          SJW CORP. (AMEX: SJW) ANNOUNCES SECOND QUARTER
                         FINANCIAL RESULTS

     SAN JOSE, CA, July 29, 2003 - SJW Corp. (AMEX:SJW) basic
earnings per common share for the quarter ended June 30, 2003
were $1.46, compared to $1.31 for the same quarter in 2002.

     Operating revenue for the second quarter was $37,968,000
versus $38,696,000 for the same period in 2002.  The decrease of
$728,000 was primarily attributable to an 8% weather related
decrease in customer consumption that was partially offset by a
4% rate increase in San Jose Water Company.
     Total water production costs, which consist of purchased
water, power and pump taxes, decreased $3,114,000, or 18% from
the second quarter of 2002.  The decrease was primarily
attributable to an approximate 8%, or $2,120,000, decrease in
customer consumption, and an increase in the availability of less
costly surface water which contributed $1,285,000 to the overall
reduction in water production costs.  Total quarterly operating
expenses, excluding water production costs and income taxes,
increased $1,436,000 or 11% from 2002.  SJW Corp. experienced
increases principally of:  $330,000 in salaries and related
costs, $275,000 in pension costs primarily as a result of the
decline in market value of retirement trust assets, $329,000 in
depreciation expense primarily on added utility plant, $116,000
in legal and professional fees and $356,000 in insurance related
costs.  Income tax expense for the second quarter of 2003 was
higher in comparison to the same period of 2002 due to higher
earnings in 2003.
     Year-to-date earnings per common share were $3.19 compared
to $1.88 for the same period in 2002.  The increase in year-to-
date earnings was mainly due to the sale of a SJW Land Company
property in the first quarter of 2003, which resulted in an
after-tax gain of $3,030,000, or $1.00 per share.  The remaining
increase in operating net income was due to similar reasons as
explained above.
     Other comprehensive income of $1,538,000 and $2,901,000,
respectively, for the three months and six months ended June 30,
2003, was a result of an increase in the market value of the
investment in California Water Service Group.
     At its meeting today, the Board of Directors of SJW Corp.
declared a quarterly dividend on common stock of  $0.7275 per
share.  The dividend is payable on September 1, 2003 to
shareholders of record on August 11, 2003.
     SJW Corp. is a publicly traded holding company headquartered
in San Jose, California.  SJW Corp., through its subsidiary San
Jose Water Company, provides water service to a population of
approximately one million people in the City of  San Jose and
nearby communities.
