MIDDLESEX WATER COMPANY FILES PETITION FOR RATE INCREASE TO RECOVER COSTS FOR WATER QUALITY IMPROVEMENTS

        Iselin, NJ (May 18, 2005) Middlesex Water Company (NASDAQ:MSEX) today filed a petition with the New Jersey Board of Public Utilities (BPU) for a general increase in water rates. The Company, which last filed in November 2003, is requesting an overall increase of $6.4 million over current revenues to support its ongoing capital program and to cover costs of increases in operations, maintenance, depreciation and taxes.

        Since January 2004, the Company has invested $19.2 million in its utility infrastructure, including $8.7 million for a new raw water pipeline to ensure back-up water supply for Middlesex County residents, and $3.8 million to clean and line aging water mains. By June 30, 2005, an additional $4.4 million is expected to be invested for additional maintenance projects such as relining water mains. Approximately $1.1 million will be used towards the completion of a 500 kilowatt solar energy system at the Company’s water treatment plant. The projected savings in energy costs resulting from this project are being passed on to the Company’s customers as an offset to this request for increased rates.

        Dennis G. Sullivan, President and CEO, said Middlesex Water Company is seeking to recover costs associated with rising purchased water costs and capital improvements to its water supply infrastructure. These costs include increases in purchased power, taxes, corporate governance regulation and security, and are necessary for the Company to continue providing reliable and quality water service.

        The average household in the Company’s retail service area is currently charged $28.00 per month for 900 cubic feet or 5,980 gallons of water. The proposed rate increase would mean a water charge of $31.65 per month for 900 cubic feet of water. If the Company’s entire request is approved, rates would increase by 13.06% for residential customers and commercial customers using the average consumption rate.

        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 ratepayers. 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 provides retail water service to approximately 58,000 customers in Woodbridge, Edison, South Plainfield, Carteret, Metuchen and South Amboy. The Company also provides service under contract to Sayreville, the Old Bridge Municipal Utilities Authority (MUA), the Marlboro MUA, East Brunswick, Edison and Highland Park. The increase applies to all classes of customers, both contract and retail.
