99.1    Press Release issued by SJW Corp., dated July 28,
        2005, announced 2nd Quarter of 2005 Financial Results.


                                                   Exhibit 99.1

       SJW CORP. (AMEX: SJW) ANNOUNCES SECOND QUARTER 2005
                     FINANCIAL RESULTS

          SAN JOSE, CA, July 28, 2005 - SJW Corp. (AMEX:SJW)
diluted earnings per common share for the quarter ended June 30,
2005 were $0.62, compared to $0.53 for the same quarter in 2004.

          Operating revenue for the second quarter was
$44,799,000 versus $45,609,000 for the same period in 2004,
representing a decrease of $810,000 or 2%.  Revenue decreased
$6,580,000 due to lower customer usage, which was offset by
$5,866,000 in cumulative rate increases and $252,000 due to new
customers.  Additionally, parking revenue decreased by $221,000
and other revenues decreased by $127,000.

          Water production costs for the second quarter of 2005
consisting of purchased water, power and pump taxes, decreased
$3,160,000 from the second quarter of 2004.  The decrease in
production costs was primarily attributable to $3,939,000
decrease in usage and $676,000 as a result of greater
availability of surface water.  However, the decrease was
partially offset by increases in the cost of purchased water and
pump tax from Santa Clara Valley Water District of $1,364,000
and other costs of $91,000.

          Quarterly operating expenses for the second quarter of
2005, excluding water production costs and income taxes,
increased $1,028,000 from 2004.  The increase consisted
principally of $554,000 in general and administrative costs,
which includes employee benefits and salaries and wages.
Maintenance expenses increased $163,000 and depreciation expense
increased $156,000 on added utility plant.  Income tax expense
for the second quarter of 2005 was higher than the same period
in 2004 due to increased pre-tax earnings.

          Year-to-date diluted earnings per common share were
$0.91 compared to $0.72 for the same period in 2004.  The
increase in year-to-date earnings was primarily due to
cumulative rate increases that were partially offset by the
impact of lower customer demand.  Year-to-date decrease in water
production costs of $3,311,000 was principally offset by
increases in non-water production costs of $1,852,000 and income
tax expense of $1,272,000.

          Other comprehensive income of $2,706,000 for the
second quarter of 2005 and other comprehensive loss of $71,000
for year-to-date was the result of changes 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 $0.2675
per share.  The dividend is payable on September 1, 2005 to
shareholders of record on August 8, 2005.

          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 San Jose and
nearby communities.
