What is water retention?

Rainwater harvesting is the collecting and storage of rain water for a productive purpose. Collect the natural water that is falling from the roof of your house / house and collect and store it.

Why is water retention?
Today, we can not stop the rain water from being a waste of good water shortage.

Benefits of extraction of rain water
Apart from underground water or municipal water supply, other facilities are also available
It can be used for construction or farming in any other irrigation area.
Chemical free, pure, exemplary water
Very low cost water supply
The reduction of flooding will reduce the part of the floor.
Areas that are suitable for rainwater harvesting
Where the underground water is scarce
The groundwater is the underground water
Elevated areas / mountainous areas
Occurrences, such as earthquakes and floods, are usually areas that occur
In areas with saline water reservoirs
In areas where population density is low
In areas where water and electricity are high
Where the hard water (or) contains high saline water
Rain water can be used
Toast, cooking, bathing (drinkable)
To clean the toilets
Wash clothes
Pet needs
How to make rain water harvesting
There are three things in the process of extraction of any rain water. Catching, supplying, storing. There are two sections in the process of getting water

The use of water from the house to the house for the purpose of home work
The process of providing water for the farming area, the farming area (or) to the area in which it is adjacent.
There are six fundamental concepts on how to capture rain water
Pairing: collecting water from the patio
Supply: Storage from vessels (or) tubes, patio (or) catching area.
Cleaning the roof / cup: removing the contaminated material by filtration through the flow of water through a waterproof velocity.
Storage: Building structures / large tubs to store protective water on the patio. That is not the insect.
Cleansing: Washing water collected by filtering, ozone and ultraviolet light to refine and drink.
Delivery: The tiny machine and pressure tanks will help deliver rain water.


Rainwater harvesting in rural areas:

Construction of massive wells in some villages in the villages. The hand-powered tube well is constructed at ten and twenty feet for this mass well. Keep the tube well and clean the area around the mass well. Washing (human-related tasks, wash the cattle, wash the bicycles) and make aware of the lack of exertion.
Clean the tube in the existing water pipes in the villages and clean it every three years. The construction of the dam (checkdems) will prevent the flow of water from the streams that have smaller rivers and canals in the absence of water.
Extracting the roof water
Water sampling from the patio / ceiling in rural schools
In the desert areas of India, there is a system of extraction of water with minimal costly expertise in the preceding hundred years. More than two decades of bare foot college offers good water in remote rural schools in fifteen states for 320 people. Water harvesting from the cups of schools is stored in underground tanks. The main problem is the lack of good water in remote villages. There are two advantages to the construction of the rain forests.

Especially in the summer (4-5 months), there is enough water to drink.
Water supply throughout the year improves sanitation. E.g. use of toilets to toilets that cost less water.
Rain water harvesting scheme for school


The school is a water sample tank

Construction of rain water harvesting
Before the construction of the Vanni Tip Complex system, water supply in the village requires a shortage of water, about existing water sources, the roof area and the needs of the village in the village.

Why build large tanks in the underground soil for rainwater?
Large water tanks should be constructed with lime (or) local ingredients to stay clean until raining again.
The cold storage of cold water in the winter and winter is a stock of natural resources.
Like tanks on the ground, large underground tanks can be used for longer periods without maintenance.

The place where the bigger is

Students must have a tank near the main building of the school to get access to water.
Depending on the distance from the tank to the building, the Tundi Earth's surface is strong and the area formed by stone layers is 3 to 5 feet, and a soft area up to 10 feet.
To use a minimum length of tubular tubing with water to the tube from the roof to the tank (at least 4 inches).
If the upper layer of the underground is tight, do not try to dig deep into the deep. There should be more than one-third of the Earth's surface and more than 1/3 of the tank.
Equipment for construction

Local building materials (bricks, rocks)
Lime / cement
Waterproof powder (gypsum)
Coarse sand
Equipment used for the roof of the area (ferro cement / sandstone)
Tank shape


There is a tank shape depending on the type of soil. Typically, the traditional method is rectangular, cylindrical. The rectangular tank is good for hard rock. Simple technology. Dug powder and close the top part with locally available stones. Can be used to conduct classes or use as a school venue during the winter season.
A specially stacked tank is suitable for the desert area. Knowledge of the village people in Thar Desert has created water tank structures with an uninterrupted technology system. This is an incredible truth. The masks and sculptors in the local village are constructed with locally available kiosks of 100 m in the cylinder tanks. Construction of cylindrical tanks is challenging to the designers (civil engineers) who build structural structures.
