Team members: Rob Natoli, Craig Olson, Arashdeep Singh, Brien Clark, and Greg Mieczkowski 04 South Tahoe Public Utility District I Section 03 1 Firm's Approach to Project 01 03 Firm's Approach to Project HDR's approach to manging your project is presented in this section. A detailed scope of work can be found in our Cost Proposal (separate document). Figure 3-1 on the following page provides HDR's design approach flow chart for the project. We pride ourselves on being responsive to our clients' requirements and meeting or exceeding expectations. Our budget and schedule controls, coupled with project management, coordination, and communication skills of our team members, will provide high -quality products and outstanding service to the District. Project Management Approach HDR's project manager, Rob Natoli, has more than 14 years of experience in water and wastewater engineering. Rob led the design of two District rehabilitation improvement projects to implement mechanical and concrete condition assessment findings to the District's aeration basins and primary clarifiers. Through this work, Rob has laid a firm foundation of effective communication and trust with your staff and acquired knowledge of your procedures and standards. Rob believes that communication is the key to a successful project and will schedule a weekly call with District staff to discuss project progress and issues. A kick-off meeting, preliminary design report review meeting, and 90% design review meeting will be held with the District and HDR staff, with agendas and minutes prepared by HDR. Rob will prepare weekly status reports, which will include task -by -task information on work completed, estimated percent completed, outstanding issues, and budget and schedule status summaries. Invoices will be prepared monthly, with the latest status report attached. Responsiveness to Client's Needs HDR has a history of effective and efficient project management, including dependability, timeliness, and submission of progress reports. As demonstrated on our past projects with the District, we are committed to being responsive to your needs. Our project management approach is built on trust, a clear definition of shared goals, and a mutual understanding of the necessary steps to achieve those goals. We have assembled a team that is custom -fit to your project. Our team is bound together by a commitment to be a true partner to you on this project and beyond. Trust is achieved through transparency and effective communication. We foster this through partnering meetings, task force meetings, weekly project team coordination meetings, and a number of electronic communication tools. Our communication tools integrate scope -of -work activities with schedule, resources, and budget details. These tools give our project management team a vivid picture of accomplishments, work in progress, milestones, and future activities, and allows them to quickly and easily communicate them with you. They also allow our team to identify variances and plan corrective actions to maintain schedule and budget targets. Additionally, the tools produce status reports and other documentation that are used to analyze and present the project status to you in concise, understandable summaries. 05 South Tahoe Public Utility District I Section 03 1 Firm's Approach to Project 01 HDR wastewater treatment plant condition assessment data will be field verified to determine if conditions have changed since the 2013 field work. z Seismic analysis for new mechanisms will be discussed at the kickoff meeting. Structural/seismic analysis to confirm that the existing concrete basin can support new mechanism reactions (including seismic loadings). s A detailed design memorandum that provides design criteria, plans, and section layouts and key project issues will allow the completion of a 90% set of drawings and specs that are essentially complete. This approach will improve project efficiency and reduce the design schedule. 06 South Tahoe Public Utility District I Section 03 1 Firm's Approach to Project 01 Our project management approach is reinforced through proven accountability measures, which can include co -location and design task forces to meet commitments and emphasize shared goals. Everything we do will be a coordinated effort on behalf of you to achieve our shared objectives. Three control processes are vital to good project management: quality assurance/quality control (QA/QC), budget control, and schedule control. We have documented these processes and train our project managers in control systems, procedures, and methods. Budget and Schedule Control We have a consistent history of meeting schedules and budgets while maintaining technical excellence. Our project managers are equipped with a variety of tools to develop, track, and maintain budgets and schedules. Company policies are designed to assist project managers in the timely completion of projects within budget. For a project to be considered a success, work must be completed on schedule, within budget, and error free. At the start of each project, our project manager prepares a Project Management Plan (PMP) to document all information necessary to execute a successful project. The PMP is an internal document that serves as a road map for the project team. The PMP defines project resources and includes client contact information, project description, scope of work, deliverables, budget, administration procedures, and filing requirements. It also covers communication methods, such as use of an e-Room, intranet sites, electronic documentation, written documentation, and methods of handling media requests for information. The PMP also includes a project -specific Quality Management Plan, which helps maintain high levels of quality in our work efforts. We use a combination of company -developed tools and procedures for delivering quality and consistency in our work, managing internal tasks, maintaining communication, and staying ahead of schedule and under budget. We are always willing to incorporate new methods, as our clients and project work dictates. Budget Development, Tracking, and Maintenance At the onset of the project, we prepare budgets that include prorated billing rates to accommodate merit increases for staff. Initial budgets and scopes of work are developed, reviewed by senior staff familiar with the work being performed, and approved by an authorized officer of the company, who enforces strict criteria for pricing projects based on past experience (e.g., labor cost per drawing sheet, minimum hours for preparing specifications). When we are selected for a project, budget information is entered into our web -based accounting system that is linked to the timesheet database. This system is available to the project manager for tracking time spent on projects. Each month, the project manager receives a project summary report from the accounting department that shows the total cost incurred on the project for the month and to date. We maintain close control over project costs by means of detailed initial cost projections, appropriate 07 South Tahoe Public Utility District I Section 03 1 Firm's Approach to Project 01 personnel allocations, accurate scheduling, periodic project reviews, and close communication among project participants. Our department manager performs a project review with the project manager at least twice during the duration of the project to make sure the project is progressing as promised to the client. Project Schedule Development, Tracking, and Maintenance At the onset of each project, we will develop a project schedule using milestones identified in the scope of work and via your input. The individuals identified on the project team are entered into HDR's computerized work planning system, which provides on-line information about staff availability for the dates identified in the project schedule. If a team member is shown to be over -utilized and unavailable to work on a project, then the project manager will, with the City's approval, evaluate and reassign (or add) resources to make sure the schedule is met. Weekly work planning meetings allow project managers to address scheduling conflicts if they arise. Resources are allocated as necessary to provide conformance to the project schedule. If needed, additional resources can be drawn from nearly 10,000 staff in over 225 computer-linked offices nationwide. Adjustments to Budget and/or Schedule During the course of the project, situations can arise that can impact the project budget and/or schedule. When this happens, HDR first prepares a proposal for additional scope and budget for approval by the Project Management Plan (PMP) Quality Management Plan (QMP) Project Planning Review Risk Assessment client. Once a signed approval is received, HDR pulls in any additional resources needed to complete the additional work. The project schedule is updated to show revised milestones and timelines, and workplan information is updated online. If necessary, personnel assignments are adjusted to meet the revised schedule. HDR's QA/QC Program We maintain a fully documented QC procedures manual. It includes forms and checklists used by the project managers and QC persons assigned to every project. Every report, document, and plan is checked for accuracy and verified that it meets the client's terms. Each checkpoint on the form has a notation that the document was checked and that it complies with the client's desires, as well as a plan of action if it does not meet QC standards. QC procedures and standards assure that every deliverable is checked for accuracy before it reaches the client. Our goal is to set the industry benchmark for excellence in services we provide to our clients. We accomplish this through work well done, staying true to purpose, and exercising discipline. It is our policy to consistently provide professional services that satisfy statutory and regulatory requirements and that meet or exceed your expectations. To achieve quality in our work, we have developed a Quality Management System (QMS) based on the fundamental principles and guidelines set forth by the ISO 9001:2008 series of international standards for quality management.

Solids separation for the secondary treatment process is accomplished via five secondary clarifiers, four of which are square ("squircular-type") 75-feet-long each, constructed in 1976. Per City staff, the square clarifiers have only received routine maintenance since construction. The preliminary life -cycle assessment performed by City staff of the four square secondary clarifiers determined that the clarifiers were in a varied state of deterioration based on normal wear and tear. A schedule was established and funds were budgeted to rehabilitate these clarifiers. This will extend their useful life to maintain normal plant operations. The City also wishes to replace the Return Activated Sludge (RAS) pump discharge valves and the secondary clarifier influent gates. These mechanical elements are in poor condition and have reached the end of their useful life. The City's goal is to start the construction of the necessary improvements to in the first or second quarter of 2015. Project Objectives This project includes the following objectives: O To conduct and document a condition assessment of the four square secondary clarifiers, using Secondary Clarifier No. 2 as a surrogate for the condition of all secondary clarifiers. O To provide and evaluate alternatives to rehabilitate and improve maintainability of the square clarifiers to achieve optimal long-term performance. O To recommend replacement of the discharge valves of the six RAS pumps and the sluice gates that feed Secondary Clarifiers No. 1 through 4. Project Tasks and Deliverables To accomplish the project objectives, the project was organized into the following specific tasks: 1 Order No. R2-2013-0006 /NPDES No. CA0037541 issued by the San Francisco Bay Regional Water Quality Control Board, adopted on March 13, 2013.

Secondary Clarifier No. 2 was taken out of service and inspected completely. It is assumed that the findings within the basin of this clarifier are also representative of Secondary Clarifiers No. 1, 3, and 4, which were not drained to be inspected. The field investigations were conducted on April 1 and 2, 2014, and included observations and testing of different components that make up the clarifier basin, sludge removal mechanism, and ancillary facilities for Secondary Clarifier No. 2. Specifically, the following observations and evaluations were conducted: O Visual observations and photo documentation to determine and record the condition of the coating, metallic components, and concrete on accessible areas of the interior surfaces. O Structural evaluation and compliance with current codes. O Degree of rusting on metallic components. O Concrete evaluation O Non-destructive testing methods (e.g., Schmidt Hammer Test) used in the field to verify compressive strength of the concrete.

City of San Mateo 3 Secondary Clarifier Rehabilitation Alternatives Analysis Summary Report August 8, 2014 C:\pwworking\sac\d0591687\028-228748-Secondary Clarifier_2_Final Report.docx Final Summary Report: Secondary Clarifiers Rehabilitation Alternatives Analysis SECONDARY CLARIFIERS CONDITION ASSESSMENT (TM No. 3 Summary) Condition Assessment Methodology Visual Inspections Inspections and testing were performed from inside the secondary clarifier and from the walkways above. The concrete was visually inspected for signs of acid attack, mechanical abrasion, cracking, spalling, staining, or other forms of damage. The steel was examined for signs of corrosion and metal loss. Details on the procedures followed are described below. Evaluation of Concrete in Service Evaluation of the visual condition of the concrete was performed in accordance with American Concrete Institute Publication ACI 201.1R-08, "Guide for Conducting a Visual Inspection of Concrete in Service. " Aural Testing (Sounding) Aural testing was performed on the concrete structure to determine the location of voids and delamination. Testing was performed by tapping the concrete with a ball -peen hammer in multiple locations across its surface. The pitch and character of the resulting sound indicated whether the concrete was sound or was delaminated from the reinforcement or substrate. Concrete pH Testing Phenolphthalein solution was used to test the pH of the concrete structure to determine the extent of carbonation. Phenolphthalein is a pH indicator that appears colorless below pH 8 and bright fuchsia or purple at pH greater than 10. Sound concrete has a pH of 12 or higher. At locations inside the secondary clarifier where the coating had failed, a small amount of concrete was chipped away and the newly exposed surface was sprayed with phenolphthalein solution. This process was repeated until a color change was observed. The approximate depth of carbonation was measured. Concrete Hardness Testing The concrete hardness was tested in situ using a Proceq Type L Schmidt Hammer. The Schmidt Hammer is a nondestructive testing device that uses a steel rod to impact the concrete surface with a known force and measures the rebound distance. The rebound value is correlated with the concrete compressive strength. Three locations on each wall of the secondary clarifier were tested to characterize the concrete in the submerged zone, and two locations on the inner side of each walkway were tested for comparison. At each test location, 8-10 Schmidt hammer readings were taken in accordance with the manufacturer's recommended testing protocol. Trial readings were taken on the grout floor slab; however, these readings were inconclusive.

Areas of coating loss were documented and photographed. The type of coating defect encountered (cracking, peeling, bubbling, etc.) was also recorded. Degree of Rusting Evaluation of the corrosion on steel members was performed in accordance with ASTM standard D610, "Standard Method for Evaluating Degree of Rusting on Painted Steel Surfaces. " Visual evidence of corrosion was noted and photographed. Ultrasonic Thickness (UT) Measurement Steel member thickness on the rake arm structure was measured using a Panametrics ultrasonic thickness gage. To measure the thickness of a clarifier component, a small area of bare steel on the component was located and cleaned with a wire brush and towel. A small amount of ultrasonic couplant was applied to the steel, and the UT probe was placed flat on the surface. The thickness was measured at 3 to 6 locations for each part. Condition Assessment Summary Concrete Structure The cracking and delamination of the grout slab on the clarifier floor may be of concern in the future. If deterioration of the grout continues, the material may begin to break up and spall, leaving an uneven surface at the bottom of the clarifier. The structural concrete of the clarifier walls appears to be in good condition, with relatively few cracks and no significant spalling or degradation below the water line. The coating on the concrete walls is failing. Minor cracks in the east, west, and south walls allow slow seepage from the other tanks. The clarifier launder trough on the west side has a minor crack at its bottom. There are several spalled areas on the walkway concrete; the reinforcing steel in these areas appears to be very close to the surface (less than one inch of cover). The most severe spalling is in the center of the north side, at the location of the bridge. There is also some transverse cracking of the walkway slab in this area. The remainder of the walkway concrete appears to be sound; it is free of significant cracking, spalling, staining, or efflorescence. Steel Draft Tube Arms The steel arm that supports the draft tubes assembly has coating loss in several areas; however, the exposed metal appears to be adequately protected by the existing anodes. Minor corrosion is occurring at the anode attachment points in the heat -affected zone around the welds. Some of the jumper cables intended to provide current to metal fittings on the sludge takeup pipelines are broken. A jumper cable on the corner arm is also broken.

The center cage structure is mostly intact up to the water line; the top angle plates are actively corroding. The scum baffle has corrosion and metal loss at the water line. Corrosion on the scum baffle plates may be a result of galvanic action between the carbon steel plates and stainless steel bolts. The scum removal platform has locations of active corrosion and metal loss. Pipes and Supports The large, nonmetallic pipe penetration on the south wall of the clarifier appears to be in good condition, as do its stainless steel supports. Some of the nuts and washers at the ends of the U supports are corroding. The 6" scum pipeline at the north end of the clarifier is heavily corroded. Pipe fittings and supports are likewise actively corroding. This pipeline may fail in the near future. Walkways and Guardrails The steel bridges show significant corrosion (pitting and general metal loss) on the east side. Section loss has occurred at the connection between the bridge beam and the electric drive motor assembly. SECONDARY CLARIFIERS STRUCTURAL EVALUATION (TM No. 2 Summary) Structural Assessments A structural/seismic evaluation of the existing concrete clarifier structure was performed based on the basis of structural analysis and design information in the original 1976 drawings and the field investigations conducted in April 2014. The interior and exterior walls of the clarifiers were checked for the appropriate hydrostatic and hydrodynamic forces of the fluid, soil pressures and surcharge loads. The Design Capacity Ratio (DCR) was calculated for the structural elements. If the DCR ratio is greater than 1.0, then the member is overstressed. Members are acceptable if the DCR ratio is equal or less than 1.0. Our analysis indicates that the clarifier meets the requirements in the ACI standards. Based on field measurements, the 1.5-inch diameter guardrail posts on the clarifier concrete walkway and bridge deck are on a maximum spacing of 5.7 ft and 6.8 ft, respectively. The walkway guardrails are embedded into the concrete but the embedment depth is not known. The bridge guardrails are bolted to the bridge steel beams. Per requirements of the CBC2, the guardrail system was evaluated for a lineal load of 50 pounds per linear foot applied at any point on the top rail or a concentrated load of 200 pound applied in any direction, and to transfer this load through the supports to the structure. Our calculations show that both the walkway and bridge guardrail posts are overstressed. The DCR ratios for the walkway and bridge guardrail posts are 1.98 and 1.48, respectively. Also, during our field condition assessment, it was observed that the concrete around several of the walkway guardrails is cracked and/or spalled. This 2 CBC: California Building Code 2013 City of San Mateo 6 Secondary Clarifier Rehabilitation Alternatives Analysis Summary Report August 8, 2014 C:\pwworking\sac\d0591687\028-228748-Secondary Clarifier_2_Final Report.docx Final Summary Report: Secondary Clarifiers Rehabilitation Alternatives Analysis condition weakens the connection of the guardrail to the concrete walkway. In addition, some of the toe plate fasteners show signs of ongoing corrosion. The steel bridge decks are constructed with '/4 in checkered plate, supported on the sides by two 10-in deep wide flange beams. TM No. 1 identifies that the east bridge beam shows corrosion (pitting and general metal loss) at mid -span of the beam and at the connection of the beam to center column support. Also, the connection of the beam to the center column support is made with only a single steel bolt with marginal edge distance (see Figure 1-A11 in Technical Memorandum No. 1). Our evaluation indicates that the bridge structure, including the corroded steel beam, meets the requirements of the CBC code. Potential Structural Modifications The project team reviewed two potential basin geometry modifications for the secondary clarifiers: O Circular Geometry: This involves modifying the squircular basins to generate a basin with a circular bottom with circular top. New launders would be required. Two concepts were studied for the circular geometry as depicted below: Plan section Concept A (Concrete RIIl �: Plan Section Concept B (WalIsand Slabs) The first concept involves filling the rounded corners with solid lightweight concrete to the top of the clarifiers. This concept increases the total weight of the clarifiers by 18%. The second concept considers hollow rounded corners with 14-inch concrete walls and 10-inch top slabs. The weight of the clarifiers will not be increased as part of this option. O Filleted Geometry: This involves modifying the squircular basins to generate a basin with a circular bottom and retaining the square top of the basin. Existing launders would be used. The filleted geometry is depicted below: Section Our structural analyses indicate that neither the circular geometry nor the filleted geometry modifications, using lightweight concrete fill, will significantly increase the demand on the existing foundation system. However, it is preferable to consider concepts that do not substantially increase the load on the existing City of San Mateo % Secondary Clarifier Rehabilitation Alternatives Analysis Summary Report August 8, 2014 C:\pwworking\sac\d0591687\028-228748-Secondary Clarifier-2—Final Report.docx Final Summary Report: Secondary Clarifiers Rehabilitation Alternatives Analysis foundation system. Thus, if the circular geometry is selected, Concept B, involving the construction of this modification with walls and slabs is preferred. Evaluation of the Clarifier Center Column Support System A structural evaluation of the clarifier center column support system was performed to determine whether the existing concrete clarifier structure is adequate to support the new sludge removal mechanism. The assessment was based on preliminary drawing and load information for the C1earStream mechanism system. The clarifier center column, a freestanding structure, is connected at the base to an 8-foot thick concrete pile cap which is supported on six concrete piles (see Figure 2-2). Our evaluation indicates that existing concrete clarifier structure, including the pile cap and piles, is adequate to support the C1earStream mechanism loads but the existing concrete at the base will need to be locally modified to receive the new mechanism anchor bolt system, specifically in the drain box area. This concrete modification will be determined in the final design after the mechanism system has been selected. Summary and Recommendations Based on our structural evaluation and the condition assessment, we recommend the following: 1. The walkway and bridge guardrails do not meet the CBC code and should be replaced with new CBC-compliant guardrails. The clarifier walkway guardrail posts can be side mounted with stainless steel bolts adhesive anchors to the concrete clarifier. The bridge guardrail posts can be bolted to the existing bridge steel beams. 2. Damaged concrete on the walkway can be repaired with SikaTop 111 Plus as manufactured by Sika or similar. 3. The corroded guardrail toe plate fasteners should be replaced with new fasteners. 4. The corroded bridge beam could be replaced or repaired with new reinforcing steel plates and the beam connection The center column support should strengthen with a two -bolt or welded connection. 5. Any of the proposed basin geometries are structurally viable options, as they do not increase the load on the existing foundation system beyond its capacity. Selection of basin geometry should be based on operational and economical considerations. 6. The existing concrete clarifier structure, including the pile cap and piles, is adequate to support a new mechanism loads but the existing concrete at the base will need to be locally modified to receive the new mechanism anchor bolt system, specifically in the drain box area. SECONDARY CLARIFIERS REHABILITATION ALTERNATIVES ANALYSIS (TM No. 3 Summary) Identification of Alternatives for Secondary Clarifiers Rehabilitation The two alternatives considered to perform the rehabilitation of Secondary Clarifiers No 1 through 4 are: City of San Mateo 8 Secondary Clarifier Rehabilitation Alternatives Analysis Summary Report August 8, 2014 C:\pwworking\sac\d0591687\028-228748-Secondary Clarifier_2_Final Report.docx Final Summary Report: Secondary Clarifiers Rehabilitation Alternatives Analysis Alternative A: This alternative includes the replacement or refurbishment of the secondary clarifiers' structural and mechanical components based on the condition assessments provided in previous TMs3.

Description of Secondary Clarifier Basin Geometry A description of three potential basin geometries were analyzed in this project, including their comparative advantages and disadvantages, is presented in Table 4.

Comparison of Potential Geometries for Secondary Clarifier Basins Squircular Plan Circular Plan Filleted J L Section Section Section • It allows maintaining all available surface area, which helps to maintain current capacity of the clarifiers. • It does not require building additional structures and takes advantage of the existing effluent launders. • Eliminates the need for corner sweeps to remove sludge from the corner of the basin. • The radial symmetry provides a more homogeneous residence time and effluent quality in all sections of the clarifier. Maintains available surface area, which maximizes surface overflow rates. Eliminates the need for corner sweeps to remove sludge from the corner of the basin. Allows the use of the existing launders. Description of Sludge Removal Mechanisms • Requires corner sweeps to remove sludge from the corners of the basin. • The lack of radial symmetry does not provide ideal residence time and effluent quality in all sections of the clarifier. • Reduces available surface area by approximately 18 percent, which reduces clarifier capacity. • Require building additional structures (walls and slabs), including new effluent launders. • The lack of radial symmetry does not provide ideal residence time and effluent quality in all sections of the clarifier. • Requires filling the corners of the clarifiers to create a circular footprint at the bottom of the basin. • Sludge Scouring may occur near the corner of the launders (this can be mitigated by blocking the corners but will diminish launder capacity). • Very low side water depth at the corner of the clarifiers. • Loss of volume and side water depth will cause a loss of capacity. The three mechanism evaluated in this project where draft tubes, suction header, and spiral blade mechanisms. Brief descriptions of these mechanisms are provided below. A comparison of the advantages and disadvantages of these mechanisms is presented in Table 3.5 in TM No. 3. City of San Mateo 11 Secondary Clarifier Rehabilitation Alternatives Analysis Summary Report August 8, 2014 C:\pwworking\sac\d0591687\028-228748-Secondary Clarifier-2—Final Report.docx Final Summary Report: Secondary Clarifiers Rehabilitation Alternatives Analysis Draft Tubes Mechanism The Draft Tubes (a.k.a. Organ Pipe) Mechanism is the mechanism type currently installed in Secondary Clarifiers No. 1 through 4. This type of mechanism utilizes the differential head pressure between the liquid level of the clarifier and the liquid level in the sludge collection box to remove sludge from the clarifier. Sludge flows through vertical and horizontal legs of pipes into valved openings in a central sludge box, where it reaches a free surface condition, and then out of the clarifier through a return activated sludge (RAS) pipe that is inside and concentric with the center column. There are two flow control points — the sludge valves and the RAS pump. Suction Header Mechanism The Suction Header (a.k.a. Plenum Suction) Mechanism uses orifices in a tapered header that sweeps the bottom of the clarifier to remove the sludge from the clarifier. The sludge then flows to a center, submerged manifold and out of the clarifier through an embedded RAS pipe. Plow blades on the opposite arm move heavy solids to a separate hopper at the tank center. Spiral Blade Mechanism The Spiral Blade (a.k.a. Spiral Scraper) Mechanism employs rotating spiral blades to move sludge along the sloped tank floor. The continuous, tapered blade moves sludge to the center of the tank for withdrawal. Sludge then flows within the drum to the withdrawal point on the center of the tank floor, where it is removed from the clarifier. Corner Sweep Mechanism If the City chooses to keep the existing squircular geometry for the secondary clarifier basins, the mechanisms described above will have to be fitted with a rotating corner sweep at each arm of the mechanism. A typical corner sweep mechanism, similar to ones currently installed in the WWTP, include a vertical steel plate blade with reinforcement supported by steel pantograph arms. The pantograph arms will operate parallel to each other to maintain an approximate 45 degree attack angle. The corner sweep rake blade will sweep the entire flat tank section in each corner of the tank. The rake blades and pantograph arms will be kept in constant contact with the tank wall by a pivoting counterweight assembly. Rehabilitation Alternative Analysis Summary and Recommendations Clarifier Basin Geometry As described in the previous sections, the basin geometries considered for the rehabilitation of the squircular secondary clarifiers were squircular, circular, and filleted. The main advantage of retaining the squircular basin geometry is that it keeps intact the existing clarifier capacity based on surface loading rates (SLR) considerations and it is also the most economical alternative. Because this is the existing geometry, not only is the cheapest way to rehabilitate these clarifier, it is also likely that rehabilitation based on this geometry can be implemented in the shortest construction timeframe, which is something attractive to City staff as this will reduce the clarifier downtime. City of San Mateo 12 Secondary Clarifier Rehabilitation Alternatives Analysis Summary Report August 8, 2014 C:\pwworking\sac\d0591687\028-228748-Secondary Clarifier_2_Final Report.docx Final Summary Report: Secondary Clarifiers Rehabilitation Alternatives Analysis The main disadvantage of the squircular geometry is that it requires the use of corner sweeps, which requires additional maintenance and increases by approximately $100,000 the cost of replacing the mechanism of the four secondary clarifiers, offsetting some of the savings realized by keeping the existing basin geometry. The main advantage of the circular basin geometry is that it eliminates the need of corner sweeps. However, the circular geometry reduces the existing clarifier capacity. It is also the most expensive basin geometry and will likely require the longest construction timeframe. The filleted basin geometry is a blend of the squircular and circular geometry concepts. The main advantage of the filleted basin geometry is that it eliminates the need of corner sweeps at a much lower cost, and potentially construction duration, than the circular basin geometry. The main disadvantage of the filleted basin geometry is that it also reduces the existing clarifier capacity. Cost -wise, this geometry is about $500,000 higher than the squircular geometry but cheaper by about $900,000 compared with the circular geometry. Thus, based on our analysis, it is our opinion that the high cost of building the circular basin geometry has significant drawbacks and does not provide distinct advantages when compared with the squircular and filleted basin geometries to justify its cost premium. Sludge Removal Mechanism Drat Tubes While this is the existing mechanism being used by the squircular basins at the WWTP and have been in service for almost four decades, the draft tubes mechanism is not recommended in contemporary applications for the following reasons4: O The draft tube mechanism occupies a considerably greater space above the sludge collection zone and may interfere with settling. O Control of the RAS flow rate is difficult with the this type of mechanism due to the difficulties in setting the valves in the RAS box with variable sludge quantities and sludge rheology as well as differences in the hydraulics of the sludge withdrawal tubes. Suction Header For squircular basins, the use of corner sweeps would hinder the operation of a suction header mechanism. C1earStream and Westech have stated that suction headers with corner sweeps are not an ideal application. C1earStream also stated that this mechanism would have to be fitted with dual suction headers if fitted with corner sweepers, which would significantly increase the cost of this type of mechanism for this application. The suction header is the preferred technology for many secondary clarifier applications with basins with circular geometries because of its effectiveness removing sludge and price advantage compared with spiral blade mechanisms. Thus, suction headers may be a good option for this application when circular or filleted basins are selected. 4 Kinnear, Davis J., Evaluating Secondary Clarifier Collector Mechanisms. Water Environment Federation, 2002.

This, coupled with the depth of the sludge blanket (1-4 ft) leave limited space (3-6 ft) between the top of the sludge blanket and the bottom of the influent well. To ensure that no sludge scouring and resuspension of solids when influent flows exit the influent well, and if this mechanism is selected for the rehabilitation, it is recommended that a Computer Fluid Dynamic (CFD) calculations be performed to evaluate if this is a real problem and what mitigation measures are necessary (e.g., baffles, etc.) Spiral Blade Spiral blade is an attractive option if a squircular basin geometry is selected as the corner sweep methodology of "pushing" the sludge is similar to the principle used by the spiral blade mechanism to direct sludge towards the center of the column. For the filleted basin geometry option, because of performance and cost considerations, the spiral blade mechanism is not as attractive compared with the suction header mechanism, if appropriately designed. Recommended Mechanism Material Based on the existing carbon steel performance with appropriate coating and cathodic protection and if initial capital investment is a priority, HDR recommends installation of carbon steel mechanisms in the secondary clarifiers. However, if chemical addition for enhanced settling becomes a possibility or the City would like to reduce maintenance and ensure a longer useful life, then 316 SS would be the preferred material. A preliminary life cycle cost using a 2.8 percent inflation rate indicates that the additional cost of 316 SS can be offset if sufficient operational and maintenance costs are realized by choosing this material over carbon steel. The necessary savings will depend on the timeframe considered: • O&M savings to offset $300k adder for 316SS over a 20-year life cycle = $16,000/yr • O&M savings to offset $300k adder for 316SS over a 30-year life cycle = $10,700/yr • O&M savings to offset $300k adder for 316SS over a 40-year life cycle = $8,200/yr Thus, HDR recommends base bidding with carbon steel for the clarifier mechanisms and including an adder to change the mechanism material to 316 SS. This would allow the City to select a contractor based on the lower carbon steel bid pricing and give the City the option to upgrade to 316 SS at the City's discretion. Pricing of 316 SS can be volatile and dependent on market and commodities conditions. This approach reduces the City's risk of obtaining a high bid due to changes in SS pricing.

More expensive than No. 10. N Also, suction header performs better. Per the analyses conducted, HDR has concluded that the filleted basin with a new suction header mechanism provides the best value to the City for the following reasons: • It is the lowest cost option that eliminates the corner sweeps, which will contribute to reduce maintenance in a confined space and the number of unplanned shutdowns. City of San Mateo 15 Secondary Clarifier Rehabilitation Alternatives Analysis Summary Report August 8, 2014 C:\pwworking\sac\d0591687\028-228748-Secondary Clarifier-2—Final Report.docx Final Summary Report: Secondary Clarifiers Rehabilitation Alternatives Analysis • It will provide a new mechanism that will be installed per the latest seismic and structural codes. • Installing a new mechanism will likely reduce change orders due to differing site conditions. • Installing a new mechanism may reduce warranty issues. • A new mechanism should have a longer useful life than a rehabilitated mechanism. • The suction header technology is considered the most efficient sludge removal mechanism. As indicated in TM No. 3, it is possible that some capacity loss may be experience by adding fillets to the existing squircular basins. Thus, it is recommended that a CFD analysis be conducted as part of the design of this option to determine actual capacity loss and identify mitigation measures for sludge scouring if needed. The preliminary design criteria and probable construction cost for this alternative are provided in Table 3- 10 in TM No. 3. REPLACEMENT OF RAS PUMP DISCHARGE VALVES AND SECONDARY CLARIFIERS INFLUENT GATES (TM No. 4 Summary) RAS Valves It is recommended to replace the existing RAS pump discharge valves with 14-inch 316 SS knife gate valves in accordance with City staff preference. The discharge valve on RAS Pumps No. 1 through 3 will need to be rotated 180-degrees due to the pipe conflict on the east side of RAS Pump No. 3. There are existing conduits to the west side of RAS Pump No. 6 that will need to be relocated so that the rotated knife gate valve can be installed without a conflict. The discharge valves for RAS Pump No.4 through 6 will be installed in the same orientation as the existing Non -Rising Stem (NRS) gate valves. The cost for replacement the six RAS valves would be approximately $78,000. This includes a cost of $7,000 per valve and $2,800 for the installation of each valve plus 10% for Division 1 general requirements and 20% for contingency. This cost does not include City's administration costs, engineering, or construction management. For more details including valve replacement renderings, specifications and manufacturer information, please refer to TM No.4 Secondary Clarifier Influent Gates It is recommended to replace the secondary clarifier influent gates with 316 SS sluice gates similar to the existing gates. The costs for replacement of the four sluice gates would be approximately $86,000. This includes $10,000 for each sluice gate and $5,000 to install each valve plus 10% for Division 1 general requirements and 30% for contingency. This cost does not include City's administration costs, engineering, or construction management. For more details including gate replacement renderings, specifications and manufacturer information, please refer to TM No. 4. City of San Mateo 16 Secondary Clarifier Rehabilitation Alternatives Analysis Summary Report August 8, 2014 C:\pwworking\sac\d0591687\028-228748-Secondary Clarifier_2_Final Report.docx Final Summary Report: Secondary Clarifiers Rehabilitation Alternatives Analysis ESTIMATED PROBABLE OVERALL PROJECT COST An estimate for the probable cost for the overall project is provided in Table 6. In order to provide a complete probable cost for the overall project, Table 6 includes planning level estimates for construction, engineering design, and construction management services. The construction cost estimates tabulated for the rehabilitation of the secondary clarifiers were developed in TM No. 3. The construction cost estimates tabulated for replacement of the RAS pump discharge valves and the secondary clarifier influent gates were developed in TM No. 4. Specific details on the development of these cost elements can be found in these TMs. These cost estimates relied on the following information and assumptions: O All markups (labor, equipment, subcontractor, sale tax, etc.) except escalation are included. O General contract requirements at 10 percent of labor and materials for construction are included in the construction cost estimates. This includes contractor mobilization, demobilization, construction facilities, general conditions, shop drawings/O&M manuals, and facilities startup and testing. O Contingency is assumed at 25 percent for the secondary clarifier rehabilitation, 20 percent for the replacement of the RAS discharge valves, and 30 percent for the replacement of the secondary clarifier influent gates. A higher contingency was used for the gates as the Aeration Basins Effluent Boxes were not inspected and the condition of the concrete within the box is unknown at this time. O Engineering services, including design and engineering support during construction, are estimated at 10 percent of the construction cost. O Construction management services are estimated at 15 percent of the construction cost. This high percent is assumed to account for multiple construction seasons.
