What is the main purpose of a curtain drain on a septic site?

The main purpose of a curtain drain on a septic site is to direct water away from septic systems. Curtain drains are specifically designed to manage groundwater and surface water, preventing excess water from pooling in the area surrounding the septic system. This is crucial because excessive water can interfere with the proper treatment of wastewater in the septic system and increase the risk of system failure.

By effectively redirecting water away from the septic area, the curtain drain helps maintain the necessary conditions for the septic system to function optimally. It protects the integrity of the system and ensures that the soil remains capable of filtering and absorbing wastewater appropriately. Thus, the effectiveness of both the septic system and the curtain drain relies on their proper installation and placement to ensure they complement each other in managing site drainage.
