Electrical Cable Injection Project

The City of Naperville’s Department of Public Utilities – Electric will begin a project to upgrade the aging electrical cable in several subdivisions. The work is scheduled to begin April 5 and will continue through November, pending weather or unforeseen circumstances.

Novinium logoThe 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.

Affected Subdivisions

This project will be conducted in an area bounded by Rickert Drive, Sequoia Road, Oswego Road, Plainfield-Naperville Road and West Street. 

Subdivisions include:

  • Buttonwood
  • West Wind Estates
  • Countryside
  • Springbrook Estates
  • The Fields
  • Villas of the Fields
  • Windgate of Three Farms

A map showing the locations of where work will be conducted and the yards that will need to be accessed is available in PDF format.
