Virginia Law

A. Each local government within the regional planning area shall provide information documenting existing water use information to assist in the development of the regional water supply plan. A regional water supply plan shall include, at a minimum, current information documenting existing water use as listed in this section for each local government within the regional planning area. 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.

B. A regional water supply plan shall include the following information for each community water system within the regional planning area:

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.

9. An estimate of the disaggregated amounts of water used in categories of use appropriate for the system. Typical categories may include:

a. Residential use;

b. Commercial, institutional, and light industrial (CIL) use;

c. Heavy industrial use;

d. Military water use;

e. Water used in water production processes;

f. Unaccounted for losses;

g. Sales to other community water systems and the names of such systems; or

h. Subtotals of the above categories for all community water systems.

10. To the extent that information or sources of information are provided by the department pursuant to 9VAC25-780-60 for each community water system using stream intakes, a qualitative description of existing in-stream beneficial uses within the planning area or outside the planning area that may be affected by the stream withdrawal.

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.

E. Using information provided by the department and any additionally identified data, a regional water supply plan shall include 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 outside the service areas of community water systems.
