Prince William Water is committed to providing reliable water service to its customers today and far into the future. Our ability to provide drinking water and wastewater services for homes, businesses, schools and public facilities throughout much of Prince William County requires a robust infrastructure network.

Each year, Prince William Water adopts a planning document called the Capital Improvement Program (CIP). The CIP identifies projects across a five-year horizon, with a focus on preserving and enhancing Prince William Water’s water and sewer infrastructure.

Our interactive map (linked below) identifies some CIP projects with significant community impact that are currently in the design and construction phases. The map also identifies some projects managed by others – such as the Virginia Department of Transportation, Prince William County and developers – in which Prince William Water system improvements are within the scope of their work.

Bull Run Mountain Well Upgrades

The Prince William Water Board of Directors has approved a Capital Improvement Program (CIP) project to improve the drinking water supply available to its current and potential future customers residing within our area of service on Bull Run Mountain and at Evergreen.  This includes customers who live in Bull Run Mountain Estates and near Evergreen Country Club.

Engineering and hydrogeological analyses began in early 2019. Construction of new wells and piping that will be required to connect these wells to our distribution system is expected to begin in 2024 with a one- to two-year schedule for completion.

  • Improve the well system to ensure adequate water supply, which may involve rehabilitation of existing wells and/or construction of new wells; and
  • Enhance the quality of the water delivered to our customers.

Heritage Hunt Sewage Pump Station Replacement and Force Main

The existing Heritage Hunt Sewage Pumping Station (SPS) will be replaced to increase pumping capacity from 3.6 million gallons per day (MGD) to 7.81 MGD. The new, higher-capacity SPS will be capable of serving the anticipated build-out of residential and commercial developments in and around the Heritage Hunt community. A new 24-inch Force Main will be constructed from the SPS to a location at the corner of Heathcote Boulevard and Route 29.

H.L. Mooney Advanced Water Reclamation Facility Wide Improvements

Prince William Water’s award-winning H.L. Mooney Advanced Water Reclamation Facility (AWRF) in Woodbridge treats up to 24 million gallons of wastewater daily, meeting or exceeding federal and state standards. After treatment at Mooney AWRF, the reclaimed wastewater is released into Neabsco Creek, a tributary of the Potomac River. 

This infrastructure project is designed to improve operational resiliency and service levels, provide additional odor control, and allow the plant to continue meeting regulatory requirements. Project elements include enhancements to several areas of the Mooney facility: primary clarifier odor control upgrade; primary clarifier collection system improvements; primary clarifier electrical improvements; equalization basin modifications; Return Activated Sludge Building pump modifications; additional Ultraviolet equipment; yard valves replacement; supplemental carbon system improvements; alkalinity system upgrades; ferric system improvements; secondary clarifier improvements; plant structural protection and refurbishment.

Occoquan Forest Sewage Pumping Stations 36 and 37 Replacement

Replacement of existing antiquated sewage pumping stations and cast iron force mains to continue providing sewer service to this community. The Occoquan Forest Sewage Pumping Stations were constructed in the early 1970s. The project will reduce maintenance expenses, provide new emergency backup power supplies, and improve safety conditions at the sewage pumping stations.

Route 1 Water Main Replacement Project

This project consists of the replacement of a water transmission main along Route 1 from the Garfield Booster Station (near the intersection of Route 1 and Neabsco Road) running south toward Fuller Heights Road. The purpose of this project is to increase transmission capacity from the Garfield Booster Station to southern portions of the Dumfries Pressure Zone, to improve system reliability and to meet customer demand.

Occoquan River Crossing Project

The Occoquan River Crossing Project is a collaboration between three providers of drinking water: Fairfax Water, Prince William Water, and Virginia American Water. This project consists of designing and constructing two new 42-inch parallel water mains that will cross under the Occoquan River inside a 400-foot-long tunnel and connect to existing water mains on the Prince William County side of the river. In addition, a new water main will be installed to connect Fairfax Water’s Griffith Water Treatment Plant (located in Fairfax County) with the 42-inch water mains at the Occoquan River.

This project also includes the installation of a new drinking water pump at the Griffith Plant and two interconnections between existing water mains in Prince William County: one at Tanyard Hill Road and the other at the Horner Road Commuter Parking Lot.

The engineering design, design schedule, construction schedule, and construction process are being managed by Fairfax Water, with coordination among the three utilities.

Spinnaker Court Sewage Pumping Station, L02 and Force Main

The existing Spinnaker Court Sewage Pumping Station (SPS), constructed in 1970, as a wet well/dry well station will be replaced to upgrade the SPS to the latest codes and standards, and replace the aging structures and equipment. Five hundred feet of new six-inch force main will also be constructed to replace the aging four-inch force main discharging from the SPS to a manhole at Helm Court. The new station will serve the community for many years.

Sudley Road Sewer Main Project

This project aims to increase sewer transmission capacity along the Sudley Road corridor and accommodate anticipated growth. The project involves replacing and installing a new 24-inch ductile iron gravity sanitary sewer. A gravity sewer line is not pressurized and uses the force of gravity to carry sewage. The new sanitary sewer line will be approximately 2,800 feet in length.
