ExEcution OF WORK 2.4

Course Content : Execution of Work 2.4

The person who succeeds the exam may act as the guarantor for the license in Execution of Construction Work for all construction activities included in Subclass 2.4 (Contractor – Septic Tanks).

The exam for subclass 2.4, Contractor – Septic tanks, covers the following topics:

• Waste water disposal systems regulation
• Remedies available to municipalities to enforce the regulation
• Legislative, normative, and regulatory frameworks
• Different types of systems and their maintenance
• System location and setbacks
• Primary, secondary, and tertiary treatment systems
• Construction standards
• Penalties & more.

The training designed for contractors in subcategory 2.4 provides a thorough and structured understanding of the technical and regulatory realities associated with autonomous wastewater treatment systems. Participants learn to identify the specific characteristics of septic installations, including soil types, permeability levels, regulatory setback distances, and environmental requirements. Strong emphasis is placed on analyzing site conditions, an essential step in ensuring system compliance and preventing contamination risks.

The course also highlights essential quality‑control practices, such as component inspection, verification of soil absorption capacity, evaluation of secondary and tertiary system performance, and recommended maintenance procedures. Contractors must be able to detect signs of system failure, assess related risks, and implement corrective actions that align with current regulatory standards.

Another major component of the training focuses on coordination with municipalities and public health authorities. Septic system work often requires specific permits, compliance analyses, mandatory inspections, and continuous communication with municipal services. Candidates learn how to prepare the required documentation, comply with the requirements of Regulation Q‑2, r.22, and plan interventions in a way that minimizes environmental impacts and disturbances to neighboring properties.

Ultimately, this training equips contractors in subcategory 2.4 with the advanced skills needed to install, maintain, and oversee septic systems that are compliant, safe, and durable, while meeting Québec’s rigorous regulatory and environmental standards.

The training also deepens the contractor’s understanding of how environmental and site‑specific factors influence the performance of autonomous wastewater treatment systems. Participants explore how seasonal variations, groundwater fluctuations, vegetation, and surrounding land use can affect system efficiency and long‑term durability. The course further examines best practices for excavation, backfilling, drainage management, and the protection of sensitive areas during installation. By integrating these practical considerations with regulatory knowledge, future guarantors gain the ability to plan and execute septic system work with greater precision, ensuring both compliance and optimal system performance over time.
