Harvesting rainwater - the best water saving practise.
The water you drink today has likely been around in one form or another since dinosaurs roamed the Earth, hundreds of millions of years ago. While the amount of freshwater on the planet has remained fairly constant over time – continually recycled through the atmosphere and back into our cups – the population has exploded. This means that every year competition for a clean, copious supply of water for drinking, cooking, bathing and sustaining life intensifies.
Water scarcity is an abstract concept to many and a stark reality for others. It is the result of myriad environmental, political, economic, and social forces. As much as we waste it, we must conserve it. There are a lot of ways through which we can save this important resource, rainwater harvesting being one of them. It is one of the world's oldest water supply methods which is currently enjoying a revival in popularity. Rainwater harvesting means capturing rain where it falls or capturing the run off in your own village or town. Normally, water is collected from the roofs of buildings and stored in rainwater tanks. This is very common in rural India. Water can also be collected in dams from rain falling on the ground and producing runoff. Either way, the water collected can be considered to be precious.
Rainwater harvesting is a technology used for collecting and storing rainwater from rooftops, the land surface or rock catchments using simple techniques such as underground check dams. The harvesting of rainwater simply involves the collection of water from surfaces on which rain falls, and subsequently storing this water for later use. And taking measures to keep that water clean by not allowing polluting activities to take place in the catchment.
Another way of collecting rainwater is to build up a water tank and have a gutter and pipe from your roof run straight to the tank. While this is more efficient than some other prevalent methods, the water you collect may not be suitable for drinking since the water may have pollutants from your roof.
Perhaps the best way to collect rain water is to have an efficient rain water collecting system that not only collects water but also treats it so it can be consumed. Investing in a great rain water harvesting system is well worth it.
There are a number of benefits of rainwater harvesting. If you have an efficient rain water harvesting system in place, you can rest assured you always have a water reserve in case of water shortage. Furthermore, rain water that has been treated by a rain water harvesting system can be consumed for drinking. You can also use the rain water you collected for cleaning your car, washing your clothes, watering your plants, and for other similar purposes.
Tamil Nadu is the first Indian state to make rainwater harvesting mandatory. In May 2014, the state government announced that it will set up 50,000 rainwater harvesting structures at various parts of the capital city of Chennai.
Availability of sufficient water in an area does not mean that water supply will be there forever. If the favourable conditions disappear because of natural causes or human activities, there can be a shortage. We are coming forward and taking the pledge to conserve water in every form possible, are you? A small step to begin with can go a long way. Like Eckhart Tolle said, “The primary purpose of life is being in the ‘NOW”.
