Rainwater harvesting

Rainwater harvesting is the process of collecting rain water and making good use. There are different ways to accomplish this task.

Rainwater harvesting refers to trapping and storage of rain water so that it can be used later if needed. As the rain falls, water is directed to a suitable collection point.

It can also mean that before water is collected water and become underground water.

This is a practice that has been for a long time. The only difference is that better methods have now been developed to make this process a better success. New technologies have come into play and now making the process easier and more efficient.

Requirement

Today the lack of quality water has become a cause for concern. Although pure and good quality rain water flows very soon.

But if it is collected then the control over the water conservation can be found. Given the current water conservation, this is the only option left by which we can get solution of the water crisis.

Methods of Rainwater Harvesting

There are several ways in which rainwater can be harvested. Some of these methods are very effective and can help in collecting lots of water for commercial activities, while others are suitable for cutting water only for home use.

Each system has its qualifications and defects, these are the common methods of rain water harvesting:

1. Surface water collection system:

surface water is only water which accumulates on the ground surface. When rain water falls on the surface of the earth, it usually flows in the slopes because it leads to a point of depression where running water can be gathered. Surface Water Storage System Before it flows in other places, before this, collection of ground surface rain is enabled.

Examples of such systems include rivers, ponds and wells Drainage pipes can be used to direct water in these systems. Water can be obtained from these sources and can then be used for other purposes.

2. Roof system:

They can also be used for rainwater harvesting. They can be used to direct rain water on the roof of a building in containers or tanks, these tanks are usually elevated, when the tap is opened, the water flows in high pressure.

This method of rain water harvesting is good because the stored water is mostly clean and generally it does not require any other treatment to fit it for human use.

3. Dam:

These are obstacles that are ready to be trapped in water. Rain water can be stored directly in them or drainage systems can be made to direct them in water. Collected water in dams is used for irrigation purposes or is distributed for home use. They can be used in ways they are modeled. Unlike ponds, measures are taken to reduce the amount of drainage in the ground.

4. Underground tank:

These are ideal for collecting water from rain. They are digging in the ground and building a space that is ready to reduce water intrusion. The top is also closed and the water is obtained through the piped pipes in the tank.

To get water out, the pumps are used. Underground tank is very good for rainwater harvesting because the rate of evaporation decreases because they are underground where the sunlight does not really penetrate.

5. Barish usar:

Sometimes a rainbow may decide to collect the rain from the sky directly. They look like umbrellas or inverted funnels, some are usually attached to a pipe so that the collected water is guided somewhere else. Some people make a little improvement by placing the container of the underground collection on the ground with only raindrops. This is an easy way yet effective.

6. Water collection reservoirs:

The collected water through this method is not really clean and can be contaminated. However, it can still be used for crop irrigation. Such rainwater is cut from the roads and the pavement.

7. Barrage:

A barrage is a dam in which there are many openings which can be closed or opened to control the amount of water passing through it. It is usually large and can be used to collect lots of water.

8. Slope:

When rain is collected under the slopes, it gets rain water. When it rains heavily, the level of water can move towards the hill, this is a simple and natural way to harvest rainwater.

9. Trench:

This is another great way of rainwater harvesting for irrigation. When rain occurs, water is directed to the farm using trenches. This is one of the traditional methods of rain water harvesting which is still in great use.

10. Rain barrels:

They are also used for rainwater harvesting. They are specially designed for this purpose and can be purchased from retail outlets. Varsha Barrels are used to store rain water falling on roofs.

Benefits of Rainwater Harvesting

1. Water for domestic use:

Rainwater harvesting is beneficial because it provides a source of water for domestic use. The collected water can be used for home cleaning purposes, laundry and cooking. When treated, it is good to drink rain water. This is an easy way to get water for use at home.

2. Water for industrial use:

Industries can use rainwater for their use in some processes. Rain water for industrial use is generally cut on a large scale. Such companies can build their own dams for rainwater harvesting or make underground tanks.

3. Complementary Water Source:

Due to the lack of rainfall in many areas, water has suffered due to lack of water and as a result of high rates of evaporation.

It can be difficult to obtain reliable source of water during these periods due to high demand and low supply, people who sell water can increase their prices. Rainwater harvesting is therefore seen as a method of preparation for sunny days when the water is rare.

4. Cost Effective:

We basically throw rain water for free because it is happening naturally. If you shop for adequate water during the rainy season, you do not have to pay for water services because you will have enough supplies to stay in the summer. It will reduce your monthly expenditure on water bills.

5. Reliable flow of crop water:

Regardless of the rainfall of the rain water depends on rainfall, once the stored, the available quantity supply is guaranteed. There may be an uninterrupted flow of water from the storage place until the amount of harvesting is done. This can not be said when you depend on external sources for your water supply. Location-suitability also benefits as the source of water is in place of your stay.

6. Influence of flood Mitigates/Reduces:

Storage of rain water plays an important role in reducing or reducing the effects of flood. When rainwater is collected through the trenches in the fields or in the dams, its movement is controlled.

This prevents the accumulation of water in an area, which often causes floods, rivers can also overflow and can cause flood in adjacent areas. The negative effects of floods are very high and expensive, hence, the accumulation of rain water is an effective way of reducing the effects of this natural disaster.

7. Building and Construction:

Collected Rain Water can be used for construction and construction. The process of building a house requires a lot of water. Rainwater harvesting will take advantage of water for this activity.

8. Helps in preventing water pollution:

Rain water flowing on the surface of the ground can take many impurities and toxins along with it. When it flows into water bodies, then due to these impurities, it pollutes the storage of rain water, hence the pollution of water bodies.

9. Irrigation:

Rainwater is good for cultivation because once it is harvested, it can be used especially for irrigation during the summer. Therefore, there can be a thriving farm and can detect a bumper crop.

10. Saves potable water:

Instead of using clean and treated water for other purposes in the wash and toilets, rain water can be used. It saves potable water, which will then be used only for drinking and cooking.
