Exhibit 99.1

                        SJW CORP. (NYSE: SJW) ANNOUNCES
                        THIRD QUARTER FINANCIAL RESULTS

Board Declares Quarterly Dividend on Common Stock

      SAN JOSE, CA, October 22, 2008 - SJW Corp. (NYSE:  SJW) today
reported operating revenue for the third quarter ended September 30,
2008 of $69.5 million versus $64.9 million for the same period in 2007,
representing an increase of $4.7 million.  The increase in revenue was
primarily attributable to cumulative rate increases.

      Net income was $8.3 million for the quarter compared to $8.0 million
for the same quarter in 2007.  Diluted earnings per common share were
$0.44, compared to $0.43 per share for the same quarter in 2007.

      Water production costs for the third quarter of 2008 were $30.8
million versus $29.6 million for the same period in 2007, an increase of
$1.3 million.  Higher per-unit costs for purchased water and groundwater
extraction charges contributed $2.2 million to the increase.  These
expenses were significantly offset by lower spending on purchased water
due to increased surface water supply compared to a year ago.

      Non-water production costs for the third quarter of 2008 were $21.7
million versus $19.4 million for the same period in 2007, an increase of
$2.3 million.  This was attributable to increases of $747,000 in
administrative and general expenses, $619,000 in other operating expenses,
$477,000 in maintenance expenses, $298,000 in depreciation and amortization
and $180,000 in property and other non-income taxes.  Income tax expense
increased $338,000 in the third quarter to $5.5 million in 2008 from
$5.2 million in 2007 as a result of higher pre-tax income.

      Year-to-date operating revenue increased by $11.8 million to $170.8
million from $159.0 million in the first nine months of 2007.  The increase
was attributable to $10.4 million in cumulative rate increases, $831,000
in increased usage, $432,000 from new customers, and $144,000 from other
sources.

      Year-to-date net income was $17.3 million, compared to $15.5 million
in 2007.  Diluted earnings per common share were $0.93 in the first nine
months of 2008, compared to $0.84 per share for the same period in 2007.

      Year-to-date water production costs increased to $69.9 million
from $67.5 million in 2007.  The increase was primarily attributable to
$4.7 million in higher costs for groundwater extraction and purchased
water, partially offset by $1.9 million saved due to increased surface
water supply. Non-water production costs increased $4.6 million to $62.5
million from $57.9 million.  Components of the increase included $1.2
million in administrative and general expenses, $1.1 million in other
operating expenses, $1.0 million in maintenance expenses, $1.0 million
in depreciation and amortization expense and $255,000 in property and
other non-income taxes. Income tax expense increased $1.2 million
year-to-date due to higher pre-tax income.

common stock of $0.16125 per share.  The dividend is payable on December
1, 2008 to shareholders of record on November 3, 2008.
