The Sanitary Sewer Collection System conveys wastewater from homes and businesses throughout Rochester to the Water Reclamation Plant for treatment.  The sanitary sewer collection system consists of a network of gravity mains, force mains, inverted siphons, access structures, lift stations and pressure relief points.  There are over 500 miles of city owned sewer pipe and over 12,000 city owned structures.  In addition to structures owned by the city, there are over 28 miles of privately owned sewer pipe and 710 private owned structures that convey the wastewater to the Water Reclamation Plant.


Maintenance of the sanitary sewer collection system is performed by Infrastructure Maintenance Division and Water Reclamation Plant crews.  Maintenance activities details can be found on the following link:  Sewer System Maintenance
