Septic Systems


The Office of Community Engagement’s is helping to raise awareness in Mississippi’s communities of the  importance of maintaining and properly caring for septic systems.

Septic Systems Overview

Many homeowners rely on septic systems for safe and effective treatment of their wastewater. Household wastewater is treated by a septic system before it filters into the soil. Recycled water from a septic system can help replenish groundwater supplies; however, if the system is not working properly, it can contaminate nearby waterbodies.  According to the EPA, more than one in five households in the United States depend on individual onsite or small community cluster systems (septic systems) to treat their wastewater.

Who regulates septic systems?

The Mississippi State Department of Health’s On-site Wastewater program develops policy and regulations, provides technical assistance, and inspects Individual On-site Wastewater Disposal Systems (IOWDS), recreational vehicle campgrounds/lodging parks, pumpers/haulers, and individual water supplies.

Do septic systems cause health or water quality problems?

When properly sited and maintained on a routine basis, septic systems are an excellent waste management alternative. However, when not properly sited or maintained, they can cause contamination of surface and groundwater resources, which leads to public health and pollution problems.  Click here for additional information.
