Exhibit 99.1

            SJW CORP. ANNOUNCES 2009 ANNUAL AND FOURTH QUARTER
                            FINANCIAL RESULTS

     SAN JOSE, CA, February 24, 2010 - SJW Corp. (NYSE: SJW) today
reported operating revenue for the year ended December 31, 2009 of
$216.1 million versus $220.3 million for the year ended December 31,
2008, a decrease of $4.2 million.  The decrease in revenue was primarily
attributable to a decline in customer water usage of $12.8 million, as
well as $2.7 million in lower revenue from real estate operations due to
a tenant vacancy in the real estate portfolio.  The revenue decreases
were partially offset by cumulative rate increases of $10.7 million and
revenue from new customers of $0.6 million.

     Net income was $15.2 million for the year ended December 31, 2009,
compared to $21.5 million for the year ended December 31, 2008.  Diluted
earnings per common share for the year ended December 31, 2009 were
$0.81, compared to $1.15 per share in 2008.

     Water production costs for the year ended December 31, 2009 were
$83.5 million versus $90.2 million in 2008, a decrease of $6.7 million.
The decline in water production costs is primarily attributable to $7.3
million in lower customer water usage and $2.6 million in savings due to
greater surface water supply, offset by $3.2 million in higher per unit
costs paid for purchased water and groundwater extraction charges.

     Operating expenses, excluding water production costs and income
taxes, for the year ended December 31, 2009 were $92.9 million versus
$84.0 million for 2008, an increase of $8.9 million.  This increase was
primarily attributable to increases in 2009 of $4.0 million in
administrative and general expenses largely related to pension plan
expenses, $1.8 million in taxes other than income tax expense, $1.6
million in depreciation and amortization and $1.5 million in other
operating expenses.  Income tax expense decreased $2.9 million for the
year ended December 31, 2009 to $10.3 million from $13.2 million for the
year ended December 31, 2008 as a result of lower pre-tax income.  Total
operating expense, including water production costs, for the year ended
December 31, 2009 was $186.7 million, compared to total operating
expense of $187.5 million in 2008.

Fourth Quarter Financial Results
- --------------------------------
     Operating revenue for the fourth quarter ended December 31, 2009 was
$48.6 million versus $49.5 million for the same period in 2008, a
decrease of $900,000.  The decrease was attributable to $2.0 million in
lower customer water usage and $660,000 in lower revenue from real
estate operations, partially offset by $1.6 million in cumulative rate
increases and $79,000 in revenue from new customers.

     Net income was $2.6 million for the fourth quarter ended December
31, 2009, compared to $4.2 million for the same period in 2008.  Diluted
earnings per common share were $0.14 for the quarter ended December 31,
2009, compared to $0.23 per share for the same period in 2008.

     Water production costs for the fourth quarter of 2009 were $17.4
million versus $20.3 million for the same period in 2008, a decrease of
$2.9 million.  Lower customer water usage and savings due to greater
surface water supply contributed to the decrease.

     Operating expenses, excluding water production costs and income
taxes, for the fourth quarter of 2009 were $23.4 million versus $21.5
million for the same period in 2008, an increase of $1.9 million.  This
was attributable to increases of $945,000 in administrative and general
expenses due to pension plan expenses, $443,000 in depreciation and
amortization, $345,000 in other operating expenses and $186,000 in taxes
other than income tax expense.  Income tax expense decreased $118,000
for the fourth quarter in 2009 to $1.5 million from $1.6 million for the
same period in 2008 due to lower pre-tax income.  Total operating
expense for the quarter ended December 31, 2009, was $42.3 million
compared to $43.4 million in the period ended December 31, 2008.

     Other comprehensive loss of $6.2 million and $1.4 million, net of
tax, for the full year and fourth quarter of 2009, respectively, was
primarily due to changes in the market value of SJW Corp.'s investment in
California Water Service Group.

     SJW Corp. management will discuss the annual and fourth quarter
results in a webcast presentation available to interested parties from
the Company's website, www.sjwater.com, at 10:00 A.M. Pacific Time on
Thursday, February 25, 2010.  The webcast will be accessible until
