Sanitary sewer cleaning and preventative maintenance currently underway

The City of Kalamazoo is currently performing sanitary sewer cleaning and preventative maintenance. During normal business hours you may notice an increase in the presence of City crews and equipment within your neighborhood.

The work to be completed is root cutting and heavy cleaning of the sanitary sewer main. You may hear or see back pressure of air in your commode or drains. This is the result of material in the sewer passing by your housing service at the sewer main, which is connected to the City sewer main. In order to minimize the possibility of discharge from your floor drains, sink drains, and/or commodes during the use of this hydraulically propelled equipment; please close your commode covers when not in use for the duration of this work.

Also, to prevent sewer odor from coming into your home, we suggest pouring a cup or two of water into each basement floor drain and any infrequently used sink or tub drains. Because water evaporates, this should be done regularly.

Due to the potential of some of the sewer manholes being located in the rear yards, it may be necessary for the City to use some properties as an access to these manholes. Restoration, if any, will be the responsibility of the City to complete.

The amount of time taken in each neighborhood varies depending on size, the quantity of pipe within the neighborhood, and the ease of access to those pipes. The entire system is cleaned every 7-9 years, which is a common level of service in the wastewater industry.

This work is being conducted as a preventative maintenance measure and is not intended to address any specific problems with individual sanitary sewer service laterals.

If you have any questions or concerns related to this work or the city’s sanitary sewer system, please call (269) 337-8148.
