How a septic system works can sometimes be difficult to understand. Our experts present the 3 steps that are an integral part of a septic installation.

Above all, it is important that you know the type of septic system you have at your home in order to fully understand the flow of water in your home. To help you understand, some municipalities are able to send you the history and details of your septic installation if it was designed and installed after the arrival of the provincial regulation.

First step: Retain the waste

When using all your plumbing items such as a sink, shower and toilet, water and solids are directed outside by gravity or pumped to your septic tank or sump pit.

The role of the septic tank is to retain the solids by a principle of decantation and to let the water evacuate towards a next element. For its part, the sump will retain water and solids in the same place.

Second step: Treat the water (If necessary)

This second step is only necessary for land that has soil conditions less favorable to infiltration or on land with a small area. Additional treatment is therefore required in order to allow you to still infiltrate the water on your land or discharge it into the environment.

There are 5 different technologies approved by the Bureau de la Normalisation du Québec :

  • Bionest
  • Ecoflo
  • System O (Previously known as Enviro-Septic)
  • Hydro-Kinetic
  • Ecophyltre (Previously known as Roseau Épurateur )

Each of the technologies makes it possible to reach the treatment standards allowing then to infiltrate or reject the water according to your land. We invite you to consult our articles on each of the technologies in order to fully understand how they work.

These technologies all require an annual maintenance contract with the manufacturer. This will guide you in the evolution of your system and on the particularities of the technology that you have chosen with your professional.

Step Three: Infiltrate the Waters

Once the septic tank has done the work of retaining the solids, and if needed, the advanced treatment treated the water, the water goes to an infiltration surface to continue its treatment. Commonly, this element is called the “Purification field” but we mainly use the notion of purifying element.

The soil conditions and the size of your land guide the professionals in order to establish the necessary surface to allow water to infiltrate adequately. If the conditions are not suitable for the installation of a conventional purifying element, your professional will recommend that you set up a second treatment before being able to infiltrate your water, in order to reduce the surface area necessary for water infiltration.

Once the waters have seeped into the ground, the water path is complete! You now know the basics of how a septic system works.
