We have just purchased a chalet, which already has a septic tank. This is non-compliant and will need to be replaced shortly. So, I started the process to know the steps for replacing a septic tank. Surprisingly, it was by phoning entrepreneurs that I was able to identify what these steps were, I found the web poor in content for this purpose. Here is the summary of my research (for Quebec):
First step: Soil study
It is necessary to contact a company which will carry out the study of the grounds. This is a soil characterization study. Prices may vary depending on your industry. I contacted 3 companies and according to my research the costs ranged between $ 850 and $ 1050. This amount includes the site visit (soil analysis and projection of the necessary installations) as well as the production of the plans and specifications required by the contractor to carry out the installation.
I suggest you check the availability of the company, as there may be a waiting list of several months.
Also, it is this same company that will issue a certificate of conformity at the end of the work.
Second step: Estimate for the construction of the septic tank
Along with the quotation plans made in the first step, you can send these documents to obtain estimates from builders. These will often be identified as excavation companies.
Third step: Obtaining a permit from the city or municipality
Before starting the work, you will need to obtain a building permit from the city or municipality.
Fourth step: Carrying out the work
The excavation company can proceed with the work.
Fifth step: Attestation of conformity
The company that carried out the soil study returns to the site to carry out a certificate of conformity at the end of the work. You have to calculate between $ 400 and $ 450 for this step.
This certificate will then be sent to the city or municipality.
