               SJW CORP. (NYSE: SJW) ANNOUNCES THIRD QUARTER 2006
                             FINANCIAL RESULTS

    SAN JOSE, CA, October 26, 2006 - SJW Corp. (NYSE:SJW) diluted earnings per
common share for the quarter ended September 30, 2006 were $0.48, compared to
$0.50 for the same quarter in 2005. The decrease is due to the inclusion of the
net of tax gain on the sale of nonutility property of $1,095,000, or $0.06
per share, in the third quarter of 2005.

    Operating revenue for the third quarter was $63,119,000 versus $58,469,000
for the same period in 2005, representing an increase of $4,650,000 or 8%.
Revenues increased $1,825,000 due to new customers, of which approximately
$1,500,000 is attributable to SJW Corp.'s acquisition of a Texas water system
known as Canyon Lake Water Service Company.  In addition, revenues increased
$1,572,000 in higher customer usage, $1,019,000 in cumulative rate increases
and $234,000 in other revenues.

    Water production costs for the third quarter of 2006 increased $1,836,000
from the third quarter of 2005. The increase in production costs was primarily
attributable to $941,000 increase in the cost of purchased water and pump tax
from Santa Clara Valley Water District, $987,000 increase in usage and new
customers, including purchased water for Canyon Lake Water Service Company and
an increase in other costs of $208,000, partially offset by a decrease of
$300,000 as a result of greater availability of the least expensive source of
water which is surface water.

    Quarterly operating expenses for the third quarter of 2006, excluding water
production costs and income taxes, increased $1,312,000 from 2005. The increase
consisted principally of $321,000 in general and administrative costs,
primarily as a result of the operations of Canyon Lake Water Service Company
included in the third quarter of 2006.  In addition, depreciation expense
increased $466,000 as a result of growth in utility plant, other operating and
maintenance expenses increased $436,000 and taxes other than income taxes
increased $89,000.  Included in the earnings of the third quarter of 2005 was
the net of tax gain on the sale of nonutility property of $1,095,000.  Income
tax expense increased $364,000 for the third quarter in 2006 due to increased
pre-tax earnings.

    Year-to-date diluted earnings per common share were $1.05 compared to $0.96
for the same period in 2005.  The increase in year-to-date earnings was
primarily due to higher customer demand and an increase in new customers, which
is primarily attributable to Canyon Lake Water Service Company.  Year-to-date
operating revenue increased $8,159,000 or 6%, due to new customers of
$2,798,000, higher customer demand of $2,660,000, cumulative rate increases of
$1,989,000 and $712,000 in real estate and other revenues.

    Year-to-date water production costs increased by $1,929,000 and were
primarily attributable to $1,777,000 increase in the cost of purchased water
and pump tax, $1,795,000 increase in usage, and other costs of $287,000,
partially offset by a decrease of $1,930,000 as a result of greater
availability of surface water.  Non-water production costs increased $3,454,000
and were primarily attributable to $776,000 in other expenses, which included
an increase in employees and operating expenses, largely attributable to Canyon
Lake Water Service Company.  In addition, depreciation expense increased
$1,056,000, general and administrative costs increased $771,000, maintenance
costs increased $675,000 and taxes other than income taxes increased $176,000.
Income tax expense increased by $936,000 due to increased pre-tax earnings.

    Other comprehensive income of $772,000 and other comprehensive loss of
$844,000, net of tax, for the third quarter of 2006 and year-to-date,
respectively, were the result of changes in the market value of the investment
in California Water Service Group.

    At its meeting today, the Board of Directors of SJW Corp. declared a
quarterly dividend on common stock of $0.14125 per share.  The dividend is
payable on December 1, 2006 to shareholders of record on November 6, 2006.
