What happens if the soils have absorption rates greater than seventy-five minutes per inch?

When the absorption rates of soils exceed seventy-five minutes per inch, they are deemed unsuitable for conventional sewage disposal systems. This standard is set because conventional septic systems rely on the ability of the soil to absorb and filter wastewater efficiently. If the absorption rate is too slow, it can lead to problems such as surface ponding, system backup, or contamination of nearby water sources.

In the context of septic system installation, soil absorption rates are critical for determining the appropriate type of disposal system. Soils with rapid absorption rates may support conventional systems, while slow rates, like those greater than seventy-five minutes per inch, hinder effective wastewater treatment. As a result, alternative systems or more advanced treatment solutions are typically required to ensure proper waste management and environmental protection.
