Septic Systems - Onsite Wastewater Systems

The way our communities grow and develop can directly affect the health of current and future populations. Even small land use decisions can have widespread environmental impact.

For example, household sewage that is improperly disposed of may contaminate the groundwater, which could put the public at serious risk for disease.

Tri-County Health Department issued 900 septic system permits in the past year, as well as reviewing plans for new system installation and inspecting existing sites. These systems are known as an Onsite Wastewater System (OWS) or Individual Sewage Disposal System (ISDS).

Fee increases as of 7-07
