The D.C. Water and Sewer Authority is proposing to formally consider constructing the Potomac River Sewer Tunnel, which could be extended beyond Rock Creek Park and the sewer outflows west of Key Bridge. Construction of this extension will be reviewed by consulting parties at a meeting on Dec. 15 at the D.C. Department of Consumer and Regulatory Affairs, 1100 4th St. SW. Consulting parties should register by Dec. 1 in order participate in the meeting.
Much of the project area falls within the C&O Canal National Historical Park, Rock Creek Park, and the National Mall and the Memorial Parks administrative unit of the National Park Service. DC Water, in cooperation with the Park Service, is preparing an environmental assessment for the proposed project under federal regulations relating to the existing combined sewer overflows. The Potomac tunnel project would reduce discharges in the Potomac River by 93 percent by volume. DC Water will also assess the project’s likely effects on historic properties listed or eligible for listing on the National Register of Historic Places.
