Indian Run Gravity Sewer Replacement Project

Project Number: WW-0000028-002-F

map - Indian Run Gravity Sewer Replacement — *Overview map showing the proposed work.*

Project Update: March 6, 2024

Flippo Construction Company Inc. is working on the Columbia Road and testing the pipes between MH 183 through MH 182. Bypass removal will start next week. Tie-In for both Laterals to MH 13 is in progress.

On Birch Lane Flippo is connecting the Laterals for Lot 2 & Lot 3 to the 8” C900 main sewer pipe. Testing the pipe between MH002 – MH082.

Had a Pre-construction meeting with Flippo & EQR, their Stream restoration subcontractor in the month of Feb 2024. Contractor plans to start the work on the week of Mar 18, 2024

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 in construction phase.

Timeline

Construction started on June 7, 2023, and is expected to be complete in July 2024.

Project Cost and Funding Source

Construction of the Indian Run Gravity Sewer Replacement Project is estimated to be between $1.5 million and $2.5 million. Wastewater construction projects are funded through the County’s Capital Improvement Program.
