Rain Water Harvesting -Harvest rainwater to use in difficult times of drought.
Water a vital source for survival of livelihood. The average adult human body is 50-65% water. India is a house of a maximum number of the population comprising of about 63 million living in the rural areas without an access to fresh clean water. The ground level water is a scarce resource and with the increment of human population and damage to the environment, the resource is depleting continuously. Hence it is an alarming sign that we need to safeguard this resource in order to sustain the life of the future. Access to safe drinking water was declared as a human right by the United Nations but remains a challenge for urban India. As indicated by the World Water study, 31% of Indians had been in a circumstance where it was dangerous to drink water yet needed to devour it given no other decision and in this way experienced water-borne ailments, for example, loose bowels and gastroenteritis
Groundwater provides 80% of India’s drinking water and nearly two-thirds of irrigation needs. Over the last four decades, around 84% of the total addition to irrigation has come from groundwater. Moreover, 60% of India’s districts face groundwater over-exploitation and/or serious quality issues. In fact, 11% of the rural water supply is based on groundwater.
Now, as it is said that it has been an alarming sign that with the increase in population, more and more fresh water is the need for human life sustainability and irrigation we have to think for an alternative source of producing clean water.
And one of the best alternatives is Rain Water Harvesting.
What is Rain Harvesting?
The reaping of water just includes the gathering of water from surfaces on which rain falls and consequently putting away this water for later utilize. Typically water is gathered from the tops of structures and put away in water tanks.
Artificial revive to groundwater is a procedure by which the groundwater supply is augmented at a rate surpassing that under regular states of recharging. The gathered water is put away and drew in a different pipe circulation. This is an exceptionally helpful strategy for a creating nation like India in decreasing the expense and the interest of treated water and furthermore conserving the treatment plants task, upkeep, and dispersion costs.
Need Of Reserving Rainwater
- To defeat the insufficiency of surface water to meet our requests.
- To capture a decrease in groundwater levels
- To upgrade accessibility of groundwater at a particular place and time and use rainwater for manageable improvement.
- To build penetration of rainwater in the subsoil this has diminished definitely in urban zones because of clearing of open region.
- To enhance groundwater quality by weakening.
- To expand agribusiness generation.
- To enhance biology of the region by the increment in vegetation cover and so on.
- Putting away water underground is condition neighborly.
- It builds the profitability of aquifer.
- The aquifer fills in as a dispersion framework moreover.
- It lessens surge risks.
- Impacts ascend in groundwater levels.
- Mitigates impacts of the dry season.
Methods and Techniques:
The methods of groundwater recharge mainly are:
Urban Areas: Rooftop rainwater/storm runoff harvesting through
(i) Recharge Pit
(ii) Recharge Trench
(iv) Recharge Well
Rural Areas Rainwater harvesting through
(i) Gully Plug
(ii) Contour Bund
(iii) Gabion Structure
(iv) Percolation Tank
(v) Check Dam/Cement Plug/Nala Bund
(vi) Recharge Shaft
(vii) Dugwell Recharge
(viii) Ground Water Dams/Subsurface Dyke
The hills of India has been always fascinating to us with its natural beauty and in order to sustain it, we have to safeguard this ecosystem. Water being one of the key players and also at the same time being a scarce resource, it’s very important to preserve it.
Uttarakhand, situated in the western Himalayas, is a home for approx 10.32 Million as estimated in the year 2017 with an average increase of 0.04 Million in last 5 years. The natives here have to depend on fresh water from the small water tank and as per the rising population we have to practice alternate source for deriving fresh water and rainwater harvesting is the best option where people at minimum investment can get fresh water.
The rainwater can be stored in tanks and can be used for later. This technique is also very much useful in the case of irrigation during the period when rainfall is very low. Using this reserved water for harvesting will help in maintaining the proper line of production and help the farmers to maintain their income.
So, we must put into practice of utilizing the rainwater by reserving it for future use.
And we have only one thing to advise :
Do you harvest rainwater? If not, start today!
