Exhibit 99.1

SouthWest Water Company Delays Filing First Quarter 2009 Form 10-Q

Provides Update on Restatement Process

LOS ANGELES--(BUSINESS WIRE)--May 11, 2009--SouthWest Water Company (NASDAQ:SWWC), a leading provider of water, wastewater and public works services, today said it will file a Form 12b-25 with the Securities and Exchange Commission (SEC) indicating that it will not be able to file its quarterly report on Form 10-Q for the period ending March 31, 2009 by May 18, 2009, the extended due date of the filing.

The delay in filing 2009 first quarter results is due to the previously announced restatement of prior period financial results after management discovered certain errors. The company expects to file its first quarter 2009 results as soon as practical after it completes the restatement of prior period statements and files its Form 10-K for the year ended December 31, 2008 and Form 10Q for the quarter ended September 30, 2008.

Separately, SouthWest Water noted that Nasdaq Staff had previously granted an extension until May 11, 2009 for the company to regain compliance by filing all of its delinquent filings. As a result of missing that date, the company expects to receive notice from Nasdaq of the commencement of delisting procedures and intends to follow the Nasdaq established process of requesting a hearing with Nasdaq’s Listing Panel to ask for a further extension.
