Humber/Ontario Real Estate Course 4 Exam Practice

For a property with unfit soil percolation for a septic system, what is a viable solution?

1. Install a grey water system.

2. Set up a septic tank system with a filter bed.

3. Install a raised bed septic tank system.

4. Set up a conventional septic system.

5. Ensure the installation of an advanced treatment system.

6. Improve existing soil quality for better percolation.

The correct answer is: Install a raised bed septic tank system.

Installing a raised bed septic tank system is a viable solution for properties with unfit soil percolation. This type of system involves constructing an elevated area where the septic system is installed, allowing for adequate drainage even when the native soil lacks the necessary percolation capacity. The raised bed ensures that effluent can be effectively treated before it infiltrates into the surrounding environment, making it suitable for challenging soil conditions. Other options might work under certain circumstances, but they may not directly address the issue of inadequate soil percolation. For instance, a conventional septic system relies on the soil's ability to absorb effluent, which wouldn’t be effective in this scenario. Setting up an advanced treatment system could potentially improve effluent quality but may still require some degree of suitable soil for final absorption unless designed to mitigate existing soil limitations. Improving soil quality might be a longer-term solution but may not be practical or cost-effective for immediate needs.
