COVID19 Update 

City of Ann Arbor water system staff are focused on continuing to deliver safe water to our customers for consumption and important daily hygiene. During this unprecedented public health crisis, critical services will continue such as drinking water, waste water, police, fire, emergency operations and waste and recycling pickup.​

The World Health Organization has indicated that “there is no evidence to date that COVID-19 virus has been transmitted via sewerage systems, with or without wastewater treatment." ​


Don't flush wipes and beware of FOG

The 3 Ps.png

It is more important than ever we take simple steps to help keep plumbing and sewer systems clear of clogs. "Flushable wi​pes" 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, "fat​ber​gs". ​

Water distribution

The City is responsible for maintaining over 400 miles of water main, 3,000 hydrants and 8,000 valves that deliver water to homes and businesses. Public Works crews also install, repair and maintain water service lines, water meters and perform backflow prevention inspections.

Sanitary sewer system

Public Works is responsible for inspecting and maintaining over 360 miles of sewer main and 10,300 manholes to ensure the uninterrupted collection of wastewater. Routine cleaning is performed with a high pressure water jet and vacuum cleaning truck, root cutting equipment (if pipe has been infi​l​trated by tree roots) and a video camera is used to assess pipe condition and pinpoint defects. Staff also repair sewer mains and manhole structures as needed.

Stormwater 

In Ann Arbor, all stormwater (and any pollutants carried by stormwater) are discharged, untreated, to the Huron River and its tributaries. To move stormwater, public works staff maintains and repairs 540 miles of stormwater conveyance system as well as 23,000 inlets and catch basins.
