How to plan my project?

To begin with, any request for a permit to build a septic system must have a site analysis carried out by a technologist or an engineer, known as a “designer” in this market.

This is your first step, whether you’re building a new home or upgrading an existing system. A site analysis will tell you what type of technology you can consider.

Contact one of our experts for advice on finding a “designer” in your area.

Project stages

Once you’ve shared the results of the site study, your “designer” is required to give you an overview of the various brands of technology available with a list of advantages and disadvantages for each. This is when you should start your own research. You can research the type of technology that is indicated on your site survey, for example ‘advanced secondary treatment.
