(Washington, DC) – DC Water’s contractor will install extensometers on the 800- and 900-blocks of Rhode Island Avenue NE. This work is a part of the Northeast Boundary Tunnel Project (dcwater.com/NEBT). Extensometers are deep borehole monitors installed to measure any soil displacement during the construction of the tunnel. Travel lanes on Rhode Island Avenue NE will be reduced to two lanes around each of the construction locations. Weather permitting, the contractor will install extensometers on the following dates between 9:30 AM and 3:30 PM:

NORTHEAST BOUNDARY TUNNEL PROJECT
The District of Columbia Water and Sewer Authority (DC Water) is implementing its DC Clean Rivers Project for the District’s combined sewer system. The project comprises a system of tunnels and diversion sewers for the capture of combined sewer overflows (CSOs) to Rock Creek and the Anacostia and Potomac Rivers for treatment at DC Water’s Blue Plains Advanced Wastewater Treatment Plant. The DC Clean Rivers Project will reduce CSOs annually by 96 percent throughout the system and by 98 percent for the Anacostia River alone.

The work under the Northeast Boundary Tunnel (NEBT) project consists of a large, deep, sewer tunnel that will increase the capacity of the existing sewer system in the District, significantly mitigating sewer flooding and improving the water quality of the Anacostia River. The tunnel alignment starts south of the RFK Stadium and extends north to Rhode Island Avenue and west to R Street NW.
