Ypsilanti Community Utilities Authority reports release of waste from truck

It's believed a hatch on the rear of a tank on a vactoring truck wasn't fastened down properly when the truck was servicing the septage station at the plant.

Septage is partially treated waste water material typically taken from septic systems.

The septage poured into up to three storm drains within the plant site, YCUA officials believe. The YCUA used the vactor truck to remove about 600 gallons of material that included septage, flush water and sediment in the catch basins.

The affected drains flow through a detention pond. The gate to the pond was closed at 10:50 a.m., about two hours after the original spill. It is unclear whether the spill released to the Willow Creek Outfall.

E-Coli samples were taken from multiple locations within the plant, both upstream and downstream of the spill. Results will be available in a report to be filed on Monday.
