Indian Run Gravity Sewer Replacement Project (WW-0000028-002-F)

Overview map showing the proposed work.

 

Project Update: September 1, 2021

The project is in the land acquisition phase. The county expects to obtain all required easements by November 2021. Once the easements are acquired, the project will be bid for construction. Construction is expected to begin in the early part of 2022.

Project Background

The purpose of this project is to relocate an existing gravity sewer pipe that crosses the Indian Run stream. The gravity sewer in question is partially exposed (above ground level) in certain segments, and fully exposed as it crosses the stream. Furthermore, a sewer manhole along the stream bank (manhole # 419) has been undermined by the adjacent stream. The exposed pipe segments and the undermined manhole present a potential environmental hazard. The intent of this project is to remove this sewer crossing and relocate the sewer flows via alternative routes.

Project Description

The project involves the installation of new sewer mains near the Columbia Road and Montgomery Street intersection and crossing the Birch Lane cul-de-sac. Further, roughly 640 feet of existing gravity sewer will be abandoned or removed.

Project Location

The project is in Annandale adjacent to and in the Indian Run Stream Valley Park. Road closures are expected near the Columbia Road and Montgomery Street intersection.

Project Phase

The project is nearing the end of the design phase and beginning the land acquisition phase. Once the land acquisition phase is complete (anticipated fall 2021) the project will be advertised to pre-qualified contractors.

Project Benefits

The benefits of the project are:

  • Improve sewer system reliability in the neighborhood.
  • Prevent costly future emergency repairs.
  • Reduce future risk of sanitary sewer overflows.
  • Reduce risks to public health and the environment.

Timeline

Construction activity is expected to begin in winter 2022 and be substantially complete in winter 2023.

Project Cost and Funding Source

Construction of the Indian Run Gravity Sewer Replacement Project is estimated at $2,300,000. Wastewater construction projects are funded through the county’s Capital Improvement Program.
