LOS ANGELES--(BUSINESS WIRE)--May. 14, 2009-- SouthWest Water Company (NASDAQ:SWWC), a leading provider of water, wastewater and public works services, today said that as expected, it received a Nasdaq Staff Determination letter on May 12, 2009 indicating that the company's common stock is subject to potential delisting as of May 21, 2009. The company is not in compliance with Nasdaq Marketplace Listing Rule 5250(c)(1) due to its failure to timely file its quarterly reports on Form 10-Q for the quarters ended September 30, 2008 and March 31, 2009, as well as its annual report on Form 10K for the year ended December 31, 2008. The delay in filing results is due to the previously announced restatement of prior period financials.

SouthWest Water intends to request a hearing before a Nasdaq Listing Qualifications Panel to review the Staff determination. In its determination letter, Nasdaq informed the company that the hearing request will stay the delisting of the company's common stock for an additional fifteen days, or until June 3, 2009. The company, in its request for a hearing, will also request an additional stay until it is able to file all of its delinquent filings to regain compliance.
