Rainwater tank is the ideal way to save rain water and use it later in order to minimize the water restriction in your home. Of course this water is not cleaned to be used in kitchen for cooking or for drinking but you still can use it in many different places. For example, you can use this rain water for gardening or in washrooms or while you are washing clothes. So if you live in an area where you face problem of water and you have enough rains, you must have rainwater tanks in your home.
There are few things which you need to keep in mind while buying a rainwater tank. These points are mentioned below:
You need to make sure the size of the tank which depends on two things. You should buy a big rainwater tank if there is too much rain in your area and your water usage is too much. If the use of water is less in your home or there is less rain, there is no point of buying a rainwater tank of really big size. If you are facing a scarcity of water in your area, no one can tell you the importance of water but you. You will not be able to use this water in kitchen or for any cleaning purposes but you can use it to solve many other water problems like in gardens and in toilets.
The cost of rainwater tank is usually not that much and you can afford it. They are normally made up of plastic material and you can place them in backyard or garden. It is not necessary to buy a rainwater tank from market, you can use any old water tub or water tank for this purpose. Before you go out shopping for the rainwater tank, you must know where you are going to place it in your home. It is better to measure that space with a measuring tape and buy a water tank of only that size to avoid any trouble in future.
Some people also use rainwater for drinking purposes but that will only be made possible if the water is properly filtered. Though rain water is pure but it gets contaminated when it gets interacted with the environment and specially the tank. Special filtration let it remove pathogens from water but still is not good enough to drink. People in desert areas and rural areas drink this rain water after some filtration but still it is not preferred to drink.
As far as the material of rainwater tanks is concerned, usually plastic is considered as the best option. Plastic tank is easy to be moved from one place to another but if you are not planning to move it from one place to another, you can buy a rainwater tank made up of galvanized steel and concrete. You can save lots of rain water with the help of rainwater tank and use it later to wash your car or clothes or use them to flush toilets.
