The Capital Crescent Trail Sewer Rehabilitation

DC Water will rehabilitate a portion of the Upper Potomac Interceptor Sewer as part of a region wide effort to improve the quality and durability of sewers throughout the Washington Metropolitan Area. Many of the district’s wastewater pipes are more than 50 years old, are in disrepair and have structural defects such as fractures. When this occurs, it may allow infiltration of groundwater into the system. This additional groundwater may cause overflows and inundate the capacity of the sewer mains.  The cleaning and lining of the sewer located within the Capital Crescent Trail will restore a portion of the collection system and prolong the life of the main. The cured-in-place pipe (CIPP) method, allows the installation a liner within the damaged pipe to form a pipe-within-a-pipe. This project, on hand, involves the cleaning and lining of 2,100 feet of the 48-inch Upper Potomac Interceptor and the construction of 6 new precast manholes on the Capital Crescent Trail. The City will also be performing rehabilitation of large water mains throughout the city as part of its Capital Improvement Program. To improve the water system infrastructure in various locations, these projects involve the internal joint seal of large transmission mains that delivers water to various locations in and around the District. These efforts will help improve water quality and system reliability, increase water pressure in some areas, and maintain adequate flows throughout the system.
