Sewer Rehabilitation Project - Pinehurst, Sherrill and Fenwick


DC Water is performing sewer rehabilitation projects throughout the city as part of its Capital Improvement Program. The Sewer Rehabilitation project includes sewers located in or near Pinehurst Park, Sherrill Drive, Fenwick Drive, and Portal Drive. The existing sewers are comprised of apporximaely 22,000 linear feet of snitary pipe and 107 manholes, most of which were installed between 50 and 75 years ago. The pipes are primarily vitrified clauy and the manholes are made mostly of brick. 

In preparation for this project, thorough evaluations including internal inspections of the pipes and manholes and field investigations are being conducted to assess the condition of the sewers and to inventory the environmental resources that are present.  Because the project will cause impacts on NPS land, DC Water is also coordinating with NPS as the lead federal agency on the preparation of a National Environmental Policy Act (NEPA) document during preliminary design studies. Depending on efficiencies or constraints, the three project areas may be advanced together or separately. Other agencies may also participate.

Scope of work 

  • Rehabilitation of approximately 4 miles or 22,000 of affected sewer pipe
  • Rehabilitation and/or replacement of 107 manholes


  • Field Investigation: Completed
  • Public Review of NEPA Document: To Be Determined
  • Design and Permitting: To Be Determined
  • Construction: To Be Determined

Important information

Design Options are currently being defined, evaluated for avoidance and minimization of environmental impacts, and will be made available during a future 30-day public review period for the NEPA document. Comments during the public review period are encouraged. Additional public meetings may be held if requested, and a public hearing may be held if environmental consequences are determined to be controversial.
