Sewer Rehabilitation Project - Soapstone Valley Park


DC Water is performing sewer rehabilitation projects throughout the city as part of its Capital Improvement Program.  This project involves the rehabilitation of sewers in the Soapstone Valley Park, from Connecticut Avenue, NW to Broad Branch Road, NW.  Benefits of this project include the rehabilitation of an aging sewer system, improving structural integrity while maintaining adequate hydraulic capacity, and reducing stream and groundwater infiltration and potential sanitary sewer overflows. In preparation for this project, field investigations and evaluations are being conducted to assess the current condition of the sewers. As the Soapstone Valley Park is a property of National Park Service (NPS), DC Water is also coordinating with NPS on the creation of an environmental assessment (EA).

Scope of work

  • Rehabilitation of approximately 7,200 linear feet of affected sewer pipe within the project area.
  • Rehabilitation and/or replacement of manholes and other sewer infrastructure.


  • Submit Environmental Assessment Public Review Draft: Winter 2017
  • Develop Final Environmental Assessment: Summer 2017

Important information

Alternatives for sewer rehabilitation are currently being defined, evaluated and will be made available in the upcoming EA for public review. DC Water encourages comments and questions when the 30-day public review period for the EA is established. The confirmed schedule for this review period will be provided in future correspondence.
