Install a rainwater tank and save both water and money. A rainwater tank provides you with the following benefits:
High quality tank water is dependant on the owner’s maintenance of a healthy tank. Proper maintenance involves the cleaning of gutters and downpipes and checking for mosquito and vermin control. Tank installation could include a “first flush” system to divert the initial scour of dirty rainwater away from the tank.
If water is only to be used for non-drinking purposes, such as in the washing machine or toilet, then it is unlikely that any treatment will be required, although filtering does limit some contamination. If water is to be provided for other household uses that involve contact with humans, such as drinking, showering or cooking, additional treatment should be considered; potentially ultra-violet disinfection.
When installing a rainwater tank attaching several simple devices may assist in keeping the tank water quality in reasonable condition.
Gutter guards prevent leaf litter entering the tank
If leaf litter enters the gutter, this debris may accumulate and block the rainhead or inlet screen causing uncontrolled overflow and reduce the amount of rainwater collected.
A building approval is required for rainwater tanks where one or more of the following criteria applies:
In other circumstances you do not require building approval from Council. However, you will need to follow guidelines on related issues such as where to locate the tank and how to discharge water overflow.
When retrofitting to an older existing home there are several things you need to consider such as what size tank and how much water will be collected.
What size tank should I buy?
When planning to install a rainwater tank, you should determine:
Stormwater from roofed areas and overflow from any rainwater tanks is to be collected and discharged using one or more of the following techniques.
