Santa Margarita Water District is presenting at the 2018 WEFTEC Conference in New Orleans, Louisiana on October 2, 2018 at 4:30 p.m. This presentation will discuss the award-winning project that led to California's first recycled water recreational lake, and how the team designed, constructed and delivered highly purified wastewater in less than 9 months. Don Bunts, deputy general manager, and Tricia Butler, chief engineer, will also share successes and lessons learned from the project.
Constructed in 1976 and first filled with drinking water in 1978, Lake Mission Viejo is an iconic feature of southern Orange County, California. The lake holds 1.2 billion gallons of water and requires 114 million gallons every year to keep it filled due to evaporative loses. Today, recycled water is used instead of drinking water for supplemental lake refill, making it the first swimming lake in California to do so.
The lake is located in Mission Viejo, California and is owned and operated by the Lake Mission Viejo Association which is comprised of over 75,000 members. The lake is used for swimming, boating, fishing, fire suppression and other water-related recreational activities.
The facility takes already highly-treated recycled water (title 22) and treats it further in a process that includes advanced filtration, reverse osmosis and ultraviolet light. Santa Margarita Water District owns and operates the facility located across the street from Lake Mission Viejo.
WEFTEC® is recognized as the world’s largest annual water quality technical conference and exhibition, providing extensive educational opportunities and unparalleled access to the field’s most cutting-edge technologies and services. The 2018 conference will be held in New Orleans, Louisiana from September 29- October 3.
