What is the required separation distance from a septic tank to a retaining wall?

In Connecticut, the required separation distance from a septic tank to a retaining wall is set at 5 feet. This regulation is in place to ensure the structural integrity of both the septic system and the retaining wall while minimizing the impact of the septic system on surrounding structures. A smaller separation distance helps to facilitate maintenance and reduces the risk of any backflow or structural issues that could arise from inadequate spacing between the two. It's important for septic system designers and installers to adhere to this distance to ensure compliance with health and safety standards, as well as to promote proper functioning of the septic system in relation to nearby features like a retaining wall.
