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 hired contractors to complete this work in 2022 in the following areas: Cress Creek, Country Lakes, Autumn Run, Pebblewood Estates, Indian Hill, Maple Terrace, Jonester Estates, Brookdale, and McDowell Grace subdivisions; the neighborhood north of Jefferson Avenue and west of West Street, as well as the neighborhoods east of Washington Street and south of North Avenue.

Project Updates

Manhole Rehab: Work will take place in the neighborhood north of Jefferson Avenue and west of West Street. Manholes will be sprayed with a polymer to seal the structures to prevent water infiltration. The contractor for this project will be Spectra Tech.

Large Diameter Lining: The T10 interceptor line that runs along Country Lakes Drive starting on Fairway Drive to Pebblewood Lane just west of Route 59, is expected to be lined later in 2022. This project primarily affects Country Lakes, Autumn Run and Pebblewood Estates subdivisions. The contractor has not yet been determined.

Small Diameter Rehabilitation: The contractor Visu-Sewer will begin this project the second half of 2022 in the Indian Hill, Maple Terrace, Jonester Estates, Brookdale and McDowell area sub-divisions. Work will be broke out into two stages, the first will be along Bauer Road between Columbia and Washington Steet, going north to Ticonderoga Lane. The second is west of Raymond Drive, south of McDowell Road.

Grouting: Work will continue in the Cress Creek subdivision Spring of 2022. Michels Trenchless, Inc is the contractor that will be grouting sewer laterals along Bauer Road, between Heatherton Drive and Royal St. George Drive. Sewer grouting is an effective means of sealing joints which helps in preventing water infiltration.

Sanitary Lateral Rehab: Beginning spring of 2022, Performance Pipelining Inc will be the contractor for this project. Work will take place east of Washington Street and south of North Avenue.  The work entails televising sanitary laterals, installing cleanouts, and lining the laterals where needed.

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.
