BAILEY, GENERAL MANAGER SUBJECT: RECEIVE UPDATE ON REEVALUATION OF THE LAMORI NDA RECYCLED WATER PROJECT (SHELL PIPELINE) At the October 25, 2021 Real Estate, Environmental and Planning Committee meeting, staff updated the Committee that it would be engaging Woodard & Curran (W&C)to conduct a high-level feasibility study reevaluating the viability of the Lamorinda Recycled Water Project, which would potentially use a portion of an abandoned Shell pipeline, acquired by Central San in 1994, for the purpose of distributing recycled water into EBMUD's service area in the cities of Lafayette and Orinda and the Town of Moraga. W&C has completed their evaluation and will be attending the meeting to review the attached presentation, which summarizes their findings.
