Recycled Water Project – Sharon Heights GCC

∗ Overview of the Recycled Water Project – Sharon Heights GCC ∗ Project Description ∗ Anticipated Costs and Benefits of Project ∗ Timeline and Current Status ∗ Next Steps

Topics

∗ West Bay maintains 200+ miles of sewer mains ∗ West Bay conveys 3.5 MGD to Silicon Valley Clean Water ∗ Sharon Heights Golf & Country Club (SHGCC) is a partner with West Bay on the project and is formalizing a contract. Contract will require SHGCC membership approval. ∗ SHGCC: non-potable water demand of 152 AFY ∗ The West Bay Recycled Water Project – Sharon Heights GCC, will meet the 152 AFY demand, and potentially be expanded to meet other user demands in the future

Project Overview

∗ Phase I (Alternative I) – Supply up to 152 AFY to SHGCC

∗ Wastewater conveyance and pump station ∗ Satellite treatment facility at SHGCC and pump station ∗ Solids discharge pipeline ∗ Recycled Water (RW) conveyance pipeline on SHGCC

∗ Phase I (Alternative II) – Supply up to 84 AFY to SLAC

∗ RW conveyance pipeline

∗ Phase II (Alternative III) – Supply up to 44 AFY (two business parks and HOA)

∗ RW conveyance pipeline
