Property owners of homes not connected to a public drain are required to provide and maintain their own on-site, below ground level, wastewater/sewage treatment system.
These systems - septic tanks - should be regularly maintained and cleaned by a registered septic tank cleaning contractor.
Building consent is required by the property owner before a septic tank can be installed. This is to ensure that the tank meets the standards for building, environment and public health and safety.
If your septic tank fails contact a septic tank cleaning contractor in the first instant. If your septic tank fails and also discharges sewage you are required to notify the Council's Environmental Health Division.
