Frequently Asked Questions

  • I would like to acquire some land and would like to know if I can build a septic tank and a well. What should I do?

    Contact us to have a technologist visit the site to validate the suitability of the land and to check the permeability of the soil to see which system would be most suitable and at what cost.

  • Can I build a septic tank anywhere?

    No, a septic tank must be installed in an area that takes into account space between residences, lakes, ditches, riparian protection bands, wells, etc. Then, the land must be surveyed to determine if a limiting layer is present and if it allows the installation of a system (ex. water table, rock, clay, etc.).

  • Does a septic tank last for life?

    No, when well-maintained, and when installed in soil that’s in good condition, it can last several years. However, periodic inspection and regular draining must be carried out. It is important to follow all recommendations. It is important to respect all the recommendations for the exterior maintenance of the system (grassing, avoiding compaction, etc.), as well as for what is placed in the septic tank (avoiding acids, water treatment waste, oils, etc.).

  • Can I install my surface or artesian well anywhere?

    No, whether it is a surface, artesian, or geothermal well, the well must respect the distances and setbacks mentioned in the Q2-R.35 “Water Withdrawal and Protection Regulation”.

  • Once your assessment is completed, what documents will you produce?

    Once the site has been assessed and the study of the soil has been completed, we produce the technical plans and list the requirements to obtain the installation permit from the municipality, usually, a technical estimate, plans, well and septic sections, and a particle size analysis, as performed by an accredited laboratory.

  • Can I hire the contractor of my own liking to do the work with your plans?

    Yes, as long as they have all the necessary certifications for the system to be installed. We have good business relationships with many contractors and can give you recommendations.

  • Once the work has been completed, what documents should I send to the municipality?

    We produce a certificate of compliance as well as an as-built plan of the location of the elements that you must submit to your municipality to close your permit application file.

  • Can I decide for myself to have the least expensive system installed on my property?

    No, only a professional in the field who is a member of the Ordre professionnel des technologues du Québec or the Ordre des ingénieurs du Québec can determine the type of system to install on a property.


    The Professional must respect the hierarchy of purifying elements from primary to advanced secondary or tertiary systems. However, the commonly named advanced secondary or tertiary systems sometimes take up less space and limit the footprint. 


    A discussion is therefore necessary in order to properly evaluate the client's needs. As a consultant, it is our duty to give the maximum amount of information on the different systems so that they can make the best decisions and choose what suits them best while respecting all the regulations.
