Why Become a Water System Operator?

Operator certification helps protect human health and the environment by establishing minimum professional standards for the operation and maintenance of public water systems. While the specific requirements vary from state to state, the goal of all operator certification programs is to ensure that skilled professionals are overseeing the treatment and distribution of safe drinking water. Operator certification is an important step in promoting compliance with the Safe Drinking Water Act (SDWA).

Maryland classifies water facilities according to treatment technology. This ensures that operators are technically qualified for the process they are certified to operate.

The operator and superintendent must have certification that matches the water system’s classification.  Certain classifications of certificates also authorize the holder to operate other classifications of facilities.  Table 1 presents the classification of water systems and outlines the typical treatment processes found in each classification.

A temporary operator is defined as an operator who works under the direction of a certified operator or superintendent, and is employed at a water system, but has not met the experience requirements for the classification and/or has not passed an examination for the classification.  This type of certificate is only used for operators in training.
