Water Rates

Affordability is measured using Environmental Protection Agency (EPA) guidelines, with Prince William Water’s bills being among the lowest in the region and well under affordability thresholds set by EPA standards.

Rates vary due to each utility’s unique priorities, operating conditions and capital needs. Prince William Water is careful to ensure its rates are competitive with surrounding jurisdictions while making the investments necessary to provide clean safe drinking water to its customers and protect the environment. Through these efforts, Prince William Water’s rates remain among the lowest in the region. 

*Rates based on 5,000 gallons per month for a single-family residential home, as of January 2024. 

A typical residential monthly water and sewer bill using 5,000 gallons is $74.35. 

Deferring rate adjustments risks delaying infrastructure projects, leading to higher future increases to address deferred maintenance. 

Setting rates for three years allows for increases to be phased in over time, helping to manage customer financial planning and avoid sudden hikes. 

No, Prince William Water does not receive tax dollars from Prince William County and relies on service fees. 

Prince William Water sets its rates based on the actual cost of service as it does not make a profit. An independent financial consultant, Stantec Consultants, Inc., conducted a rate study for Prince William Water and recommended an adjustment to the rates.

Prince William Water periodically recommends changes to rates to ensure we invest in our system in order to properly maintain our infrastructure, meet environmental regulations, and continue to deliver the quality and reliability our customers expect from us.
