You might have read online or even heard people say that one of the best ways to cut down on your energy bills was by making use of solar and other renewable energy sources. In a similar vein, you might have heard or seen advice that the best way to save up on water bills is through installing a rainwater storage tanks. If that advice has prompted you into a search for a rainwater tank, consider the following pointers first:
The size – one of the defining differences between the many rainwater tanks for sale is the size of the tank. Rather than relying on outsider opinions, it is important to evaluate the capacity you yourself are looking for when it comes to the size of the tank. You should keep in mind that the decision should be largely based on where you are planning to store your tank, as well as on the needs of your home when it comes to water usage. For example, the larger varieties of rainwater tanks are often stored underground, well-hidden from sight, but they are quite expensive; on the other hand, you can achieve a near-similar degree of secrecy with under-deck tank varieties, which will be cheaper but also significantly smaller. These are not the only options, of course, so make sure to look around.
Potable or not? – A good potable tank is basically a water storage tank that provides drinking water, whereas a non-potable water container is not recommended as a drinking water source. Generally, your average rainwater is not potable (at least, it used to be in the past, but the increasing concentrations of noxious gases in the atmosphere has increased the pH levels of rainwater), which means that if you want to drink it, you will have to buy the more expensive, potable tanks. On the other hand, if you are planning to wash your car or water your garden with the rainwater, a non-potable variety will suffice.
Catchment area – the technical details of the installation of the rainwater tank are often left to the professionals, but it is good to be aware of what goes on. The catchment area basically refers to the area which will serve to collect the rainwater that will be sent to your tank. Usually, you want to use the higher, wide and gently sloping surfaces as catchment areas due to the fact that they allow for greater harvesting of rainwater. As you might imagine, the roof of a house is usually the best candidate for the position. The fact is that the area of the catchment area will largely define the volume of water your tank will get (in addition to the frequency of rain in your locality), so it plays an important role in deciding how much money you can actually save with a rainwater tank.
