Shelby Park Rehabilitation - Area 8 - Marsden Avenue

The Shelby Park Rehabilitation - Area 8 - Marsden Avenue project was developed to renew aging infrastructure and address overflows by reducing the amount of rainfall that can enter the system through defects. It consists of the evaluation and rehabilitation, as necessary, of approximately 36,200 linear feet of existing gravity sewer, approximately 190 manholes, and associated service laterals within Metro’s rights-of-way and easements.

The rehabilitation work will primarily occur in easements and public roadways. Construction methods will include trenchless technologies (pipe and manhole lining) to minimize excavation in streets and properties. However, some excavation will be necessary on certain streets, in existing easements, and in public rights-of-way for sewer service renewals to individual properties and other repairs. Temporary piping for diversion pumping may be installed on the ground. Roadways and properties disturbed by the work will be restored to their original conditions as closely as possible in a manner that will ensure that MWS can maintain future access to the public sewer infrastructure.

The project is expected to last 12 months, although due to the nature of the work, many locations will not experience any impacts for several months at a time.
