Exhibit 99.1

           SJW CORP. (NYSE:SJW) ANNOUNCES 2008 ANNUAL AND FOURTH QUARTER
                               FINANCIAL RESULTS

     SAN JOSE, CA, February 25, 2009 - SJW Corp. (NYSE:SJW) today reported
operating revenue for the year ended December 31, 2008 of $220.3 million
versus $206.6 million for the year ended December 31, 2007, an increase of
$13.7 million.  The increase in revenue was primarily attributable to
cumulative rate increases.

     Net income was $21.4 million for the year ended December 31, 2008,
compared to $19.3 million for the year ended December 31, 2007.  Diluted
earnings per common share for the year ended December 31, 2008 were $1.15,
compared to $1.04 per share in 2007.

     Water production costs for the year ended December 31, 2008 were $90.2
million versus $86.3 million in 2007, an increase of $3.9 million.  Higher
per-unit costs for purchased water and groundwater extraction charges
contributed $6.0 million to the increase.  These higher costs were
significantly offset by $2.1 million in lower spending on purchased water
due to increased surface water supply in 2008 compared to 2007.

     Non-water production costs for the year ended December 31, 2008 were
$84.0 million versus $78.0 million for 2007, an increase of $6.0 million.
This increase was attributable to increases in 2008 of $1.5 million in
maintenance expenses, $1.5 million in other operating expenses, $1.4 million
in administrative and general expenses, $1.2 million in depreciation and
amortization and $486,000 in taxes other than income tax expense.  Income
tax expense increased $649,000 for the year ended December 31, 2008 to $13.2
million from $12.5 million for the year ended December 31, 2007 as a result
of higher pre-tax income.  Total operating expense for the year ended
December 31, 2008 was $187.5 million, compared to total operating expense
of $176.9 million in 2007.

Fourth Quarter Financial Results
- --------------------------------

     Operating revenue for the fourth quarter ended December 31, 2008 was
$49.5 million versus $47.6 million for the same period in 2007, an increase
of $1.9 million.  The increase was attributable to $3.5 million in cumulative
rate increases, partially offset by $1.6 million in lower customer usage.

     Net income was $4.2 million for the fourth quarter ended December 31,
2008, compared to $3.8 million for the same period in 2007.   Diluted
earnings per common share were $0.23 for the quarter ended December 31,
2008, compared to $0.20 per share for the same period in 2007.

     Water production costs for the fourth quarter of 2008 were $20.3
million versus $18.8 million for the same period in 2007, an increase of
$1.5 million.  Higher per-unit costs for purchased water and groundwater
extraction charges contributed $1.4 million to the increase.

     Non-water production costs for the fourth quarter of 2008 were $21.5
million versus $20.1 million for the same period in 2007, an increase of
$1.4 million.  This was attributable to increases of $489,000 in additional
maintenance expense, $361,000 of other operating expenses, $231,000 of taxes
other than income tax expense and $304,000 of other combined expenses.  Income
tax expense decreased $543,000 for the fourth quarter in 2008 to $1.6 million
from $2.1 million for the same period in 2007.  Total operating expense for
the quarter ended December 31, 2008, was $43.4 million compared to $41.1
million in the period ended December 31, 2007.

     Other comprehensive income of $6.1 million and $5.1 million, net of tax,
for the full year and fourth quarter of 2008, 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 26,
2009.  The webcast will be accessible until May 5, 2009.
