Septic Tank Tips for Auckland

Auckland's rural-residential areas on Waiheke Island, the Rodney District, and Franklin are largely on septic — Auckland Council requires resource consent for most new systems

Auckland Unitary Plan rules on effluent setback distances are strict — particularly near waterbodies and in Significant Ecological Areas — confirm setback compliance before installation

Auckland's high rainfall and clay soils in many peri-urban areas can cause drainfield failure — a soil investigation is essential before any new installation or drainfield replacement
