Dry2k The drought in Georgia

• Georgia experienced four years of drought from
  1998 through 2002
• Georgias population has grown to over eight
  million

Benefits of Water Efficiency Programs to
Industrial, Commercial, and Institutional
Facilities

• Water and sewer cost savings
• Wastewater treatment savings
• Energy cost savings
• Improved product competitiveness
• Easement of regulatory burdens
• Reduced environmental impact
• Enhanced company image

11
Benefits of Water Efficiency Programs to Water
and Wastewater Utilities

• Increase the life of existing raw water supplies

12
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!

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

• Track Results and Publicize Success
• Internal
• use bulletin boards , e-mails, and newsletters
  to post progress reports
• reward employees
• External apply for P2ADs recognition programs
• Pollution Prevention Partners
• Annual Governors Award
