Middlesex System
Retail Customers
The Middlesex System in New Jersey provides water services to approximately 61,000 retail customers, primarily in eastern Middlesex County, New Jersey. Areas served on a retail basis include: The Township of Woodbridge, the city of South Amboy, the Boroughs of Carteret and Metuchen, portions of the Township of Edison and the Borough of South Plainfield and a small portion of the Township of Clark in Union County. These retail customers include a mix of residential customers, large industrial concerns, commercial and light industrial facilities.
Contract Customers
The Middlesex System also provides water under wholesale contracts to the City of Rahway, the Townships of Edison and Marlboro, the Boroughs of Highland Park and Sayreville and the Old Bridge Municipal Utilities Authority. Water treatment and pumping services are provided to the Township of East Brunswick under contract. Contract customers of the Middlesex System comprise an area of about 110 square miles with a population of approximately 219,000. Contracts sales to Edison, Old Bridge, Marlboro and Rahway are supplemental to the existing water systems of these customers.
The Middlesex system utilizes both surface and groundwater supplies during various times of the year and customers may receive either or a blend of both sources depending upon location and demands. Surface water is obtained from the Delaware and Raritan Canal (D&R Canal), which is owned by the State of New Jersey and operated by the New Jersey Water Supply Authority. Surface water sources provide approximately 74 percent of the Middlesex system’s supply. Groundwater sources provide approximately 19% of supply from 31 wells and the balance (7 percent) is purchased water from a non-affiliated water utility.
The Company obtains groundwater from its Wellfields in South Plainfield in North and South Edison. Groundwater comes from an underground source of water known as the Brunswick Aquifer. Middlesex Water’s rates are regulated by the New Jersey Board of Public Utilities. The Company is also subject to various Federal and State regulatory agencies concerning water quality standards.
Bayview System
Middlesex Water provides water service to approximately 300 customers in Cumberland County, NJ. This system is not physically interconnected with the Middlesex System. Water supply to Bayview system customers is derived solely from groundwater from an artesian aquifer known as the Lower Kirkwood Formation.
