Major Renovations Reshape Ann Arbor Wastewater Treatment Plant

The City of Ann Arbor has reached substantial completion on renovations to the Ann Arbor Wastewater Treatment Plant, one of the largest capital projects in the city's history.

Walsh Construction served as the general contractor for the renovations and new construction efforts at the facility’s 80-year-old west plant and 40-year-old east plant. The project included rehabilitation of existing flow control structures, demolition and replacement of primary and secondary treatment equipment, construction of new buildings, and other various improvements.



The updated features will enable the treatment plant to meet future flow and loading demands, as well as regulatory requirements. The plant has a design capacity of 29.5 million gallons per day.

The Ann Arbor Wastewater Treatment Plant serves as the primary source of collection, treatment and environmentally acceptable discharge of waste water for the Ann Arbor community, including the University of Michigan. In total, the plant services more than 150,000 residents.



Construction operations were strategically phased to allow half of the plant to remain operational while work was being performed. Completion of work was achieved with zero lost time due to injury, the result of a successful partnership between the City of Ann Arbor, Walsh Construction, Arcadis, subcontractors, the Michigan Occupational Safety and Health Administration (MIOSH) and Michigan Department of Licensing and Regulatory Affairs (LARA), which set the highest standards for workplace safety.
