Septic Systems 

What happens when you flush the toilet? Many people don’t know! Every time you flush the toilet or use water in any way in your home, you are generating wastewater. When wastewater leaves your home it needs to be treated before it re-enters the environment. Depending on the type of septic system or Sewage Treatment System (STS) you have your wastewater is treated naturally by the ground, with the help of special filter bed or by an aerator. To find out more about your system type and how it treats your wastewater follow this link to our septic system information page.

What you need to know

Sewage is the waste water released by residences, businesses and industries in a community. It is 99.94 percent water, only 0.06 percent of the water is dissolved and suspended solid material. The cloudiness of sewage is caused by suspended particles. Pathogens or disease-causing organisms are present in sewage. Coliform bacteria are used as an indicator of disease-causing organisms. Sewage also contains metals, minerals and nutrients (such as ammonia and phosphorus).

Private sewage systems are used by households not served by a centralized sewage system. This is accomplished by site evaluations, permits and inspections of new and altered systems, and the investigation of complaints/malfunctioning systems. Union County regulates private sewage systems in accordance with the local sewage treatment system rules, Ohio Revised Code (ORC) 3718, and the Ohio Administrative Code (OAC) chapter 3701-29.

Public sewage systems are those systems where households are connected to a centralized sewerage system. Public systems are not regulated by the Health Department, but are governed by the Ohio Environmental Protection Agency (OEPA). However, in Union County, any commercial (or semi-public) sewage system smaller than 25,000 gallons per day is inspected by the Health Department, through a contract with the OEPA

Installing a private sewage system?

Installing a private sewage system requires a permit from the Union County Health Department. There are several steps that must be completed before a permit can be obtained. Some of these steps include a site evaluation. A soil scientist must test the soil in which the system will be installed.

Once a permit is issued, installation must be done by a registered installer.  Click here for a list of registered installers.
