What Type of Septic System Should I Get?

There is no one-size-fits-all solution when it comes to septic systems. It is important that you choose a system that will suit your environment, since different types of septic systems are designed around different environments. The various types of systems available fit into two broad categories. Namely conventional septic systems and alternative systems. Let’s take a closer look at these to help you determine what is right for you.

Should I Get a Conventional System?

As the name implies, a conventional system is the most commonly used system for residential and commercial use. A conventional septic system consists of an underground tank that is connected to your toilet, an effluent tank and a drain field. When you flush your toilet, your waste enters into the tank, where it is stored. Gradually, this wastewater will form two distinct layers: solids/sludge and effluent. The sludge is what you’ll find sitting at the bottom of the tank. Here, healthy bacteria digest this and break it down. The top layer consists of the effluent, otherwise known as grey water.

When your tank fills up, the grey water spills out into the effluent tank and is then gravity fed or pumped out of the tank and makes its way to the drainfield (which comprises a system of underground pipes that are covered in permeable soil or gravel with natural bacteria that help clean up any toxic matter).

Having an environment with plenty of permeable soil is thus a vital factor in your choice to install a conventional system. 

Should I Get an Alternative Septic System?

There are various types of alternative systems, such as intermittent sand filter systems, mound septic systems and aerobic treatment systems. These alternative septic systems are often used when environmental conditions aren’t ideal for the installation of a conventional tank. Such conditions could include high water tables and soil which is not conducive to sufficient drainage.

The defining characteristic of these alternative systems is the way in which wastewater is managed. For example, in an intermittent sand filter system, a sand filter is installed due to an environment with insufficient soil. Wastewater runs through this filter first and then it’s dispersed into the soil.

Clearly, choosing the correct septic system is extremely important if your waste is to be disposed of in an efficient and hygienic manner.
