Pools & Spas
The Aquatic Facilities Program is responsible for approving and regulating public and semi-public pools, wading pools, special use pools and spas. Public and semi-public pools and spas are typically owned and operated by municipalities or businesses such as hotels, apartment complexes, homeowners’ associations, churches, schools and other governmental, non-profit or commercial enterprises.
The Division of Environmental Health and Protection licenses and inspects pools and other aquatic facilities in unincorporated St. Charles County, as well as in the cities of Dardenne Prairie, Lake Saint Louis, O'Fallon, St. Charles, Weldon Spring and Wentzville, to monitor proper operation and facility maintenance.
