Dry2k: The drought in Georgia
Georgia is facing its fourth consecutive year
of drought
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
             ICI Definitions
Industrial
  manufacturers or processors of materials
  e.g. textile, pulp and paper, metal finishing
Commercial

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!
