What is a mound septic system?
There are soils and places that do not meet the conditions for installing traditional septic systems, such as Conventional Septic Systems. In these cases, it is necessary to install alternative septic systems that will ensure efficient operation and a high level of wastewater treatment.
Today you will find several different types of alternative septic systems. Among them are the Mound Septic Systems. This type of system is suitable for areas with shallow soil depth, high groundwater, or the presence of a rock base.
The Mound Septic Systems are an excellent solution for areas where the technicians cannot install other types of septic systems. However, what is specific is that they require more space and much more frequent maintenance than different types of septic systems.
The Mound Septic System provides:
- Dosing and resting cycles;
- Uniform distribution of wastewater;
- Wastewater treatment in sand fill before disposal;
- The longer distance that wastewater should travel before reaching groundwater.
How does it work?
The main aim of the Mound Septic System is to treat and purify the wastewater that comes from your home. After it leaves your house, its first stop is the septic tank. There the wastewater is divided into three main layers – the scum, effluent, and sludge.
The scum is the top layer, and it contains all the lighter solids, oils, and fat. The thickest layer is formed in the middle, which is a liquid. It is known as effluent. The bottom layer, the sludge, consists of all solid particles that settle at the bottom of the septic tank.
When the effluent exceeds the preset level, the pump control float is switched on, and the water begins to flow into the pump chamber, where in small doses, it begins to be sent through the pipes and evenly distributed in the drainfield. There, effluent passes through sand and soil to be treated and to destroy harmful viruses and bacteria.
Sub-Types of mound septic systems
The Mound Septic System is divided into two main sub-types.
The Sand Filter Mound Septic System is the first sub-type of the Mound Septic System. The specialist can install the system both above and below ground. When the wastewater reaches the septic tank, it is directed and goes to the pumping chamber.
There, the wastewater is pumped into the sand filter. This sand filter acts as a purifier, as it will carry out the three main processes of wastewater treatment before being directed to the soil and flowing into groundwater.
The first process involves aerobic microbes that will absorb nutrients. After that, the solids will be filtered into the sand. Finally, the contaminants will adhere to the sand fill as the water descends to the drain field and directs into the soil through a chemical process.
The Micro-mound Septic System is the second sub-type of the Mound Septic System. It is an on-lot wastewater distribution system. Unlike Sand Filter Mound Systems, the Micro-mound Septic Systems are lower in placement. They direct the wastewater from the treatment tank to the sand layer.
This sub-type of a septic system is exceptionally suitable for sites with slopes between 0 and 15%. Other factors that make the Micro-mound Septic system convenient are sufficient soil depth, rock area, and high groundwater.
Components of the mound septic system
The Mound Septic Systems consists of three parts:
- As with the standard septic system, the septic tank is a container made of concrete, fiberglass, or polyethylene. It is the first stop on the wastewater that leaves your home. The wastewater that enters the septic tank is divided into three layers.
The heaviest solid particles go to the bottom, where they form the so-called sludge. It thickens over time, so the septic tank must be periodically pumped and cleaned. The lightest solids, fats, and oils form the top layer called the scum. The middle remains the thickest of all layers, namely effluent;
- The so-called effluent is the wastewater that leaves the septic tank and is directed to the pump chamber. The pump chamber is the second component of the Mound Septic System. It, like the septic tank, is a container made of concrete, fiberglass, or plastic.
Its function is to collect wastewater from the septic tank and direct it to the drain field. It happens in stages so that the effluent is evenly distributed in the drain field, and the system is not loaded.
The pump chamber consists of three parts, each of which performs a specific function. The pump serves to pump water from the septic tank to the pump chamber. On the other hand, the pump control floats take care of the pump control.
When the wastewater exceeds the preset level, the float turns on and distributes the water evenly to the drain field. When there is a problem with the pump, the third element, namely the high-water alarm float, turns on. If the alarm goes on, you need to call a specialized company to perform all necessary procedures;
- The mound is the third component of the Mound Septic System. The mound is a drain field. What distinguishes it from other drainage fields is that it is raised above the natural surface of the soil.
This specific mound consists of three layers. There is a layer of soil on top, then gravel, and the bottom layer is a particular sand fill. Within the sand, fill is a gravel-filled bed with a network of small-diameter pipes.
The septic tank effluent is pumped through these pipes to the drain field, controlling the doses of water that enter a uniform distribution. The effluent trickles down through the gravel and the sand.
As it passes through the sand, the effluent is purified, destroying all harmful bacteria and viruses. When the water goes through the necessary treatment, it goes into the natural soil.
Regular care for each component of your Mound Septic System will ensure extended system life. In this regard, you need to contact a professional company that will regularly maintain your system. We at Fresh Clean Septic have many years of professional experience in thе Mound Septic Systems maintenance.
Some of the key things that are part of taking care of your septic system:
- Regularly septic tank inspection and pumping. Septic Tank Inspection needs to be performed every year so that you can prevent any possible problems with the system. Along with this, it is necessary to pump regularly.
Pumping is usually done every 3 to 5 years, and sometimes much more often. It all depends on the type of the septic system, the size of your septic tank, the number of people living in your home, and the amount of water you use.
In this regard, alternative septic systems, such as Mound Septic Systems, require much more frequent pumping.
Each septic system is particular and requires its care. That is why it is necessary to contact a licensed company to conduct an inspection. Specialized technicians and inspectors will be able to assess the condition of your septic system and give you essential guidance;

- Do not add any additional chemicals to your septic tank. Many brands offer other chemicals, assuring that they will enhance the efficiency of your septic tank.

- Regularly check your pump chamber, the pump, and floats, as well as the pipes and electrical parts. If necessary, replace and repair them. To do this, contact a licensed professional company;
- Install a septic tank filter for wastewater in your pump. It will significantly improve the performance of your septic system;
- Make sure your Mound Septic System is not overloaded. One of the things you can do about this is to limit the amount of water consumed.

If your area has sandy soil, rocky areas, high groundwater levels, and the soil is challenging to seep through, then the Mound Septic System is the best choice for you.
In addition, if there is no central sewer system in your area, then the Mound Septic System is a must in your home. And since the installation and maintenance of the septic system is a particular job, we recommend that you turn to specialists who will give you the best guidelines for your case.
