Wemlinger Water Purification Facility

The Wemlinger Water Purification Facility (WPF) is being upgraded to modernize aging equipment, improve processes, and prepare the plant to treat water from multiple sources. Delivered in three coordinated phases, the project will enhance water quality, expand treatment capacity, and help provide safe, reliable drinking water to Aurora communities for years to come.

    Yes, Aurora Water’s goal is to provide a water system that is nationally recognized for excellent water quality, reliability, resiliency, efficiency, and innovation. As the City invests in the Wemlinger Water Purification Facility and other water infrastructure, we want to build on Aurora Water’s strong track record and continue improving the system for our customers.

     

    Aurora Water has already achieved important benchmarks that demonstrate this commitment. All three of Aurora Water’s drinking water treatment facilities have received the Partnership for Safe Water Phase IV distinction, the highest level of performance recognition offered through the American Water Works Association. Aurora Water was the first utility to have three facilities achieve this distinction. When the third facility received Phase IV recognition in 2016, only 18 treatment facilities nationwide had reached that level. Phase IV recognition reflects a commitment to optimizing treatment processes and managing performance beyond simply meeting regulatory requirements.

     

    Aurora Water has also received Platinum Recognition from the National Association of Clean Water Agencies, the highest level of recognition for regulatory compliance and environmental performance. These national recognitions demonstrate that Aurora Water is already performing at a high level and provide benchmarks for continued improvement.

     

    Looking ahead, Aurora Water will continue to look at water quality, reliability, resiliency, energy use, operating efficiency, technology, and how well the system can respond to changing conditions and customer needs. The Wemlinger project and other infrastructure investments are important parts of that work.

     

    The goal is to do more than simply meet regulatory requirements. It is to make thoughtful investments that maintain the high level of performance Aurora Water has already achieved, while looking for ways to make the system even better. We will continue to use nationally recognized standards and best practices and learn from other utilities, while also sharing what we learn through our own experience.

  • Share Hello. Thanks for the presentation. I can't find here how to access the presentation or see construction diagrams that were part of the presentation. Also question on piping construction on east side of existing beds. When could that possibly start, and for what duration? Sounds like that would start prior to construction of new drying beds?

    The recording of the presentation is expected to be posted next week, between August 17 and August 21. 

    Based on current information, piping and electrical tie-ins may occur at the drying beds and Wemlinger during Phase 2 of construction, when the treatment facility is offline for its winter shutdown—November 2026 through April 2027 and November 2027 through April 2028.

    Yes, this work must be completed before construction of the sediment drying beds can begin.
