Program objective
Desalination and Water Purification Research (DWPR) Program aims to increase water supplies by reducing the costs, energy requirements, and other barriers to adoption of treating impaired water for beneficial uses. The DWPR Program works with Reclamation researchers and partners to develop innovative, cost-effective, and technologically efficient ways to desalinate and treat water. DWPR funding plays a critical role in iterating an idea from the lab to a real-world demonstration, yielding products that serve the water treatment community and attract commercialization interest. Of particular interest is research that has a national significance—where the issues are of large-scale concern and the benefits accrue to a large sector of the public.
