Dry2k: The drought in Georgia

  • Georgia experienced four years of drought from 1998 through 2002
  • Georgia’s population has grown to over eight million
  • Predicted growth of 1.3 million people every decade
  • Chattahoochee/Lake Lanier will not supply growth after 2030 without reduced demand or additional water supplies

how can water wastewater utilities encourage their non residential customers to conserve water
How can water & wastewater utilities encourage their non-residential customers to conserve water?
  • Educate ICI customers about economic and environmental benefits of conservation
    • one-on-one conversations
    • brochures, bill stuffers, fact sheets
  • Encourage conservation through pretreatment programs
  • Mass-based vs. concentration-based effluent limits
  • Refer ICI customers to P2AD for free, confidential assistance
  • Practice what you preach!

Steps for a Successful Water Efficiency Program

  • Step 1 – Establish commitment and goals
  • Step 2 – Line up support and resources
  • Step 3 – Conduct water audit
  • Step 4 – Identify and prioritize water management options
  • Step 5 – Prepare a plan and implementation schedule
  • Step 6 – Track results and publicize success
  • Step 7 – Periodically review and revise program

Water Audit
  • Collect background information
  • Walk-through survey
  • Water balance
  • Determine true cost of water
    • water and sewer bills
    • energy for heating water and pumping
    • wastewater treatment costs
    • water treatment costs
energy policy act
Energy Policy Act
  • Effective January 1, 1994
  • Water efficiency plumbing standards
  • 5% water savings nationwide by 2010
  • 8% water savings nationwide by 2020
brainstorm and prioritize water efficiency measures
Brainstorm and Prioritize Water Efficiency Measures

Common Efficiency Measures

  • Recycle process water
  • Use domestic water efficiency techniques
  • Change operation practices
  • Adjust cooling tower blowdown
  • Repair leaks
  • Install high pressure, low flow/automatic shut-off spray nozzles
  • Turn off equipment when not in use
  • Water efficient landscaping/irrigation
slide19
Track Results and Publicize Success
  • Internal
    • use bulletin boards , e-mails, and newsletters to post progress reports
    • reward employees
  • External – apply for P2AD’s recognition programs:
    • Pollution Prevention Partners
    • Annual Governor’s Award

Periodically Review Program and Revise Plan & Goals
