Body
SUMMARY:
The Rinconada Water Treatment Plant (RWTP) Interim Site Restoration Project (Project) will complete work that is important to daily plant operations and which was not finished as part of Valley Water’s previous RWTP Reliability Improvement Project (Reliability Project). This new Project scope was collaboratively developed by Valley Water staff in the Capital, Maintenance, and Operations Units.
The successful completion of this Project will support both the current and future phases of work. Major items of work include paving, grading, drainage, and stabilization of disturbed areas to restore road and slope surfaces which will prevent erosion and sediment transport. The work also includes installation of drainage infrastructure and removal of temporary sump pumps, and other miscellaneous mechanical work associated with process pumps and piping.
Project Background
The RWTP was completed in 1967 and is Valley Water’s second largest plant. RWTP has the capacity to deliver up to 80 million gallons of water each day to retailers who then supply residential and commercial users. The RWTP draws water from the South Bay Aqueduct, the San Luis Reservoir, as well as the Anderson and Calero Reservoirs.
On May 26, 2015, the Board awarded a construction contract (Contract) to Balfour Beatty Infrastructure, Inc. (BBII) for the Reliability Project to upgrade the plant to improve reliability while meeting stringent standards for water quality, seismic stability, and safety issues. The work was divided into six phases to allow RWTP to remain online throughout construction.
An amendment to the Contract reduced the scope of work, resulting in BBII completing Phases 1 and 2 of the Reliability Project, and eliminating most of Phases 3, 4, 5, and 6. Completion of the remaining phases cannot immediately resume, as to do so will require repackaging of the plans and specifications to reflect the current status of the work. This Project was initiated to address select outstanding items that are important to the daily operations at RWTP.
Relevant Prior Board Actions
On January 27, 2015, the Board certified the Final Environmental Impact Report (EIR); adopted the Mitigation; Monitoring and Reporting Program, Findings of Fact, and Statement of Overriding Considerations; held a Public Hearing on the Engineer’s Report; adopted a Resolution approving the Engineer’s Report; and approved the Project.
On May 26, 2015, the Board approved the construction contract award to Balfour Beatty Infrastructure, Inc. as the responsible bidder submitting the lowest responsive bid.
On March 10, 2020, the Board approved the amendment to the Reliability Improvement Project’s Construction contract with Balfour Beatty Infrastructure, Inc., reducing their scope of work.
On January 12, 2021, the Board approved the Notice of Completion for the Reliability Improvement Project, thus accepting the work on the Rinconada Water Treatment Plant Reliability Improvement Project, Project No. 93294057, Contract No. C0601, as complete.
Permits
No additional permits are required for this Project.
Next Steps
If the Board approves the recommendations, staff will proceed to advertise for bids for construction. Staff anticipates recommending the Board award a construction contract in June 2021.
FINANCIAL IMPACT:
The Rinconada Water Treatment Reliability Improvement Project is included in the Draft Five-Year 2022-26 Capital Improvement Program (CIP) and in the Board-adopted FY 2020-21 Budget. The estimated construction contract for Rinconada Water Treatment Plant Interim Site Restoration Project is between $2.5 million and $3.5 million. There is sufficient funding in the Fiscal Year 2020-21 Budget to encumber these funds. The Project is funded by the Water Utility Enterprise Fund (Fund 61).
CEQA:
On January 27, 2015, the Board made findings and certified the Final Environmental Impact Report (EIR) for the Rinconada Water Treatment Plant, Reliability Improvement Project (Resolution 15-09). Staff’s recommendation for today’s Board item entails an activity that was included in the Final EIR’s project description; there are no circumstances triggering the need for preparation of a subsequent environmental document.
