Ten Subdivision Sanitary Sewer Rehabilitation Project
The City of Naperville Department of Public Utilities-Water is contracting with Visu-Sewer to rehabilitate the sewer mains in 10 subdivisions from July through September 2023, pending weather or unforeseen circumstances. The Water Utility advises residents to look for door tags with project information because Visu-Sewer will determine when they will work in specific neighborhoods based on an analysis of the sewer mains and crew availability. Workers will rehabilitate the sewer mains in these 10 neighborhoods:
- Autumn Run
- County Lakes
- Fairway of Country Lakes
- Green of Country Lakes
- Lake Longwood
- Mc Williams
- Pebblewood Estates
This project to improve the reliability of sanitary sewers aligns with Naperville’s commitment to providing services that allow for a high quality of life. The specific goals of the project include:
1. Enhance the sanitary sewer performance. Create what is essentially a new pipe inside the old pipe using the Cured-In-Place-Pipe (CIPPP) method to increase the wastewater flow. The CIPP method requires minimal excavation and will avert tree loss, landscape damage, and long-term traffic inconveniences.
2. Reduce the risk of sewer backups and overflows. A clogged or damaged sewer main can lead to sewer backups and overflows, which can result in flooding, property damage, and health hazards. Cleaning out and rehabilitating a sewer main can help prevent these problems.
3. Lower maintenance costs. Cleaning out and rehabilitating sewer mains can reduce maintenance costs. This project will help extend the life of the sewer mains by an estimated 50 years.
Construction Impacts and Accessibility
Crews will work from 7 a.m. to 4:30 p.m. daily Monday through Friday, although this schedule may vary without notice, and occasionally it may be necessary that the work continue beyond 4:30 p.m. Workers will include signage and door hangers to inform residents that utility work is taking place to maintain a safe environment for pedestrians, motorists and work crews.
The Water Utility is aware that the work can cause some inconveniences and will make every effort to keep the streets and sidewalks accessible. Motorists should expect temporary delays when traveling through the construction zone. Thank you for your patience as we work to improve Naperville’s infrastructure.
Please note: The Water Utility urges residents to ensure there is water in all the floor drains to prevent the possibility of sewer gas and odors from entering a home. Visu-Sewer will post door tags 24 hours before the pipe liner installation as a reminder to have water in the floor drains.
Residential Water Service Impacts
There will be no water service impact except on the day when crews install the new pipe liner during the curing process. Residents are asked to limit the use of water on the liner installation day since the sanitary service will be blocked off during the installation, and crews use pumps and bypass hoses instead of the sanitary service lines. No resident will be without service for more than 12 hours.
Work Processes and Expectations
Step 1: Cleaning and Televising of the Sewer Main
• Workers will clean the sanitary sewers with high-pressure water to remove all debris.
• Crews will use a camera to view the inside of the pipe on a TV to identify all active service laterals and ensure the main is ready for lining.
Step 2: Install the Liner
• The installation and curing of the CIPP liner require a whole day of work.
• Depending on the location of the sewer maintenance holes, workers may reduce the road to one lane of traffic for all or part of the day.
• There will be pumps and hoses set up to "bypass" the sewage around the work area.
• Residents are asked to limit water use since the sanitary service will be blocked off during installation.
• No resident will be without service for more than 12 hours; however, access to driveways may be restricted during this phase due to the hoses.
• Steam may rise from trucks during the CIPP curing process, and the steam is normal and not a cause for concern.
Step 3: Project Completion
• After workers finish rehabilitation, they will clean the impacted areas and professionally restore any affected lawns.
