Ann Arbor eyes $90M water plant upgrade, water bills expected to jump
ANN ARBOR, MI – Ann Arbor officials are gearing up for a potentially $90 million project to replace aging pre-treatment basins at the city’s water plant. And they’re saying city water customers can expect to see more increases in their water bills in the coming years to pay for it. The plant at 919 Sunset Road, on the city’s northwest side, includes facilities dating back to the 1930s, and the city is looking to replace them starting in 2022. “Some of the challenges we’re facing with the existing pre-treatment basins is deteriorating infrastructure,” said Brian Steglitz, the city’s water treatment manager, mentioning deteriorating concrete and failing mechanical equipment. “There are a lot of moving parts in the old 1938 treatment basins, and keeping them working all the time is a challenge for us,” he said. “The technology is also outdated,” he added. “You can imagine the basins have been in service for close to 80 years and things have changed in that much time. And the way that you do lime softening, which is really the essence of what we’re doing in our pre-treatment basins, has changed in the last 80 years.
