The York Water Company Added to Russell 3000 Index

YORK, Pa., June 29, 2009 (GLOBE NEWSWIRE) -- The York Water Company
(Nasdaq:YORW) announced today that it has been added to the broad-market Russell
3000(r) Index after the Russell Investment Group published its comprehensive set
of U.S. and global equity indexes on June 29, 2009. The Russell 3000 Index
measures the performance of the largest 3,000 U.S. Companies. Russell indexes
are widely used by investment managers and institutional investors for both
index funds and as benchmarks for passive and active investment strategies.

Each year, the Russell Investment Group rebalances its indexes during its annual
reconstitution. Russell reconstituted its 25 US indexes in order to accurately
weight the 4,000 largest companies in the US stock markets by market
capitalization (of float) and in so doing provide a truer reflection of stock
market activity and performance.

According to York Water President and Chief Executive Officer Jeffrey R. Hines,
"Inclusion in the Russell 3000(r) Index is an indicator of the solid performance
of our Company over the past year and demonstrates our strengthened market
position during these very difficult times." Hines added: "Being included in the
highly-respected Russell 3000(r) Index is a milestone for York Water and
reflects greatly on the fine traditions of this 193-year-old company and our
exceptional customers, shareholders, regulators, and employees."

The York Water Company was founded in 1816 and is the oldest investor-owned
utility in the nation. The business of the Company is to impound, purify and
distribute water. The Company, which is regulated by the Pennsylvania Public
Utility Commission, operates entirely within its franchised territory, which
