Topics ∗ Overview of the Recycled Water Project – Sharon Heights GCC ∗ Project Description ∗ Anticipated Costs and Benefits of Project ∗ Timeline and Current Status ∗ Next Steps
Project Overview ∗ 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 Description ∗ 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
Project Overview PS WTP 6” RW Delivery to SLAC
Project Description ∗ 0.5 MGD Wastewater treatment plant ∗ Wastewater pump station and conveyance pipeline ∗ Solids disposal pipeline ∗ RW pump station ∗ Recycled water pipeline

Example: Santa Paula Water Recycling Facility ∗ 3.4 MGD MBR facility (7x the footprint of Sharon Heights facility) ∗ Buried process tanks and common wall construction reduce facility footprint ∗ No offensive odors or noise with covered process tanks December 2008 September 2008 June 2009 December 2009
Project Benefits and Costs ∗ Alternative I – SHGCC only ∗ 152 AFY of recycled water ∗ Total Capital Cost: $15.6 M ∗ Annual O&M Costs: $233,000 ∗ Unit Cost, Annualized: $6,100/AF
Project Benefits and Costs ∗ Alternative II – SHGCC and SLAC ∗ Up to 236 AFY of recycled water ∗ Total Capital Cost: $17.1 M ∗ Annual O&M Costs: $258,000 ∗ Unit Cost, Annualized: $4,300/AF
Project Benefits and Costs ∗ Alternative III –SHGCC and other users ∗ Up to 197 AFY of recycled water ∗ Total Capital Cost: $17.2 M ∗ Annual O&M Costs: $248,000 ∗ Unit Cost, Annualized: $5,200/AF
Project Benefits ∗ Create a new non-potable water supply ∗ Increase water reliability in drought conditions ∗ Decrease usage of potable water for non-potable uses ∗ Help City meet 20 by 2020 water conservation goals
Project Status ∗ Market survey completed August 2014 ∗ Facilities Plan completed August 2015 ∗ CEQA – MND adopted December 2015 ∗ State Revolving Fund (SRF) Application Completed December 2015 ∗ Qualify for 1% loan & up to $6M grant ∗ Funding agreement with SWRCB by March 2016
Timeline Phase I (Alternative I): ∗ Design-Build-Operate 2016-2017 ∗ Initial phases 2016: Planning and Coordination, Acquisition and Management, Predesign, Design Review, Permitting ∗ Project Construction: late 2016 - 2017 Phase II (Alternative II) Construction: 2018+ Phase II (Alternative III) Construction: 2019+
Next Steps ∗ Program Management Contracting ∗ Finalize Memorandum of Understanding between West Bay and City of Menlo Park ∗ West Bay & SHGCC contract finalization ∗ Design/Build Procurement ∗ Predesign & Permitting ∗ Funding Coordination ∗ Execute funding agreement with SWRCB ∗ Apply for other grants as appropriate
