Humber/Ontario Real Estate Course 2 Exam Practice

A Class 5 system refers to a Holding Tank System. In this scenario, the contractor is informing Mr. and Mrs. Singh that the soil conditions and drainage on their property do not allow for a traditional septic system, so a holding tank system will be required. Holding tank systems store all wastewater on the property until it can be collected and properly disposed of at a designated location, which is often done by a licensed sewage hauler. This solution is necessary when septic systems are not feasible due to the soil composition or drainage issues.

Option A, a Septic System, is incorrect because the scenario explicitly states that a Class 5 system is required instead. Option B, a Grey Water System, is also incorrect as it is not relevant to the scenario provided, which specifically mentions a Class 5 system mandated by the municipality. Option D, a Municipal Sewer System, is incorrect because the scenario does not indicate that the property is connected to a municipal sewer system, but rather that a Class 5 system is required due to soil conditions and drainage concerns.
