What does organic content in cover material need to be limited to?

The correct limitation for organic content in cover material is no more than 10%. This is essential because excessive organic material can lead to problems in the septic system, such as clogging and insufficient filtration. Organic materials can decompose in the soil, potentially creating a layer of muck that impairs the bacteria's ability to break down waste effectively. Maintaining a lower percentage of organic content ensures that the cover material remains stable and functions properly, promoting efficient wastewater treatment. This guideline helps to ensure the longevity and effectiveness of the septic system, minimizing maintenance issues and environmental impact.
