What are mandatory water supply systems?

• In some states and territories there may be requirements for new buildings to include mandatory water supply systems. This would likely be due to drought conditions which require builders to install water saving systems such as rain-water tanks or grey water treatment plants.
• In Queensland there were state-wide laws requiring water supply installations that were repealed in 2013. However some local governments continue to require compliance with water-saving requirements.
• You should contact your local government to see whether they require new buildings to include water supply systems.
• Even if they do not you may voluntarily choose to install a water-saving supply system. If you choose this option any installation must comply with the health and safety standards found in the Queensland Development Code.
