Seawater Desalination

Menachem Elimelech of Yale University speaks on "Seawater Desalination" at the 2012 NWRI Clarke Prize Conference on "Research and Innovations in Urban Water Sustainability." The conference was held by NWRI in November 2012. Bruce Rittmann of Arizona State University provides an introduction. Watch the video on YouTube.

Desalination & Recycling: New Century, New Sources

In 1993, NWRI produced the "Water from Water" video series. "Desalinatino & Recycling: New Century, New Sources" is the first video program from the seires. The video points out that by using desalination to remove salts, minerals, and other contaminants, inland water supplies can be better used. Watch the video on YouTube.

Seawater Desalination: Opportunities and Challenges

Metropolitan Water District of Southern California, 2003


Desalination is rapidly becoming a viable water-supply option and is considered by many as the “best available technology” for delivering a high-quality, reliable, and sustainable product. The real value of the product water is not necessarily associated with its price or cost, but what it does to enhance the environment, economy, and quality of life of the general population. Nevertheless, a host of challenges remain to be addressed if Southern California water utilities are to optimize desalination as a viable option as a water source.


This workshop report documents the results of the efforts of 31 participants attending a Nominal Group Technique workshop who provided their expertise to answer the question: What are the most critical issues that water utilities will face when planning and implementing seawater desalination projects to supplement drinking-water supplies? One of the many issues discussed was recognizing the value of drought-proofing water sources.
