Advanced Water Treatment

Advanced water treatment and water reuse (AWT) is a new water supply source, which increases water use efficiency and water supply currently unused or underused sources. Water reuse and desalination may be the only ways to create “new” water supplies to meet these needs—and to fulfill the U.S. Department of the Interior’s (Interior) strategy goals and Reclamation’s mission.

Thus, AWT enables Reclamation to partner with water users throughout the West to expand the supply of water to meet growing needs. AWT is not an exclusive program, but cuts across Reclamation as we have many programs, projects, and expertise that incorporate AWT. Each of the programs use the findings of the research and encourages stakeholders to apply AWT rather than conventional treatment when appropriate. There are also a number of Reclamation projects incorporating AWT research to solve problems that have not been solved before and also have implications beyond the project, e.g. the Water Quality Improvement Center at the Yuma Desalting Plant and the San Joaquin Valley Drainage Demonstration Facility.

Reclamation's AWT research investments support a continuum of activities beginning with basic research discoveries leading to lab, pilot, and demonstration-scale testing to show technical and economic feasibility.


Programs and Projects

Reclamation’s AWT activities span applied research, pilot, demonstration, appraisal, feasibility, design, construction, opperation and maintenance, and outreach and technology transfer. AWT uses seawater, brackish water, and wastewater.

Research Programs

WaterSMART The U.S. Department of the Interior's WaterSMART (Sustain and Manage America's Resources for Tomorrow) program works for efficient use of water, integrating water and energy policies to support the sustainable use of all natural ersources, and coordinating the waer conservation activities of various DOI bureaus and offices. Reclamation plays a key role as the Department's main water agency.
