CENTRALSAN Jdf A- hom CENTRAL CONTRA COSTA SANITARY DISTRICT July 7, 2022 TO: HONORABLE BOARD OF DIRECTORS FROM: MELODY LABELLA, RESOURCE RECOVERY PROGRAM MANAGER REVIEWED BY: JEAN-MARC PETIT, DIRECTOR OF ENGINEERING AND TECHNICAL SERVICES ROGER S. BAILEY, GENERAL MANAGER SUBJECT: RECEIVE UPDATE AND HOLD DISCUSSION ON THE REEVALUATION OF THE LAMORINDA RECYCLED WATER PROJECT (SHELL PIPELINE) As a result of recent interest expressed by the cities of Lafayette and Orinda and the Town of Moraga (collectively known as Lamorinda), staff engaged Woodard & Curran (W&C)to conduct a high-level feasibility study of options for providing recycled water service to the Lamorinda area for landscape irrigation. Since it is along the route, serving the golf courses at Rossmoor are also included, as they were in the original Lamorinda Project. Potential recycled water alternatives evaluated include: 1. The reuse of a portion of an abandoned Shell pipeline, which was acquired by Central San in 1994 with the vision of using it to distribute recycled water to the Lamorinda area; 2. The use of the Shell pipeline right-of-way to construct a new, larger recycled water pipeline; 3. Construction of a satellite water recycling facility(SW RF) at each of the three major demand sites - the golf courses at Rossmoor, Moraga Country Club and Orinda Country Club; and 4. A larger, regional SW RF located at CSO or an equivalent location. W&C has completed their evaluation and will be attending the Board meeting to review their findings in the attached presentation. This presentation was reviewed by the Real Estate, Environmental & Planning Committee at their meeting on June 15, 2022.

In other communities (especially served by SFPUC), wholesale rates are projected to reach $3,000/AF.

Source:EBMUD Updated Recycled Water Master Plan,2019 Al_�k Woodard-Curran 71 CONCLUSIONS AND NEXT STEPS • The cost of serving recycled water to Rossmoor and Lamorinda continues to be prohibitive without significant external funding. • Since they will be self-funded, satellite water recycling facilities remain a potentially viable way to serve recycled water to the golf courses in Rossmoor, Moraga and Orinda. • Potable reuse is a more cost-effective way to leverage Central San's treated wastewater in EBMUD's service area. • A Memorandum of Understanding (MOU) with Rossmoor, EBMUD and the City of Walnut Creek has been developed and is currently under review by all parties for future consideration. • An MOU between Central San and EBMUD to evaluate recycled water opportunities, including a potable reuse study, is currently under development. Staff will be bringing it to the Board soon. - .- �Y CENTRALSAN 6 July 7, 2022 Regular Board Meeting Agenda Packet- Page 88 of 137 Page 8 of 8 QUESTIONS & DISCUSSION ' 13 7 July 7, 2022 Regular Board Meeting Agenda Packet- Page 89 of 137
