About the company
Roca Water, Inc., a woman-owned small business based in Alameda, California, is a manufacturer and developer of electrochemical water treatment technologies that operates as a prime recipient of federal research grants focused on water reuse, desalination, and nutrient recovery from wastewater. The company has received three federal research awards totaling $5 million across three distinct agencies over the past two years, with 100% operating as a prime grant recipient and zero subcontract involvement.
Roca's federal footprint comprises grants from three agencies serving distinct water and energy markets. The Advanced Research Projects Agency (ARPA-E) awarded a $3.7 million cooperative agreement on June 8, 2026, running through June 7, 2029, to develop and commercialize electrochemical technologies for selective ion recovery from wastewater, specifically optimizing ammonium recovery electrodes and discovering magnesium-selective electrodes for dual-ion recovery systems integrated into a market-ready prototype in Alameda. The company received a $175 thousand Phase I award under the USDA National Institute of Food and Agriculture Small Business Innovation Research Program (CFDA 10.212) on August 15, 2025, concluding April 14, 2027, to develop a membrane-free electrochemical salinity reduction system for agricultural irrigation water, with projected treatment cost of $450 per acre-foot. Roca also holds a National Science Foundation cooperative agreement issued April 1, 2024, completing September 30, 2026, for an SBIR Phase II project developing a desalination battery technology using ion-specific electrodes to simultaneously desalt and recover energy from saline feedwater. Two of the three awards face ultimate completion within the next twenty-four months and therefore represent recompete risk for the vendor. Roca's technology portfolio centers on electrochemical selectivity for nutrient and mineral recovery, membrane-free desalination, and brine waste elimination, positioning the company within the federal climate resilience and critical mineral recovery investment space.
