How Do Rain Water Tanks Work?

Most homes have mains water that is supplied by the local authorities. However, in some areas there is either no mains water or there is not enough to meet desired usage levels, meaning that water must be obtained through some other method. In some cases, this will be through spring, but if there is no reliable underground water supply, the cheapest and easiest way to get water is by having a rainwater tank.

A rainwater tank is an extremely simple system of water supply. Usually, it is fed from a catchment area, most commonly the roof where rainwater is funnelled through gutters and pipes into a tank. Having a rainwater tank requires a high standard of guttering made from specific materials, as well as having a number of filters and screens to stop the unwanted matter from entering the water system.

The major drawback with the rainwater tank system is that in times of drought you will run out of water, meaning that they are only practical in areas that have relatively consistent and constant rainfall. Rainwater tanks have become increasingly common in areas where water restrictions are in place as they are a great way of supplementing water reservoirs.
