Cress Creek Sewer Rehabilitation

The City of Naperville Department of Public Utilities-Water is contracting with Performance Pipelining, Inc. (PPI) to install cleanouts and rehabilitate the City's sanitary sewer line in the Cress Creek subdivision between Mill Street and Heatherton Drive and from Ogden Avenue to Bauer Road. The sanitary sewers are located underground in parkways, streets and sidewalks. 

The planned method of rehabilitation is called Cured-In-Place-Pipe (CIPP). This method involves inserting a liner saturated with resin into the old pipe through the use of a cleanout, (which may have to be installed before rehabilitation can take place). The liner is then heated to cure the resin and form a new pipe inside the old one.

This project will take place March 25, 2024 to late September 2024, pending weather and unforeseen circumstances. Crews will generally work from 7 a.m. - 3:30 p.m., Monday - Friday. Occasionally it may be necessary for the schedule to vary or for work to continue beyond 3:30 p.m.

Please note: Cress Creek residents who already have a cleanout installed will not need a new cleanout. These residents will still need to have the liner installed.  

Project Goals:

  • Reliability for sanitary service – As part of Naperville’s commitment to providing services that allow for a high quality of life, this project will clean out and improve the reliability of sanitary sewers. 

  • Improved sanitary sewer system performance – The CIPP method will create a new pipe inside the old pipe, improving the flow of wastewater and reducing the risk of clogs and backups.

  • Reduced risk of sewer backups and overflows – A clogged or damaged sewer lateral can lead to sewer backups and overflows. It can include flooding, property damage, and health hazards. Cleaning out and rehabilitating a sewer lateral can help to prevent these problems from occurring.

  • Reduced maintenance costs – Cleaning out and rehabilitating a sewer lateral can help to reduce maintenance costs.

  • Improved environmental quality – The CIPP method is a trenchless method, which means that there is less disruption to the environment and less pollution from construction.

Construction Impacts and Accessibility

The project is expected to have minimal traffic impacts. Streets in the impacted area will remain open throughout the project’s duration and crews will stay on one side of the road. During construction, signage will be placed at the main intersections to keep residents and drivers informed. Occasionally a worker may need to access a resident’s driveway. If that occurs, the resident will receive 24-hour advance notice. 

Please note: Crews will do their best to minimize the impact of this work on traffic, but residents may experience temporary delays when moving through the construction zone.

Residential Water Service Impacts

Water will not be turned off for this project, but residents may be asked to not use water from sinks, bathrooms, laundry, dishes or drains for up to four hours on the day the new pipe liner is installed. This is because the water could interfere with the liner installation process. Impacted residents will be notified by door hanger 24 hours before the lining is installed.

Project Phases

Phase one: Locate the sewer lateral.

  • Crews will use a camera from the public sewer main to locate the sewer lateral. The sewer lateral is a pipe that connects a home or business to the public sanitary sewer system. The lateral carries wastewater from the home or business to the sewer main, then transports it to a wastewater treatment plant. 

  • A white stake or a small, spray-painted square will mark the cleanout's location. 

Phase two: Install the cleanout.

  • A high-pressure vacuum truck will use water excavation to break ground and expose the lateral. 

  • Crews will install the cleanout and inspect it for leaks. 

  • After crews backfill the trench, a 4- or 6-inch PVC cleanout will be visible at grade. 

  • If workers install the cleanout within a sidewalk, crews will cover it with a cast iron "mini manhole" surrounded by cold patches (i.e., temporary asphalt). 

  • The City of Naperville will rehabilitate any disrupted sidewalk squares or landscape. 

Phase three: Inspect and clean the lateral.

  • Crews will inspect the lateral and clean off all tree roots and other blockages using the cleanout. 

  • PPI will then retrieve an accurate measurement for the liner installation. 

Phase four: Install the liner.

  • Crews will prepare and install the liner using the cleanout and public sewer main, which can take up to four hours. 

  • Please note that PPI will provide 24-hour notice asking that residents not use water from sinks, bathrooms, laundry, dishes, or drains during installation. In addition, PPI will request residents to ensure there is water in all the floor drains to prevent the possibility of sewer gas and odors from entering a home or business.
