Rain Water Storage

Water is a very important and useful resource. With global warming and climate change, it has become imperative to find ways and means of ensuring water security for ourselves and future generations. One way of doing this is rain water harvesting and rain water storage.

Before practicing rain water storage, you first have to harvest the rain water. Rain water used to be harvested many years ago before cities and towns developed and the system of rain water collection was replaced by a centralized water supply system. Back then, the rain water was harvested for drinking, cooking, other household uses as well as for farming. Today, rain water harvesting is done so that water can be used for landscaping and other uses such as flushing toilets. This is so as to reduce the need to use clean drinking water for these purposes.

Rain water is preferred for landscaping purposes because it is usually rich in nutrients and therefore reduces the need for using fertilizers. Also, no chemicals such as chlorine have been added to it. Other added benefits of storing rain water is the reduction of water bills and removing the need to stick to a watering schedule (some municipalities have one).

There are two main methods of rain water harvesting. They are harvesting rain water from roof tops and surface run off harvesting. In surface run off harvesting, the water is directed so that it recharges an underground acquifer. Roof top rain harvesting, which is the most common harvesting method, has several components. These components include the catchment area (the roof), the rain water transportation system (the roof gutters and down spouts) and the rain water storage tank or facility.

The rain water that is harvested and stored is not typically used for drinking. This is because the rain water can be contaminated by pollutants. However, it can be used for this purpose. A filtering system (ultra violet filtration, reverse osmosis) can be added to the rain harvesting system so that the water that gets to the storage facility is potable. There are also some precautions that can be taken to reduce the risk of rain water contamination.

The roof or catchment area should be kept clean. Painting the roof should be avoided as majority of paints contain toxic substances that will contaminate the water. When the rainy season is anticipated, the rain water storage tank should be cleaned thoroughly.

Rain water storage is quite commonly practiced in India, Africa and other less developed nations. However, this practice is catching on in the developed world and specifically in the United States.

Rain water storage also has the added benefit of being a water conservation method. If the rain water is not stored, it will simply go to waste.

Though our website is mainly geared towards emergency water purification methods, we do like to add related information such as this article on rain water storage. One reason we are doing this is that if you harvest and store rainwater you will always have a good supply even in a disaster situation.
