All About Our Concrete Tank Range

When it comes to water tanks, we understand that you have different water needs and that is why we make sure we provide a wide range of concrete tanks. Our tanks range from 3,800 to 11,500 litres and where capacities that are not covered in the range are needed, we interconnect two or more tanks. We are totally committed to making sure you have enough harvested water to do everything you need to do, including flushing your toilet, hosing your driveway, or even watering your garden. Here is the list of concrete tanks that we offer to help in water harvesting.

 

3,800 litre Squat tank

This is the smallest in our range of water tanks. It is built in a shape that suits rocky terrain, where excavation could be a somewhat difficult endeavour. The entire tank design means that only a shallow hole is required which brings down the costs of excavation. This type of tank is suitable for smaller households with less than five people, where the water is used for household use only.

 

6,100 litre medium tank

This is the medium sized concrete water tank in our range and is designed to suit a variety of geographical profiles. It is the perfect marriage between size and capacity making it a desired compromise for most households. It allows you to enjoy all the benefits that come with harvesting rainwater, while working with the space you have. Like the name suggests, this tank is excellent for medium sized households with normal water use.

 

10,000 litre tall tank

With our tall tanks, we have officially entered into our range of larger tanks. These are useful in water harvesting especially in areas where the rainfall during winter is substantial. This being our second largest tank, it is ideal for places where long periods of dryness necessitate collection of a lot of water during the spells of rain.

 

11,500 litre high tank

This is the largest tank in our range. This tank was designed with specific councils in mind since they require a larger capacity for water retention, for instance, the Palarang area. This is recommended for households that would benefit from using a large amount of harvested water for everyday use including for the toilet to water gardens and flower beds, to wash the car, and hose down the driveway.

 

Bushfire Resistant tanks

Australia is known the world over for its devastating wildfires. This is why we have in our range of tanks, a fire-resistant option. These are tanks that are suitable in areas where bushfires are a danger, such as Sydney and Canberra. We have come up with a tank that puts together both retention and detection so that it can be used as an additional source of water to fight fires and save your home from damage.

How far into the ground can you place a water tank?

Some people, when they buy or have a water tank installed would like to bury their tank, this can be done to reduce the height of the tank – especially if it is blocking the view, or to hide it away completely. Steel tanks will corrode if buried, so, for that reason, they are best left above ground, however concrete in ground water tanks can be buried, as can poly water tanks.

When it comes to poly tanks it’s important that you just don’t bury *any* poly tank. Those standard *above ground* tanks have not been designed to withstand the pressures of the earth and if they are not properly supported they can collapse due to the outside pressure. Having said that you can partially bury a poly water tank.

Before you start burying an in-ground water tank it’s important to get the advice of an engineer as the desired depth, type of soils and the location needs to be evaluated by an expert before partially burying your tank. This is to ensure foundations are not eroded and your tank will be properly supported.

It’s best not to bury a poly tank more than 1 metre into the ground and your hole should be 300mm or 12 inches wider than the diameter of the base of your water tank. If you plan to bury two tanks you need to dig two separate holes. You must prepare the foundations for your tank as normal, that is it must still sit on a compact, level and flat base. Bases can include concrete, brick, gravel or solid dolomite between 300mm and 400mm deep.

Ensure that the surrounding soil left in the walls of the hole are solid if there is any major water seepage into the hole from the surrounding soil the site will not be suitable

Once the tank has been placed on the base, fill your tank with water then backfill the hole with cement powder and crusher dust compact just 75 to 100mm at a time.

It’s important that tanks be buried into the ground only half way up its wall height and that your outlet that picks up from the tank comes through the tank roof, or alternate plumbing from the base outlet is needed. If there are 2 x 90mm inlets coming into the tank, you will need at least 2 x 90mm overflow pipes. Overflow must be piped away from the tank

You can bury your poly tank completely – you just have to buy a tank that has been designed to be an in-ground water tank. In-ground tanks are designed to provide you with a wholly hidden water storage solution, they are suitable for installation under a driveway, pathway or garden.
