Riverwood Forcemain Replacement Project (WW-000008-012)

Project Update: May 17, 2021

County engineers considered multiple options to replace the pipe and determined that the optimal method is to install a new parallel pipe and to abandon the existing pipe. The existing forcemain starts from the pump station and discharges to a manhole on Riverwood Road. The project is in the design phase. A definite plan for this project will not be available until after the final design is completed.

Project Background

In 2011 a forcemain condition assessment report determined the forcemain needed rehabilitation or replacement.

Project Description

The main scope of the project is to replace 657 feet of cast iron, four-inch forcemain pipe, that was installed in 1970.

Project Phase

This is the design phase of the project. Due to COVID-19, a public walk of the project area is not scheduled. However, a virtual meeting will be held in the summer of 2021.

Project Benefits

It is expected the new forcemain will serve the surrounding community for at least the next 80 years. Replacement of the forcemain will:

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

Timeline

What to Expect

This project will be awarded to a qualified contractor through a competitive bidding process once design efforts are completed. All work will be supervised by Fairfax County staff. Every effort will be made to minimize disturbances and impacts to public and private areas. Careful consideration will be given to schedule construction activities to minimize disruption in the community. There will be no interruption to existing sanitary sewer service.

Project Cost and Funding Source

The total project estimate is $500,000.

Presentations to the Community

The community meeting information planned for June will be posted to this page shortly after the meeting is held.
