With Detention tanks becoming a requirement, why not increase the capacity and make your detention tank a retention/detention tank. For example, if you are required to have a 4000 litre Detention, then go to a 7000 or 10,000 slim tank capacity allowing the extra litres to supply your household.

Selecting the Right Tank
- Choose the largest tank that will fit into your available area. Direct as much of your roof area as practical into your tank.
- Normal garden hosing can use up to 1000 litres per hour of water. A 5000 litre water tank will therefore provide around 5 hours of watering time. Make sure capacity of your tank will suit your water use requirements.
- One square metre of roof area will provide one litre of water for every millimetre of rain. Maximising the roof area feeding to your tank is the best way to ensure you collect as much water as possible.
- Be aware that every 1000 litres of water in your tank is one tonne of mass. Considering the location of your tank, and be sure not to place the tank in an area with unstable ground or too close to existing house footings.
- Remember that you will need to access the leaf strainer to clean out leaves. This may be a consideration when deciding the height and location of your tank
