As a proud participant in the 2024 St. Louis Green Business Challenge, Missouri American Water continues to set the standard for environmental leadership. During the Challenge year, the company reported on its Champion Innovation Project – the South Water Treatment Plant Intake System Replacement – a transformative upgrade that underscores how essential service providers can also be leaders in clean air and climate resilience.
Through this forward-thinking infrastructure project, Missouri American Water has delivered measurable, high-impact results that support both environmental stewardship and long-term community health. The Clean Air Partnership is pleased to shine a spotlight on the company for its bold commitment to green infrastructure, helping build a cleaner, more sustainable future for the St. Louis region.
“We are excited to reinforce Environmental Stewardship, one of American Water’s core values, with the replacement of this key facility needed to supply safe and reliable water to our customers in South St. Louis County,” said Mattie Zautner, staff engineer for Missouri American Water.
The project included a host of innovative design elements that support both water quality and air quality goals. One of the most critical enhancements was the elevation of all pump motors and electrical components, positioned nearly 10 feet above the record flood level. This unique design helps reduce the risk of flood damage and ensures ongoing system reliability, even during extreme weather events driven by climate change.
In another nod to sustainability, the company installed six new high-efficiency intake pumps, each with a dedicated flow meter to monitor energy performance. These meters offer real-time insights into pump efficiency, helping reduce energy consumption and associated emissions, which are key contributors to the region’s air quality.
To further minimize operational impact, automated water flushing and air burst cleaning systems were added to reduce the need for manual maintenance and maintain optimal system function. Each pump is also equipped with three vibration sensors to detect potential issues early and improve operational efficiency.
Also part of the project, the addition of standby emergency power not only improved resiliency but ensured continued access to clean water without interruption, which is an especially critical service during climate events. Improved site access also supports safer, more efficient service for large vehicles and maintenance crews, which in turn reduces greenhouse gas emissions that have a negative impact on air quality.
