About California Water Service Co
California Water Service Co, doing business as California Water Services, is a San Jose-based regulated water utility and subsidiary of California Water Service Group that provides essential water-related services to federal agencies. As a for-profit corporate entity registered in SAM.gov since December 2001, the company has established itself as a qualified federal contractor capable of competing in open bidding processes across multiple government agencies. The company's federal portfolio demonstrates its expertise in delivering water infrastructure services and supporting federal facility operations through both contract and grant mechanisms.
California Water Service Co has secured three prime federal contract awards totaling approximately $304,074 across multiple federal agencies. The most recent award was a $169,801.80 firm fixed-price purchase order from the Defense Contract Management Agency, effective September 1, 2025, through August 31, 2035, for water services supporting operations in Carson, California. The company also received a $94,487.36 purchase order from the U.S. Forest Service dated July 14, 2024, with a completion date of August 21, 2024, for land rental services at multiple forest locations identified as S29 Trout and S326 Borel sites. Additionally, California Water Service Co was awarded a $39,785.00 purchase order from the Department of the Interior's Bureau of Reclamation on August 4, 2023, for water service supporting the MPCO project through August 31, 2028. All three contracts were awarded without set-aside designations, reflecting the company's competitive standing in unrestricted federal procurement processes.
