Entry-Level Course for Drinking Water Operators (for Operators-in-Training)

The Entry-Level Course (ELC) is a mandatory course for all drinking water operators developed by the Ministry of the Environment. It provides new operators with a basic understanding of water characteristics and pathogens, treatment and distribution processes, and the regulations that govern water quality. This course is intended to complement the on-the-job training that Operators-in-Training receive from their employers.
Individuals who have received an operator-in-training (OIT) certificate from OWWCO must take the Entry-Level Course within 16 months from the date their certificate was issued or their OIT certificate will expire. When they complete the course, their OIT certificate will be renewed to three years from the date it was issued.
