Mitigation Measure 1: Transfer-Bethany Pipeline
CCWD was awarded State grant funding for this project as part of the Los Vaqueros Reservoir Expansion Project. The Notice of Determination was filed in May 2020. Permitting and preliminary design is expected to start in 2020.
Mitigation Measures 2 and 5: Zone 7-SFPUC/EBMUD Intertie
The intertie is in conceptual phase, and the next steps include discussions between Zone 7 and EBMUD/SFPUC to reach an agreement-in-principle and to proceed with a pipeline alignment study and preliminary design. A 'reliability intertie' was included in Zone 7's FY 18/19 Ten-Year Water System CIP, with current projected in-service date by 2029. With external funding, this project could potentially be accelerated.
Mitigation Measure 3a: ACWD-SFPUC Intertie and Local Supply
This project is at the conceptual level. There are no agreements in place or permits, and this project is not in the ACWD CIP. ACWD together with Union Sanitary District and SFPUC are presently revisiting elements of this concept as part of the Purified Water Feasibility Evaluation.
Mitigation Measure 3b: ACWD-SFPUC Intertie and IPR
The initial IPR Feasibility study is complete. There are no agreements in place, and no permits. ACWD has partially funded in CIP and further studies have been scoped with the SFPUC. This project would benefit from funding for needed near-tern studies for the development and distribution of additional water supplies. ACWD, SFPUC, and Union Sanitary District are currently working on the Purified Water Feasibility Evaluation which is focused on feasibility, regulatory and permitting requirements, and limnological studies at Quarry Lakes.
Mitigation Measure 4: West Side SFPUC-VW Intertie
Planning for the project has not yet commenced.
Mitigation Measure 6: MMWD-EBMUD Intertie
This project is at the conceptual stage. Planning for this project has not yet commenced.
Mitigation Measure 7: Los Vaqueros Reservoir Expansion
CCWD was awarded $459 million in grant funding for this project through the Water Storage Improvement Program. CCWD is working with its project partners on development of a JPA. The Notice of Determination was filed May 2020. Permitting and preliminary design is expected to start in 2020.
Mitigation Measure 8: Walnut Creek Water Treatment Plant Pretreatment Facility
This measure allows EBMUD to treat water from the Sacramento River, Los Vaqueros Reservoir, and other sources, enabling EBMUD to deliver supplies to neighboring water agencies. Planning and pre-design activities are underway for this project. Currently, EBMUD is planning to update the plant in phases. Half of the plant will initially be upgraded to full treatment capability, providing up to 80 MGD. A planned future phase would upgrade the other half of the plant, allowing full treatment up 160 MGD, enough to meet EBMUD’s long-term needs.
Mitigation Measure 9: Regional Desalination Plant
Several agencies have expressed interest in potentially moving forward with the regional desalination project. Several studies and a pilot scale test have been conducted between 2003-2013. With external funding support, environmental review, permitting and design can be initiated. Private funds such as a P3 approach, can be leveraged in addition to public funding as options for this project. Review of water rights and feasibility of exchanges is currently underway. This project may be envisioned in conjunction with the LV Expansion (Measure 7) by some partner agencies.
Mitigation Measure 10: Silicon Valley Advanced Water Purification Center (SVAWPC)
VW continues to collaborate with the Cities of San Jose and Santa Clara in the production of advanced purified water from source water received from the San Jose-Santa Clara Regional Wastewater Facility (RWF). The SVAWPC produces up to 8 MGD of purified water to increase the marketability of the existing recycled water supply, conduct engineering studies, and provide a forum for public education and outreach. VW continues to discuss opportunities to develop additional potable reuse supply with its countywide project partners (i.e. Gilroy, Morgan Hill, San Jose/Santa Clara, Sunnyvale); following up on the VW MOUs with Cites of Palo Alto, Mountain View, Sunnyvale, and SFPUC; as exemplified by its 2020 partnership agreement with Mountain View/Palo Alto to develop potable water reuse.
Mitigation Measure 11: Mid-Peninsula Potable Reuse Exploratory Plan
The SFPUC and BAWSCA along with other non-BARR partners including Redwood City, Cal Water, the City of San Mateo, and Silicon Valley Clean Water are working jointly on this IPR project. The initial assessment showed that IPR can deliver between 6-12 mgd of water to Crystal Springs Reservoir to augment water supply. However, operational challenges need to be investigated further to determine the project design and its water supply benefits. The partner agencies are entering a third phase of feasibility analysis to further evaluate operational scenarios, impacts and opportunities for DPR. External funding can help advance this concept with additional site-specific studies and environmental review
Mitigation Measure 12: Joint Tri-Valley Potable Reuse Feasibility Study
This alternative water supply is one of the options being considered by Zone 7. A feasibility study was completed in 2018, concluding that there are several feasible options. Additional studies will be ongoing over the next 2-3 years to determine the need for potable reuse as a supply alternative, and to narrow down the best potable reuse option/s for the Tri-Valley. External funding will lower the unit cost of this water supply and may make it a more attractive water supply option than other options. The feasibility study can be found here.
Mitigation Measure 13: Regional Advanced Metering Infrastructure (AMI) Feasibility Assessment
VW has developed an Advanced Metering Infrastructure (AMI) Program to encourage the installation of AMI hardware, and to maximize its savings potential by pairing AMI hardware with software that will give real-time water data on an accessible online database, leak alerts, and home water use reports. To maximize participation and flexibility, the District will offer several options for its water retailers, which water retailers may choose to combine. Staff has been establishing cost share agreement with water retailers in Santa Clara County starting in FY21. ACWD is in the Proof of Concept phase of its AMI program and will install approximately 3,300 meters during FY20/21.
Mitigation Measure 14: Del Valle Reservoir Water Supply Storage Project
“Del Valle Reservoir Water Supply Storage Expansion Project” has been modified. The DCP had the original concept of expanding storage. That project has since finished feasibility stage and the work group decided to recommend a project to modify the lake infrastructure to accommodate lowering instead. Benefits include improved emergency / drought access to stored water without severe impacts to Del Valle Recreation, and the ability to capture more local run-off. Reservoir reoperation remains conceptual, however several of the BARR agencies are participating in a consortium to implement an x-band radar system, an essential tool needed to implement an effective Forecast Informed Reservoir Operation program.
Mitigation Measure 15: Bay Area Shared Water Access Program (Previously called Regional Water Market)
EBMUD, acting on behalf of the BARR partners, successfully applied for a $400,000 grant from the U.S. Bureau of Reclamation to provide funding for this project. EBMUD signed the grant agreement on September 20, 2018. A strategy report is currently being developed with input from the Bay Area SWAP Stakeholder Task Force to establish a framework and path forward to support regional access to supplies.
