In NC septic system terminology, what defines an 'alternative system'?

An alternative septic system is defined by design that deviates from a plain trench with no engineered components and relies on engineered treatment or distribution methods to handle wastewater. In North Carolina, these systems are used when site conditions prevent a conventional system or require enhanced treatment, so they include devices or configurations like mound systems, advanced treatment units, sand filters, or pressure distribution. A standard conventional trench system uses a septic tank and a simple, non-enhanced drain field, so it does not fit the definition of an alternative system. The key idea is that alternatives involve engineered components to achieve treatment or distribution beyond a basic trench setup.
