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.
