Dry2k: The drought in Georgia
Georgia is facing its fourth consecutive year
of drought
Georgia’s population has grown to over eight
Predicted growth of 1.3 million people every
Chattahoochee/Lake Lanier will not supply
growth after 2030 without reduced demand
or additional water supplies
             ICI Definitions
  manufacturers or processors of materials
  e.g. textile, pulp and paper, metal finishing
  provide or distribute a product or service
  e.g. hotels, restaurants, office buildings
  dedication to public service (regardless of
  public/private ownership)
  e.g. schools, churches, hospitals, government
  facilities (including water and wastewater utilities)

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
   Mass-based vs. concentration-based effluent limits
   Refer ICI customers to P2AD for free, confidential
   Practice what you preach!
