After some residents in the Clover Hill community experienced basement flooding due to exceptionally high rainfall in May 2018, the Division of Utilities and Solid Waste Management (DUSWM) initiated a project to identify potential sources of inflow and infiltration to the wastewater collection system and make needed repairs to areas of sewer main. In conjunction with this work, DUSWM staff have been working directly with residents to identify problems with private sewer lines that could also be contributing to the problem.
As part of our effort to reduce inflow and infiltration to the sewer mains in the Clover Hill neighborhood, the Division of Utilities and Solid Waste Management (DUSWM) has contracted the services of Pleasants Construction Incorporated and their subcontractor, Mobile Dredging and Video Pipe Services, to rehabilitate sections of sewer main. They began work on November 15, 2018 and the work is expected to be completed by May, weather permitting.
The Contractor will be cleaning sewer lines and applying grout to any joints that were determined to be infiltrating. While you will see equipment staged at manholes throughout the neighborhood, much of the work will be underground. This work is in preparation for Cured-in-Place Pipe (CIPP) process, which is a method to rehabilitate sewer lines that does not require any excavation.
Some residents may be contacted directly by the Contractor to curtail water use for short periods of time if there is a need to perform work on their sewer lateral.
As of mid-April 2019, the sewer grouting work has been completed, and the sewer Cured in Place (CIPP) lining work is approximately 85% complete. Additional (future) grouting is planned, but will not have a start date until additional funding has been identified.
Thank you for your patience and cooperation during this work. Should you have any questions, please do not hesitate to contact DUSWM at (301) 600-1825.
