Types of Septic Systems in North Carolina

By Robert Jones Mar6,2024

North Carolina has three main types of septic systems: Chamber, Gravelless, and Aerobic. Choosing the right one depends on the conditions of your home and neighborhood. Listed below are some of the best practices for choosing a septic system. Read on for more information. Below are some tips to help you make the best choice for your home. Here are the main differences between them and the best uses for each.

Chamber septic system

A Chamber septic system is one of the most popular septic systems in North Carolina. It functions like a giant, long pipe but with slits in the sides so that effluent can flow out. While a traditional trench septic system requires a pit, chamber septic systems have much greater capacity. While chambers can be sized down to match a smaller pit, many states do not allow this.

The septic tank stores wastewater, which is carried to a drain field. This is where aerobic bacteria treat the liquid waste. The bacteria in the drain field break down the wastewater into a safe gas for human consumption. During the process, biomass is formed on the soil, sidewalls, and bottom of distribution pipes. This gas helps with the treatment process. However, a chamber septic system in North Carolina must be pumped every three to five years.

Maintaining a Chamber septic system in North Carolina is essential for preventing unexpected replacement costs. It is important to note that a Chamber septic system is designed to handle a certain amount of sewage daily. Consistently exceeding this amount can overload the tank. Excessive water use may cause the drain field to become saturated with excess solids. Consumer products that claim to jump-start or accelerate the action of bacteria in the septic tank are not recommended. Instead, they can cause a problem because the necessary bacteria are already in the sewage entering the chamber.

Gravelless septic system

Whether or not you need a Gravelless septic system in North Carolina depends on your location. In rural areas, a graveled system is required to handle home wastewater. This is not a problem in urban settings, but a gravelless system is the only option in rural areas. It would be best to consider how much space you have to install an absorption system and whether the property is in a floodplain.

A gravelless system is an excellent alternative to a traditional gravel/stone system. This alternative design has many advantages over its stone/gravel counterpart. It’s less expensive and easier to install. Gravelleless systems are ideal for locations with high groundwater tables or limited gravel access. They are also easy to install and are available in plastic. However, they require more space. So, a conventional septic system is still an excellent choice if you have a small property and don’t have much space to install a gravelless system.

The gravity-based system uses a series of connected chambers in a surrounding area filled with soil. Wastewater flows from the septic tank to these chambers via pipes. This soil then contacts wastewater and microbes that live in the soil. Then, the wastewater is treated. The system’s efficiency depends on how well it works. A Gravelless septic system in North Carolina requires a professional subsurface system operator.

Aerobic septic system

An aerobic septic system in NC may not be the most appealing option. Despite the increased efficiency and longevity of this type of treatment system, it is also the most expensive to install and maintain. If you constantly forget to make an appointment, you may want to reconsider. Instead, seek references from people who have had similar experiences and check with the wastewater management office in your area. Below are some pros and cons of installing an aerobic system in your home.

The basic concept of an aerobic septic system in North Carolina is the same as that of a conventional septic system. It involves installing small distribution pipes buried in a field or gravel bed. The pipes carrying wastewater from the septic tank flow through these chambers. During the process, the wastewater is in contact with soil cells, which digest and release harmless waste. As a result, the wastewater is safe for human consumption.

The next step in installing an aerobic septic system is determining the soil type available for treatment. In arid areas, ET septic systems may not be the best choice. They can be installed within two feet of the water table. Compared to LPD systems, ET septic systems require less maintenance. Because they are based on natural processes, ET septic systems are environmentally friendly. You should also know that ET systems do not use any chemicals.
