Don't flush wipes and beware of FOG
It is more important than ever we take simple steps to help keep plumbing and sewer systems clear of clogs. "Flushable wipes" create blockages in household pipes and municipal sewer systems and should never be flushed down the toilet, nor should facial tissue or paper towels. Combined with fats, oil and greases, which should never be poured down the sink, these products can create enormous, and expensive to remove, "fatbergs".
This website explains easy ways to help keep the Ann Arbor sewer system efficient and functional. Find out what not to flush, how to deal with fat, oil and greases, and how to prevent sewer pipe penetration.
Projects
Facilities Renovations Project (PDF) — This project includes rehabilitating existing structures, upgrading of primary and secondary wastewater treatment processes and replacing aging facilities with new facilities. These renovations will allow the City of Ann Arbor to meet future flow and loading demands, as well as regulatory requirements.
The current WWTP has a design capacity of 29.5 million gallons per day (MGD), and consists of an older West Plant (constructed in the 1930s) and a newer East Plant (constructed in the late 1970s).
