mechanism. The existing clarifier bottoms will be high-pressure water blasted to remove any poorly bonded material and provide a clean, rough surface for bonding the new grout fill. WATERWORKS ENGINEERS 18 City of Roseville Dry Creek WWTP Secondary Clarifiers 41A , 41B , 42A , and 42B Rehabilitation Project Clarifier Drives The original secondary clarifier drives on 41A and 41B were Walker Process, 1/2 hp, cast iron, chain driven with secondary worm gear reducer, ball bearing turntable drive with heat-treated alloy steel inserts in annular raceways. The existing clarifier drives on Secondary Clarifiers 41A and 41B are EIMCO oil lubricated strip liner bearings,with a % hp motor(2.8 to 3.0 amps). Secondary Clarifiers 42A and 42B have% hp, 2.2 amp motors. New Drives The secondary clarifier drive mechanisms are turntable drives design for continuous, low torque duty. There are essentially three types of clarifier drives to choose from, based on differences in their main bearing design and lubrication: 1) Worm or spur gear with ball and strip liner bearings running in an oil bath inside a cast iron housing (EIMCO's version of this type is shown at right in Figure 11, 2) Precision contact bearings that can be oil or grease lubricated, in a fabricated carbon steel housing, and 3) grease lubricated precision, sealed ultra high rr- molecular weight (UHMW) composite (Teflon) — bronze laminate bearing in a fabricated steel housing. There have been many studies on the efficacy of oil bath versus grease lubrication of turntable drives. Generally, grease lubrication is preferred for slow moving equipment such as a clarifier drive. However, historically grease has not been thought as appropriate for continuously running turntables, such Figure 11.Clarifier Drive Strip Liner Bearings(EIMCO) as in a clarifier, compared to intermittently operated turntables, such as in a crane, because the grease is continuously displaced form the bearing contact raceway over time, and so has to be re-applied frequently (weekly). Grease can be utilized, but it should be purged/replaced frequently to insure that the contact surfaces remain lubricated. Grease advocates point out that grease inherently acts as a seal against grit and dirt, and does not require weekly or monthly condensate draining as the housings have weep holes, since the grease will not leak out. An oil bath is thought to be more appropriate for continuously running equipment, and is the only option for lubricating the strip liner bearing design, which is by far the most prevalent secondary clarifier drive design. Oil lubrication, if the oil changes are done regularly and properly, provides a better means of insuring that the ball contact areas remain lubricated and of getting dirt and grit out. However, oil lubricated clarifier drives have proven to be high maintenance due to their tendency to leak oil, the need to frequently remove condensate WATERWORKS ENGINEERS 1n 7 City of Roseville Dry Creek WWTP Secondary Clarifiers 41A , 41B , 42A , and 42B Rehabilitation Project from the drive, and the difficulty in changing the oil. In general vendors recommend changing the oil every six months, although some installations utilize a yearly oil change. In dusty environments thoroughly clearing the old dirty oil has proven problematic. Some agencies, including the City of Roseville, have tried pressurized air blowouts on either side of a diesel flush - between oil draining and re-filling, to limited effect. There are oil-lubricated precision bearing drive designs available, including one of the WesTech drives, the DBS D Series drive, and the HerculesTm drive that is provided by Envirodyne. Because of the difficulties with condensation, seal leakage and drive oil changes; and despite the frequent grease cycles, grease lubricated clarifier drives have made inroads into the secondary clarifier market. WesTech markets a precision four-point bearing drive that can be grease or oil lubricated, shown in the graphic below. This drive bearing is similar in design to the HerculesT`" drive that is provided by Envirodyne, and to the D Series drives by DBS Manufacturing. BM 70 The City of Woodland WWTP has both strip-liner bearings and WesTech's grease lubricated precision bearings operating on primary and secondary clarifiers. Plant maintenance staff report much higher satisfaction with the grease-lubrication requirements than with the oil - changes. There is a second grease-lubricated precision bearing alternative available, which is a sealed ultra-high molecular weight composite liner (bronze-teflon laminate) bearing from DBS Manufacturing (DM Series). DBS advises that this bearing only requires grease applications every five years, and is resilient to condensation within since the Figure 12. Cutaway of Precision Bearing Drive UHMW composite can use water as a lubricant as well as grease. These drives come with a 10-year standard warranty and are being sole-sourced for a secondary clarifier rehabilitation project at the Sacramento County Regional Sanitation District's WWTP this year. WATERWORKS E N G I N E E R 5 20 City of Roseville Dry Creek WWTP Secondary Clarifiers 41A , 41B , 42A , and 42B Rehabilitation Project It must be noted that the track record for both strip liner bearings and precision bearings (grease or oil- lubricated) is very good in the wastewater industry, as long as they are properly maintained, including adherence to 1) recommended draining of condensate, 2) recommended oil changes or grease purging and injection and 3) in the case of strip liner bearings, regular inspection and replacement of strip liners. The track record for the UMHW composite grease lubricated bearing drive is not very long, but the standard warranty of 10 years compensates for the shorter track record. Therefore, the decision between clarifier drive mechanism designs should be made based on maintenance. Maintenance staff generally seem to prefer the regular (weekly or monthly, depending on the gear or bearing) grease application to six month oil changes. One clarifier vendor, ClearStream Environmental, uses only DBS Manufacturing drives, and provided an adder for their budgetary proposal for upgrade from DBS' strip liner bearing drive (D30-AE) to the UMHW composite bearing drive (DM075-AE) of $14,000. Across four drives this comes to a $3,500 price difference between the two drive types. An argument could be made that this increase is worth the 10-year warranty alone. Sole- sourcing this drive will not limit the number of responding vendors, as most if not all of the vendors have utilized a DBS drive to meet a specification at one time or another. WWE recommends that the clarifier drives be driven with variable speed drives. It is understood that the City has rarely if ever altered the speed of the existing riser-pipe mechanisms. However, having the ability to easily adjust the rotational speed of a suction pipe mechanism is more important, as these mechanisms typically include only one rake arm, and the lower profile of the mechanism does not stir up the sludge blanket as much as the much taller profile of a riser-pipe type mechanism. Other options that are available for the clarifier drives,that the City should consider including: • Reversing rotation—to back the suction pipe off an obstruction • Torque limit switch, or in some cases, a 4-20 mA torque transmitter • Loss motion switch—to detect when a mechanism has failed • Oil level switch—where oil bath lubrication is utilized The drive size will be adequate to provide the torque requirements listed in Table 1: 18,000 ft-lb in operation and 36,000 ft-lb stalled torque. This will require a minimum 42 inch diameter turntable drive with a minimum 0.50 hp motor. (� WATERWORKS E H G I H E E R 5 21 City of Roseville Dry Creek WWTP Secondary Clarifiers 41A , 41B , 42A , and 42B Rehabilitation Project Energy Dissipating Inlet Design Alternatives The critical design parameters for the EDI are its geometry and total volume and its energy dissipating methodology. The purpose of the EDI is to facilitate re-flocculation of the mixed liquor by increasing particle collisions, dissipate energy in the inflowing mixed liquor (and specifically reduce vertical currents), and minimize disturbances in the sludge blanket. The standard design approach is to provide an EDI diameter between 10 and 13% of the secondary clarifier diameter (85 ft), which results in a diameter between 8.5 and 11 ft. A 10 ft diameter EDI will therefore be specified. The top of the EDI extends above the water surface by six inches. The bottom of the EDI is sealed to within an inch of the center column. Flow exits the EDI via openings spaced equidistant around the perimeter. These ports will extend a minimum of three inches above the water surface to allow scum and other floatables to be discharged. Secondary clarifier vendors have different detailed approaches to design of the Energy Dissipating Inlet (EDI), also referred to as the flocculation well. Generally these can be categorized as: • Tangential Port—also referred to as "scoop" outlet design.These have been shown to impart a rotational flow within the feed well at high flows, and will only be allowed if baffles are provided on the inside edge of the flocwell that slow this rotation. • Double Gate Surface Ports—these have adjustable gates on the outlets, but operators do not regularly utilize the gates in most cases. • Plate Type—this is a proprietary EDI design by Siemens. • LA-EDI Ports—this is a proprietary design that is commonly used due to its proven performance at peak flows. It has opposing ports placed underneath the EDI, using the exit velocities from the ports to slow the opposing port velocity. Examples of these four categories of EDIs are shown in Figure 13, below. Any of these designs can be made to work well with a given clarifier geometry. The approach that will be taken with the EDI specification section will be performance based, but will have a minimum diameter 10 ft (or 8.8 ft square for the square-shaped plate- type designs), a minimum height of 3.5 ft (depth of 3 ft below the water surface, extend 6 inches above the water surface), have ports that extend a minimum of 3 inches above the average water surface elevation and that are sized to provide a maximum discharge velocity of 1.5 ft/sec at peak flow, and a minimum discharge velocity of 0.5 ft/sec at minimum flow.

The scum beach will have a scum trough that extends the full length of the scum beach. The scum trough will be flushed using a dual flush system incorporating both a mechanical flush valve that is actuated as the scum arm passes over the scum beach, and a solenoid actuated flush connection on the facility's plant water system. The scum trough will include a six inch discharge connection for flushing scum into the six inch scum line that conveys the scum and flush water to the Plant Drain Pump Station. Alternatively, the City could opt for a "full-radius" scum baffle and scum trough, that would extend through the feed well to the EDI wall.This is done in some installations where there are relatively high amounts of scum. WATERWORKS E N G I N E E R 5 23 City of Roseville Dry Creek WWTP Secondary Clarifiers 41A , 41B , 42A , and 42B Rehabilitation Project ACCESS BRIDGE, WALKWAY AND PLATFORM The existing access walkways and platforms are coated carbon steel. Consideration was given to salvaging these by removing them from the site and having them blasted and re-coated offsite. This is not recommended, for three primary reasons: 1) unless the original coatings have been removed and replaced since the late 1970's and early 1980's, it is likely that the coating contains lead, 2) the existing secondary clarifiers have two different platform designs: Secondary Clarifiers 41A and 41B have only a walkway, with no access platform like that on Secondary Clarifiers 42A and 42B (see photos of both installations, below; and 3) the modification work that would be required to make the walkways (and platforms)work with new center columns and drive mechanisms. Ri r01 Figure 14.Two Access Walkway/Platform Types at DCWWTP A quote for offsite blasting and re-coating was obtained from Stockton Tri Industries (STI), which was recommended by City of Roseville treatment plant staff. The quote was contingent upon the existing coatings being lead-free, and all brackets and hardware removed prior to receipt of the walkways by STI. STI quoted $8,400 for each walkway/platform (Appendix B), and it is estimated that removal, delivery, pickup and re- installation would cost an additional $5,000 to $10,000 per unit (depending on the level of rework required to fit the platforms around the new drives on clarifiers 42A and 4213).Therefore, the average cost for refurbishment of the walkways/platforms is approximately $15,000 each, assuming no lead-based coatings. The new access walkways and platforms (all secondary clarifiers would have platforms around the new drives) are estimated to cost approximately $30,000 each, so there is some potential savings in refurbishing the existing units. However, the contractor will likely receive some scrap value for the steel and aluminum, and the new walkways/platforms will have more room around the new drives and will be provided by the secondary clarifier equipment package vendor, minimizing contractor coordination work for mounting the walkway and platform to the center column. Materials Selection There are three basic approaches to materials selection for clarifier "wetted metals", or internals: 1) coated carbon steel, 2) 304 stainless steel, and 3) galvanized steel. Coated carbon steel is by far the most common material utilized. However, 304 stainless steel is utilized by some agencies due to the high cost of coating the clarifier's wetted components (center column, center cage, EDI, flocculation/feed well, and sludge removal WATERWORKS ENGINEERS 24 City of Roseville Dry Creek WWTP Secondary Clarifiers 41A , 41B , 42A , and 42B Rehabilitation Project mechanism), and the higher cost of sand blasting and re-coating these components, which some agencies report having to do every 10 years or less. Galvanized steel has been used in several installations, but on at least one occasion a failure of the zinc coating has been observed. Galvanized components are not recommended for the DCWWTP. WWE prepared a net present value (NPV) analysis comparing using coated carbon steel versus 304 stainless steel. Budgetary cost proposals for both materials were solicited from two secondary clarifier component vendors (Siemens/Envirex and ClearStream Environmental, both are included in Appendix A).The budgetary cost proposals are summarized in Table 5 below. Because certain components included in Siemens/Envirex proposal would not meet WWE's final recommendations for design, a 10% contingency was added to their pricing. In addition, WWE has current pricing on first coating and blasting and re-coating of secondary clarifier mechanisms for the City of Redding's 80-ft diameter secondary clarifiers at the Stillwater WWTP. These were added to the budgetary cost proposals for carbon steel components. Table 5.Secondary Clarifier Component Costs(Coated Carbon Steel vs. 304 SST) Proposal Budgetary Cost First Coating Cost Total First Cost Siemens/Envirex Carbon Steel $528,000 $45,000 per Clarifier, $708,000 $180,000 total Siemens/Envirex 304 SST $913,000 $0 $913,000 ClearStream Environmental Carbon $627,000 $45,000 per Clarifier, $807,000 Steel $180,000 total ClearStream Environmental 304 SST $869,000 $0 $869,000 The cost to blast and re-coat two secondary clarifiers at the Stillwater WWTP was approximately $75,000, on average from six contractor bids.The cost will decrease as more clarifiers are included in the scope of work, so a cost of $65,000 was used for the NPV analysis. The coating life was assumed to be 10 years, which was supported by experiences at the City of Woodland, and by the condition of the mechanisms at the Stillwater WWTP, which had not been re-coated since installation approximately 20 years ago. There is significant corrosion in the existing clarifier mechanisms. In addition to the 10-yr re-coating cost, DCWWTP maintenance staff pointed out that there are annual inspection and touch-up costs that should be captured. For that, $5,000 annually was applied to the carbon steel, and $2,000 was utilized for 304 SST(to capture inspection cost). A discount rate of 6%was utilized, and both 20-yr and 30-yr NPV periods were calculated. The results are shown in Table 6 below. Table 6.

The existing precast concrete launders are currently supported by cast-in-place concrete support brackets. The existing concrete support brackets will be modified to support the new inboard launders. The extent of the support bracket modifications will be dictated by the dimensions of the launders. A portion of the top face of the support brackets will be demolished to provide room and support the new launders. Each support bracket currently projects 9 feet into the clarifier. This support length will be greatly reduced by relocating the new launders to the clarifier perimeter. The additional length of the support brackets will be demolished where no longer structurally required. Exposed/cut rebar within the support brackets will be burned back and coated with epoxy to protect from future corrosion. The new inboard launder will have a single sided v-notch weir, and will utilize the existing clarifier sidewall face as the outside face of the new launder. A new cast-in-place bottom and vertical inside launder wall will be constructed and tied-in and sealed with the existing sidewall utilizing epoxy dowels. The existing concrete at the construction joint interface will be roughened and coated with an epoxy bonding agent to help bond the new launder bottom to the existing clarifier concrete wall. The bottom of the cast-in-place concrete launder can be constructed at the same elevation around the perimeter and grout filled along the bottom to provide a slope, or the slope can be formed into the cast-in-place launder. The preferred method of construction to achieve a slope within the bottom of the launder is to utilize a grout fill so that the modifications to the existing support brackets can be consistent throughout the clarifier and the launder inside vertical face can be a constant height Launder Covers Launder covers will be provided, consisting of molded fiberglass panels that are attached together to form a continuous cover over the launder trough, weir and scum baffle (See Figure 15).The Cover shall be designed and manufactured to inhibit incident sunlight from striking the surfaces of the launder and weir. Individual sections will be a minimum of four feet in length and curved to follow the curvature of the tank.The covers will be designed to open away from the operator and toward the center of the tank.The hinged Cover Section will extend outward toward the tank wall and swing open to allow inspection and maintenance of the launder and weir. In the closed position,the Cover Section rests on an FRP support flange attached to the inner wall of the tank. Handles or lift rings may also be required for some panels. A means of limiting the travel of the hinged Cover section, in the form of a restraint cable or tether, may also be provided to protect against damage.

Preliminary Launder Cover Design WATERWORKS E N G I N E E R S 28 City of Roseville Dry Creek WWTP Secondary Clarifiers 41A , 41B , 42A , and 42B Rehabilitation Project tm ELECTRICAL AND INSTRUMENTATION AND CONTROLS DESIGN DEFINITION The motor control center and VFDs for the RAS pumps and clarifiers will be replaced with a single motor control center located in the existing electrical building. It will be connected to the 800A buss located on the East wall of the building. The existing PLC will be reconnected to the 1/0 from the new clarifier drives and RAS Pumps. It will have its programming modified for the revised 1/0 connections. The clarifier controls will consist of a full speed motor starter with HOA switch, torque warning, torque alarm shutdown, lock-out-stop, and status monitoring and control for the SCADA system. The reset button for the torque alarms will be located on the MCC cubicle door and in the center of the clarifier. A local disconnect will be provided at the drive mechanism. The scum trough shall be automated with a flushing system. If the system senses the clarifier rake through the position switch,the flushing solenoid valve shall energize and flush the scum trough for a set delay period. The RAS pump controls will consist of a VFD with HOA switch, speed control, lock out stop, run light, and alarm light. The VFD will be connected to the existing PLC using Ethernet Modbus TCP for control and monitoring. Independent VFDs and controls will be provided for each RAS pump. The electrical panelboards and transformers in the RAS pump vaults will be replaced along with the lights, fans, switches, receptacles, and sump pump. The RAS flowmeters will be replaced with 10-inch mag meters. The remaining instrumentation in the RAS Pump Stations will be replaced such as vault flood switch and thermostat. Field conduits will be re-used where possible. New wire will be required for all power and instrumentation. New conduit will be required on the clarifiers and in the RAS pump vaults. The preliminary one line diagram and P&IDs for the RAS Pump Station and the four Secondary Clarifiers are provided in Appendix C. = WATERWORKS E H G I H E E R 5 29 City of Roseville Dry Creek WWTP Secondary Clarifiers 41A , 41B , 42A , and 42B Rehabilitation Project tM 30% DESIGN COST ESTIMATE An Engineer's Estimate of Probable Construction Cost (EOPCC) was developed for the complete project as described herein: - Replacement of Secondary Clarifier internals with 304 SST wetted components - Replacement of launders, launder cover system,weirs and scum baffles - Replace RAS Pump Stations, including pumps (including electrical gear), piping, valves,flow meters, lighting and panels - Replacement of existing Secondary Clarifier isolation sluice gates The cost estimates can be found in entirety in Appendix D. The cost estimate utilizes an average labor rate of $60/hr, which reflects conservative prevailing wage rates. A 10% design contingency is included, which is lower than typical for a 30% design estimate, but is appropriate for this project where the scope of work is well understood. Contractor overhead was set at 12%, and contractor profit was set at 8%. A 10% construction contingency is included to account for unforeseen conditions at the site, and to provide the City with additional budget for minor additions to the scope that would be initiated via owner requested construction change order. Finally,the contracted fee for WWE ($297,300)was included to obtain a total project cost. The EOPCC for this project is $ 3.84 million (M). The City originally had a targeted budget for this project of$3.0 million. In order to bring the construction cost to within this target, the Project Team elected to develop a "base bid" project that would include only those project components viewed as absolutely essential, but then include the additional work and materials upgrades that the City would like to include if the budget permits as bid alternates.The project can then be advertised for contractor proposals, and the Project Team can do some value engineering with the selected contractor to develop the final construction scope. WWE has developed a preliminary base bid with bid alternates described in Table 7, below. Table 7. Engineer's Opinion of Probable Construction Cost Project Total EOPCC Base Bid: Includes replacement of Secondary Clarifier internals with coated carbon steel wetted components, replacement of launders, launder cover system, weirs and $2.62 M scum baffles Project Bid Alternate EOPCC (Adder to Base Bid) Bid Alternate "A": Replace RAS Pump Stations, including pumps (including electrical gear), piping, $0.85 M valves,flow meters, lighting and panels Bid Alternate "B": Replacement of existing Secondary Clarifier isolation sluice gates $0.15 M Bid Alternate "C": Secondary Clarifier internals with 304 SST wetted components $0.20 M (� WATERWORKS E H G I H E E R 5 30 CITY OF ROSEVILLE DRY CREEK WASTEWATER TREATMENT PLANT SECONDARY CLARIFIER REHABILITATION PROJECT MAIN ST 1� r 00 0 VINEYARD RD DOUGLAS BLVD AREA OF 80 WORK A ' _ PROJECT T , .••.� 'x LOCATION 311116, -

Senior Engineer Project Manager y y Education Experience Registration Memberships 4 B.S.—Civil/Environmental Eng. 22 years Registered Civil Engineer AWWA CA State Polytechnic University, California - C67194 CWEA San Luis Obispo Credentials: California Water Environment Association SSO-WDR subject matter expert • CWEA Board of Directors, Director at Large (North) • Author - CVCWA/BACWA SSO Response BMP Manual • Guest Lecturer—CSU SAC& Cal-Poly SLO on Trenchless Technologies • Certified NASSCO Pipeline and Manhole Assessment Trainer • Certified NASTT Pipe Bursting and CIPP Design Best Practices Mr. Fisher has over 22 years of experience in managing all phases of planning, design, and construction management for new and existing wet utility infrastructure. He has extensive experience in hydraulic analysis and condition/capacity assessments in preparation of rehabilitation and replacement recommendations for wet utility infrastructure. He is experienced in trenchless construction methods and is certified in pipe-bursting and cured- in-place pipe (CIPP) best design and construction practices by the North American Society for Trenchless Technologies (NASTT). Mr. Fisher specializes in management of complex projects requiring coordination of multi- discipline design teams. His "hands-on" approach to design, attention to details, and exceptional communication skills are what make his projects successful. Mike led the development of Water Works"risk"based infrastructure failure analysis protocol and has utilized that protocol in the preparation of prioritized, time-phased, capital improvement plans for numerous existing water and sewer systems. Representative Project Experience Wastewater Treatment Infrastructure City of Roseville Dry Creek WWTP Digester 1&2 Structural Assessment Project- Roseville, CA—Mr. Fisher is the Project Manager overseeing condition assessment of Digester 1 and 2 at the City of Roseville Dry Creek WWTP. During routine maintenance and cleaning, Mr. Fisher and the Water Works inspection team provided a thorough structural assessment of the concrete structures, in particular the flat top and domed roofs and interior mechanical piping, to assess its condition and identify more significant rehabilitation and/or replacement needs. Mike worked with the Contractor responsible for the routine cleaning project to remove all fluid and materials in the digesters;wash and clean all internal components; and pump the tank dry.They then set-up a scaffolding and lighting system for use by Water Works for the structural assessment. Water Works team efficiently completed a visual assessment and took concrete core samples for material testing to characterize the condition of the digester and summarized the findings and recommended improvements in a structural assessment report. City of Roseville Dry Creek Secondary Clarifier Replacement Project- Roseville, CA— Mr. Fisher was the Project Manager overseeing the complete rehabilitation and replacement of four circular secondary clarifiers. Project included demolition of all existing internal mechanical equipment; re-tasking of existing concrete structures and supports; drive mechanism and replacement of all clarifier mechanical equipment with all stainless steel; RAS pumps and controls. City of Roseville Dry Creek Wastewater Treatment Plant pH Control Feasibility Study—Roseville,CA—As Senior Engineer, Mr. Fisher performed preliminary engineering analysis and design report identifying chemical injection and operational strategies to positively control pH downstream of cooling towers, which are required for control temperature of effluent at sensitive waterway discharge. 0WATERWORKS 1 E N G I N E E R S MIKE FISHER, P.E. City of Roseville Pleasant Grove Wastewater Treatment Plant Aerated Grit Chamber Rehabilitation— Roseville, CA—Mr. Fisher was Project Manager on the design of rehabilitation for concrete deteriorated by Microbiologically Induced Corrosion on the influent channel walls, aerated grit chamber and grit chamber effluent channel. Project includes 12 MGD by-pass pumping system; removal of existing liner and surface preparation; concrete rehabilitation with hydraulic fast-setting cement motor; and construction oversight and testing of Aero-Lock Liner installation. Sewer Lift Station Rehabilitation and Replacement Ross Valley Sanitation District Pump Stations 12 &13 Rehabilitation Project— Greenbrae, CA— Mr. Fisher was the Senior Engineer for the alternatives assessment, preferred rehabilitation method selection, and preliminary engineering analysis for 5-pump / 10 MGD Bon Air (PS12) and Duplex/0.5 MGD Greenbrae (PS13) Wastewater Pump Stations. Alternatives analysis included review, combining and update to the District's SewerCAD and InfoSWIMM hydraulic models to determine the required PWWF capacity for each. This analysis resulted in identification and confirmation that a gravity pipeline connecting PS12 to PS13 would allow for decommissioning of PS12. The gravity pipeline required construction through a congested economically vital commercial area, so a trenchless microtunnel alternative was evaluated. Subsequent to selection of the preferred alternative, Mr. Fisher served as the QA/QC Manager for the 2,100-LF pipeline and complete rehabilitation of PS12, including reconfiguration of wet-pit to self-cleaning wet-well and replacement of the five water cooled shaft driven pumps with three VFD dry-pit submersible pumps. STEGE Sanitary District, Burlingame Sewer Pump Station Rehabilitation — El Cerrito, CA — Mr. Fisher was the Project Manager overseeing the detailed design, and bid/construction phase services for a duplex 5-HP 300 GPM submersible pump station rehabilitation. The Project re-tasked the existing wet-pit and dry-pit to serve as a pseudo self-cleaning pump station along with upgraded valving and emergency by-pass pumping quick connect improvements. Electrical controls included pump power inverter and control logic that "learns" from actual system operational flows and adjusts pump speed to increase pump operational efficiency resulting in over 20% energy savings compared to standard on/off control. Water Treatment/Pumping/Storage/Distribution San Jose Water Company Cambrian Pump Station Replacement—San Jose CA—Mr. Fisher provided QA/QC on the design and permitting of a new CMU block pump station with two 100 hp pumps and two 200 hp pumps, two 1000-gallon bladder tanks, new MCC, and associated valves and piping. Demolition of the existing pump station and other facilities on site were completed to create room for the new facilities. Hazardous materials on site were sampled for and mitigated.A historical report was created to ensure the new facilities did not impact the remaining historical facilities on site. San Jose Water Company Belgatos Reservoirs Replacement—San Jose CA—Mr. Fisher was the Project Manager for the preliminary design, final design, permitting, and construction management for replacement of San Jose Water Company's (SJWC) Belgatos Reservoir.
