Soluo steps

Topographical analysis (slope, distances, sensitive areas)

In Montérégie, topographical analysis is an essential step before any septic installation. The region is marked by diverse landscapes: agricultural plains, gentle hills and riparian zones along the Richelieu River or the Yamaska. At Soluo, we carefully study the slope of the terrain, the proximity of watercourses, artesian wells and wetland areas.

Percolation test to measure infiltration

The percolation test measures the rate at which water infiltrates into the soil. In Montérégie, this measurement is particularly important, as soils vary greatly from one locality to another: clayey on the agricultural lands of Saint-Hyacinthe, sandy towards Beloeil and Saint-Césaire, or even silty near the rivers.
Our technicians dig test pits at various depths to evaluate the ground’s capacity to absorb wastewater. This data directly influences the choice of septic system. A soil with slow infiltration might require, for example, a raised system, whereas a more draining soil will allow a conventional leach field.

Granulometric analysis (sand, clay, silt)

Granulometric analysis is a scientific stage of the soil test. It determines the proportion of sand, clay and silt in the soil. These data help understand the soil’s natural permeability and to design a durable system.
In Montérégie, where agricultural soils dominate, this analysis is crucial. A soil rich in clay, for example, can slow the evacuation of water, while a sandy soil may allow untreated effluent to pass too quickly. Thanks to this study, Soluo designs systems perfectly adapted to local realities, whether it’s a riverside residence in Saint-Denis-sur-Richelieu or a family farm in Saint-Césaire.

Detailed report submitted to the municipality

Once the analyses are completed, Soluo prepares a comprehensive report compliant with Regulation Q-2, r.22. This document, intended for your municipality, compiles all the results of the soil test, infiltration calculations and design recommendations.
In Montérégie, each RCM — whether Vallée-du-Richelieu, Haut-Richelieu or Rouville — may have specific requirements. Our reports are therefore tailored to each municipal context and greatly facilitate obtaining the septic installation permit. This report also serves as a reference when selling or modifying the system in the future.

Personalized advice on the types of possible systems

After the soil test, our experts guide you towards the septic system best suited to your land and lifestyle. In Montérégie, conditions vary so much that no single solution applies.
For a house on sandy ground near Beloeil, a traditional leach field is often sufficient. Conversely, a clay soil in Saint-Hyacinthe may require an advanced treatment system with additional filtration.
We also take into account the number of bedrooms and local environmental constraints. These personalized recommendations ensure the durability, compliance and performance of your system.

FAQ

How long does the test take?

In Montérégie, the timeframe for carrying out a complete soil test generally varies between 10 and 20 working days, depending on the municipality and the nature of the land. From the initial visit by our experts, whether in Saint-Jean-sur-Richelieu, Mont-Saint-Hilaire or Saint-Hyacinthe, you will already receive a clear idea of the solution suited to your property. The analyses and drafting of the report, required by local RCMs such as Rouville or La Vallée-du-Richelieu, then follow quickly to facilitate your municipal permit application.

Can a septic tank be installed without a test?

No. In Montérégie, the provincial regulation Q-2, r.22 requires that a soil test signed by a professional be submitted for any septic installation permit application. Whether you are in Beloeil, Saint-Hyacinthe or Chambly, your municipality will refuse an installation without a compliant characterization study. This step ensures that your system will be safe, durable and environmentally friendly, particularly in the agricultural and riverine areas typical of the region.

What systems are possible?

The varied soils of Montérégie — sandy, clayey or silty — determine the ideal septic system type. Depending on your land and regulatory requirements, our experts can recommend a traditional leach field or advanced treatment technologies such as Bionest, Ecoflo, Hydro-Kinetic or System O)). Each solution is chosen to ensure regulatory compliance and the protection of waterways such as the Richelieu River and the Yamaska.
