Drinking water treatment, wastewater treatment or water reuse operators working at facilities using advanced water treatment technologies and related control processes may be interested in earning the new, voluntary AWT Operator (AWTO®) Certification.
Why are we developing the AWTO Certification?
- Build public trust in Advanced Water Treatment Operators
- Fulfill the call by the California Urban Water Agencies (CUWA) white paper on AWT Operator certification
- Address the California State Water Board’s Expert Panel findings on Indirect and Direct Potable Reuse barriers, namely answering their recommendation to develop AWT operator certification
- Maximize wastewater reuse and other challenging source waters
The AWT Operator Certification Committee formed three years ago to develop a voluntary certification program as part of the CA-NV AWWA offerings. The California Water Environment Association (CWEA) joined the effort, and together we are building a world-class AWT Operator certification program.
What does an AWT Operator do?
AWT Operators protect public health by ensuring a supply of safe and high-quality drinking water from advanced water reuse facilities.
Our job analysis research found the following responsibilities for each grade level:

When will the exam be ready?
Spring 2019. We are planning to have exams ready for Grades 3-5.
What are the minimum qualifications to take the exam?
All CA and NV drinking water and wastewater treatment operators with a grade 3 or above will start the AWTO certification program at the AWTO Grade 3 level. Operators may progress directly up the AWTO certification independently from their respective state treatment operator certifications.
The following are the proposed qualifications based on the consensus of the subcommittee.
- For a AWTO Grade 3 certification, the minimum qualifications for entry to the exam is a California or Nevada Grade 3 or higher Drinking Water Treatment Operator or Wastewater Operator certification.
- For a AWTO Grade 4 certification, the minimum qualification for entry to the exam is having obtained the AWTO Grade 3 certification.
- For a AWTO Grade 5 Certification, the minimum qualification for entry to the exam is having obtained the Level AWTO Grade 4 certification.
This recognizes operators will also have the appropriate State certification for their position and the AWTO is an add-on certification.
Who is developing the certification?
The California-Nevada Section of the American Water Works Association (CA-NV AWWA) and the California Water Environment Association (CWEA) are jointly developing this certification program.
The AWTO Certification Committee is led by:
- Toby Roy, Chair, San Diego County Water Authroirty
- Gordon Williams, Vice-Chair, East Bay Municipal Utility District
- Erin Mackey, Secretary, Brown & Caldwell
The Committee has 4 work groups:
-
Examination development
-
Education development
-
Legislative and regulatory changes
-
Communications and outreach
If you would like to volunteer for the AWTO Certification Committee, please contact us.
What do I need to study to prepare for the exam?
We are going to prepare a “Need to know guide” and list of study reference materials that should be ready in early 2019. Then in the Spring of 2019 we’ll release the AWTO certification candidate handbook.
Be sure to sign-up for our email list so we can notify you when these materials are ready.
Other schools and associations may also develop AWTO training programs.
Do water professionals support this certification?
A majority of water and wastewater professionals have said they support the development of this certification. 70% of respondents to a WateReuse poll of water professionals agreed one certification process should be used for AWT Operators (WateReuse report, 2016).
California and Nevada already issue treatment operator certifications, so why another certification?
They do and those certifications are required if you want to work at a drinking water, resource recovery or water reuse facility.
However, water industry experts, associations and regulatory agencies agree that the current treatment operator exams are not sufficient. The existing water and wastewater treatment operator exams do not cover advanced water treatment or potable reuse-specific regulations and concerns. In 2017, the associations CA-NV AWWA, CWEA, WateReuse California and CUWA all agree a new treatment operator certification is needed.
What can agencies do to support the development of this certification?
We need your agency’s support! Here’s what you can do:
- Invite us to give your management team and/or operators a presentation about the AWT Operator Certification. Contact Alec Mackie at CWEA, 510.382.7800 x114
- Contribute to the fundraising effort to help CA-NV AWWA and CWEA launch this major new certification program. Agencies have contributed anywhere from $5,000-$30,000 to the program to help us hire the vendors, consultants and do the outreach necessary to launch this certification in 2018-2019. Contact Alec Mackie at CWEA, 510.382.7800 x114
- Volunteer some of your top operators to be subject matter experts. Contact Steven Garner at CA-NV AWWA, 916.889.8465.
