With water being the most important resource on our planet, rainwater harvesting is the smartest thing you can do.
Rainwater harvesting is the accumulation of water for reuse on-site, instead of allowing it to run off. In a world where water is becoming scarcer and demand is growing, rainwater harvesting is the solution.
Benjamin Franklin once said, ‘When the well’s dry, we know the worth of water.’ While a large part of the world’s population does not have access to running water, those who do can barely imagine a life without it. Have you ever experienced a water cut and found yourself turning on the tap without realising it? So many people have no idea just how much water they use in a day and are unlikely to have any idea how to cope in the event of a water shortage. Rainwater harvesting is an easy and affordable way of making the most of this valuable natural resource.
Rainwater harvesting is the accumulation of rainwater for reuse on-site that would otherwise simply run away. Rainwater can be collected from roofs and other surfaces and in most instances the water collected is redirected to tanks, reservoirs or underground holding cells. This water can be used for gardens, livestock, irrigation, domestic use (with proper treatment), etc. The harvested water can also be used as drinking water and for other purposes such as groundwater recharge.
Rainwater harvesting provides an independent water supply during regional water restrictions and in developed countries is often used to supplement the main water supply. It provides water when there is a drought, can help mitigate flooding of low-lying areas, and reduces demand on wells which may enable ground water levels to be sustained. It also helps in the availability of potable water, as rainwater is substantially free of salinity and other salts.
Quick and easy to install rainwater harvesting systems are not expensive. The system should be sized to meet the water demand throughout the dry season since it must be big enough to support daily water consumption. Specifically, the rainfall capturing area such as a building roof must be large enough to maintain adequate flow and the water storage tank large enough to contain the captured water. Rainwater harvesting is the answer, do it before the well runs dry!
