Exhibit 99.1
                       SJW CORP. (NYSE: SJW) ANNOUNCES
                       THIRD QUARTER FINANCIAL RESULTS

     Board Declares Quarterly Dividend on Common Stock

     SAN JOSE, CA, October 25, 2007 - SJW Corp. (NYSE:  SJW) today reported
net income of $8,011,000 for the quarter ended September 30, 2007, or diluted
earnings per common share of $0.43, compared to $8,858,000 or $0.48 per share
for the same quarter in 2006.

     Operating revenue for the third quarter was $64,847,000 versus $63,119,000
for the same period in 2006, representing an increase of $1,728,000.  The
increased revenue was due to $3,157,000 of cumulative rate increases, $260,000
from new connections, and $357,000 from other sources, partially offset by a
$2,046,000 decrease in revenue due to lower customer usage.

     Total water production costs for the third quarter of 2007, consisting
of purchased water, energy costs and groundwater extraction charges increased
$3,042,000.  Of this increase in production costs, $2,029,000 was from
additional purchased water due to decreased surface water supply and $2,231,000
was due to higher per unit costs for groundwater extraction, purchased water
and energy.  These increased costs were partially offset by a $1,218,000
decrease due to lower customer usage.

     Nonwater production cost increases include increased depreciation expense
of $182,000 due to higher investment in plant and $139,000 additional
maintenance expense compared to the third quarter of 2006.  Administrative
and general expense, along with taxes other than income and other expenses
decreased $24,000.  Income tax expense decreased by $941,000 to $5,178,000
in the third quarter of 2007 versus $6,119,000 in the third quarter of 2006.

     Year-to-date diluted earnings per common share were $0.84 compared to
$1.05 for the same period in 2006.  The decrease in year-to-date earnings was
primarily due to the increase in water production costs which is attributable
to the lack of surface water supply.  There was no impact from the sale of
nonutility property in the first nine months of 2007 versus an $.08 gain from
the sale of nonutility property for the same period of 2006.

     Operating revenue for the first nine months of the year increased
$14,265,000 due to cumulative rate increases of $7,723,000, increased
customer usage of $2,912,000, new customers of $2,711,000 and $919,000
from other sources.

     Year-to-date water production costs increased by $14,560,000 which
was primarily attributable to $7,378,000 in water purchases necessitated
by decreases in surface water supply, $3,832,000 due to higher customer
demand and $3,350,000 due to higher per unit costs for groundwater
extraction, purchased water and energy.  Nonwater production costs
increased $3,463,000, attributable to an increase of $1,298,000 in
maintenance expenses, an increase of $991,000 in depreciation expense,
 an increase of $960,000 in administrative and general costs, and an
increase of $214,000 in taxes other than income and other expenses.
Year-to-date income tax expense decreased $2,139,000 to $10,419,000
from $12,558,000 in 2006.

     Other comprehensive income of $642,000, net of tax, in the third
quarter of 2007 and other comprehensive loss of $1,247,000, net of tax,
year-to-date, was primarily due to changes in the market value of
SJW Corp.'s investment in California Water Service Group.

     The Directors of SJW Corp. today declared a quarterly dividend on
common stock of $0.15125 per share.  The dividend is payable on
December 1, 2007 to shareholders of record on November 5, 2007.
