Sanitary Sewer Rehabilitation

Heavy rainfall events can cause inconvenient and costly damage to property due to sanitary sewer backups. The City of Naperville Water Utilities has implemented a strategic plan to reduce and eliminate the frequency and severity of these backups by reducing stormwater and groundwater infiltration into the sanitary sewer pipe network. This strategic plan has improved our sanitary pipe network significantly in recent years using sewer lining, manhole rehabilitation and pressure testing and grouting of joints.

The City will be hiring contractors to complete this work in 2020 in the following areas: Cress Creek, Brookdale and Will-O-Way subdivisions; neighborhoods east of Washington Street and north of 5th Avenue, as well as the neighborhood east of the downtown area and surrounding the North Central College campus.

Traffic and Parking

This type of work requires large trucks and other equipment. City crews and contractors will place safety cones to keep traffic out of the immediate work area. Work will be performed in small segments and will not affect large areas at any one time. Street closures are very rare. In most cases, traffic flow and parking will be only minimally affected.

Utility Service

The only interruption you may experience is during the actual lining process. You will be asked to not use any water. This includes flushing toilets, doing laundry, showers, etc. for up to four hours duration. We will attempt to notify all affected customers and give enough notice to avoid significant inconvenience.

If you received a notice that the project was going to start on a specific date, and it appears nothing was done, please contact the Water Utility at (630) 420-6137.


You do not need to be home while this work occurs. All the work is done by the outside cleanout and the city's sanitary sewer main.  If access is needed, a city representative will contact you. The contractor will start work at 7 a.m. and stop by 5 p.m. Monday through Friday, weather permitting. 

The contractor will inform you when the work is finished, either verbally or by leaving written notification.


This type of work usually causes very little disruption to pavement and landscape. Any damage that does occur will be professionally restored after completion of each step of the work. 

Following Completion of Work

The newly lined portion of your sanitary sewer service will require little to no maintenance. However, the unlined portion may still need periodic maintenance.

After work is complete, if you smell an odd odor, please call the Water Utility at (630) 420-6137.
