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.

Capital Improvement Plan
GLWA’s Capital Improvement Plan (CIP) supports the continuation of major capital asset investments to upgrade the Authority’s aging infrastructure. The five year plan is updated annually to reflect changing system needs, priorities and funding opportunities. Click on Learn More to view our current and historical CIP plans.
Combined Sewer Overflows
GLWA operates and maintains CSO Outfalls and CSO Facilities in accordance with our Michigan Department of Environment, Great Lakes and Energy (EGLE) National Pollutant Discharge Elimination System (NPDES) permit.
Sustaining Our Wastewater System in the 21st Century
GLWA began a Comprehensive Regional Wastewater Master Plan (WWMP) in April 2017 that is looking at the needs of the regional collection system and the WRRF over the next 40 years.
Industrial Waste Control
The Great Lakes Water Authority’s Industrial Waste Control group implements and enforces an Industrial Pretreatment Program (IPP) to regulate the discharge of commercial and industrial waste and wastewater.
