Cost of Service Analysis for the Imperial Irrigation District

Client: Imperial Irrigation District

Location: Imperial, CA

Summary: Imperial Irrigation District (IID) retained Cardno ENTRIX to conduct a cost of service (COS) study of its water department. IID has rights to 3.1 million acre-feet per year of Colorado River water. It distributes 97 percent of its water to agricultural users and the remainder to municipal and industrial users. Costs have risen sharply over the last five years, but the District has been unable to implement higher rates to cover those costs. The primary purpose of the COS study is to analyze the present and projected costs of the water department, current and projected revenues from water sales, and determine the size and likelihood of ongoing deficits.
