The South Coast Water District is forging ahead as the lone agency intent on making a desalination facility in Dana Point a reality after more than 10 years of discussion.

The district, which serves customers in South Laguna, Dana Point, San Juan Capistrano and San Clemente, wants to build a treatment plant on 30 acres of property it owns near San Juan Creek in hopes of eventually producing 15 million gallons of potable water a day.
