Shelby County Permit Requirements
Septic System Permit: Shelby County Health Department issues permits for new OSDS installations, major repairs, and system modifications. New construction on unincorporated Shelby County property that can't connect to municipal sewer must obtain an OSDS permit before construction proceeds.

The Memphis Metro Geographic Context
Shelby County encompasses the City of Memphis and extensive suburban and rural areas. The unincorporated portions of the county that rely on private septic are generally in the county's outer rings, away from Memphis's urban core, which is largely served by the Memphis Light Gas and Water sewer system.
The Memphis area's geography creates specific OSDS design considerations:
Memphis Sand Aquifer: The Memphis Sand aquifer is a major drinking water source for the Memphis area. OSDS on properties above or near this aquifer must be designed to protect groundwater quality. The aquifer protection zone affects OSDS design and setback requirements in some areas.
Mississippi Alluvial Plain: Parts of Shelby County are on flat alluvial terrain with high seasonal water tables. High water table conditions affect OSDS design, often requiring mound systems or elevated drainfields.
Loess soils: The Memphis area's distinctive loess soils (wind-deposited silt) have specific drainage and percolation characteristics that affect OSDS design.
Wolf River watershed: The Wolf River flows through Shelby County to the Mississippi River. OSDS near Wolf River tributaries face water quality protection considerations.
Permit Application Process in Shelby County
The standard OSDS permit process in Shelby County follows Tennessee TDEC's framework:
Application and site evaluation: Submit the permit application and request a site evaluation. Shelby County Environmental Health schedules a site visit to assess soil conditions and site suitability.
System design: For sites determined to be suitable, the site evaluation results inform the system design. Many designs can be prepared by the licensed installer; complex sites may require engineer involvement.
Permit issuance: After reviewing the application and proposed design, Shelby County Health Department issues the installation permit.
Installation by licensed installer: A Tennessee-licensed installer performs the installation per the permit.
Final inspection: Shelby County Health Department inspects the completed installation before covering.
Common System Types in Shelby County
Conventional gravity systems: For sites with suitable soil conditions and adequate depth to limiting layers.
Mound systems: Common in areas with high seasonal water tables, where conventional burial depth isn't feasible.
Pressure distribution systems: For sites where soil conditions benefit from controlled effluent distribution.
Alternative systems: Tennessee TDEC rules permit alternative systems for challenging sites with appropriate design and, in some cases, TDEC approval.
