Qualified and well-trained Drinking Water and Wastewater operators play a vital role in drinking water quality. The WSO Section is responsible for certifying public water supply treatment and distribution operators and Wastewater and lagoon operators as prescribed by Chapter 81 of the Iowa Administrative Code (IAC). The purpose of the OpCert program is to insure that water and wastewater operators have sufficient knowledge and experience to properly operate the system, and in turn protect human health and safety and the environment.
Operator Certification Database and Training Calendar
This database is a resource for the following:
Recognizing the need to protect the integrity of certification programs and to provide operator certification authorities with a definitive, peer-reviewed administrative standard and resource for program evaluation, the Association of Boards of Certification released Model Standards for the Administration of an Operator Certification Program. Certification authorities can use the industry-developed Model Standards as a review tool to improve the efficacy of programs and the operators they certify. This resource identifies best practices and provides a framework for aligning them to national and international standards. The State of Iowa was the first state certification program to use these standards for the purpose of Program Review.
