BACKGROUND:
The City of Naperville completed a Facilities Plan for Springbrook Water Reclamation Center (SWRC) in 2021. The Facilities Plan supports the City's Utilities priority of protecting the health and welfare of our residents and meeting regulatory requirements.
The Facilities Plan outlines a long-term strategy for improvements at SWRC to ensure compliance with the City's National Pollutant Discharge Elimination System (NPDES) permit. It also anticipates future regulatory changes, particularly those related to nutrient removal and the South Plant improvements were identified as a key project in the plan.
In March 2025, the Water Utilities issued Bid #25-096, SWRC South Plant Improvements. The project generally includes retrofitting the existing aeration basin into two Return Activated Sludge (RAS) fermenters, constructing four new three-pass aeration basins and two final clarifiers, installing four new blowers and modifying the existing clarifier distribution and collection structures. The work also includes associated electrical and power systems, emergency power connections, flow metering, yard piping, plumbing, structural work, and instrumentation and controls.
