The expense related to the change of its septic installation is nothing to cheer about. Our experts explain to you the main important factors for the installation of a new septic installation according to your reality.
How much does a septic tank replacement cost? This is definitely the most popular question we have to answer every day at Soluo.
Unfortunately, it is not possible to give the cost of replacing a septic tank, or of a complete septic installation without obtaining other key information to evaluate the costs of a septic installation. We are therefore presenting you today the 5 key factors that come into play to establish the cost of replacing a septic system.
- Type of work required
- Characterization of your land
- Possible type of septic installation
- Accessibility of the work area
- Additional work required
First, it is essential that a qualified professional accompany you in order to establish what work is really required at your home since the cost of replacing a damaged pipe represents a few hundred dollars and the replacement of a complete installation calculated in thousands of dollars. You have to know if your septic system reached the end of its life or simply one of its components needs to be replaced?
A diagnostic visit by a septic installation expert could save you from the hasty expense of completely replacing an installation and assist you in replacing a faulty element that is affecting the proper functioning of your septic installation. If your septic installation is really at the end of its life, we move on to the next factor!
2. Characterization of the terrain
In Quebec, all septic systems are governed by the regulation on the evacuation and treatment of wastewater from isolated residences (Q-2 – r.22) of the law on the quality of the environment. This by-law establishes the rules for the location of a septic installation according to the characterization of the land. In summary, the percentage of slope, the area of infiltration available and the distance with key elements (watercourse, well, house, etc.) exert an influence on the type of septic installation possible to build on your ground. It is therefore the characterization of your land that confirms to us what type of septic installation it is possible to build on your land.

3. Type of septic installation
Once the characterization of your land has been carried out, we now know what type of septic installation is possible depending on the characteristics of your land and the number of bedrooms in your residence. Know that qualified professionals have the duty to proceed with the selection of the septic installation by eliminating the solutions according to the regulations. They cannot therefore offer you the installation of a retention pit, if it is possible to make a septic field on your land according to the regulations.
The price of each type of installation varies greatly depending on the land on which they will be installed. It is therefore difficult to decide on the exact costs without having visited the site and knowing the constitution of the soil, but you can easily know what the direct cost of the material necessary for the realization of these installations is.
| Installation type | Cost of direct material (Casing, Pipes, etc.) |
|---|---|
| Retention tank | 3 000 to 6 000$ |
| Septic tank with leaching field | 5 000 to 8 000$ |
| Septic tank with advenced secondary treatment and a polishing field. | 10 000 to 16 000$ |
| Septic tank with advanced secondary treatment and UV or dephosphoration treatment. | 20 000 to 45 000$ |
It is important to note that to the cost of direct materials, we must add the installation time by a company specializing in septic installation as well as the aggregate (Stone, Sand, etc.) necessary to carry out the work according to the rules of art.

4. Accessibility of the work area
The place where the work must be done is also of great importance in calculating the price of a septic installation. An installation of the same type carried out on two different sites could have a very different final price. The reduced accessibility of the machinery to the work area could require adapted or additional machinery and therefore an additional length of work. In short, a septic system installed in a field in Montérégie and a septic system installed on a mountainside in the Laurentians will certainly not have the same price, even if the type of soil and equipment required are similar.
5. Additional work required
To maximize the lifespan and operation of your septic system, some additional work may be required depending on your land. For example, some drainage work to manage water flow or retaining walls to support your new septic installation may be required. This additional work must be calculated in the total price of your septic system since they are essential for its proper functioning.
In summary, you will understand that this essential information has a significant influence on the final price of your septic installation. To get an idea of the cost of a septic installation, do not hesitate to try our online price calculator or contact a Soluo expert to discuss your project.
