How to build the water sources in villages

The mojor water source for water is rain in many places. Water storage system consists of small lakes to big reservoirs. There will be small lakes (single or multiple)for each village, which are filled by rain water. A Dam kind of stucture is made to store and release the water regularly. This lake will have a construction in one of the corner, when water is increased a certain level water will overflow from this place. There will be many small lakes which were filled up in the rainy season and overflown. These water is diverted to a very big lake. This big lake can store much more water than the smaller one. There were many small streams going through. These streams are only visible in the rainy season. After the rains are stopped these streams are dried up. So, These small streams  can not cater water to the crops as expected. If there is big lake on it's way. Then, water was stored in there. 

90% of the small streams must have died by now. Because, of sand being filtered and used as building material. Most of the Water wells were dried as the use of pump motor instead of well water for farming. Water levels need to be increased to have water in the wells. Water needs to preserved in the lakes. Water needs to preserved for drinking. For this we need greenery. 

What to do? Take a village as a example Unit. Survey the village. How many lakes are available. How many Streams are passing through the village (through the dry lands and wet lands) 

Lakes: Lakes has to be renovated. Natural streams which bring water into the lake should be noticed. These source streams must renovated. 

Streams: Greenery brings the rains. We can build the greenery along the streams. Which are filled up with water during the rainy season. Lot of plantation has to be done and maintained here. It helps cooling the weather and bringing the rains. 

How?

There were lot of youth clubs were in existence earlier. Village youth was involving some activities for the village. Now the functioning of the youth clubs is only for the sports. But, if proper funds are given and educated and motivated properly, These youth clubs can do more. They really take things into the people and can be used a source for the movement in villages. Govt support can be taken for funding to get the trees from Nurseries.
