Residential Sewage
Disposal Systems Onsite regulations for Indiana were last updated in December 1990. Regulations are currently under revision and all sections are expected to be revised within the next year. Indiana defines innovative technologies as any system other than a conventional gravity absorption field system. An experimental technology is considered any system not permitted by current state rule or any design variation permitted by current state rule that may affect system performance. Indiana allows the use of several alternative technologies. Aerobic treatment units (ATUs) are permitted; however, they must discharge to an absorption field that meets minimum requirements outlined in the rules. At-grade soil absorption systems are permitted as an experimental system. Pressure distributed and flood dosed subsurface trench systems are permitted by rule. Gravelless/Chamber systems are permitted if they are sized according to the state rule for system sizing. Any downsizing of the required absorption areas for these systems is considered an experimental system. Mounds are permitted by current state rule. Constructed wetlands are permitted as experimental pretreatment before discharge to downsized absorption fields. Indiana requires National Sanitation Foundation (NSF) certification for ATUs. Within the state, fees for licensing, permitting, and special uses for individual systems are administered by local health departments. There are no fees for state services. Dr. Joseph Yahner or Ms. Catherine Taylor with Purdue University, can be contacted at the below address and telephone number concerning ongoing demonstration, research, and testing projects within Indiana. Agronomy Department The local health departments administer onsite septic/liquid waste regulations. The Indiana Department of Environmental Management administers the municipal and industrial waste regulations. The Indiana State Department of Health sets minimum standards through the state rules for the local health departments to follow; operates the experimental onsite sewage disposal program; provides education and training for local health department personnel and contractors; provides educational materials and bulletins; provides program support and technical assistance to local health departments; and acts as a liaison to other state agencies and other states. Indiana Department of Environmental Management is responsible for all municipal onsite sewage disposal systems. Indiana State Department of Health is responsible for all privately owned commercial onsite sewage disposal systems.
