CAL WATER COMPLETES DELAWARE REINCORPORATION

SAN JOSE, CA (November 23, 1999) - California Water Service Group (NYSE -
CWT) announced that today it had completed the process to reincorporate
Group as a Delaware corporation.
The reincorporation, which was approved by shareholders at their annual
meeting in April, has a number of advantages for Group: the Delaware
legislature is responsive to business needs and acts quickly to enact
relevant new laws; Delaware has the most extensive case law on corporate
issues of any state, thereby providing corporations with more certainty
about the application of laws in specific circumstances; state courts that
specialize in corporate law have developed an expertise in dealing with
corporate issues; and the state has developed a sharper definition of
director responsibilities so that boards may act with greater certainty on
issues affecting shareholders.
California Water Service Group is the parent company of California Water
Service Company, CWS Utility Services and Washington Water Service Company
serving approximately 1.5 million people in 60 California and Washington
communities. Group is the largest investor owned water utility in the
western states.
Group's common stock trades on the New York Stock Exchange under
the symbol CWT.  More information may be found at www.calwater.com.
