Types Of Septic Systems

Conventional Septic Systems

Conventional septic systems are the most common type used for residences or small businesses. They are comprised of a septic tank and a ditch or bed subsurface wastewater infiltration system. Waste drains into a small ditch, which is usually filled with rock or gravel, and subsequently percolates through the gravel to be treated by bacteria in the soil underneath. Conventional systems are ideal for larger lot sizes.

​

Gravity Septic Systems

A gravity system is a conventional type of septic system that doesn’t use pumps, compressors, or other complicated equipment. When you use gravity to your advantage, you can save on installation and repair costs. With gravity fed systems, all the water and sewage from your sinks, showers, and toilets is carried to the septic tank through pipes by gravity.

​

Aerobic Septic Systems

Aerobic septic systems, or ATUs (aerobic treatment units) are ideal if you want the waste to be treated to a higher standard. Aerobic systems are also great for smaller lot sizes, as the leach field can be smaller. They work by forcing oxygen into an aeration chamber using a compressor or air blower. This helps stimulate natural bacterial activity within the system. In cold-weather climates, this type of system requires insulation.

​

Septic Mound Systems

Septic mound systems are best used in areas where the soil cannot support a traditional septic system. With a mound system, the drain field is carefully constructed of sand and gravel. Waste exits the tank and is pumped through the layers of sand and gravel using a network of pipes. While mound systems often have lower installation costs, they can be more complex to maintain and repair.
