Our History

A public referendum was held to address public sanitation and health concerns along the Fox River, leading to the establishment of the Aurora Sanitary District.

The original trickling filter plant opens with a sewage treatment capacity of 8 million gallons per day , serving a population of 40,000.

The environmental movements of the 1960’s and 70’s resulted in major expansion and upgrades, including Activated Biolsolids treatment.

As the District grows and begins to treat more communities, the name Fox Metro is adopted to reflect the Fox River metropolitan area that we serve.

The Wet Weather Overflow Facility is a large water storage building that allows Fox Metro to intake the excess water flows during heavy rainfalls, preventing contaminated storm water from flowing freely into the Fox River.

The South Plant expansion begins with the goal of removing increased levels of Phosphorous found in wastewater.

The South Plant expansion becomes operational, on-time and under budget.

Fox Metro’s first solar field opens, with a capacity of 2.0 Megawatts. While providing approximately 16% of Fox Metro’s power, the solar field saves roughly $160,000 per year in electricity costs.
