DC Water has found a significant structural fracture in its 23 foot high trunk, brick sewer main located near 18th Street and D Street NE. Following a thorough investigation of the sewer, it has been determined that there is a need to perform repairs and maintenance procedures to this portion of the sewer immediately. These procedures will require the inspection and cleaning of the sewer while examining the main and repairing structural damage. The project will include entering manholes in the streets to install safety equipment within the main, rehabilitating and strengthening the existing sewer main, and making the necessary repairs to this portion of the sewer main.

Benefits of this project include the rehabilitation of an aging sewer system, improving structural integrity while maintaining adequate hydraulic capacity, reducing stream and groundwater infiltration and potential sewer overflows. In preparation for this project, field investigations and evaluations are being conducted to assess the condition of the sewer.

SCOPE OF WORK
This project involves the internal repairs of approximately 100 linear feet of brick sewer main by utilizing the no-dig trenchless technology, and cleaning and lining of the sewer main.
