Public Supply Annual Reports and Significant Use

Each year, the District conducts annual surveys of public and private potable water suppliers. These surveys are an important source of data and information that are used to support the District’s water resource programs and initiatives, including water supply planning, water use permitting and water conservation.

Form and instructions

See Significant Use in Section 3.6, Part B of the Water Use Permit Information Manual for details and limitations.
