Our Wastewater System

Our wastewater treatment plant, the largest single-site treatment facility in North America, is used as a benchmark for other plants across the Midwest.

In a giant step toward becoming a Utility of the Future, GLWA is transitioning its Wastewater Treatment Plant (WWTP) to a Water Resource Recovery Facility (WRRF), that will ultimately operate on renewable energy. At the end of this process, the WRRF will be energy neutral, meaning the facility will create enough energy to power its own operations, and perhaps even create excess energy that can be fed into the power grid.

Additionally, a new Biosolids Dryer Facility (BDF) has the ability to turn roughly one billion gallons of biosolids into environmentally friendly fertilizer. This alternative to burning or dumping in a landfill will significantly decrease emissions year-over-year.
