What is the main purpose of conducting a site evaluation before installing a septic system?

The primary reason for conducting a site evaluation before installing a septic system is to ensure that the location is suitable for effective wastewater treatment. During this evaluation, various factors are assessed, such as the soil's permeability, depth to groundwater, proximity to surface water, and the overall landscape and topography. This information is crucial because a septic system requires specific conditions to operate properly, including adequate drainage and the ability to treat wastewater effectively without contaminating surrounding environments.

When the site is not suitable, issues such as system failure, groundwater pollution, and health hazard risks can arise, leading to significant environmental concerns and financial repercussions. Therefore, making sure that the site can adequately handle the anticipated load from the septic system is essential for long-term functionality and public health.
