Sanitary Sewer Cleaning

Sanitary sewer cleaning is a routine operation that results in a debris and blockage-free gravity sanitasewer signry sewer system. During this activity, high-velocity water is sprayed against the internal pipe walls of the city’s sanitary sewer while systematically removing accumulated grease, debris, and sediments.

The Fishers Department of Public Works (DPW) is committed to providing uninterrupted sanitary sewer service. Grease and other debris can form deposits on the internal wall of the sanitary sewer pipe. Over time these deposits can cause blockages and backups in the sanitary sewer. In order to reduce the potential for sewer blockages and backups, Fishers DPW crews clean the sanitary sewer pipe in the city's sewer district annually.

Sanitary sewer cleaning operations will normally be conducted between the hours of 7 a.m. - 3 p.m., Monday through Friday, April through October. To be most effective, sewer cleaning operations will be conducted in an established pattern following the City's sanitary sewer collection system. It may be necessary to conduct emergency sewer cleaning operations at other times.

Fishers DPW crews post signs at the entrances to neighborhoods approximately one week prior to conducting sanitary sewer cleaning operations.


A sign (pictured right) will be displayed to communicate that Fishers Department of Public Works will be cleaning the neighborhood's sewer main lines beginning on the Monday of the week that is posted.

Yearly Clean-Up

Fishers strives to clean the mainline sewers within the district annually to prevent backups and blockages and to ensure sewers are in good condition.
