What is the required setback distance from the edge of a drain field for up-gradient foundation drains?

The correct requirement for the setback distance from the edge of a drain field for up-gradient foundation drains is indeed 10 feet. This setback is crucial in preventing potential contamination of the drain field and ensuring that the drainage systems function properly without interference.

Foundation drains are designed to manage groundwater around a building, redirecting it away to prevent water from accumulating near the foundation. If these drains are located too close to the drain field, there is a risk that they may draw water from the drain field or alter the natural flow of water, leading to issues such as flooding or saturation of the drain field, which can compromise its effectiveness.

Maintaining this 10-foot distance helps ensure that the groundwater management system operates efficiently while safeguarding the integrity of the septic system. Having this required setback in place protects both public health and the environment, delivering on best practices for septic system installations.
