Rainwater has been established as a viable source of water for both urban and rural communities, if the right measures are applied. It requires only an adequate system to be put in place to ensure that the collection and the rest of the processes required to make the water safe for consumption, is put in place. This system usually involves components such as, a storage tank and an appropriate filter system for purifying the water sufficiently, and distributing it as well.
Of all the components in the rainwater harvesting system, the most expensive and even most critical is the storage system. They come in various types and made from various materials. A knowledge of what materials were used can help a customer choose from the various rainwater storage systems available for purchase in the market. There is also the need to consider other factors during the selection process for which storage system to use; factors such as, amount of rainwater available, how much water is needed, estimated duration of periods without rain, and surely, how much you have to spend.
Now, here are descriptions about the various major materials used for making storage systems. Metal tanks- usually made of steel that is galvanized or currugated to improve resistance to rust and such outcomes. They are usually coated on the inside with epoxy paint, or laced with food-grade liners. They are suitable for above ground placement, and frequent cleaning and proper maintenance is advised.
Concrete- this is often more preferred because of its versatility. It is suitable for both above or below ground placement. You can decide to make one for yourself or have a company construct one for you. Apart from being quite attractive, another important reason why it is preferred is because, it reduces the corrosiveness of rainwater over time. However, they are prone to cracking and leaking, especially if clay soil is used.
Some other materials include, wood, stone and mason, polyethylene, fiberglass, in-ground polyethylene, ferrocement, plastered tire cistern, and even swimming pools. Knowing the options available to you is very important. This will help you better select the one that most suits your needs and pocket too.
