Press Release

BRYN MAWR, Pa. Dec. 6, 2000--

Philadelphia Suburban Corporation (NYSE:PSC) today announced that its Philadelphia Suburban Water Company (PSW) subsidiary has expanded its customer base in Chester County through two acquisitions in West Whiteland and West Goshen Townships. The company also began a series of main extension projects in West Goshen and Westtown Townships that will give private well owners access to PSW's reliable supply of public drinking water.

PSW recently purchased the water system assets of the Linden Court water system, a 30-resident homeowner and condominium development in West Whiteland Township, and purchased the water distribution system that serves three industrial buildings on the former Keystone/MMB Helicopter headquarters property in West Goshen Township.

In addition, PSW will provide water service to approximately 350 residents in West Goshen Township and 50 residents in Westtown Township through its Main Source program, which enables property owners with unreliable private wells to be connected to PSW's distribution system. PSW is installing approximately 10,000 feet of new main and new meters to provide service to these areas at a cost of more than $250,000. Residents will also benefit from improved fire protection services.
