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 involves an approval to use a system or device (e.g. a septic tank). A plumbing permit is also required before installation can proceed.
A Special Plumbing Permit is needed in the following circumstances:
- 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 submit an application to the Council with the required documentation.
