What is NOT a key factor in determining if a septic system is suitable for a property?

The suitability of a septic system for a property primarily hinges on factors related to the soil and environmental conditions that facilitate effective waste absorption and management. The soil's ability to absorb sewage effluent is crucial because it determines how well the treated wastewater can percolate and be filtered by the soil, which is vital to prevent contamination of groundwater and surface water.

The groundwater table is another key factor, as its depth can influence the effectiveness of a septic system. If the groundwater table is too high, it can lead to system failure by causing effluent pooling and insufficient treatment. Similarly, the slope of the land is important, as steep slopes can lead to runoff and erosion, impacting the septic system's functionality and the surrounding environment.

In contrast, the distance to electricity supply is not a critical factor in determining the suitability of a septic system. While electricity may be necessary for certain systems with pumps or alarms, it does not affect how well the septic system will function in terms of effluent absorption and treatment by the soil. Therefore, the proximity to an electricity supply does not play a direct role in evaluating whether a property's conditions are appropriate for a septic system.
