The program emphasizes the construction of facilities for treatment, storage, and distribution, with grants covering up to 35% of estimated construction costs. A local cost share of at least 50% is required, which may be reduced for disadvantaged communities. Applications are accepted year-round, with priority scores determined annually.

Overview

The annual fundable list runs from July 1 to June 30. The State Water Board aims to execute funding agreements for all projects placed on the fundable list during that fiscal year.
