Most in-ground tanks and tanks above a certain dimension require building approval. In some instances, a building certifier must verify that the installation is structurally sound or Brisbane City Council may need to approve the tank location.
All pipes and fittings connecting the rainwater tank to your roof, household fixtures and the stormwater system should be done in accordance with plumbing and building standards. A plumbing inspection will be required if the tank is connected for internal uses.
Tank overflow should be properly managed to prevent uncontrolled stormwater discharge that could result in flooding and damage downstream.
Plumbing approval is required for any internal connection, including but not limited to:

Reduced rear and side boundary clearances will apply for narrow blocks and height restrictions for corner blocks.
