Key Project Improvements

Aurora Water is completing a series of major upgrades at the Wemlinger Water Purification Facility (WPF) and Quincy Reservoir to support new water sources, improve treatment and modernize aging infrastructure. Below is an overview of key elements being built at each site:

Wemlinger Site

• New Pre-Treatment Building - A state-of the art facility that filters out organics and sediment-heavy water. It will allow Wemlinger to clean up to 80 million gallons of water per day.
• Modern Chemical Feed Building - A safer, fully updated space located east of the current chemical room. This building houses new treatment systems, including a carbon dioxide system that helps keep water pH properly balanced.
• Zone 4/5 Pump Station and Surge Tanks - A highly efficient pump facility that reliably moves clean water through Aurora's network of water mains and to customers' taps.
• Filter and Valve Modernization - Complete replacement of internal filter valves and electronic flow meters to reduce future maintenance needs and improve long-term reliability.
• Electrical Upgrades - Replacing older transformers, control centers, and wiring with modern, efficient equipment that supports dependable power and backup systems.

Quincy Site

New Drying Basins - Because the upgraded treatment process will capture more natural sediment and solids from our additional water sources, we are adding three new drying beds at Quincy Reservoir. These basins will safely process and manager the increased solids produced during water treatment.
