Exhibit 99.1

              SJW CORP. ANNOUNCES 2007 ANNUAL AND FOURTH QUARTER
                              FINANCIAL RESULTS


     SAN JOSE, CA, February 20, 2008 - SJW Corp. (NYSE: SJW) today reported
operating revenue of $206,601,000 for the year ended December 31, 2007,
compared to operating revenue of $189,238,000 in 2006. Operating revenue for
2007 increased $17,363,000 over 2006 due to cumulative rate increases of
$10,409,000, revenue from new customers of $3,002,000, increased customer
usage of $2,784,000 and revenue from other sources of $1,168,000.

     Net income was $19,323,000 for the year ended December 31, 2007.
Diluted earnings per common share for the year ended December 31, 2007 were
$1.04 compared to $2.08 in 2006.  The change in diluted earnings was
primarily due to a $0.89 per share gain in 2006 from the sale of real estate
assets.  The remainder of the change was due to increased water production
costs in 2007.

     Operating expenses for the year ended December 31, 2007 were
$176,848,000 compared to $157,685,000 in 2006.  The increase of $19,163,000
in operating expenses in 2007 versus 2006 was primarily attributable to
increases in water production costs.

     Water production costs for the year ended December 31, 2007 were
$86,269,000 compared to $68,803,000 in 2006.  The increase of $17,466,000 in
2007 versus 2006 was attributable to $8,685,000 in additional water
purchases necessitated by decreases in surface water supplies available in
the California service area, $4,814,000 due to higher per unit costs for
purchased water, groundwater extraction and energy and $3,967,000 due to
higher customer demand, including new customers added in 2007.

     Nonwater production costs were $78,030,000 for the year ended December
31, 2007.  The increase of $4,446,000 in 2007 versus 2006 was attributable
to an increase of $1,555,000 in depreciation expense, an increase of
$1,439,000 in maintenance expenses primarily due to a larger amount of leak
repairs, an increase of $1,226,000 in administrative and general costs
primarily due to higher benefit costs and increases in salaries and an
increase of $226,000 in other combined expenses.  Income tax expense for the
year ended December 31, 2007 decreased $2,749,000 from $15,298,000 in 2006
to $12,549,000 in 2007.

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

     Operating revenue for the fourth quarter ending December 31, 2007 was
$47,602,000 versus $44,504,000 in 2006, an increase of $3,098,000.  The
increase in operating revenue was due to $2,686,000 of cumulative rate
increases, $291,000 from new connections and $249,000 from other sources,
partially offset by a $128,000 decrease in operating revenue due to lower
customer usage.

     Net income was $3,784,000 and diluted earnings per common share were
$0.20 for the quarter ended December 31, 2007, compared to $1.03 per share
in 2006.  On December 15, 2006, SJW Corp. sold nonutility investment
properties located in San Jose, California, for an aggregate purchase price
of $32,500,000, which resulted in recognizing a gain on the sale of real
estate investments of $14,820,000, net of taxes of $10,192,000, or $0.81 per
share.  There was no corresponding sale of real estate investments in the
fourth quarter of 2007.

     Water production costs for the fourth quarter of 2007 were $18,812,000
compared to $15,906,000 in 2006.  The $2,906,000 difference consisted of
increases of $1,464,000 due to higher per unit cost for groundwater
extraction, purchased water and energy, $1,307,000 in additional purchased
water due to decreased surface water supply in 2007 and $135,000 due to
higher customer usage.

     Nonwater production costs in the fourth quarter of 2007 were
$20,107,000 compared to $19,124,000 in 2006, due to increased depreciation
expense of $564,000 resulting from higher investment in plant, $266,000 of
additional administrative and general expense, $141,000 of additional
maintenance expense and $12,000 of other combined expenses.  Income tax
expense decreased $610,000 from $2,740,000 in the fourth quarter of 2006 to
$2,130,000 in the fourth quarter of 2007.

     Other comprehensive loss of $2,201,000 and $954,000, net of tax, in the
full year and fourth quarter of 2007, 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
home page, www.sjwater.com, at 10:00 A.M. Pacific time on Thursday, February 21,
2008.  The webcast will be accessible until April 29, 2008.
