Water use information shall be obtained from the Virginia Department of Health waterworks permit compliance reports, the department groundwater permit compliance reports, department water use reports provided to each local government, or other appropriate available sources. Information shall be reported for the most recent previous annual compilation of such data that is available on the date of submission of the water plan. Each local government shall be responsible for reviewing the water use information for their locality and obtaining this information from any known omissions in the dataset.

1. The population served.

2. The number of service connections.

3. The average and maximum daily withdrawal of groundwater or surface water over the most recent five-year period.

4. The amount of water used on an annual average basis and on an average monthly basis over the most recent five-year period.

5. The peak day water use by month.

6. An estimate of the water used on an average annual basis by self-supplied nonagricultural users of more than 300,000 gallons in any month of surface water and groundwater within the service area of the community water system.

7. An estimate of the amount of water used on an average annual basis by self-supplied agricultural users of more than 300,000 gallons in any month of surface water and groundwater within the service area of the community water system.

8. An estimate of the number of self-supplied users of less than 300,000 gallons in any month of groundwater and an estimate of the total amount of water used by them on an annual average basis within the service area of the community water system.

C. Using information provided by the department and any additional locally identified data, a regional water supply plan shall include an estimate of the water used on an average annual basis by self-supplied nonagricultural users of more than 300,000 gallons in any month of surface water and groundwater outside the service areas of community water systems.

D. Using information provided by the department and any locally identified data, a regional water supply plan shall include an estimate of the amount of water used on an average annual basis by self-supplied agricultural users of more than 300,000 gallons in any month of surface water and groundwater outside the service areas of community water systems.
