What is the minimum setback distance for subsurface drainage absorption lines when upgrading or downgrading?

1. 5 feet

2. 10 feet

3. 20 feet

4. 30 feet

The correct answer is: 10 feet

The minimum setback distance for subsurface drainage absorption lines when upgrading or downgrading is 10 feet. This distance is established to ensure that the drainage system functions effectively while minimizing the risk of contamination and maintaining water quality. A setback of 10 feet helps to provide a buffer between the subsurface absorption lines and other structures or features, promoting proper drainage and reducing the potential for adverse environmental impacts. Adhering to this minimum distance is crucial for the health of the surrounding land and groundwater systems, as it allows for appropriate filtration and absorption of wastewater. In jurisdictions where regulations apply, this setback ensures compliance with local ordinances designed to protect both public health and the environment. Proper understanding and application of these distances are vital for successful installations and upgrades of drainage systems.
