There are different ways to treat sewage or wastewater that comes out of our houses, places of business, and schools. These include centralized sanitary sewer systems that empty into large municipal wastewater treatment plants or package plants, leaching trenches, elevated mound systems and drip distribution systems.

Leaching trenches, elevated mound systems and drip distribution systems rely on storage and treatment of solids in an aeration or septic tank. The liquid or effluent is then distributed to the field for soil based treatment on site. Larger centralized systems collect all of the wastewater and it is then transferred to a central point to be treated. These systems are inspected by the Ohio Environmental Protection Agency. Residential Services Unit staff primarily handles reviewing installation and maintenance of Onsite Sewage Treatment for private homes, businesses and schools.

The Residential Services Unit Sanitarians work very closely with homeowners and contractors to ensure the best available sewage system is installed and approved. There is a strong emphasis on first evaluating the soil to determine the most appropriate treatment option for wastewater produced in a residence. This is because each individual lot has its own soil types and characteristics.

Our Sanitarians play a vital role in reviewing soil reports and making sure homeowners are educated about their options related to onsite wastewater treatment. We work to ensure that onsite sewage treatment systems, public or private do not create public health nuisances and jeopardize drinking water. More information on the services we provide and links to pertinent information related to sewage treatment can be found on this page.
