What must be done to obtain final system approval when curtain drains are needed?

To obtain final system approval when curtain drains are needed, installing the curtain drain is essential. A curtain drain serves to redirect groundwater away from a septic system, preventing excess water from saturating the soil and interfering with the treatment process. By managing water levels, curtain drains help ensure the septic system functions properly, which is a critical factor in receiving final approval from local regulatory authorities.

The completion of this installation demonstrates compliance with necessary regulations and proves that the system includes adequate measures to protect its operation. Once the curtain drain is in place, the system can be assessed for its overall performance and effectiveness before being granted final approval. Other actions, such as waiting for local authority approval, conducting additional testing, or installing a new septic tank, may be necessary depending on other circumstances, but the specific requirement of installing the curtain drain is a definitive step toward achieving compliance and approval.
