Faulty valve causes overflow

Doug Humbert, director of the Three Rivers Wastewater Treatment Plant, said plant officials were notified of a faulty air-release valve last week on U.S.-131.
The incident was reported at 2:35 p.m. Wednesday.
Humbert said the malfunctioning ARV caused a sanitary sewage overflow onto the roadway.
Plant personnel have isolated the malfunctioning valve until repairs can be made. Upon inspection, workers found that less than two gallons of untreated sewage remained around the faulty air release valve vent.
Clean-up personnel checked for debris then covered the affected area with hydrated lime as an additional safety measure.
No surface waters were impacted by the incident and staff made the required notifications to Michigan Department of Environmental Quality and the Branch-Hillsdale-St. Joseph County Health Department.
