What is the minimum distance required between standard drainfield excavations?

The minimum distance required between standard drainfield excavations is three feet. This distance is crucial to ensure proper separation between different sites of leach lines or drainfields, which helps in the effective functioning of the wastewater treatment system. Adequate spacing minimizes the risk of interference between the effluent being treated at one site and the effluent from another, thereby preventing potential contamination and ensuring that each system operates within its intended parameters.

Having three feet of space facilitates proper infiltration of wastewater into the surrounding soil and helps in maintaining the integrity of the drainage systems. This spacing is based on guidelines which consider soil absorption capacities and the need to prevent overload on any single portion of the drainfield, thereby promoting a healthy and efficient septic system.
