For Guidance OnlyLocating the Septic Tanks & Sewage PlantMinimum distances for locating Sewage Plant are set out below. These are minimum distances only; the unit should in fact be located as far away as is practically possible. However, when locating the unit, consideration should be given to allow adequate access forthe vacuum tanker. The unit should be located not nearer than 7m from any other dwelling as set out in the wastewater treatment manual.
