SLIDE 2

Introduction

  • Diablo Country Club

– Central Contra Costa County – Established 1914 – 18 hole golf course, tennis club, swimming pool, Clubhouse – EBMUD, Water Purveyor – CCCSD, Wastewater Collection & Treatment

  • Water & Energy Committee

– Implements a Program for Environmental Sustainability including Energy and Water

Project Need

  • Sustainable Water Supply

– No Existing Recycled Water Available – Investigate Potential for Satellite Water Recycling Facility located at Diablo Country Club

Why The Club Is Proposing This Project Now

  • Conservation is the right thing to do
  • Current multi-year drought punctuates

the need for conservation & reclamation

  • Development of a long-term, sustainable

water supply for the Club Operations

  • Rising water costs & drought restrictions

are detrimental

  • Both CCCSD & EBMUD have been

encouraging & supportive

Project Process

  • Irrigation Demand Review

– Irrigation Records – Metered Records – ET Records

  • Source Water Review:

– CCCSD Coordination – Sewer Hydraulic Model Review – Sewer Flow Monitoring and Analysis

slide-8
SLIDE 8

Initial Feasibility Study

  • Treatment Analysis
  • Site Survey Analysis
  • Cost Review
  • Permit Requirements

Design Parameters

  • Capacity to Meet 100% Peak Irrigation

Demand

  • Operational Strategy

– Blended Supply – Recycled Water + Potable Water On Greens (EBMUD) – Capture & Return of Runoff & Drainage Water

Major Project Components

  • Sewage diversion station & pipeline in

Diablo Road

  • Satellite Water Recycling Facility

– Membrane Bio Reactor (MBR) on Diablo CC property

  • Waste discharge back to sewer
  • Recycled water storage

Expanded Storage

  • Provides Assurance for Continued Golf

Play in Case of:

– SRWF Maintenance, – Disruption of Diversion, – Emergencies, Power Failures and – SRWF Shut-Down

  • Minimizes Aesthetic Impacts

Irrigation Demand Update

  • Demand at Project Start

– Average Annual = 248 AFY (0.22 MGD) – Peak = 0.51 mgd

  • “New Normal "Demand

– After Turf Reduction and Drought Conservation Measures – Average Annual Approx. 200 AFY (0.18 MGD)

Sewage Availability Update

  • 60% reduced sewage flow over the past 2

years

  • Result of drought-response
  • Flow Monitoring Results:

– 4/2014 = 0.6 mgd [672AFY] – 12/2015 = 0.27mgd [302AFY]

EBMUD & CCCSD Coordination

  • EBMUD & CCCSD MOUs:

– Outlined Requirements – Open communication

  • Further CCCSD Coordination

– Potential Ownership/Operations Agreement

  • Private Non-profit/Public Agency

Partnership is key
