The City of Ann Arbor is developing a plan for rehabilitating the City's Water Treatment Plant (WTP). To ensure reliable high-quality water into the future, the City must invest in significant infrastructure investments. The purpose of the Water Treatment Plant Facility Plan is to evaluate the operational, maintenance and regulatory needs of the plant both now and into the future. The project includes strategic planning, an alternatives analysis, a small pilot plant used to evaluate new technology, and community engagement throughout.
