ISELIN, NJ -- (MARKET WIRE) -- 04/18/07 -- Middlesex Water Company (NASDAQ: MSEX), a provider of water, wastewater and related services in New Jersey and Delaware, today filed a rate request with the New Jersey Board of Public Utilities (BPU) for a general increase in water rates for its Middlesex system in New Jersey. The Company, which last filed in May 2005, is requesting an overall increase of approximately 16.5% or $8.9 million over current revenues to support its ongoing capital program and to cover costs of increases in operations, maintenance, labor and benefits, purchased power and taxes, all necessary for the Company to continue providing reliable and quality water service.

If approved, the average residential customer using 2,600 cubic feet (19,448 gallons) of water per quarter would see their bill increase from $89.37 to $104.10, an increase of $14.73. Customers will continue to receive a gallon of treated water delivered to their home for less than a penny per gallon. The proposed increase percentage is being requested to be applied equally to all classes of customers.

"Ensuring safe drinking water for nearly a quarter of a million residents requires ongoing and prudent infrastructure investments," said Dennis W. Doll, President and CEO. "This request includes approximately $23.0 million in investment in utility infrastructure in the Middlesex system since rates were last established in 2005. This request also includes replacement and installation of new water lines, valves and hydrants and improvements to water treatment to enhance service to customers," added Doll.

The rate petition represents an initial step in the regulatory approval process. The rate proposal will next be reviewed and analyzed by the BPU and the Division of Ratepayer Advocate, an agency representing customers. A public hearing on the matter will be held in the Company's service area where customers are welcome to comment on the filing request.

Middlesex Water Company presently serves 59,000 retail customers, representing a population of about 237,000 people in the Townships of Woodbridge, Edison, the Borough of South Plainfield, Carteret, Metuchen, the City of South Amboy, the Township of Clark and the Town of Fortescue in Downe Township in Cumberland County. The Company also provides service under contract to the Boroughs of Highland Park and Sayreville, the Old Bridge Municipal Utilities Authority (MUA), the Marlboro Township MUA, the City of Rahway and, under a special contract, the Township of East Brunswick.
