Septic Tanks

If you are planning on building on land that is not supplied with a reticulated sewerage system you will need to apply for a Plumbing Permit to demonstrate how you are going to treat your waste water.  Plumbing Permits are a requirement under the Building Act 2016 and the Building Regulations 2016 and therefore councils Environmental Health Officers undertake the assessment all developments which involve on-site wastewater management systems (i.e. septic tanks). 

A Plumbing Permit is needed in a number of circumstances such as:

  • the installation of an on-site wastewater management system in accordance with AS/NZS 1547 on-site domestic-wastewater management
  • drainage from a swimming pool
  • the use of a product that does not comply with the Plumbing Code Australia in a building of architectural or historical interest

All proposed on-site waste water systems are required to be approved by Workplace Standards.

On-site disposal systems must be maintained according to the Plumbing Permit. To obtain a Plumbing Permit you must make application to the Council with the required documentation. 

For most existing dwellings with on-site waste water systems Council keeps detailed drainage plans to assist in locating on-site wastewater drainage system.
