SAYREVILLE, NJ – The Middlesex County Utilities Authority (MCUA) is celebrating the completion of Flood Mitigation and Restoration Improvements to its Sayreville Pump Station by hosting a ribbon-cutting ceremony at its Sayreville Pump Station on Tuesday, June 22, 2021, at 2:00 p.m.
This $92 Million project fully restores the Pump Station to its full capabilities as one of the largest wastewater pumping stations in the State of New Jersey and protects the facility from flooding up to the levels based on 500-year flood projections.
The Sayreville Pump Station (SPS) is located on approximately 10 acres at 56 Canal Street in Sayreville, NJ. This regional wastewater pumping facility conveys approximately 80 million gallons a day (mgd) of wastewater from 33 municipalities and over 700,000 people which represents 75 percent of MCUA’s service areas in Middlesex, Somerset, and Union counties. The SPS has pumped over 320 mgd during major storm events, delivering all of these communities’ wastewater to the MCUA’s Central Treatment Plant for primary and secondary treatment.
On October 29, 2012, Superstorm Sandy completely inundated and shutdown the entirety of Sayreville Pump Station. The main pumps, control valves, monitoring systems and motors were completely submerged, and critical electrical components were rendered inoperable due to submergence in flood waters.
The MCUA mobilized all available resources to begin emergency restoration of the facility and successfully restarted pumping of 20 mgd on November 3, 2012, with all pumps operational by April 2013. To prevent this from happening in a future severe storm, the MCUA successfully obtained funding through the Federal Emergency Management Agency (FEMA) and the New Jersey Infrastructure Bank (I-Bank) to provide a series of significant upgrades and protective measures to prevent damage from further similar storm events.
The Permanent Restoration and Flood Mitigation Project includes construction of a 1,630-foot-long concrete and steel flood wall system to prevent flood waters and storm surges from overwhelming the pump station, approximately 10-Megawatt standby power facility utilizing three diesel generators and one natural-gas generator, installation of four knife gate valve chambers ranging in size up to 132-inch diameter to control all flow entering the pump station during storm events, relocation and replacement of the existing incoming electrical substation to supply power to the facility, a new stormwater pumping station, and permanent restoration of heating, ventilation and plumbing systems, hydraulic valve controllers, electrical switchgears, replacement of 5kV pump motors and other various specialized systems.
During the last 9 years, MCUA’s continued efforts in the planning, engineering, applications for funding and ultimately construction have focused on the need to upgrade and protect this important asset of MCUA’s treatment system. As part of this successful project, MCUA has worked with its partners including FEMA, NJDEP, NJ I-Bank, Middlesex County Board of County Commissioners, and others to repair and improve the Sayreville Pump Station in preparation for any potential 500-year storm. As of May 2021, with our partners and their dedicated service, the Sayreville Pump Station restoration and upgrades have been completed.
The MCUA has preserved and protected Central New Jersey’s environmental resources through responsible waste management and stewardship of the environment around the Raritan River and Raritan Bay since its creation by the Middlesex County Board of County Commissioners (formerly Freeholders) in 1950. The MCUA manages the County’s wastewater treatment and solid waste services.
