Prince William Water advances Occoquan River Crossing project with Lake Ridge interconnection option

Prince William Water is advancing a project that would add a new drinking-water pump at the Griffith Plant and create two interconnections between existing water mains. One interconnection is planned for Tanyard Hill Road. The second is planned for the Horner Road commuter parking lot, with Lake Ridge listed as an alternate location.

The project, called the Occoquan River Crossing Project, was described in an update dated July 23, 2026. The work is intended to add water-system capacity and resilience in Prince William County. The possible Lake Ridge location makes the project relevant to residents and commuters near the community, although the project description does not say that construction is taking place there.

Lake Ridge remains an alternative site

Prince William Water identifies the Horner Road commuter parking lot as the planned location for one of the two water-main interconnections. Lake Ridge is listed as an alternative for that connection. The project page does not identify Lake Ridge as the final site.

That distinction matters for nearby residents and commuters. A connection at the Horner Road lot could involve infrastructure planning near a commuter facility, while a Lake Ridge connection would place the alternative in a different local setting. The available project description does not provide an engineering finding about how either location would affect water pressure or reliability.

The other interconnection is identified at Tanyard Hill Road. Together, the two connections and the new Griffith Plant pump form the main elements described for the Occoquan River Crossing Project.

Dates and next steps

Prince William Water’s July 23 update does not state a construction start date, project cost or completion date. It also does not announce that the Lake Ridge alternative has been selected. The next publicly identified project detail is therefore the location decision for the second interconnection, along with any later schedule or construction information the utility provides.

The water project comes as the county also moves forward with other infrastructure work in the broader Lake Ridge-area community. Prince William County said it broke ground May 5, 2026, on a new interchange at Prince William Parkway and Minnieville Road. That separate project is intended to improve traffic flow and safety and is not part of the Occoquan River Crossing Project.

For now, the water project’s confirmed scope is two water-main interconnections and a new drinking-water pump at the Griffith Plant. Lake Ridge is part of the planning options for the second connection, but the final location and construction timetable remain to be identified.
