Dry2k: The drought in Georgia
Georgia is facing its fourth consecutive year of droughtGeorgia’s population has grown to over eight millionPredicted growth of 1.3 million people every decadeChattahoochee/Lake Lanier will not supply growth after 2030 without reduced demand or additional water supplies
ICI DefinitionsIndustrial
manufacturers or processors of materials e.g. textile, pulp and paper, metal finishing
Commercialprovide or distribute a product or servicee.g. hotels, restaurants, office buildings
Institutionsdedication to public service (regardless of public/private ownership)e.g. schools, churches, hospitals, government facilities (including water and wastewater utilities)
What is P2AD ?
A non-regulatory division of the Georgia Department of Natural Resources
P2AD 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
P2AD Water/Wastewater Services
Water audits On-site wastewater pollution prevention
and water efficiency assessments Facilitation of water efficiency/waste

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 conversationsbrochures, bill stuffers, fact sheets
Encourage conservation through pretreatment programsMass-based vs. concentration-based effluent limitsRefer ICI customers to P2AD for free, confidential assistancePractice what you preach!
Steps for a Successful Water Efficiency Program
Step 1 – Establish commitment and goalsStep 2 – Line up support and resourcesStep 3 – Conduct water auditStep 4 – Identify and prioritize water management optionsStep 5 – Prepare a plan and implementation scheduleStep 6 – Track results and publicize successStep 7 – Periodically review and revise program
