In an effort to solve water shortage issues in the U.S. state of California, Governor Gavin Newsom has ordered key state agencies to develop a blueprint for meeting California’s 21st century water needs, to ensure safe and resilient water supplies, flood protection and healthy waterways for the state’s communities, economy and environment.

Two solutions in which composites play a significant role are wastewater purification (which was featured in CW‘s January 2020 feature “Composites help take the waste out of wastewater”) and, the focus of this report, seawater reverse osmosis (SWRO) desalination.

The problem in California is easy to understand, but difficult to solve: The original configuration of rivers, streams, lakes, bays and underground water (aquifers) in California has been reconfigured so extensively over the years to accommodate a growing population and conflicting interests that these resources cannot be relied upon to meet future water needs — even the near future.
