why do we need rain water harvesting

One of the easiest ways to save water is to simply collect it, and thatвs a practice that is referred to as rainwater harvesting. Rainwater harvesting is essentially the collection of rainwater in large tanks (like a cistern) thatвs then transferred to containers until itвs needed for use. In most cases, the water is used directly from these containers without being purified or filtered. This practise first became popular as a method to collect and store water in areas where water shortages are common. But, given its many benefits, it has now become extremely common with anyone whoвs looking for a free, easy and more environmentally friendly way of using water in their home or commercial premises. Rainwater harvesting is so important for lots of different reasons, with the following being just a few of them;
Youвll have water when you need it Non-potable water has many uses; you can use it to flush the toilet, water your flowers and wash your car etc. Harvesting rainwater will ensure that you always have water for these tasks, even in times when the normal water supply is cut off.


Rainwater is better for the garden Nature has relied on rainwater for its growth for millions of years and that still remains the case, even today. Water your plants and flowers with rainwater thatвs relatively pure and free from toxins and it will flourish. It is superb for irrigation The collected water reduces flooding and decreases soil erosion by decreasing the likelihood of run offs during periods of heavy rainfall. This is good news for our rivers, streams, oceans and lakes, as they will be less polluted over time. Itвs super easy to install Getting your set up is super easy and very cost effective. All youвll need is a system that will collect the water, some and a tap or pipe system that will give you quick access to the water once itвs collected. A very easy way to collect rainwater is to direct the rain that collects in your roofвs gutters into a storage tank where it can be then transferred into smaller containers В в itвs that easy! It is a more sustainable practice Using harvested rainwater is a brilliant way of lessening your carbon footprint and living in a more environmentally friendly way.


Wasting perfectly clean potable water to do things like water plants and flush toilets isnвt a sustainable practice, and it should be avoided if possible. It is much more sustainable to use water from the tap for cooking and drinking, and use your harvested rainwater for everything else. Rainwater harvesters are winning There are endless reasons why collecting rainwater is essential, from doing your part for the environment and saving money on bills to having access to water all of the time. Getting started takes no time at all and doesnвt cost much so why not start off 2018 on a really positive note? Your garden, your pocket and our environment will thank you for it! Why Rainwater Harvesting? "Are we condemned to be largely spectators? Can we affect the course of events? Can we claim 'compassion fatigue' when we show no sign of consumption fatigue? " Water availability per capita has been on the decline in India.


Two reasons have been the increasing demand for water and the increasing population. The quantum of water available to the country being fixed the increasing demand reduces per capita water availability. Agriculture continues to be the single largest consumer of water however industrial demand for water shows the fastest growth. Especially South India and in particular Karnataka is a drought prone region. The state enjoys the dubious distinction of having the second largest area prone to drought next only to Rajasthan. Bangalore gets most of its drinking water from a distance of 95 kms. and a depth of 500 mts. It makes ecological and financial sense not to waste a pure natural resource available in large quantity on one s roof. In the case of a homebuilder, at an initial stage of construction, investments in time, design and money are minimal for adopting roof rainwater harvesting. Ground water sources are increasingly getting depleted or are getting polluted. Borewells are either silting up, getting short of water or are drawing polluted water.


Private purchase of water from tankers is unreliable in quality and is also expensive. It encourages water conservation and self-dependence. it is being recognized that people from various sectors have to become partners in the solution process and not remain simply as institutional beneficiaries. India is blessed with adequate rainfall as a whole, yet there are large swathes of dry, drought prone area. In many other places the quality of groundwater is not good. In such places rainwater harvesting can provide lifeline water for survival and more. One acre of land in Bangalore for example, with about 900 mm of rain receives nearly 36 lakh litres of water as endowment. A small 100 square metre of roof area would receive 90,000 litres of rainwater in an average year of rain. You can calculate what is the potential of rainwater harvesting in your area and have one appropriate for you. Rainwater harvesting has tremendous potential and it is up to each one of us to push this technique further for a sustainable water situation for India.
