Septic Tanks

The Council undertakes assessment of sites and developments involving on-site wastewater management systems (traditionally septic tanks, but now incorporating a number of alternative technologies).

A Special Plumbing Permit constitutes an approval to use a system or device (e.g. a septic tank) and a plumbing permit is also required before installation can proceed.

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

  • a fixture located on a floor which is wholly or partly below ground level
  • a waste disposal unit
  • trade waste
  • drainage from a swimming pool
  • an inlet to a sewerage installation at a level which is lower than 150 mm above a declared drainage flood level for the land on which the sewerage installation is located
  • the retention of any plumbing product which does not comply with the Tasmanian Plumbing Code
  • the use of a product that does not comply with the Tasmanian Plumbing Code in a building of architectural or historical interest
  • the installation of an on-site wastewater management system in accordance with AS/NZS 1547:2000 on-site domestic-wastewater management
  • testable and registrable backflow prevention devices

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