How can excessive rainwater runoff impact a septic system?

Excessive rainwater runoff can significantly impact a septic system by saturating the surrounding soil. When the ground becomes overly saturated, it can hinder the proper drainage of wastewater from the septic system. This saturation can lead to a rise in the water table, which impedes the system's ability to treat and disperse effluent effectively. As a result, the septic system may experience backups, slow drainage, or even failures, which can lead to more severe environmental issues and costly repairs. Understanding the implications of rainwater on septic systems emphasizes the importance of proper site assessment and management practices to mitigate runoff and protect system functionality.
