Operator Certification

There are three prerequisites to certification: training, experience, and an application form.

Part 5-4 of the New York State Sanitary Code requires operators of community public water systems and non-transient non-community public water systems to be certified. The Environmental Conservation Code requires sewage treatment plant operators to be certified.

Part 6-1.21(b) requires pools larger than 3,000 square feet or using gas chlorination to be maintained by a qualified swimming pool water treatment operator.


Contact the New York State Department of Health if you haven't received yours to obtain your renewal form. You must obtain your contact hours for your renewal application through training.
