The most common gravel-less trenches now used include either long, narrow, tunnel-shaped chambers in the trenches or gravel substitutes such as expanded polystyrene aggregate. These gravel-less trench designs rely on alternative materials in place of the gravel. Since the mid- to late 1990s, the traditional gravel aggregate trenches used in the past have given way to newer gravel-less trench designs. This system has a septic tank and a drainfield with gravel-filled trenches (usually two to six trenches). Many different kinds of septic systems are used in North Carolina, but most of the nearly 2 million systems in use throughout the state are slight modifications of the conventional septic system.
