Electrical Cable Injection Project
The City of Naperville’s Department of Public Utilities – Electric will continue a project to upgrade the aging electrical cable in several subdivisions. The next round of work is scheduled to begin April 29, 2019, and will continue throughout the summer in several subdivisions including Old Farm, Old Sawmill, River Oaks, River Mist and the Coach Houses of Old Sawmill.
Cable replacement will begin May 8, 2019, in the Farmstead and University Heights subdivisions.
The Electric Utility is working with a company called Novinium that will test and fill the cracks, which have developed over time in the protective insulation of underground electrical cables. This injection process will extend the life of the cable for a minimum of 20 years and will help prevent future cable failures and power outages. It is a cost-effective measure in maintaining the reliability and longevity of the underground electrical system.
Subdivisions were chosen that had the highest failure rate of underground cables due to several factors including age, soil composition and water table height.
Please be aware that utility workers will be accessing residents’ yards during this project. There are some locations where trees have been planted in the utility easements. Homeowners whose trees need to be trimmed to allow access for utility workers will be notified prior to the work being done.
