Y2K Not a "Bug" for Philadelphia Suburban Corporation

Y2K Not a "Bug" for Philadelphia Suburban Corporation Bryn Mawr, PA, January 3, 2000 - Philadelphia Suburban Corporation (NYSE:PSC) is pleased to report that all of the water treatment plants and other mission critical systems at its Philadelphia Suburban Water Company (PSW) and Consumers Water Company (CWC) subsidiaries have been working continuously over the weekend without disruption from Y2K. As a result of its Y2K efforts, both companies have been able to deliver an uninterrupted supply of water to its customers.

We were prepared in case an emergency situation arose due to Y2K, but are very pleased with the way our system handled the changeover from 1999 to 2000, said Roy Stahl, Senior Vice President, Law and Administration for PSC. Because the majority of our systems are not date sensitive, we were confident that Y2K would not have an effect on either company's ability to deliver water to customers.

Because PSW and CWC rely on a continuous supply of electric power to operate its systems, company officials were in close contact with electrical suppliers throughout the night. Stahl said, The electrical suppliers who provide power to PSW and CWC were thoroughly prepared for Y2K and their readiness helped us ensure that a continuous supply of water would be available for our customers on January 1, 2000 and well into the future.

PSC is one of the nation's largest investor-owned water utilities, currently serving 1.8 million residents in Pennsylvania, Ohio, Illinois, New Jersey and Maine.
