What is the minimum square footage of a buried sand filter per bedroom in a septic system?

The minimum square footage of a buried sand filter per bedroom in a septic system is set at 200 square feet. This standard is important in ensuring that the sand filter has adequate surface area to effectively treat the effluent from the septic system. Proper treatment capacity is necessary for maintaining sanitary conditions and protecting public health and the environment.

When designing a septic system, each bedroom typically requires a certain amount of space allocated for the sand filter. This allocation allows for sufficient absorption and filtration of effluent, which is crucial for minimizing the potential for system failure and environmental contamination. The regulation specifying 200 square feet per bedroom helps to standardize installations and promote system longevity and functionality. By adhering to this requirement, contractors ensure that the system will perform optimally and meet regulatory standards.
