Any residential development on a site not serviced by a sewer system must rely on some form of onsite waste disposal. In many instances it will be the suitability of the site for waste disposal which will determine if the site is capable of being developed.
When purchasing a vacant property that is not serviced by a Council sewer, it is strongly recommended that you satisfy yourself that some form of onsite waste disposal is suitable to your land size and plans for the property is achievable.
In the past a Septic Tank Permit was required to be issued by Council, this covers all types of onsite treatment including composting toilets and domestic treatment plants.
An onsite waste disposal system usually comprises of two parts, the treatment portion such as a septic tank, composting unit etc, and disposal of the treated waste.
Under the Tasmanian Plumbing Code the treatment unit must be accredited for use in this State. Some systems may be used Interstate or Overseas, however to be used in Tasmania it is necessary for the unit to be tested under our conditions.
The accreditation of waste treatment systems is managed by the Department of Infrastructure, Energy and Resources.
