The Drinking Water Treatment Partnership Project was established in the spring of 2013 as a means of addressing the need for clean drinking water in low-income mobile home parks located throughout the Eastern Coachella Valley. Through the various contributions of the involved partners, this project has provided, and continues to provide, installation of water treatment systems (reverse osmosis units) to underserved mobile home communities that have high levels of arsenic and/or fluoride in their raw water sources.
