ICI Program Background ICI Programs becoming more popularlocally and nationally. Natural interest in lowering expenses. ICI sector consumed 20% of the water in570 reporting utilities but comprisedonly 8% of the customer base.** According to the AWWA 1999 Financial and Revenue Survey5/17/2011 2 3. ICI Program Components Five major components to an ICIevaluation program: 1. Select facilities to receivean evaluation. 2. Inviting facilities to participate. 3. Conducting the On-Site evaluation. 4. Preparing/Presenting evaluation report. 5. Follow-up.5/17/2011 3 4. Selecting Facilities to Evaluate Sort non-residential billing data bywater use and business type. SIC, NAICS, DOR codes Refine the accounts by water useper measurement parameter. Compare the water-use rate to thebenchmark value for the type of facility. Mean use per business type. Reorder the list of facilities by potentialwater savings.5/17/20114 5.

Inviting Facilities to Participate Formally invite a select numberof facilities to participate. As important to the successof the project as the evaluation. Can optimize participation byoffering rebates and incentives. Make lists available to WASCOs.5/17/2011 6 7. Conducting the Evaluation Rate water use amount fromeach water using application. Special process and equipment Consistency is important. Measures include operation,maintenance, retrofitting andreplacement. 5/17/2011 7 8.

Follow-Up Three to Six Months followingdelivery of the report. Meet with customer. Review recommendations. Review implementations. Begin savings analysis. 5/17/201119 20. Satisfaction and Effectiveness One-year after the evaluation Follow up with customer once again Determine the implementation rate. Gauge the participants satisfaction using a questionnaire. Measure long term implementation Customers satisfaction with new equipment Satisfaction with utility personnel Perceived change in utility bill Include information about other programs. 5/17/201120 21.
