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
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)
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

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!
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
