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

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
