What is the minimum distance required from the distribution field to building foundations?

The minimum distance required from the distribution field to building foundations is established to ensure proper functioning of the on-site sewage facilities and to promote public health and safety. Setting a distance of 5 feet helps to prevent any potential contamination of the building's foundation by the effluent from the distribution field. This distance allows for the adequate absorption of the effluent into the surrounding soil, minimizing the risk of backflow or negative impacts on the building structure from moisture and sewage.

This standard distance is also part of a larger framework designed to avoid structural issues related to excess moisture or groundwater loading near foundations that could weaken or destabilize them over time. Such distance requirements contribute to the overall effectiveness and sustainability of sewage systems by maintaining appropriate separation between sewage activities and living spaces.
