6M gallons of wastewater overflows in Accokeek

ACCOKEEK, Md. (AP) - Officials say a valve left in the wrong position led to an overflow of 6 million gallons of diluted wastewater at a plant in Accokeek.

The Washington Suburban Sanitary Commission reported the overflow late Saturday afternoon. It began early Saturday morning and lasted for more than two hours. The commission says the diluted wastewater was contained on the grounds of the Piscataway plant.

The commission says because the valve was left in the wrong position, wastewater flowed to a piece of equipment that was disabled.

Drinking water is not affected by the overflow.

Earlier Saturday, the WSSC said excessive rainfall led to a sewage overflow at a wastewater pumping station in Fort Washington.

The WSSC says untreated, diluted wastewater spilled into Broad Creek for about 2 hours, starting Friday night and ending early Saturday morning. It's not yet clear how much wastewater went into the creek.

The commission says heavy rain overwhelmed the pump station's capacity.

WSSC crews will post signs in the area and clean up the creek as necessary.
