The Doheny Desalination Plant is a 5-million-US-gallon per day (19 Ml) facility proposed by South Coast Water District in Dana Point, California.

The 30-acre site (12 ha) is just north of State Route 1 on east side of San Juan Creek with access off Stonehill Drive.

[2][3] Eastern Municipal Water District (EMWD), in Riverside County, approved a plan to buy paper water rights which involves the two agencies swapping rights on paper.

[4] The subsurface intake (slant) wells at Doheny State Beach will be fully buried beneath the ocean floor to protect marine life.

[5] Brine, the saltwater left over from the desalination process, would be co-mingled with treated wastewater in an existing outfall pipe 2 miles (3.2 km) offshore.
