Utility Service Affiliates, a subsidiary of Middlesex Water Company, has been selected by Perth Amboy to operate water and sewer utility divisions.
The new contract commences from January 1, 2019 through to December 31, 2028 and replaces a deal between the two that has been in place for the past 20 years.
The $67 million deal includes Utility Service Affiliates helping the City to realise increased operating efficiencies such as the provision of quality services to consumers.
