                           SJW CORP.  ANNOUNCES
                      THIRD QUARTER FINANCIAL RESULTS

             Board Declares Quarterly Dividend on Common Stock

     SAN JOSE, CA, October 28, 2009 - SJW Corp. (NYSE:  SJW) today
reported financial results for the third quarter ended September 30,
2009.  Operating revenue was $69.3 million versus $69.5 million for the
same period in 2008.  The decrease of approximately $200,000 primarily
reflects a decrease of $3.2 million resulting from declining customer
water usage, as well as $881,000 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
$3.5 million and revenue from new customers of $372,000.

     Net income was $8.0 million for the third quarter, compared to $8.3
million in the same period of 2008.  Diluted earnings per share were
$0.43, compared to $0.44 per share for the third quarter in 2008.

     Water production costs for the third quarter of 2009 were $28.6
million versus $30.8 million for the same period in 2008.  The decline in
water production costs of $2.2 million reflects $1.6 million in lower
customer water usage and $1.0 million in savings due to greater surface
water supply, offset by $426,000 in higher per unit costs for purchased
water and groundwater extraction charges.

     Non-water production costs for the third quarter of 2009 were $23.3
million  versus $21.7 million for the same period in 2008, an increase of
$1.6 million.  This was attributable to an increase of $485,000 in
administrative and general expenses primarily related to pension plan
expenses offset by lower transportation and legal and accounting
expenses.   In addition, there were increases of $415,000 in
depreciation and amortization expense, $354,000 in other operating
expense, $254,000 in maintenance expense and $119,000 in taxes other than
income taxes.  Income tax expense increased $219,000 in the third quarter
of 2009 to $5.7 million from $5.5 million in 2008 as a result of a higher
effective tax rate in 2009.

     Year-to-date operating revenue decreased by $3.3 million to $167.5
million from $170.8 million in the first nine months of 2008.  The
decrease was attributable to $10.8 million in lower customer water usage
and $2.0 million in lower revenue from real estate operations, partially
offset by $9.0 million in cumulative rate increases and $497,000 in
revenue from new customers.

     Year-to-date net income was $12.6 million, compared to $17.3 million
in 2008.  Earnings per basic and diluted share respectively were $0.68
and $0.67 in the first nine months of 2009, compared to $0.94 and $0.93
per basic and diluted share, respectively, for the same period in 2008.

     Year-to-date water production costs decreased to $66.1 million from
$69.9 million in 2008.  The $3.8 million decrease was primarily
attributable to lower customer demand of $5.7 million and savings due to
greater surface water supply of $1.2 million, offset by higher per unit
costs for purchased water and groundwater extraction charges of $3.1
million.  Non-water production costs increased $7.0 million to $69.5
million from $62.5 million.  Components of the increase included $3.0
million in administrative and general expenses consisting primarily of
an increase in pension plan expenses, $1.6 million in taxes
other than income taxes, $1.2 million in depreciation expense, $1.1
million in other operating expenses and $70,000 in maintenance expenses.
Income tax expense decreased $2.8 million year-to-date due to lower pre-
tax income.
