How can seasonal weather impact the function of a septic system?

Heavy rains can significantly impact the function of a septic system by saturating the drain fields. When the ground becomes overly saturated with water, it can hinder the proper absorption of effluent into the soil. Septic systems rely on the soil to treat and absorb wastewater; therefore, if the soil is already saturated from heavy rainfall, it can lead to backflow or surface discharge, resulting in system failure and potential environmental hazards.

During heavy rain events, the water table may rise, and the excess water can fill the space in the soil where the septic effluent would normally go. This lack of capacity can lead to pump failures or the inability of the system to treat wastewater effectively. It is crucial for installers and homeowners to be aware of these potential impacts, especially in regions prone to heavy precipitation, to ensure proper system maintenance and functionality.
