Differences Between Conventional vs. Alternative Septic Systems in North Carolina

Not all septic systems are the same. Here’s what Piedmont Triad homeowners should know:

Conventional Septic Systems: – Gravity-fed, simple design – Tank + traditional drain field – Works well in suitable soils – Lower installation and maintenance costs – Most common in the Triad

Alternative Septic Systems:

Pump Systems: – Required when drain field is uphill from tank – Includes pump chamber and controls

Low-Pressure Pipe (LPP): – Distributes effluent more evenly – Good for challenging sites

Sand Filter Systems: – Pre-treats effluent before drain field – Used for poor soil conditions

Aerobic Treatment Units (ATUs): – Uses oxygen to treat waste – Higher treatment level – Requires more maintenance

When Are Alternatives Needed? – High water table – Clay-heavy soils (common in Piedmont Triad) – Small lot size – Poor percolation rates
