Advances in septic systems have increased ease of use and dramatically improved groundwater quality. Here are a few of the more popular types of septic systems. ( For even more types, visit the Environmental Protection Agency’s list.)
Conventional Septic System
Typically installed in a single family home or small business, the conventional system uses a septic tank followed by a leaching field. For an overview of this system check out Septic 101. While effective, gravel/stone drainfield systems require a relatively large footprint.
Chamber System
Used for over three decades in areas of the US, this gravelless system requires a smaller footprint and can be manufactured with recycled materials. The Chamber System is one example of the gravelless system. This system of interconnected chambers is easier to deliver and install. They can also work well in areas with high groundwater tables, or where the system’s usage could vary seasonally.
Aerobic Treatment Unit
Like a mini municipal sewage treatment plant for your house, Aerobic Treatment Units (ATUs) use the same system of injecting oxygen into the tank to increase bacteria levels, but on a smaller scale. Suitable for homes with smaller lots, less-than-ideal soil conditions, high water table or proximity to bodies of water, ATUs can be a good option when conventional systems aren’t feasible.
Mound or Raised Septic Systems
In this variation of the conventional system, the leaching field is contained within a trench in a sand mound. A pump system releases effluent at prescribed intervals. Mound Systems can be a good solution for areas with shallow solid or bedrock, or high groundwater. But they need more space and maintenance than some other systems.
Shared Systems
A septic treatment system that collects and treats the wastewater from two or more homes and in a site nearby, Shared Systems are used in areas such as rural subdivisions where a common owner manages the system.
