The City is implementing a Sanitary Sewer Asset Renewal Program, which will provide for the inspection and rehabilitation of all City sanitary sewers, manholes, and City-owned portions of lateral sewers. A total of $36 million has been programmed over the next 10 years as part of the City's Sanitary Sewer Capital Improvement Program. The first phase of inspections included sanitary sewers generally bounded by Commonwealth Avenue, Four Mile Run, Route 1, and the Metro rail lines. Inspections for the first phase began in March 2021 and concluded in December 2021. Second phase inspections, west of Commonwealth Avenue, will begin in June 2022 and will take approximately 9 months to complete.  Sewers and manholes that are found to either be structurally deficient will be rehabilitated, with a rehabilitation program scheduled late 2022/early 2023. This program will help to preserve and protect existing City-owned sewer infrastructure, extend its useful life, and protect against pipe collapses and other emergency repairs. In addition, this project will help to reduce the amount of infiltration and inflow (I&I) into the sanitary sewer system. Excessive amounts of I&I can result in sanitary sewer back-ups into homes and businesses.

The Sanitary Sewer Asset Renewal Program builds on a prior 20-year program the City has implemented to rehabilitate its infrastructure. To date, the City has spent approximately $30 million through rehabilitating over 60 miles of sanitary sewer and repairing close to 3,200 manholes.
