How this utility’s billing works
Prince William Water (formerly Prince William County Service Authority) operates as a public water authority serving Prince William County and portions of Manassas. 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/customer charges plus metered usage charges for water and sewer; the public residential pages describe monthly billing rather than an increasing-block water tier table.. Bills are generated monthly; meters are read and bills are issued every month, and bills are due within 24 days of the bill date., and a typical residential cost reference is $88.85 estimated monthly water-and-sewer bill for a single-family residential customer using 5,000 gallons, as of 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.
