STEPS TO BECOME A WASTEWATER TREATMENT PLANT OPERATOR
To work in a public wastewater treatment plant or a private wastewater treatment plant regulated by the PUC, you must have a valid wastewater treatment plant operator certificate or an operator-in-training certificate. There are three major things that you must do to get certified:
- You must take courses in wastewater treatment plant operations. The number and difficulty depend on the certificate grade you want. Specialized training courses can be obtained from a community college or correspondence courses through the Office of Water Programs at the California State University, Sacramento.
- You must pass a written exam. Wastewater treatment plant operator certification exams are given twice each year, once in early April and once in early October. Exas for all five grades are given at the same time at several locations throughout the state. To take an exam, you must show that you meet the minimum educational requirements and submit a fee and application.
- You must meet experience requirements and submit a fee and an application for a certificate. Your experience must be in the operation of a wastewater treatment plant with a valid operator certificate or operator-in-training certificate. You may submit your application for a certificate up to four years after you pass the written exam.
If you have no experience as an operator, you must get an Operator-in-Training (OIT) Certificate. The owners of the plant do the hiring of operators, usually a city, county or special district. You need to contact them to see if there are any jobs available. Other potential sources of job listings are local newspapers local sections of the California Water Environment Association.
