Water Main Upgrade and Replacement Project - 3000 Block of M Place, SE


As part of its Capital Improvement Program, DC Water will be performing replacement and upgrade of existing water mains through the city. These efforts will help improve water quality and system reliability, increase water pressure in some areas, and maintain adequate flows throughout the system. Work will occur on M Place, SE from Fairlawn Avenue, SE to Minnesota Avenue, SE with occasional impact to 1000 block of 30th Street SE.

Scope of work

The project will be performed in the following phases:

  • Phase I – Replacement of service lines as needed.
  • Phase II – Installation of approximately 800 linear feet of water main along M Place SE, from Fairlawn Avenue SE to Minnesota Avenue, SE.
  • Phase III – Complete surface restoration.


  • Construction start: August 2018
  • Construction completion: December 2018
  • Normal work hours: 7:00 am to 7:30 pm, Monday through Friday
  • The Contractor may work at night or on weekends, dependent upon certain construction activities or inclement weather.

Important information

  • The removal and pruning of public space trees may be necessary and will be minimized wherever possible.
  • During this construction project, there will be installation of temporary bypass piping for some affected homes, as portions of water mains are systematically taken out of service. Homes served by these mains will be temporarily connected to an above ground pipe to maintain water services throughout the work.  
  • Water quality sampling will take place during each phase of temporary water service piping use.
  • If a temporary water service shut-off is necessary at any point during the project, affected residents will be notified 48 hours in advance. All scheduled 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.


  • Flagging operations may be used during each construction phase to maintain traffic in the construction work zone.  All Traffic Control Plans will be approved by the District Department of Transportation (DDOT).
  •     At various times during construction, “No Parking” signs may be placed in certain areas in and around the work zone.  Notifications regarding “No Parking” zones will be posted 72 hours prior to construction, as required by DDOT.


  • DC Water is working closely with DDOT to ensure minimal traffic disruptions during construction. Regular updates will also be provided to the affected Advisory Neighborhood Commissions.
