Memorandum
This memorandum and resolution requests approval of a Professional Services Agreement for professional engineering services with AECOM Great Lakes, Inc. (AECOM) for Water Treatment Plant (WTP) Facility Plan 2022 for a total of $5,060,239.80.

To ensure reliable, high-quality water into the future, the City of Ann Arbor (City) must invest in significant infrastructure improvements. The City of Ann Arbor WTP was constructed in 1938, and the City is still using components of this original infrastructure. Portions of the current plant are over 80 years old and have exceeded their service life. While the plant meets current regulatory requirements for drinking water, this aged and deteriorated infrastructure does not meet current design standards and results in many operational and maintenance issues.

To continue to provide reliable, high-quality services, the City evaluated a range of alternatives. In September 2016, staff presented to City Council a summary of the 2015 Water Treatment Plant Alternatives Evaluation, which recommended rehabilitating portions of the City's water treatment plant in lieu of other options that included purchasing water wholesale from an external provider. The 2015 Study considered criteria such as impact on rates, water quality, environmental stewardship, operational impact, reliability of water supply over the long-term, consistency with the City's strategic priorities, and other criteria.

Since 2015, there have been changes in governance with new Council members, changes in raw water quality with PFAS and Cryptosporidium, the continued migration of 1,4-dioxane, and the formation of the regional water supplier, Great Lakes Water Authority (GLWA). The City felt it prudent to review these changed conditions with City Council and obtain direction.
