Rainwater storage tanks are becoming a more common sight in different parts of the world today for a myriad of reasons. The most well-known reason is the global water shortage problem, which is made worse by climate change. But even without the problems of water shortage and climate change, which is aggravating it, a rainwater storage tank is still a worthwhile investment for your home for the following reasons:
* You contribute to the lessening rate of soil erosion in your area. The capture and storage of rainwater prevents some rain from washing out some topsoil in your area. This can help keep the soil in your area suitable for gardening purposes.
* You help the water table or ground water replenish. While it’s true that in rainwater harvesting, collected rainwater goes straight to the rainwater storage tank, it is also true that much of the rain that falls in your area goes to the ground, if not down the sewage system. Any rain that falls down the ground can help in replenishing the ground water or water table deep in the earth’s surface.
The ground water or water table is one of the sources of mains water, and if so many people rely on mains water for different chores, it won’t be long before a water provider will need to turn to another source to be able to continue providing water. Thus, by having a rainwater harvesting system set up in your home, you are not only ensuring a steady supply of water for yourself, you are also ensuring a steady supply of water for others.
* You help water providers reduce their use of energy that’s sourced from less-than-ideal sources. Rainwater does not need to go through so many machine-based and chemical-based processes in order to become clean. The water that’s used in mains water, on the other hand, before it becomes suitable for use in numerous tasks and chores, needs to go through numerous machine-based and chemical-based processes. The power sources of many of these processes is fossil fuel, which isn’t exactly environment friendly.
Also worth mentioning is the fact that the energy used to pump water to millions of homes in different parts of the world is also from fossil fuels.
Therefore, reliance on rainwater for at least three tasks or chores which require the use of water can help decrease the need for mains water providers to use fossil fuels for the above purposes.
It’s also worth mentioning that in order for a rainwater storage tank to be truly considered a worthwhile investment, it’s important to have the rest of the rainwater harvesting system properly set up in your property as well. A typical rainwater harvesting system is composed of a catchment area or roof (preferably an unpainted metal one), a gutter, a downpipe that leads to the rainwater tank itself, the required number of meshes, screens, filters, and disinfectants, pump, and a number of pipes to connect the rainwater harvesting and plumbing systems.
