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.
