Provider briefing
How this utility’s billing works
Prince William Water (formerly Prince William County Service Authority) operates as a municipal department serving Prince William County and connected service areas. Customers should use the provider’s current account-specific bill and official customer-service instructions as the final authority for deadlines, balances, and service requests.
The published water-rate framework is described as Fixed meter-size service charge plus monthly consumption charge; the utility sets rates through a cost-of-service model.. Bills are generated monthly; the utility describes a monthly bill and monthly fixed service and consumption charges., and a typical residential cost reference is $88.85 estimated water-and-sewer bill for a single-family home using 5,000 gallons per month, based on the utility comparison published for rates effective July 1, 2026.. These descriptions are useful planning benchmarks; actual charges can change with meter size, usage, sewer averaging, local taxes, drought stages, or account-specific fees.
Wastewater and sewer calculation
The monthly bill combines water and wastewater charges. The current customer pages describe fixed service charges based on meter size and consumption charges based on monthly usage; the public summary does not provide a separate residential sewer winter-average formula, so the exact sewer allocation depends on the account tariff and bill.
Meter and infrastructure notes
The account is billed monthly from a meter-based consumption reading. The current public pages do not identify the meter communications technology or a fixed reader route schedule.
