Small Diameter Water Main Replacement - Colonial Village

Overview

As part of its Capital Improvement Program, DC Water is replacing existing 12-inch and smaller cast iron water mains in various locations throughout the city. Construction for this project will occur in the Colonial Village neighborhood. These efforts will help improve water quality and system reliability, increase water pressure in some areas, and maintain adequate flows throughout the system.

Scope of Work

  • Installation of about 4,625 linear feet of 8-inch and 673 linear feet of 12-inch water mains
  • Replacement of service lines (lead and/or other), as needed
  • Replacement of fire hydrants and valves
  • Permanent pavement and surface restoration

Schedule (permit dependent)

Phase 1

  • Construction start: Early November 2019 (tentative)
  • Construction completion: April 2020 (tentative)
  • Normal work hours: 7:00 am – 5:00 pm, Monday through Saturday

Phase 2

  • Construction start: January 2020 (tentative)
  • Construction completion: July 2020 (tentative)

Whenever lane closures are in place, the normal work hours will be modified to the following:

  • 9:30am - 3:30pm, Monday through Friday
  • 7:00am - 7:00pm, Saturday

The contractor may work at night or on weekends during each phase, dependent upon additional construction activities or due to inclement weather.

 Important Information

  • If a planned temporary water service shut-off is necessary, affected residents will be notified 48 hours in advance.  Service interruptions will be minimal.
  • Construction may cause temporary discolored water or low water pressure. If you experience discolored water, flush cold water taps for 15 minutes. If water does not clear, contact the DC Water Drinking Water Division or 24-hr Emergency/Command Center.

Traffic Plans

  • Lane closures may be required daily with approved traffic plans by the District Department of Transportation (DDOT).
  • Notifications regarding “No-Parking” zones will be posted 72 hours prior to construction, in certain areas in and around the job site as required by DDOT.

Partners

DC Water is currently working closely with DDOT to ensure minimal disruption during this project.  Regular updates will also be provided to the affected Advisory Neighborhood Commissions.
