Rainwater is one of the best sources to harvest water for your home and garden stock. As we all know, there are a lot of rainwater harvesting systems today which give various benefits to make us easy getting water from rain. One of the best way to harvest rainwater is by using flat tanks.
What’s the differences between flat tank and conventional concrete cistern (or cylinder tank)? Flat tank only needs a low installation depth with 75 % less digging compared with a concrete cistern and no slope angle required. It means you can save more than 100 wheelbarrow loads of soil from harvesting rainwater in flat tank. While, the installation of conventional concrete cisterns needs an excavation of considerable depth and there will be more slope angles.
Another difference is the use of the appropriate machinery of conventional concrete cistern that can have an adverse effect on neighbouring sections of the garden. On the other hand, a flat tank is usually characterised by a particularly flat construction. This makes flat tank possible to be installed in an already existing garden, for example the ditch necessary for a 3,000 litre tank only needs to be 1 metre deep.
The flat tank is made of polyethylene which is groundwater resistant. Another advantage is that it’s very easy to be installed and needs very low maintenance. Only two people needed to install it with simple equipment because of its low weight. This flat tank can also be driven over by cars (up to 2.2 tonnes) and you even can install it under the garage or driveway. Tanks holding 1,500, 3,000, 5,000 or 7,000 litres are available as single tanks or as a complete system for the house and garden.
