What is the center to center spacing requirement on all leach fields?

The correct center-to-center spacing requirement for leach fields is based on guidelines that ensure adequate separation between adjacent septic system trenches to promote proper functioning and prevent contamination. A spacing of 7 feet allows for sufficient soil absorption and ensures that each leach line functions independently without negatively impacting the others. This distance also helps to reduce the risk of hydraulic overload of the groundwater as it allows for proper drainage and aeration around each leach line.

This spacing requirement is critical to maintain the efficiency of the septic system, ensuring that effluent can be adequately treated by the soil environment, promoting a healthier groundwater ecosystem. The other options represent distances that are either too small, which could lead to system failures, or not aligned with the current regulatory standards in Connecticut.
