FOR RELEASE: August 6, 2003 EXHIBIT 99.1 Contact: Cheryl Hansen Director, Investor Relations 610-645-1084 hansenc@suburbanwater.com Donna Alston Manager, Communications 610-645-1095 alstond@suburbanwater.com PHILADELPHIA SUBURBAN CORPORATION REPORTS OPERATING RESULTS FOR SECOND QUARTER 2003 Company Reports Acquisition of AquaSource Immediately Accretive BRYN MAWR, PA, August 6, 2003 - Philadelphia Suburban Corporation (NYSE:PSC) today reported $0.22 in net income per diluted share for the quarter ended June 30, 2003, compared to $0.21 per diluted share last year--or a five percent increase. Corresponding net income increased to $15.2 million, from $14.8 million, for the same quarter in 2002. Second quarter 2002 net income per diluted share, included $0.01 per share from a net gain on the sale of other assets. Operating revenues grew nine percent in the second quarter to $83.4 million, versus $76.6 million for the same period in 2002 in spite of unfavorable weather throughout the quarter in PSC's primary service areas. Operating revenues in the quarter increased due to rate relief as well as a larger customer base from acquisitions in the various states in which the company operates. "I am pleased with our performance in spite of the fact that we have experienced an unusually cool and wet spring," said Nicholas DeBenedictis, PSC Chairman and President. "May and June traditionally represent the beginning of our heavy demand period. However, during the second quarter, several of our key service areas experienced rainfall more than 100 percent above normal precipitation levels combined with cool, cloudy weather. Poor weather has historically had a five to 10 percent impact on the company's quarterly earnings per share. However, with the addition of the AquaSource states, we gain greater geographic diversity to help mitigate the impact of regional weather anomalies on the company's performance. " The PSC efficiency ratio, or measure of operating and maintenance expenses to revenue, measured 37.2 percent for the second quarter, down from 37.7 percent for the same period in 2002. Year to date 2003, the efficiency ratio was 37.6 percent, also slightly improved from the company's ratio for the first six months of 2002 of 37.9 percent, due to continuing expense management within PSC's operations. "Even though some expenses, such as pension and insurance costs, were up over last year, our management team continues to do an effective job of mitigating increases in controllable expenses to maintain our industry-leading efficiency ratio," explained DeBenedictis.

PSC closed the second largest acquisition in the company's history on July 31, 2003. The acquisition of the investor-owned water and wastewater systems of AquaSource, Inc.--a subsidiary of DQE (NYSE:DQE)--was capitalized at a lower cost of debt than originally expected (4.87 percent), and for a lower-than-expected purchase price ($195 million compared to the initial target of $205 million plus working capital), which will help make the transaction immediately accretive to earnings. Based upon specific performance measures, including revenue, rate base, customer connections, and working capital the final purchase price might be further reduced to a price lower than the stated $195 million. Synergies have been identified and will be acted upon quickly to improve current AquaSource operating efficiencies. Redundant AquaSource overhead functions have been folded into PSC, enabling cost reduction. PSC announced in May 2003 that it had reached an agreement to sell the Connecticut and New York operations of AquaSource, Inc. The strategic decision to quickly prune the Connecticut and New York operations is consistent with PSC's desire to focus on growth of its regulated operations in planned growth markets for the company. The regulated operations of Connecticut and New York represent approximately two percent of the AquaSource customers being acquired. "PSC will continue to seek profitability through a combination of accretive acquisitions in all of the states where we operate, and the strategic pruning of current operations that do not meet our desired profile of a promising growth rate and economies of scale. Any asset sales will then be reinvested in our faster growing franchise areas," said DeBenedictis. On the heels of the AquaSource acquisition, the PSC Board also announced that in October, the company will change its name to Aqua America, Inc. to reflect its position as the largest investor-owned water utility based in the U.S. The company will also change the names of each of its subsidiaries. DeBenedictis said that PSC's expansive customer growth (more than 300 percent in the past 10 years) from a regional company in Pennsylvania to a national company weighed heavily in the decision to change the company's name. The PSC Directors also authorized a 7.1 percent cash dividend increase above the September 1, 2003 quarterly cash dividend payment and also approved for the fifth time in seven years a stock split for 2003, to be effected in the form of a 25 percent stock distribution. Both the increased dividend and stock distribution will be paid December 1, 2003 to shareholders of record on November 14, 2003. Additionally, the Board declared the regular $.14 per share quarterly common stock cash dividend to be paid on September 1, 2003 to shareholders of record on August 15, 2003. Beginning with the December 1, 2003 payment, PSC's quarterly dividend will increase to $.15 per share from $.14 per share ($.60 per share versus $.56 on an

annualized basis) on the pre-split shares. The new quarterly cash dividend rate will be $.12 per share on the increased number of shares resulting from the stock distribution or $.48 per share annualized.
