OPERATIONS COMMITTEE MEETING Monday, July 16, 2018 3:30 p.m. Conference Room 1st Floor Present: Richard Solbrig, Shannon Cotulla, John Thiel, Jim Jones, Kelly Sheehan, Heidi Baugh, Star Glaze, Julie Ryan Public: None
A meeting was held to discuss the following:
TOPICS DISCUSSION 1. PUBLIC COMMENTS. None. 2. CONSTRUCTION PROJECTS a) Plant Emergency Generator Replacement (Cal Electro Inc.)
• Cal electro moving forward generally on schedule. Work being completed at Site 1 (Generator) and Site 2 (Breakpoint). Contractor is exposing and removing old utilities. Demolition of old breakpoint structure is occurring this week.
• We will take a tour of the project when there is something other than a hole in the ground.
• During recent abandonments, CEI had their welder subcontractor on site to do the welding job, and 14 hours later the pipe was still not sealed. District ended up having our welder, Chuck Idell, conduct the welding and successfully seal the pipe. We have agreed with CEI that we will provide all the welders for the remainder of the project and back-charge the contractor. This works out to everyone’s advantage for quality and accessibility to the welder. District is pleased, CEI is pleased. b) DVR Irrigation/ C Hydro (Thomas Haen Co)
• We are still having trouble with the communication from the pivot rigs to the ranch house. Issue of ongoing concern with the contractor and supplier.
• We have been irrigating all three fields with recycled water for about 10 days now. Alfalfa is sprouting. Intensive watering is required at this stage.
• Hydroelectric power is off while we are irrigating the alfalfa. We are either irrigating or generating power, but not both.
c) Fallen Leaf Lake (District) • Ongoing work with District crews to complete vacuum station conversions.
• We are working with the FLL Fire Department on the standby generator agreement and expect it to be finalized this week.
• District installed our generator unit and their smaller unit on the pad that will be covered by a shed before winter. These units are now operational.
• FL8 and FL9 conversions are moving forward. Liberty completed the power drop at FL9 and our crews have installed the new electric pumps. New electric station should be online by the end of the week. FL8 retaining wall complete. Our electricians are finishing up the control panel and will set next week. Expect FL8 to be complete by August 15.
• Pumps and Engineering are meeting Thursday to complete the design and planning for conversion at FL6M (the Main Station). This is the final vacuum system component to be abandoned and converted to electric. Completion expected by October 15th.
d) Ponderosa Waterline (Sierra Nevada Construc-tion)
• Paving completed. Project is in closeout phase.
• The 22 water service transfers for this area, with the exception of 3 or 4 who will do the work under their own contractor, will be completed by Thomas Haen Company next season as a component of the Water and Sewer Improvements project that was just bid.
e) Water Meters Phase 4 • Excellent progress. Contractor is installing over 100 meters per week and sometimes as many as 30 a day. Nearly complete in Sierra Tract which is about half the job. At the current pace they will finish this contract by early September. We are considering adding
2
another 250 meters for installation to their contract for this season. These would go in the neighborhood behind Sierra House School. This would allow us to take advantage of current pricing and get more accomplished this year.
f) Marlette Waterline (Thomas Haen Co)
• Thomas Haen Company has been working for the past 4 weeks on service and meter installations. Last week they did a tie-in to the main line down Monument Avenue. Project includes about 110 meters, half of those will needed new service line transfers. We are planning to change order Haen to complete the water service work in 2019.
• Waterline and meters should be complete by August 16. Our intent is to have Marlette completed so we can use the same inspector on the 2018 Water and Sewer Improvement project. g)Fire Hydrants, Service Valves, Force Main Bypass, Pine Valley PRV
aka 2018 Water and Sewer Systems Improvements Project
• Project was awarded to Thomas Haen Company at the Board’s last meeting. We are currently reviewing insurance and bond documents.
• Few other hiccups and modifications for force main and bypass work--Caltrans rejected our initial encroachment application.
• We will meet with Thomas Haen Company on Thursday to discuss the air relief valve at Martin and Rose. Part of the concern in replacing this ARV is the force main shutdown we would need to do to accomplish this.
3. PLANNING / DESIGN
a) Asset Management Program – Buried Assets, Water
• The Engineering department is leading the District-wide asset management program. This program has advanced impressively in the past year, much of that due to the contributions of Jim Kelly, our GIS Analyst, and Brent Goligoski, our Asset Management Analyst. The asset management team has been working to define various asset management programs to not only assess the condition of assets and identify needed projects, but also minimize life cycle costs and increase operational efficiency.
• Julie provided two handouts: one entitled “Asset Management Program, Buried Assets, Water”, and the other “Asset Management Program, Buried Assets, Sewer”. (Both handouts are attached to these meeting notes.)
• These handouts identified category of interest, the program engaged to assess, monitor or define categories of interest, the goals we hope to achieve, and which Departments are responsible for running the programs.
• The items highlighted in yellow are ones we have moved forward with.
• Jim Jones asked if there was a timeline set up for the lists. John said that while some of these are directly related to the CIP, and that there is some focus to support the upcoming 218 process, most of these are potential long-term programs which may be implemented over the next few years depending on the amount of time and funding allocated and in balance with the expected benefits of each program.
• Julie went through the highlighted items of the “Water” list. She will be discussing 5 of the 9 highlighted items at the Board meeting on Thursday.
• Julie will attend the next Operations Committee Meeting and go over the “Sewer” list at that time.
b) Sierra Blvd Waterline • Last we heard, the City will be bidding this project in August. They do not anticipate doing any more than just potholing this season.
c) Keller-Heavenly Improvements • District commented on 30% plans and sent them back to Farr West to continue working on the various design components.
• An important decision is the tank material. We are looking at life-cycle cost. Current analysis shows that the concrete would be less maintenance. Staff visited KGID’s concrete tank. It has a coating on the inside, and consists of pre-constructed concrete
3
panels set in place, then mortar and coated inside and shotcrete the exterior. This particular tank is not the one we are interested in. We are going through another round of tank materials evaluation.
• We are refining our rock hazard mitigation ($500,000 estimated cost).
• We expect to button the previous two items up in the next 30 days.
• Overall project schedule: design by January; SRF Application is in but we will not hear back from them for 6 months and expect a full year before we receive any SRF funding which would put us too late for to bid and construct in 2019. The earliest would be 2020.
• We would like to get the Heavenly Tank rehabbed/coated by 2019, so we can rely on that tank during the 2020 construction.
• We have a separate FEMA application submitted for rock hazard funds.
d) Rocky Point Waterline • This project has resurfaced with fireflow deficiencies and undersized waterlines--lots of 2” and 4” waterlines, leaks and almost no fire hydrants.
• We are at the 90% design stage for this.
• We have about $1.3 million of existing SRF funds to use on this project, likely in 2019 (after dropping Aloha portion of backyard waterlines project).
e) Waterline Replacement /Fire Flow Projects
• We are developing a comprehensive waterline replacement plan. The focus will be on providing fire flow but will also consider aging waterlines, leak history, condition assessment and other factors. At this point, John is estimating about 60 projects in the $1.5M range. Projects are being sized to be attractive for bidders and for overall implementation through design and construction. This is the first cut with many details and efficiencies to be completed as projects come into greater focus.
• We will be prioritizing these projects by the end of the summer and in support of the 218 effort. We will then be refining each project in the next step, perhaps changing project boundaries, looking for constructability improvements, eliminating certain pipeline segments, reducing cost wherever possible, etc.
• We are identifying needs and prioritizing projects. The level of funding and the velocity of implementation will be at the direction of the Board. We will provide prioritized lists of projects with varying implementation schedules depending on a range of funding alternatives.
f) Groundwater Management Planning
South Y Plume Remediation Project:
• Ivo is heading up this work at South Y PCE Cleanup.
• August 8 will be the next public meeting; it is set to take place at the City Offices (airport).
• Latest work is taking place on the Eloise site (between Liberty Utilities and the Moose Lodge). Drilled two test wells on the same site at varying depths—38’ and 64’ deep. Last week Ivo did some aquifer testing and is currently reviewing results for use in the development of alternatives.
g) Sewer Collection System Assessment
• Crews have looked at about 200 of the 368 pipes identified as a representative cross section of different pipe sizes, materials, locations, etc., that are found throughout our system. We are working to reallocate staff to be able to gather more data, as much as possible to inform potential projects for the 218 process.
• Currently we can look at 7-8 pipes per day to collect information, and then it takes about the same amount of time to look at video and code defects in the pipe. Due to our (Prop 218) time crunch we are tapping a third party resource to do at least some of the coding work, which is turning out to be very cost effective.
h) SCADA Communications Study
• Carollo has submitted a proposal for a task order amendment for the next phase of the SCADA Communication study. They have completed their field work and have made
4
recommendations.
• There will be another proposal in the near future for design work on a new tower here at the plant to 115’ so it can see signals coming in. There is potential for a pilot improvement project (installing a relay on Angora tank) with the system at Fallen Leaf Lake (FLL), better enable those radios to talk to the Plant from FLL. 4. OTHER a) El Dorado County Water Agency Projects
• Staff will be meeting with Ken from El Dorado County Water Agency this Wednesday.
• We have not received any confirmation for this fiscal year projects. Expecting some changes in the overall process. b) Engineering Department Staffing Update
• We have an intern from UOP, Ethan, helping on a number of asset management and meter projects.
• We also have a part time engineer (structural) working for us for 999 hours per fiscal year. During the summer however, he needs to work at his other job the majority of the time which allows only 10 hours a week for us. In order to accomplish more work, we are looking into possibly hiring back an intern we used in the past, with no increase to the approved budget for our part time engineer.
c) Recent Operational Issues
• City reported a depression in the pavement along Osgood following our sewer main. District staff had noticed this last year and had crews TV it, but saw no problems. We checked a month ago and again TV’d it. Crews TV’d it again today and still see no problems with the pipe. We think possibly we are getting water in the pipe zone and it is removing backfill. Staff speculates that water may be coming from new drainage ponds in the area related to the Whole Foods complex construction, or maybe something related to the water main, may be exacerbating this—we are looking into it. In the interim, we have coned off the pavement caving over the sewer line.
• Luther Pass Tank 2. Last week a pump crew operator noticed water trickles coming down the concrete foundation below Tank 2 and after testing the water determined that it was sewer (and not groundwater). We took the tank offline, drained it, and identified a crack in the weld where the overflow pipe penetrates the tank floor. Chuck Idell from Heavy Maintenance did a weld repair on that crack. We placed the tank back on line. It has been five days with no further leaking.
