Public water and wastewater treatment systems are operated by professionals that are certified by the State of South Dakota. Drinking water and wastewater treatment systems protect public health and the environment only if they are working and being operated correctly. The Operator Certification Program is intended to protect public health, environmental quality, and water/wastewater systems' investment in their facilities. A voluntary certification program was started in 1954. The mandatory certification law was passed by the South Dakota State Legislature in 1970. There are certifications in water treatment, water distribution, wastewater treatment, wastewater collection, stabilization ponds, small water treatment systems, and very small water systems. South Dakota's Water and Wastewater Operator Certification regulations are listed in the Administrative Rules of South Dakota 74:21:01-02, and the statutes are listed in South Dakota Codified Law 34A-3
Starting with the 2010 renewal, a sliding scale for required contact hours will be used depending on the number and type of certificates an operator holds. You may view the courses you have completed and the associated contact hours using the following search:

The Stabilization Pond class deals strictly w/ ponds and is the best class for preparing to take the Small WW System exam. The Basic WW Treatment class deals w/ all types of wastewater treatment other than ponds and is the best class for preparing to take the Class I WW Treatment exam. Small systems that use ponds for treatment can come into compliance with the OpCert Law by passing either the Class I WW exam or the Small WW System exam.
Water systems serving less than 500 people that use wells can come into compliance by passing the Small Water Treatment exam. Larger systems must pass the Class I Water Treatment exam.
