Why is it important to have a site evaluation before installing a septic system?

Having a site evaluation before installing a septic system is crucial because it ensures that the soil and drainage characteristics are suitable for the proper functioning of the system. During the site evaluation, various factors are assessed, such as soil percolation rates, soil texture, and depth to the water table. This information helps determine whether the site can effectively absorb and treat wastewater.

If the soil is not capable of handling wastewater due to issues like poor drainage, high groundwater levels, or certain soil types that retain water, it could lead to system failures, contamination of groundwater, and environmental hazards. The evaluation ensures that the septic system is designed to function optimally given the specific site conditions, thereby enhancing its longevity and reliability while protecting public health and the environment.
