ICI DefinitionsIndustrial
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)
Characteristics of the ICI Sectors Heterogeneous Highly variable water use patterns Wide variety of water uses Factors that affect water use can be
complex Wide variety of water efficiency measures Difficult to establish standard for water
efficiency without a site-specific audit
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, and institutions

Water Audit Objective: assess water uses and costs Collect background information Walk-through survey Flow meter readings Water balance Determine true cost of water
Water and sewer bills Energy for heating water and pumping Wastewater treatment costs Water treatment costs Capital costs for equipment Regulatory and liability costs

Common Water Efficiency Measures
Recycle process/cooling water Plumbing fixture retrofits/replacements Adjust cooling tower blowdown Repair leaks Landscaping conservation techniques Install high pressure, low flow/automatic shut-off
spray nozzles Turn off equipment when not in use

Albuquerque, NM Large Users (>50,000 gpd) Water Conservation
Ordinance adopted in 1998 Existing users must convert to low-flow fixtures by 2004 New and existing users must submit a water conservation
plan for approval including baseline, goals, measures, etc. Landscaping requirements of any new development
(except single-family) Option 1- 20% high water use plants; remaining 80%
must be low or medium water use Option 2- water budget based on landscaping square
footage; usage over budget surcharged
Albuquerque, NM City-owned properties required to use
drought tolerant plants. Water budgets set for public parks and public and private golf courses

Considerations for developing an ICI conservation programWhat is the percentage of ICI water demand for your
system?Who are the top users in your customer base?Advantages
Fewer customers to target Potential water savings are greater per customer
compared to residential
Disadvantages More $ per customer compared to residential Requires staff with technical expertise
