St. Cloud Advanced WTF Improvements

St. Cloud, MN

Project Overview

The expansion project required extensive coordination with the existing facility to ensure seamless integration of new infrastructure and systems while minimizing disruptions to ongoing operations. The advanced process improvements and facility upgrades included Liquid Oxygen (LOX) supply equipment and Gaseous Oxygen (GOX) preparation system, an ozone system, an ozone feed room, UV disinfection, filter media conversion, existing clearwell conversion and baffling, remodeling and expansion of administrative office areas.

Two feet of dirt covered the existing facility, including a public park. To perform the extensive construction, Rice Lake had to remove the existing soil to reveal the roof structure. The construction sequence required establishing a temporary laboratory space, and operations staff had to relocate temporarily. The demolition completely gutted the shell and then rebuilt the new process features and administrative areas, consisting of modern offices, a conference room with glass curtain walls, a breakroom, locker rooms, and a complete laboratory. The project included restoring the park after construction.

By closely coordinating construction schedules and communicating effectively, we ensured that the expansion project proceeded smoothly without compromising the plant’s ability to deliver high-quality water to the community.
