Water savings targets

Rainwater tank laws pre-February 2013

Building development applications lodged for the construction of new class 1 buildings (houses, townhouses, terrace houses and villas) before 1 February 2013 in Queensland were required to meet mandatory water savings targets.
 

The targets were achieved through a number of options including:

  • household rainwater tanks
  • dual reticulation
  • communal rainwater tanks
  • stormwater re-use
  • an approved greywater treatment plant.

The targets applied to all local government areas in Queensland. Where rainwater tanks were used to meet the water savings targets local government could:

  • accept the minimum requirements set out in QDC 4.2
  • specify an increased minimum in a local government planning instrument for tank storage capacities, roof catchment areas or other household fixture connections.

Rainwater tank requirements

When a rainwater tank is used to meet the new targets, the minimum capacity and connection standards specified for tank installation are:

  • single, detached houses had to install a rainwater tank with a minimum 5,000 litres capacity
  • non-detached houses (such as terrace houses, townhouses and semi-detached houses) had to install a rainwater tank with a minimum 3,000 litre capacity
  • all rainwater tanks had to receive rainfall from at least half of the available roof catchment area or 100 square metres, whichever is lesser
  • tanks to be connected for internal use to all toilet cisterns, washing machine cold water taps and for external use to at least one tap
  • internal fixtures supplied from a rainwater tank had a continuous supply of water, via an automatic switching device or a trickle top up system.

Exemptions

Under the previous requirements (pre 1 February 2013) local governments were able to apply the Minister for an exemption from water savings targets where:

The Minister granted the following local governments an exemption under QDC 4.2:

Building development applications made in these local government areas before 1 February 2013 did not have to comply with the water savings targets in QDC 4.2 or the requirements of QDC 4.3. For building development applications made on or after 1 February 2013 the water savings targets no longer apply in any local government area (unless that local government has been approved to opt-in to the requirements of the revised Queensland Development Code Part 4.2 – Rainwater tanks and other supplementary water supply systems (for residential – class 1, 2 and 10 - buildings) and Part 4.3 – Supplementary water sources – commercial buildings (for commercial and industrial - class 3-9 - buildings).
