What is the primary function of a curtain drain in a septic system?

• A. To collect effluent
• B. To redirect groundwater
• C. To filter solid waste
• D. To improve drainage

Answer: (D)

The primary function of a curtain drain in a septic system is to improve drainage. Curtain drains, also known as trench drains or French drains, are designed to intercept and redirect excess groundwater away from septic system components. By managing water flow and reducing the saturation of soil in and around the septic system, curtain drains help prevent flooding of the leach field, ensuring that there is sufficient capacity for the septic system to function correctly. This enhanced drainage capability is crucial because excessive groundwater can lead to reduced treatment efficiency of the effluent in the leach field and can cause septic system failure. This is why a curtain drain plays an important role in maintaining the performance and longevity of the septic system by creating a more stable environment for the treatment and disposal of wastewater.
