ICI Program Background

ICI Programs becoming more popular

locally and nationally. Natural interest in lowering expenses.

ICI sector consumed 20% of the water in

570 reporting utilities but comprised

only 8% of the customer base.*

* According to the AWWA 1999 Financial and Revenue Survey

Five major components to an ICI

evaluation program:1. Select facilities to receive

an evaluation.

2. Inviting facilities to participate.

3. Conducting the On-Site evaluation.

4. Preparing/Presenting evaluation report.

5. Follow-up.

Selecting Facilities to Evaluate

Sort non-residential billing data by water use and business type. SIC, NAICS, DOR codes

Refine the accounts by water use per measurement parameter.

Compare the water-use rate to the benchmark value for the type of facility.

Mean use per business type. Reorder the list of facilities by potential

water savings.

Inviting Facilities to Participate

Formally invite a select number

of facilities to participate.

As important to the success

of the project as the evaluation.

Can optimize participation by

offering rebates and incentives.

Make lists available to WASCO’s.

Conducting the Evaluation

Rate water use amount from

each water using application. Special process and equipment

Consistency is important.

Measures include operation,

maintenance, retrofitting and

replacement.

Efficiency recommendations/payback

periods related to annual savings Payback = $ to Implement ÷ Annual Savings

Local contractors and vendors

can supply costs

Annual savings is based on

water and sewer rates

Increased savings when tiered

rate structures are in place.

Sample Recommendation

Install low-volume pre-rinse sprayer

Your pre-rinse sprayer(s) near your dish station use: 6 gpm.

We recommend replacing them with a model that uses: 1.6 gpm.

Note: Most major restaurant supply companies now sell models

that use a maximum of 1.6 gpm with no performance issues.

Project Cost:Estimated cost: 75$ per nozzles.

Total project cost: 75$

Savings:Estimated savings: 10.98 ccf per year.

Cost to heat water: 0.50$ per ccf.

Water savings value: 57.32$ (including sewer)

Payback period:This recommendation may pay for itselfwith water and sewer savings in: 1.31 years.

Follow-Up

Three to Six Months following

delivery of the report.

Meet with customer.

Review recommendations.

Review implementations.

Begin savings analysis.

Page 20: Exploring ICI water conservation in your service area

Satisfaction and Effectiveness

One-year after the evaluation Follow up with customer once again

Determine the implementation rate.

Gauge the participant’s satisfaction

using a questionnaire. Measure long term implementation

Customer’s satisfaction with new equipment

Satisfaction with utility personnel

Perceived change in utility bill

Include information about other programs.
