Why should rainwater runoff be controlled around an OSSF?

Controlling rainwater runoff around an On-Site Sewage Facility (OSSF) is essential because excess water can overwhelm the treatment unit. When rainwater enters the system, it increases the volume of water that the treatment unit must handle. This can lead to reduced effectiveness of the treatment process, as the system may become inundated and unable to properly treat sewage. Overloading can result in untreated sewage being discharged into the environment, causing potential health hazards and environmental contamination.

Additionally, managing rainwater runoff helps maintain the balance necessary for the OSSF to function optimally. By preventing excessive water from saturating the system, the treatment processes can occur more efficiently, ensuring that the treated effluent meets health and environmental standards.
