3. 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

4. ICI Definitions Industrial manufacturers or processors of materials e.g. textile, pulp and paper, metal finishing Commercial provide or distribute a product or service e.g. hotels, restaurants, office buildings Institutions dedication to public service (regardless of public/private ownership) e.g. schools, churches, hospitals, government facilities (including water and wastewater utilities)

5. What is P 2 AD ? A non-regulatory division of the Georgia Department of Natural Resources P 2 AD provides confidential, free assistance to clients who want to reduce resource usage, waste, and emissions. These services are available to all Georgia manufacturers, commercial businesses, institutions, and farmers

6. P 2 AD Water/Wastewater Services  Water audits  On-site wastewater pollution prevention and water efficiency assessments  Facilitation of water efficiency/waste reduction teams  Information center  Workshops and onsite training  Recognition programs

11. Benefits of Water Efficiency Programs to Water and Wastewater Utilities Increase the life of existing raw water supplies Minimize the impact of drought Postpone water and sewer infrastructure development Water and wastewater treatment operations savings energy savings chemical savings sludge handling savings $

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 P 2 AD for free, confidential assistance Practice what you preach!

13. 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
