Exhibit 99.1 SJW CORP. (NYSE: SJW) ANNOUNCES FIRST QUARTER FINANCIAL RESULTS Board Declares Quarterly Dividend on Common Stock SAN JOSE, CA, April 26, 2007 - SJW Corp. (NYSE: SJW) today reported net income of $2.122 million for the quarter ended March 31, 2007, or diluted earnings per common share of $0.11, compared to $4.203 million or $0.23 per share for the same quarter in 2006. During the first quarter of 2006, a sale of nonutility property contributed approximately $1.535 million or $0.08 per share to earnings. Operating revenue for the first quarter was $39,017,000 versus $33,741,000 for the same period in 2006, representing an increase of $5,276,000 or 16%. Approximately $2,284,000 of the total revenue increase was attributable to cumulative rate increases, $1,453,000 came from increased customer demand, $1,365,000 was attributable to new connections, and $174,000 was from other sources. "The first quarter represented another strong revenue period for SJW Corp.," said W. Richard Roth, President and Chief Executive Officer. "Our team is executing well, and we are excited about the progress we are making with Canyon Lake Water Service Company in Texas." "At the same time, during the quarter, we experienced increased production costs due to increased purchased water. Rainfall to date in our watershed in California has been a little less than half of normal levels, and this could mean continued increases in purchased water and groundwater production for the next few quarters." Total water production costs for the first quarter of 2007, consisting of purchased water, energy and groundwater extraction charges, increased $4,455,000, or 15% from the first quarter of 2006. Of this increase in production costs, $2,185,000 was attributable to decreased surface water supply necessitating additional purchased water, $1,923,000 was due to higher customer demand and $347,000 was spent on higher costs for groundwater extraction, higher energy prices and other costs. Total quarterly administrative and general expenses in the first quarter of 2007 increased $699,000 from 2006 due to $370,000 dedicated to operation of the Canyon Lake Water Service Company which was acquired in the second quarter of 2006, $396,000 in increased salaries, benefits and retirement costs, $142,000 in increased worker's compensation costs due to a nonrecurring refund received in the first quarter of 2006, offset by a $209,000 decrease in other costs. In addition, maintenance expenses increased $487,000, depreciation expense increased $423,000, and taxes other than income increased $112,000. Income tax expense decreased $488,000 in the first quarter of 2007 versus the first quarter of 2006. During the quarter, SJW Land Company, a wholly-owned subsidiary of SJW Corp., announced the purchase of real estate located in Knoxville, Tennessee, for an aggregate purchase price of approximately $47,625,000. The purchase was funded from proceeds of a nonutility property sale that occurred in the fourth quarter of 2006, along with borrowed funds of approximately $13,500,000. "The purchase of the office building, distribution facility and adjacent acreage in Knoxville is in line with our goal of owning income- producing properties that provide a return consistent with the return on the entire real estate portfolio," said Mr. Roth. For the three months ended March 31, 2007, other comprehensive loss of $1,350,000, net of tax, was due to a decrease in the market value of the investment in California Water Service Group as of that date. Additionally, the Directors of SJW Corp. today declared a quarterly dividend on common stock of $0.15125 per share. The dividend is payable on June 1, 2007 to shareholders of record on May 7, 2007.
