Reverse Osmosis Water Treatment Plant
Fort Dodge, IA
In response to evolving water quality regulations and a commitment to improving drinking water for its residents, the City of Fort Dodge partnered with McClure to plan, design, and oversee construction of a new reverse osmosis (RO) water treatment plant. The project aims to significantly reduce water hardness, enabling the City to meet new chloride discharge limits at its wastewater treatment plant while also improving overall drinking water quality.
The RO system not only addresses water hardness but also removes naturally occurring constituents such as ammonia, radium, chloride, and sulfate—making the water safer and more pleasant for consumption. The resulting softer water is expected to reduce household water softening needs, lower appliance maintenance costs, and extend equipment lifespan for residents. The treatment process includes aeration, detention, filtration, membrane softening, and chemical addition, utilizing raw water from the Jordan and Mississippian aquifer wells. The facility was funded through the Drinking Water State Revolving Fund (SRF) and represents a major step forward in sustainable, high-quality water treatment for the Fort Dodge community.
