N/A
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 customers and meeting regulatory requirements.
Specifically, the Facilities Plan identified a long-term strategy to plan improvements at SWRC to comply with the City's National Pollutant Discharge Elimination System (NPDES) permit. It also anticipates future regulations, particularly related to nutrient removal and the South Plant return activated sludge (RAS) and grit improvements were identified as a key project in the plan.
In September 2024, the Water Utilities issued Bid #24-161, South Plant RAS and Grit Improvements. The construction work includes replacing the existing aerated grit system with an improved grit removal system and increasing RAS pumping capacity to accommodate future flows, nutrient removal and Side-Stream Enhanced Biological Phosphorus Removal (S2EBPR).
