Tank sizing and Water Calculators

  • What information do I need from my council?
    Your Council or Water Authority can provide you with information on what rebates you are entitled to and what the building, health and planning requirements are in your area.
  • What type of tank should I get?
    Water tanks can be round or semi-oval (slimline) shaped. Slimline tanks are best where you do not have a lot of space. Round tanks are ideal for holding greater amounts of water as they are cheaper per litre.Make sure the dimensions of the tank suite the proposed site and the tank is lower than your downpipes. There are also tanks specifically designed to be installed underground saving even more valuable space you should first contact your enter shop prior to ordering these as to soil suitability and check there are no services in the vicinity of the proposed excavation.
  • Will my tank match my house? 
    Polyethylene is available in a range of colours that have been matched to leading housing materials including the COLORBOND™  range of colours.
  • What accessories do I need?
    In most instances water tanks require fittings to connect to the roof runoff and household plumbing. It is worth purchasing quality fittings for your tank as this will ensure that there are no unnecessary problems. Other valuable accessories include leaf strainers, brass fittings, roof mesh, overflow units and water diverters.

How much water do I use? How much can I save?

Try the different sample options at  ACT Water Efficiency Calculator to find out just how water efficient your household really is, and where you could make big savings 

In general, around 20-30 per cent of household water is used in the garden. Through water efficient gardening practices such as reducing lawn areas, mulching, drip irrigation and water wise plants, you can dramatically reduce your water consumption in the garden.

Likewise, household appliances such as washing machines, dishwashers, toilets and showers can use a lot of water. By checking the water efficiency rating when you next buy an appliance you can help save water, and save money on your water and electricity bills.  From 1 July 2006, a new national, compulsory  Water Efficiency Labeling and Standards (WELS) scheme    replaced the previous voluntary 'AAAAA' labeling scheme.
