ATEC Water Systems, LLC is a leading provider of technologically advanced, cost-effective groundwater filtration systems for community, municipal, agricultural, and industrial use. ATEC’s affordable systems are particularly suited for underserved communities without access to safe drinking water.
Based in Hollister, California, ATEC has produced water-filtration systems since 1982. After pioneering technology to provide high-rate removal of iron and manganese, the company adapted its proprietary treatment method for arsenic, chromium-6, nitrates, and other groundwater contaminants that pose serious health risks in drinking water. ATEC has designed, built, and installed more than 450 specialized filtration systems in 10 U.S. states, Canada and Sri Lanka. The systems can be scaled to serve small communities as well as larger municipalities, with treatment capacity of up to 60 million gallons per day. They require less maintenance than traditional filtration systems, thus lowering operating costs and making them ideally suited to improve the safety of water supplies in small, rural and disadvantaged communities.

Improving reliable access to clean water
ATEC is poised to respond to the challenge of ensuring safe water supplies for families and communities amid the growing threat of groundwater contamination from industrial activity and naturally occurring metals and minerals. This challenge particularly affects rural, small, and community water systems.
Addressing Our Growing Water Treatment Challenge
California
- Nearly one million Californians face potential long-term health risks, including cancer, because they lack safe drinking water, according to a 2022 state audit.
- Residents of socioeconomically disadvantaged communities account for 84% of those at risk from drinking water that exceeded maximum levels of health-harming contaminants, such as arsenic and chromium-6.
- Water systems serving an additional one million Californians are at risk of failing to meet state and federal water-quality standards. Nearly two-thirds of these systems serve disadvantaged communities.
- Of 7,400 public water systems in California, more than 3,000 have two or more water-quality violations.
- A 2019 analysis estimated that six million Californians, or 15% of the population, were served by water systems that had failed to comply with state drinking-water standards at some point since 2012, when California enacted a law declaring access to clean, safe, and affordable water a human right.
- More than 1.3 million Californians use largely unregulated domestic groundwater wells for drinking water. Of 273,000 wells, nearly 78,000 operate in areas at risk of contamination and are disproportionately located in disadvantaged communities.
- Community water systems serving more than 4.1 million Californians reported chromium-6 levels above the new proposed state limit.
