What can extreme weather events indicate for OSSFs?

Extreme weather events, such as heavy rains, flooding, significant temperature fluctuations, or droughts, can greatly affect the performance and operation of On-Site Sewage Facilities (OSSFs). When such conditions occur, the systems may be subjected to stress beyond their normal operating parameters, leading to potential failures or the need for adjustments in management practices.

In scenarios of heavy rain or flooding, for example, the increased volume of water can overwhelm the system, potentially leading to backup, inadequate treatment of wastewater, or erosion of soil around the system components. The risks and strain on these systems emphasize the importance of increased inspections and maintenance responses to ensure their proper functioning.

Additionally, changes in soil conditions and water tables due to extreme weather can affect the absorption capabilities of the soil, requiring monitoring to adapt to these changing conditions. As such, the necessity for more frequent maintenance and monitoring during and after extreme weather events is crucial to maintaining the operational integrity of OSSFs.
