What is an alternative septic system?
The Alternative Septic System differs from the traditional septic system. It is a solution for sites with a rock base, the soil depth is not enough, or there is high-located groundwater. In these cases, traditional septic systems would not be suitable, so in their place come the alternative ones.
What distinguishes the Alternative Septic System from other species is that it requires less soil. It means that the drainage field is smaller, the standoffs to the water table and soil restrictions are reduced.
This type of septic system is more complex and advanced than traditional ones. The Alternative Septic System includes more equipment and processes that are necessary for its proper functioning. All this means that it requires more specific maintenance than other septic systems.
That is why it is necessary to regularly contact a licensed company to assist you in caring for the alternative system and give you guidelines in its proper use. It will prevent the Alternative Septic System from malfunctioning and causing problems affecting public health and the environment adversely.
How does it work?
As mentioned above, Alternative Septic Systems do not require a large amount of soil or a large drain field. But they use a standard septic tank like traditional systems. The only difference is that the leach field is made of interlocking polyethylene arches that provide a continuous drainage area. In this way, chambers create a space through which wastewater can pass. In these cases, it is not necessary to add gravel or geotextile.

Sub-types of alternative septic systems?
There are three types of Alternative Septic Systems:
Aerobic Treatment Unit
The Aerobic Treatment Unit works similarly to standard septic systems. Both types of septic systems treat wastewater using natural processes. The difference is that the Aerobic Treatment Unit uses oxygen which breaks down organic matter.
What is specific about this type of septic system is that the decomposition process is much faster. It helps for better water purification. Once the septic system has performed all the necessary operations, the result is cleaner water. And this, in turn, makes Aerobic Treatment Units suitable for installation in environmentally sensitive areas.
Another characteristic of the Aerobic Treatment Unit is the so-called suspended growth process, which takes place in the aeration chamber. In this process, the air mixes with the wastewater. It allows the bacteria to float freely and grow. When they become large enough, they begin to absorb solids.
In rare cases, Aerobic Treatment Units may have a second aeration chamber connected to the first. It is used for the further processing of solids. Some of the solids fail to be broken down by bacteria, so they settle. Here is the role of the second aeration chamber. The solids are returned to the first chamber by gravity or pumping to undergo the decomposition process again.
Some of the advantages of the Aerobic Treatment Unit are:
- Better wastewater treatment, unlike other septic systems;
- Helps to protect water resources in areas where there are non-functioning septic systems;
- An alternative option for sites with inappropriate conditions, such as soil, size, and others;
- Extend the life of the drain field;
- Reduces discharged ammonia to receiving waters.
Mound Septic System
The Raised Bed Septic Tank Systems, also known as Mound systems, are alternatives in cases where standard septic systems are not suitable.
The Mound Septic Systems have three main components, namely:
- septic tank
- pump chamber
- mound – this is the drain field
What characterizes this sub-type of alternative septic systems is that the wastewater first goes into the septic tank. In it begins the process of decomposition of solids.
In the septic tank, wastewater is divided into three main layers. The first, the top layer, is made up of light solids and fats known as scum. In the middle is the layer formed by effluent. And at the bottom are deposited all the heavy solid particles that form a sludge.
When the wastewater in the septic tank reaches a certain level, it begins to move to the pump chamber. From there, very evenly, continue to the drainage field. In it, the wastewater is additionally treated by passing through a sand fill.
This sub-type of alternative septic systems provide:
- Dosing and resting cycles;
- Uniform distribution of wastewater;
- Wastewater treatment in sand fill before disposal;
- A longer distance that wastewater travels before reaching groundwater – provides better water purification.
Sand Filter Septic System
Sand Filter Septic System is the third sub-type of Alternative Septic Systems. This system is also suitable for areas where conditions do not allow a standard septic system installation.
The Sand Filter Septic System has four main components. These are:
- septic tank
- sand filter
- pump chamber
- drain field
When wastewater leaves your home, it goes directly into the septic tank. In it, they will go through the necessary purification processes. When the procedure completes, the water flows into the pump chamber, and then it is pumped out into the sand filter.
In the sand filter, wastewater goes through three main processes:
- (1) Aerobic microbes absorb some nutrients in the wastewater;
- (2) The solids shall be filtered by the sand;
- (3) And the last step is starting a chemical process in which the contaminants adhere to the sand grains.
When the wastewater goes through all the necessary treatment processes, it is directed to the drainage field, where it descends into the soil and flows into the groundwater.
Components of the alternative septic system?
The Alternative Septic Systems consists of three main parts:
- The septic tank of the Alternative Septic System is a container made of concrete, fiberglass, or polyethylene. It is the same as standard septic systems, as this component is the first stop of the wastewater. As we shared above, in a septic tank, wastewater is divided into three main layers.
The heaviest solid particles go to the bottom, where they form the so-called sludge. Over time, this layer thickens, so a professional company must periodically clean the septic tank. The lightest solids, fats, and oils go to the top and form the top layer called the scum. The thickest layer is structured in the middle, namely effluent;
- The so-called effluent is the wastewater that leaves the septic tank and is directed to the pump chamber. It is the second component of the Alternative Septic System.
The pump chamber 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 uniformly distributed in the drain field, and the system is not loaded.
The pump chamber consists of three parts, each of which has a specific function. The pump serves to pump water from the septic tank to the pump chamber. In turn, 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. If there is a problem or damage with the pump, the third element will turn on, namely the high-water alarm float. In cases when the alarm goes on, you need to call a specialized company to assist you;
- The drain field is the third principal component of the Alternative Septic System. It differs from the drainage fields of other septic systems. What is specific is that the drain field is raised above the soil’s natural surface. It consists of three layers – soil on the top, gravel in the middle, and a specific sand fill in the bottom.
In this sand filling, there is gravel around the pipes. The septic tank effluent is pumped through these pipes to the drain field, controlling the water doses that enter. Wastewater passes through this specific sand and moves through the natural soil. During this process, the wastewater is treated, and all harmful bacteria and viruses are destroyed.
Why do we need it?
There are areas where environmental conditions do not allow the installation of a standard septic system. Such conditions may be the presence of shallow soil, rock base, or high groundwater. Installing a traditional septic system in a site with similar conditions can lead to system malfunction and significant damage.
In these cases, you must install an Alternative Septic System. They are designed to replace traditional ones by providing efficient wastewater treatment.
What kind of problems can occur?
When it comes to Alternative Septic System maintenance, some of the main problems you may encounter are:
- An overcrowded septic tank. It may be due to improper maintenance or infrequent pumping and septic tank cleaning. Signs for problems with the septic tank can be foul odors, overgrowth, wet spots around the septic tank, slow draining, bubbling, returning water to you, etc;
- Improper functioning of the drain field. Drainage field problems can also come from the septic tank. To find out where the problem is coming from, you need to contact professional technicians to perform a septic system inspection and locate the problem;
- Clogged pipes. They can also be the result of a malfunctioning septic system. So the regular inspections and procedures for the maintenance of the septic tank are needed.
What type of service do we need according to the issue we have?
- Septic System Inspections are performed by highly qualified inspectors who will test your septic system.
