History and Overview

Clean Water, Quality Service.
Striving to be the Best.

The Service Authority was created by a resolution of the Board of County Supervisors of Prince William County, Virginia on January 11, 1983. The Authority is chartered by the State Corporation Commission and is an independent public body responsible for providing a comprehensive County-wide drinking water and water reclamation system.

The management of the Authority is vested in an eight-member Board of Directors that is appointed by the Board of County Supervisors. The Authority's Board appoints the General Manager, who is responsible for the daily management of the Authority. The Prince William County Service Authority provides drinking water and water reclamation services to more than 75,000 accounts in the state's second-largest county and one of the top 10 fastest-growing counties in the country*.

The quality drinking water that the Authority provides comes from three sources: Lake Manassas, the Occoquan Reservoir and the Potomac River. Treated water from each of these sources flows to customers in three different parts of the Authority’s service area.

Wastewater from the Authority’s service area is treated at two different facilities in Northern Virginia. The H.L. Mooney Water Reclamation Facility in Woodbridge treats wastewater from the eastern portion of the County. The Upper Occoquan Sewage Authority in Centreville treats wastewater from Authority accounts in western Prince William County.

To meet upcoming state environmental regulations, the Service Authority has embarked on an estimated $150 million upgrade and expansion of the H.L. Mooney Water Reclamation Facility in Woodbridge. The first phase of the planned expansion will significantly lower the amount of nitrogen released from the facility to three parts per million, a level that will be enforced by the Virginia Department of Environmental Quality (DEQ) beginning January 1, 2011.

The current Department of Environmental Quality (DEQ) regulation for effluent nitrogen levels is eight parts per million for wastewater treatment plants that, like the Mooney Facility, discharge into the Potomac estuary. The expansion will also increase the amount of wastewater the plant can treat daily 18 million gallons of inflow per day to 24 million gallons.

The Service Authority is committed to meeting the needs of the growing community and protecting the Chesapeake Bay watershed. The expansion of the Mooney facility will help ensure that customers enjoy continued quality service while at the same time, protecting the environment.

Prince William County is located 35 miles southwest of Washington D.C. and is an integral part of the Washington metropolitan area. The County is traversed by two major interstates, providing access to the metropolitan area and surrounding jurisdictions. The Authority is a well managed, forward-thinking organization and a valued member of the business community.
