Innovative Approaches to Injection Well Design, Construction, Operation and Maintenance–Sharing Over 40 Years of Practical Experience
Presented on Thursday, December 6, 2012
Since 1975, the Orange County Water District (Orange County, CA) has been operating a seawater intrusion barrier comprised of 102 injection wells through which 30 million gallons per day of recycled wastewater is transferred into a coastal aquifer system. Through the decades many construction and operational challenges have been met, leading to innovative injection well construction designs, operational theories, and redevelopment techniques. This discussion will explore these challenges and the unique approaches employed to maintain a highly effective injection wellfield. Attendees will learn about the evolution of injection well construction and operation theory and various conventional and unconventional redevelopment techniques used to maintain injection well efficiencies.
