           Middlesex Water Signs Contract to Acquire Wastewater System
                              in Sussex County, DE

         ISELIN, NJ (March 1, 2007) Middlesex Water Company (NASDAQ Global
Select Market: MSEX), a provider of water and wastewater services in New Jersey
and Delaware, today announced it has signed a contract to acquire the wastewater
collection and treatment system of the Town of Milton, Delaware through its
wholly owned, regulated Delaware subsidiary, Tidewater Utilities.

         This collection system and treatment plant presently serves
approximately 740 customers. Tidewater intends to construct a new
state-of-the-art treatment plant to serve both the existing Town residents as
well as several thousand new customers projected in areas surrounding the Town.
The new plant is anticipated to be constructed as development occurs over the
next several years after which, the existing plant will be decommissioned by
Tidewater.

         "We are very excited about being part of this solution that links the
Town of Milton's commitment to meet the present and future needs of its
residents with our company's objectives to develop regional water and wastewater
solutions at affordable rates," said Dennis W. Doll, President and CEO of
Middlesex Water Company. "This is exactly the kind of public/private partnership
our company looks to establish where the foresight and determination of local
officials to establish good public policy can be realized with the assistance of
private enterprise. This approach is a win for all parties involved, especially
for the current and future residents of Milton and the surrounding areas."

         Middlesex Water, established in 1897, is a New Jersey provider of
water, wastewater and related services. Tidewater and its affiliated Delaware
companies provide service to about 30,000 retail water customers. For
