Sewer Rehabilitation Project - Glover-Archbold Park


DC Water is performing sewer rehabilitation projects throughout the city as part of its Capital Improvement Program (CIP). The proposed Glover-Archbold Park Sewer Rehabilitation project would involve the rehabilitation of sanitary sewer from Van Ness Street, NW to Canal Road, NW. The benefits of this project would include the rehabilitation of an aging sanitary sewer system, improved structural integrity while maintaining adequate hydraulic capacity, and the reduction of stream and groundwater infiltration and potential sanitary sewer overflows.

DC Water is working in cooperation with the NPS, which is the lead agency, to prepare an Environmental Assessment (EA) for the Glover-Archbold Park Sewer Rehabilitation Project as required by the National Environmental Policy Act (NEPA). NEPA regulations mandate that a review period is completed once the EA is made available to the public. At that time stakeholders such as Advisory Neighborhood Commissions and the public will be notified.
