Riverwood Forcemain Replacement Project

(Project # WW-000008-012)

A condition assessment study was performed of all cast iron forcemains in the County in 2011. The Riverwood Forcemain was identified as one in need of rehabilitation or replacement.

Project Description

The project consists of replacing the existing 4-inch diameter, 657-foot-long cast iron force main, which was built in 1970, and abandoning the existing one.

Project Location

The project is located in the Mount Vernon District along Riverwood Court. The new forcemain will be installed beginning at the existing Riverwood Pump Station and ending at a manhole in the intersection of Riverwood Road and Riverwood Court.

Project Phase

We are currently nearing the end of the design phase. The project is expected to be advertised for bids in late Spring 2022, with construction beginning in Summer 2022.

Project Benefits

The new force main will serve the surrounding community for foreseeable future. Replacement of the Forcemain will:

  • Reduce the level and frequency of maintenance,
  • Prevent costly emergency repairs,
  • Provide residents with safe and reliable utility infrastructure,
  • Enhance the quality of life for Fairfax County residents, and
  • Reduce risks to public health and the environment.


Finished Detailed Design March 2022
Community Outreach Meeting April 2022
Begin Construction June 2022 *
Finish Construction December 2022 *

* Please note that due to supply chain issues and long lead times for common construction materials, the actual construction begin and finish dates may change.

What to Expect

This project will be awarded to one of the Fairfax County annual construction contractors through a competitive bidding process once the design is complete. All work will be supervised by Fairfax County staff or their designated representatives. Every effort will be made to minimize disturbances and impacts to public and private areas. Careful consideration will be given to scheduling construction activities to minimize interference to the community. There will be no interruption of sanitary sewer service to homes.

Project Cost and Funding Source

The construction value of the Riverwood Force Main Rehabilitation Project is estimated at approximately $1,000,000. Wastewater construction projects are funded through the county’s Capital Improvement Program.

Presentations to the Community

The project was presented to the community during a virtual meeting held on April 14, 2022.
