Due to geographical dispersion of homes outside urban areas, the construction of waterworks, sewers or wastewater treatment plants is often impossible. Therefore, each property must possess its own autonomous drinking water supply system (well) and wastewater disposal system (septic tank and leaching field).
In order to address the lack of regulation, the provincial government adopted in 1981 the Regulation Respecting Wastewater Disposal Systems for Isolated Dwellings [Q-2, r. 22]. The Regulation dictates dimensions for drainfields and required minimum clearances. It also gives guidelines regarding the type of drainfield and the required installation depth depending on soil constraints. These guidelines must take into account the number of bedrooms and the flow of wastewater to be treated.
Wastewater treatment is usually done through the subsoil in place. Onsite wastewater management systems can only perform at their full capacity if soil conditions are optimal. Based on the permeable soil thickness, different types of systems may be suited for a single site.
Avizo Consulting offers you studies (percolation tests or soil testing) to determine the soil nature and permeability, as well as the bedrock and groundwater depths. We also offer you a full range of services such as:
- Onsite Wastewater System pre-purchase inspection;
- Leak testing;
