The Clean Water Plant (CWP) in Three Rivers experienced a discharge of biosolids from the treated storage tank via a “foam over” in the early morning hours of Wednesday (April 4).
According to a news release from CWP Director James Baker, the discharge volume was estimated at 600 gallons.
The discharge entered the St. Joseph River through the storm drains in Lincoln Street.
CWP crews responded immediately to stop the discharge and to clean the street.
Water samples will be taken from the river to ensure that there has been no impact to the environment. Due to the dilution factor of the St. Joseph River, which flowed at a rate of 1.5 billion gallons per day during the discharge, there is very little threat to the environment.
The Michigan Department of Environmental Quality (MDEQ) has been notified.
