In coastal areas over extraction of ground water leads to saline water intrusion. Rooftop harvesting is effective and very economic. Rainwater Harvesting at Homes The journey of a thousand miles starts with one step. Why is Rainwater Harvesting Important? But with the depleting levels of water, we have become increasingly aware of the and need to save it. Speech on Rainwater Harvesting 2 Respected Parents of all the Children and My Dear Friends — Warm Good Evening to one and all! Collected rainwater can be stored for direct use or can be recharged into ground water. Rainwater harvesting is the way to reduce the use of ground water as well as maintain its level forever in the future.
This makes them fall ill and at times also gives way to epidemics. Ease of operation and maintenance is designed into every system. The problem of water shortage in arid and semi-arid regions b. We should bring our old traditional harvesting practices using new and effective technologies to make easy water supply in all the regions. When fed into the ground level wells and tube well are prevented from drying up. Even animals suffer from scarcity of water.
So the seriousness of the issue has been realized the seriousness and efforts to overcome this problem has been initiated. Today, many people dump their garbage into streams, lakes, rivers, seas, thus making water bodies the final resting place of cans, bottles, plastics, and myriad of chemicals. All it requires is a waterproofed structure within the ground or over the ground that can hold the water during rains and prevent its loss as seepage. Water collected from roof tops, courtyards and similar compacted or treated surfaces is used for domestic purpose or garden crops, or for groundwater recharge. Information can be acquired from a variety of television networks, newspapers, magazines, websites, programmes and publications.
I, Rajesh Sharma — the chairman in Water Conservation Department of Jaipur, am your host for today. Asphalt shingles are adequate but produce less water in summer and are harder to keep clean. The most common storage tanks are the above ground molded polyethylene tanks ranging in size from 300 to 3,000 gallons. Treatment of rainwater is often simpler than treating water from wells or surface streams. This stored water can be used later for various purposes like domestic or small commercial use, for farming, for too.
The importance of rainwater harvesting lies in the fact that it can be stored for future use. This is a global problem and needs a speedy solution. In forests water seeps gently into the ground as vegetation breaks the fall and flow of water. This helps in two things, solving the water crisis and preserving environment. For centuries, governments have manipulated the truth to suit their wants and needs.
Rainwater is one of the purest sources of water available. This will also help to conserve the valuable fresh rainwater. The technology remains more or less the same and may be somewhat more hi-tech. Now, the question that arises is what are the advantages of rainwater harvesting? The risk of water scarcity in the future has been increased to a great extent and can be life threatening if some effective solutions are not followed. The main purpose of the rain water harvesting is to utilize the locally available rain water to meet water requirements throughout the year without the need of huge capital expenditure. Although the earth is three-fourths water; very little of it is suitable for human consumption or agriculture.
Now, the question that arises is how to bring the situation under control? Rainwater collected from rooftops is free of mineral pollutants like fluoride and calcium salts which may be found in groundwater. Would you rather live in a polluted dump? Nature has its own systems of recharging groundwater. Importance of Rainwater Harvesting 1. Micro-catchments water harvesting is a method of collecting surface runoff from a small catchments area and storing it in the root zone of an adjacent infiltration basin. Without free press, the oppression of rights by the Taliban and other such regimes would go past unheard by an otherwise deaf society. Rain Water is free of cost provided we invest a little for building the Rain Water Harvesting System. Health benefits of rainwater d.
It is very effective in the hilly regions and desert regions of the India and other countries. If rain water, which comes for free, can be collected and stored, instead of letting it run off, it could be an alternative to back up the main water supply especially during dry spells. Although there is a huge improvisation in the overall scenario of drought situations, still there are thousands of villages which are still struggling for the water for drinking and farming. Rough collection surfaces are less efficient at the conveying water, as water captured in pore spaces tends to be lost to evaporation. The rainwater harvesting can be done by various means and technologies, such storing the rooftop rainwater into the tanks, storing the surface water by building temporary dams, storing the water into the fields and even by the collecting fog. However, ground water recharging technique is a new concept of harvesting.
