How this utility’s billing works
Prince William Water (formerly Prince William County Service Authority) - West System operates as a public water authority serving Western Prince William County, including the PWCSA West water system. 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 Monthly fixed service charges by meter size plus consumption charges; the 2026 rate plan takes effect January 1, 2026. The official residential FAQ publishes a typical 3/4-inch, 5,000-gallon combined water-and-sewer bill of $88.85 for 2026, with 2025 at $81.55 and 2027 at $96.05.. Bills are generated monthly; meters are read and billed every month, and bills are due within 24 days of the bill date., and a typical residential cost reference is $88.85 per month for a typical 3/4-inch residential account using 5,000 gallons in 2026, according to the official Prince William Water FAQ. This is the combined water-and-sewer bill and excludes any Yorkshire-area contractor trash charge.. 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
Prince William Water’s monthly bill includes fixed meter-size charges and consumption charges for water and wastewater. The reviewed 2026 FAQ gives the combined 5,000-gallon estimate but the accessible page does not expose the West-system line-item sewer formula or winter-average calculation; the older customer handbook describes sewer adjustments and water/sewer charges separately.
Meter and infrastructure notes
Meters are read and billed every month. The public FAQ says bills may be estimated during inclement weather or other reading difficulties and later reconciled when a physical read occurs; the reviewed pages do not identify the West-system AMI/AMR technology or transmission interval.
