Illinois American Water Announces Agreement To Purchase Granite City’s Wastewater Treatment Facility

Illinois American Water, a subsidiary of American Water, has announced an agreement to purchase the assets of the wastewater treatment plant of the City of Granite City.

The City Council approved the Asset Purchase Agreement on Wednesday evening, April 5, at its council meeting.

The sale would bring approximately 26,000 new wastewater treatment customer connections to Illinois American Water, including approximately 10,500 direct and an additional 15,500 indirect customers in surrounding communities.

“We thank the City Council for its vote of confidence in us and we look forward to growing our partnership with Granite City residents and businesses by providing water and wastewater service and solutions,” said Illinois American Water President Rebecca Losli. “Our company and team of experienced employees are invested in the Granite City community. We are positioned to leverage our resources and expertise and continue to address the needs of the community.”

Illinois American Water will file the proposed sale with the Illinois Commerce Commission (ICC) for approval by the end of 2023 or early 2024. If approved by the ICC, it will be the largest wastewater acquisition by the company.

“We support this agreement with Illinois American Water because it is in the best interests of the Granite City community. It will put our city’s wastewater assets and operations into the highly capable hands of Illinois American Water. We are also able to preserve and transition all jobs for the employees,” said Granite City Mayor Mike Parkinson.
