When buying a water tank, you should keep in mind. When buying a poly or plastic tank, check if the tank is Ultra-Violet Radiation protected and if it is made of Food Grade material. If the tank’s diameter is large, then ensure that it has an internal support pole to keep its shape intact.
Position of the Rain Water Tank
You can install the rain water tank either above your house or underground below your house. An underground tank has a few advantages though benefits of an above ground tank are higher. An underground tank is resistant to atmospheric variations where as an above ground tank should be strong enough to bear the climatic changes.
You can install an underground water tank if you don’t have enough space to place it above ground. It needs extra protection and plumbing like flood water guards and pumps for proper functioning. Above ground rain water tank need lesser attachments for proper functioning.
The necessary regulators include level detector, water filters etc. If you use the water directly in washing machines etc, you need to maintain a particular level of water at all times. For this you need a top-up system of above ground rain water tank.
Material used for manufacturing of various rain water tanks
The size, shape and quality of rain water tanks more or less remain the same though the manufacturer may be different. This is because they have to produce water tanks according to the set standards.
The different types of Rainwater Tanks available in the market include polyethylene tanks, metal tanks, fibre glass tanks and concrete tanks.
The first three types are manufactured and delivered as a complete unit. Concrete tanks are built during construction itself. All can be used as below as well as above ground tanks.
Fibre glass is costlier than the rest but it has the advantage of not getting rusted and not succumbing to algal growth. You can go for a particular material rain water tank based on your budget and requirements.
