• What sizes are available?

    Thintanks™ are available in three sizes currently, the 1000 litre, 2000 litre, 3000 litre and 4000 litre rainwater tank. They can all be installed as either a single water tank or in multiples of any number of tanks. Thintanks™ are ideal to join inline along boundaries, holding significant water storage without impinging on the backyard of a property, providing a pleasing fence like appearance.

  • How Much Do These Rainwater Tanks Cost?

    Due to the large perimeter : volume ratio and added thickness required structurally there is a large increase in material weight. The cost is dearer due to the increase in material usage. However, Thintanks™ are much easier to transport and easy to install. We recommend getting a Supply and Installation Quote from a local Thintanks™ dealer.

  • What Colours Are Available?

    Thintanks™ can currently provide a choice of 5 colours.

  • Can I Guarantee Constant Water Supply?

    This question is in relation to supplying water to a toilet and or laundry. Yes, Thintanks™ can be connected to the residence with a three way automatic valve that switches to mains water when the water tank has insufficient water to service those areas of a property.

  • What Size Tank Should We Install To Eliminate Or Greatly Reduce The Use Of Mains Water For Our Toilet And Laundry.

    Factors for selecting the right volume tank for my residence depends on.
    1. Roof collecting area of the residence.
    2. Number of people residing in the residence.
    3. Residence location based of rainfall in Capital cities.

  • I Have A Sloping Block, Can I Still Install Multiple Water Tanks?

    Yes, providing you place the inlet and overflow pipe at the highest level. The water must flow downhill into each tank and the overflow exits at the highest point in the multiple tanks. Install air release values in each tank that is downhill from the inlet. Discuss such installation details with your qualified installer who must be aware of the slope prior to ordering tanks. Air release values are required and the top entries manufactured to suit.

  • Can You Tell Me What Maintenance Is Required?

    Rainwater storage systems require very little maintenance provided they are correctly installed. Typical maintenance requirements include: Cleaning of the first flush device every 3-6 months Removing leaf debris from gutters and roofs every 3-6 months Checking insect screens and other potential mosquito entry points at the onset of warm weather each year Ensuring that water is not pooling in the vicinity of your Thintank™ Checking sediment Levels every two years Rainwater brings DIRT from both the roof and also the atmosphere as the rain falls. A good percentage of this dirt can be diverted from your Thintank™ by redirecting the first 70 litres to waste. First flush systems can be installed at minimum cost and will reduce the need to clean the inside of your Thintank™ Cleaning inside any rainwater tank is best carried out by your installer or local plumber and is done when the tank is nearly empty. Each Thintank™ is to be cleaned individually, with the dirty water being firstly recycled into the tank, providing as much agitation as possible to suspend the dirt into the circulating water and thereafter redirect the sludge to waste. The aim is to remove as much sludge from the tank with a minimum loss of water.
