SCDHEC Onsite Wastewater Systems (Regulation 61‑56) Practice Test

The components that are typically considered part of an onsite wastewater system include septic tanks, leach fields, collection units, and treatment units specifically designed to manage wastewater from residences.

Grease traps and similar holding systems, while important in managing grease and larger food particles from kitchen drainage and preventing clogs, are not generally classified as components of an onsite wastewater system in the context of Regulation 61-56. These systems are typically found in commercial kitchens or specific wastewater treatment facilities and do not directly contribute to the main residential wastewater disposal processes.

Understanding the distinction between these components is key in identifying what constitutes an onsite wastewater system versus ancillary systems that may be used for specific purposes. This clarity is essential for anyone involved in the design, installation, or management of onsite wastewater systems.
