ATEC Water Systems
About
ATEC Water Systems, LLC, operating as a Cadiz Solution, has designed and manufactured vertical filtration systems for contaminated groundwater treatment from its Hollister, California facility for over 30 years. The company has completed more than 450 installations across the western United States, Canada, and Sri Lanka, specializing in affordable, scalable drinking water treatment for communities ranging from small rural systems to large municipal utilities. ATEC's signature vertical filtration technology costs approximately one-third of typical horizontal filtration systems while featuring automatic, unattended backwash cycles that require no additional infrastructure. Each system is custom-built at ATEC's in-house manufacturing facility, with capacities spanning from 10 GPM for small community water systems up to 60 MGD for large public utilities. The company holds several pioneering achievements: the first municipal iron and manganese removal system using dioxide media, the first U.S. installation for arsenic removal using granular ferric hydroxide, and a proprietary chromium-6 removal process that cut treatment costs by half. Current treatment capabilities cover iron and manganese removal (accounting for 90% of systems to date), arsenic removal, chromium-6 removal, biological ammonia removal, PFAS treatment, boron removal, and nitrate removal. ATEC provides full turnkey services including pilot testing, custom engineering, in-house manufacturing, onsite installation, 24/7 remote monitoring, and maintenance requiring as few as four visits per year.
