Advanced Water Treatment Operator Certification


AWT Operator certification

Advanced Water Treatment Operator™

AWT Operators (AWTO™) protect public health by ensuring a supply of safe and high-quality drinking water from advanced water reuse facilities.

AWTOs understand advanced processes and the impact of feed water quality on production and finished water quality. They operate, monitor, and maintain AWT processes, such as membrane systems and advanced oxidation.

At the higher grade levels, AWTOs have an advanced understanding of technologies and the regulations pertinent to the end uses of treated water; such as recycled water, potable water, and potable water reuse.

AWTOs at the supervisor and management level maintain regular communication with regulatory agencies and ensure permit compliance. They are responsible for preparing and submitting regulatory reports. They are also responsible for ensuring safety planning, procedures and team safety meetings are completed to keep team members safe.

There are currently six Advanced Water Treatment Facilities in California producing pure water for groundwater recharge. Several more facilities are in the design and permitting process and will come online over the next five years.
