Replacing South Arlington Ridge Road Water Main

Published on April 21, 2018

  • County Board approves $1.9 million contract

  • New main will run between 23rd Street South and South Nash Street

  • 8" main to be replaced with 12" main

The Arlington County Board today approved a $1.9 million contract (including contingency) to Sagres Construction Corporation to replace a nearly century-old water main along South Arlington Ridge Road, between 23rd Street South and South Nash Street.

The existing 8-inch water main was built in 1927 and has experienced frequent breaks in recent years. It will be replaced with a 12-inch water main that will improve fire flow capacity and support neighborhood demand.

"Arlington continues to invest in replacing, upgrading and repairing our aging infrastructure," Arlington County Board Chair Katie Cristol said. "This project is one of many across the County that are improving our water-sewer system and ensuring that our growing population continues to receive high-quality water and sewer service."

The Board voted unanimously to approve the contract.

The South Arlington Ridge Road water main project is included in the Water Main Replacement/Rehabilitation Program in the County's Capital Improvement Plan, under the Utilities section. The program aims to replace old unlined cast iron pipes, which corrode and cause rusty water and reduce fire flow and fire-fighting capacity, with new pipes.

Sagres Construction Corporation was the lowest responsive bidder of nine companies that bid on the project. The contract includes a 20 percent contingency of $317,475 for any required change orders or increased quantities.

Public engagement

Construction of the project will cause some short-term water service disruptions. Traffic will continue Monday through Friday during construction hours from 9 a.m. to 4 p.m. throughout the work zone(s) in the project area. Staff will update the community on the construction progress through the project's website and staff will attend civic association meetings to inform the Arlington Ridge and Aurora Highlands Civic Associations of the project's details and timeline.

Residents who will be directly impacted will receive letters with project details and a construction schedule and water service disruption notices will be distributed to affected residents before any shutdown. All shutdowns will be limited to the same day construction work hours.


The project is budgeted in the Utilities section of the Fiscal Year 2017-Fiscal Year 2026 Capital Improvement Plan (CIP). Funds are available in the Utility Construction Fund to pay for the project.
