CAL WATER FINALIZES HOLDING COMPANY FORMATION

San Jose, CA - After receiving final regulatory approval from the California
Public Utilities Commission, directors of California Water Service Company
today gave their final approval to adopt the holding company structure which
was approved by shareholders at their annual meeting in April.  The new holding
company, which is expected to be activated at the close of business on
December 31, 1997, will be known as California Water Service Group.

"In conjunction with the holding company formation, California Water Service 
Company common stock shareholders of record on December 31, 1997, will 
automatically become common stock shareholders of the new holding company on a
two-for-one basis, effectively splitting the common stock," said Robert W. Foy,
Chairman of the Board.  "The New York Stock Exchange trading symbol for
California Water Service Group common stock will be "CWT", the same symbol
under which California Water Service Company is traded," Foy said.

After December 31, 1997, when the holding company structure becomes 
effective, existing common stock certificates of California Water Service
Company will represent the same number of California Water Service Group
common stock shares.  To complete the effective stock split, on
January 23, 1998, new California Water Service Group common stock certificates
equal to the number of shares held by shareholders on December 31, 1997, will
be mailed to common stock owners.

Preferred shareholders of California Water Service Company will become 
preferred shareholders of the new holding company on a one-for-one basis,
however, their voting rights will be doubled to retain their relative voting
power. 

As previously announced, a new Dividend Reinvestment and Stock Purchase 
Plan will be introduced by California Water Service Group.  Shareholders
enrolled in the existing California Water Service Company Dividend Reinvestment
Plan will automatically be enrolled in the new California Water Service Group
Dividend Reinvestment and Stock Purchase Plan when it becomes effective.  The
existing plan will be terminated when the new plan is activated, which is
expected to occur in late February 1998, after payment of the first quarter
dividend.  Until then, the existing plan will be continued on the same terms
and conditions, except that it will apply to California Water Service Group
common stock after December 31, 1997.  Details of the new plan will be mailed
with the first quarter 1998 dividend.

"Formation of the holding company is not anticipated to affect the utility 
operations or work force of California Water Service Company.  The utility
company will continue to be known to customers and employees as Cal Water and
will be dedicated to providing the same excellent customer service as it has
in the past," Foy said.

"As we approach the new century, we believe the holding company will provide 
the flexibility necessary to operate effectively with continued growth in a
more competitive and changing water utility industry," Foy said.

Cal Water, the largest investor-owned water utility in California and the third
largest in the country, has provided high-quality domestic water service since
1926.  Cal Water's 21 operating districts serve approximately 1.5 million
people in 57 California communities. Additional information can be found at
