Webinar by SDARWS















*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 w/ 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.

All dates are tentative based on number of applicants. Certification exam applications must be submitted for ALL exams including retakes. Applications MUST be received by the Department of Environment and Natural Resources (DENR) at least two weeks before the exam date, as required by the Operator Certification Rules (ARSD 74:21:02:40).  Applicants will receive a confirmation of their exam receipt by the Department.  Applications will be accepted via fax at 773-5286. Check or money orders made out to "DENR-Operator Certification" are required.  Applications must be filled out completely as they are the sole source of information used to determine operator eligibility to take an exam.  

The following must have a certified operator in direct responsible charge of their system:

  • All wastewater treatment or wastewater collection systems that serve more than 500 people.
  • All transient non-community water treatment systems using surface water or groundwater under the direct influence of surface water or treating with a disinfectant (chlorine, chlorine dioxide, ozone, etc.).
  • ALL community and non-transient non-community (NTNC) water treatment/distribution systems regardless of size.  

The following operators must be certified:

  • Any operator in charge of one of the above water or wastewater systems.
  • Any operator making process control/system integrity decisions affecting water quality/quantity at a community or NTNC water system must be certified at any level.
  • An operator certified at the designated level of the treatment plant/distribution system must be available for each operating shift at a community or NTNC water system.
