A pipeline project designed to provide clean, accessible water to residents living in eastern Coachella Valley has been completed, Coachella Valley Water District officials announced today.    The Avenue 66 Transmission project, also known as the Saint Anthony Mobile Home Park Water Consolidation project, involved the installation of more than 26,000 linear feet of water pipes along Avenue 66. The project connects to three mobile home parks — Saint Anthony, Seferino Huerta and Manuela Garcia — and will supply water to the communities of Mecca and North Shore. ”Access to safe, affordable water and sewer services brings additional benefits, including new housing opportunities and economic growth,” CVWD Board Vice President Castulo Estrada said in a statement. Numerous eastern Coachella Valley residents previously received water from failing or at-risk private water systems and unreliable sanitation systems, district officials said.
