Naperville's $190M Wastewater Upgrade on Schedule for 2030 Completion
Naperville plans to complete a $190 million upgrade to its wastewater treatment facility by 2030, addressing aging infrastructure and compliance with environmental standards. The project aims to reduce phosphorus discharge into the DuPage River, contributing to better water quality and addressing broader ecological impacts.

Naperville is advancing a $190 million upgrade to the Springbrook Water Reclamation Center, scheduled for completion by 2030. This project aims to enhance capacity and infrastructure, ensuring compliance with the Illinois Environmental Protection Agency to reduce phosphorus levels discharged into the DuPage River.
The upgrades include a shift in wastewater treatment from an 85%-15% split between the north and south plants to a more balanced 50-50 distribution after completion. Construction is ongoing, with a new biosolids holding tank and advanced sand removal equipment being installed.
Funding sources include municipal bonds, utility rates, and federal support, with a notable contribution of over $1 million from U.S. Rep. Bill Foster. The project has faced no major challenges, attributed to thorough planning that began in 2020, and is supported by the community despite rate increases.
