Sewer Manholes

Sewer maintenance holes, or "sewer manholes",as they are commonly referred to, are built out of concrete and provide a human access point for the maintenance of the sanitary sewer system.  These manholes come in a variety of sizes, but the most common are 48" and 60" diameter manholes.

Manholes are located in the city right-of-way along the path of the sewer main and are installed at approximately every 300 LF to 400 LF of sewer main line and are also built at intersecting main lines and at turns in the main line.
