What is the impact of seasonal changes on OSSF?

Seasonal changes significantly impact On-Site Sewage Facilities (OSSF) due to variations in rainfall and temperature, which directly influence soil absorption rates and overall system functionality. During periods of heavy rainfall, the soil can become saturated, which may hinder its ability to effectively absorb effluent from the OSSF. This saturation can lead to surface runoff or even system backup, compromising the treatment process. Conversely, in dry conditions, the soil may absorb effluent more rapidly, potentially affecting the concentration and breakdown of contaminants. Additionally, temperature fluctuations can affect microbial activity in the soil, thereby impacting the efficiency of the treatment process. It’s crucial for system designers and operators to understand these seasonal dynamics to ensure adequate system performance and prevent potential environmental issues.
