The Household Sewage Treatment System Program ensures that septic systems are designed and installed under permit and consistent with state and local regulations.
This program ensures the cleanliness and safety of our drinking water.
Public Health also investigates sewage nuisance complaints and consults with homeowners on replacing their septic system.
Aerator systems, which handle sewage and release the cleaned water into streams, ditches, and storm sewers, are important. If we don’t take care of them properly, they can break down and release untreated sewage. This can seriously harm public health and the environment.
