    SJW CORP. ANNOUNCES APPROVAL BY CPUC OF INCREASE IN RATES

     SAN JOSE, CA, August 24, 2004, SJW Corp. (AMEX:SJW)
announced that on August 19, 2004, San Jose Water Company
(SJWC), its wholly owned subsidiary, received approval in its
General Rate Case from the California Public Utilities Commission
(CPUC) to increase rates by $11.8 million or 8% in 2004; by
$4.3 million or 2.7% in 2005 and by $4.2 million or 2.6% in 2006.
The rate increases reflect a return on equity (ROE) of 9.90% and
a return on rate base (ROR) of 8.86%, which is within the range
of returns currently authorized by the Commission for California
Class A water utilities.

     In January 2004, the CPUC authorized SJWC an interim rate
increase of 2% pending CPUC consideration of SJWC's General Rate
Case application.  This month's decision permits SJWC to recover
the difference between the interim rates authorized in January
2004 and the new rates set forth above.
