As you would imagine, Standard Gravity Septic systems allow gravity to take waste to a septic tank where natural bacteria breaks down waste before being gravity fed into a series of underground trenches called a leaching field or drainfield. While often the most cost effective solution, basic gravity systems require the leaching field to be at a lower elevation than the septic tank and require the bottom of the leaching field trenches to be at least 3 feet above any restrictive layer such as hardpan or bedrock.

Advanced Treatmentt systems are most often used when soil depths on a property don't allow traditional systems. Advanced Treatmentt systems come in many shapes, sizes and designs but effectively add the function of cleaning waste water before it is expelled into the ground - often in tandem with a pressure distributed leaching field. Some of the most common types are sand filtered systems, sand mound systems and Aerobic Treatment systems.
