                          CAL WATER ANNOUNCES INCREASED
                     REVENUES AND EARNINGS FOR 4TH QTR 2003;
                       BOARD INCREASES DIVIDEND TO $.2825

- --------------------------------------------------------------------------------

         SAN JOSE,  CA -  California  Water  Service  Group  (NYSE : CWT)  today
announced  fourth  quarter 2003 net income of $7.0 million,  up 146% over fourth
quarter 2002, and diluted  earnings per share of $0.41, an increase of 116% over
the same period last year.

         Revenue for the quarter increased $8.7 million or 14% to $69.6 million.
Adding to revenue were $6.5 million in rate increases,  $1.8 million in sales to
new customers, and $0.4 million in increased sales to existing customers.

         Operating  expenses were $62.1 million,  an increase of $6.6 million or
12% over the same period last year.  The largest  component  of the increase was
income and other taxes, which rose $3.3 million. Expenses also increased in most
other categories, including purchased water, payroll, benefits, water treatment,
and depreciation.




         Fourth quarter results were bolstered by surplus property sales, as the
company had pretax gains of $3.1 million  compared to $1.0 million in the fourth
quarter of 2002.

Full Year 2003 Results

         2003 net income was $19.4  million,  compared to $19.1 million in 2002,
and diluted earnings per share were $1.21,  compared to $1.25 in 2002.  Earnings
per share  decreased 3% because 1.750 million  additional  shares were issued in
August 2003.

         Revenue for 2003 was $277.1  million,  increasing  $14.0 million or 5%,
due to rate  increases of $12.6  million and $6.0 million in revenues from sales
to new customers.  Partially  offsetting these increases were decreased revenues
of $4.6  million  from  sales to  existing  customers,  primarily  due to higher
rainfall in the first half of 2003.

         Total  operating  expenses  increased by $14.5 million,  or 6%, for the
year. The company incurred higher  wholesaler rates and purchased more water; as
a result, water costs increased by $3.1 million.  Other operating increases were
primarily in payroll and benefit  costs ($5.5 million or 10%),  water  treatment
($1.2 million or 24%), maintenance ($1.1 million or 10%), and depreciation ($2.0
million or 9%).

         Interest  expense  increased due to additional  long-term debt incurred
during  2002 and in the first  quarter  of 2003.  This was  partially  offset by
reduced  interest  expense from  refinancing a portion of our long-term debt and
lower  short-term debt levels due to pay downs made with funds obtained from the
equity offering.

         Pretax gains from surplus  property sales were $4.6 million,  which was
$1.6 million higher than pretax gains in 2002.




         The issuance of  additional  shares in August 2003 raised $43.8 million
of capital,  which  strengthened  the balance sheet. The percentage of equity to
total capitalization  increased from 44% to 47% as of December 31, 2002 and 2003
respectively.

         President and CEO Peter C. Nelson characterized 2003 as a year in which
the company "turned a corner" and finally began to receive  critical rate relief
in late 2003 from the California Public Utilities Commission ("Commission").

         "For some time now, our financial  performance  has been  significantly
impacted  by a lack of  timely  decisions  from the  Commission,  but we are now
seeing the results of fairer regulatory treatment. In 2003, we received approval
for rate increases  that will add an annual $26 million in revenues,  as well as
$9 million in surcharges collected over a 24-month period," Nelson said.

         According  to  Nelson,   because  rate   increases  are  not  collected
retroactively, it takes time to see their full effect.

         "Our fourth quarter  results showed a big  improvement,  as most of the
2003  rate  increases  were in  place  for the  entire  quarter.  With  the rate
increases  and  gains  from  sales of  surplus  properties,  we had a very  good
quarter," he said.

         In January 2004, the Commission approved an additional rate increase of
$4.2 million which became effective in January.

         Pending  applications  to the  Commission  include  general  rate  case
filings and recovery of  "balancing-type  memorandum  accounts," which primarily
reflect  electricity rate increases incurred in 2002. The company cannot predict
the amount or the timing of Commission decisions on pending filings.
