The Easterly Wastewater Treatment Plant is charged with treating wastewater from the easterly portion of the City of Marlborough, to EPA and DEP discharge standards, in a cost effective manner.

East Wastewater Treatment Plant: The Easterly Wastewater Treatment Plant is an advanced wastewater treatment facility designed to handle a daily average flow of 5.50 million gallons per day.  The facility treats sewage from the easterly portion of Marlborough (east of Route 495).  This facility operates under the National Pollution Discharge Elimination System (NPDES) permit issued by a EPA and Massachusetts DEP.  The facility’s current permit has been issued by the regulators and contains stringent phosphorus discharge limits of 0.1 mg/l during the growing season.  Since phosphorus is an element that acts as a fertilizer and promotes weed growth.  As a result of the new permit, it will be necessary to upgrade the facility.  In accordance with our NPDES permit, the proposed upgrades to the plant will take place after the upgrades tothe Westerly Wastewater Treatment Plant are completed.  At this time, it is anticipated that the upgrades could run as high as $40 million.  The impact of the construction and higher operating costs will result in a significant increase to the city’s sewer user fees.
