OVERVIEW

As part of its Capital Improvement Program, DC Water will be performing a sanitary sewer rehabilitation project within the Chevy Chase Neighborhood (See back page for construction location map). While extending the service life of this local sewer system, other benefits of this rehabilitation project will include improved structural integrity of the sewer, while also maintaining adequate hydraulic capacity and mitigating potential sanitary sewer overflows.

•    Rehabilitation of approximately 46 manholes along the sewer alignment.
