Water and Sewer Pro Rata Charges
(Rates Effective February 7, 2007)

Stafford County has adopted a Water and Sewer Pro Rata Policy to finance the water and sewer infrastructure shown in the General Water Improvement Program and General Sewer Improvement Program. The infrastructures financed under the policy include water transmission mains, pumping stations and storage tanks, as well as sewage interceptor sewers, pumping stations and force mains.

The policy is applicable to all subdivisions and site plans, with the exception of family subdivisions. Pro rata charges are based upon the location of the project. Rates for each water pressure zone and sewer shed are expressed in terms of dollars per gallon. The charge for each project is calculated by multiplying the estimated flow for the project by the rate for the project area.

For residential projects, the flow for the project is determined based upon the type of lot (single family or multifamily) and the number of lots. Payment is due prior to recordation of the final plat or upon approval of the final site plan.

For non-residential projects, the flow is determined based on the water meter size, calculated from the number of meter equivalents for each size meter at 350 gallons per day, per meter equivalent. Payment is due concurrently with payment for the water and sewer availability and prior to setting the water meter.

The table below lists project flows in gallons per day for residential projects and common non-residential meter sizes, the current rates for each pressure zone and sewer shed, and the calculated pro rata charges. The maps below illustrate the five pro rata water pressure zones and eight pro rata sewer sheds in the County.
