SYSTEMS
Approximately 645 public water systems (PWS) currently exist in South Dakota. A public drinking water system is a system serving 25 or more people. Each public water system must operate, monitor, and maintain their system to meet the drinking water standards outlined in the Drinking Water Program. » Each South Dakota resident uses roughly 85 gallons per day. » Each system requires a water operator that has completed State of South Dakota certification by demonstrating their technical knowledge of water treatment systems, in addition to continuous education requirements. Completion of certification is difficult because of the technical nature of the exams. + In 2024, 627 exams were administered at all levels of both water and wastewater certification with a 55% pass rate . Successful exam completion often requires studying, preparation, and multiple attempts to pass. + There are currently 14 community systems without a certified water or wastewater operator per South Dakota’s Operator certification laws.
Maintenance Treatment systems, pumps, and pipes have a life cycle of 20 to 30 years. The age and condition of water infrastructure prompts both preventative and emergency maintenance to address issues such as water pipe breaks and pump failures. An example of how the State is addressing future needs is the South Dakota Lead Service Line Initiative , which is part of a nationwide effort to identify lead pipes that may require replacement. More information about the program can be found at the link below. Costs to operate and maintain water systems increase with cost of materials, growth of communities, energy costs, and labor. Value of Water The availability of clean drinking water is essential to the health of South Dakota, the cost of water has historically been low to ensure availability to all citizens. Cost to Supply
