Water is the most important thing in our daily life.so saving the water is also the important thing.if water is not there then we cant servive.daily we are using the water for different uses.fue examples like washing,cleaning,drinking,bathing etc. so water is playing a key role on our life. not only now it will after few years also it play a major role. so we need to save the water.
In olden days also wastage is there.the wastage is also recycled without man interference. the wastage is also done by different ways like in the 6th and 7th standard books mentions that in the environmental science book showing the picture that is like ,the village having the pound ,in that pound the people are taking the bath oneside , house wife are taking the drinking water,otherpersons cleaning their cattle's etc.
so the olden days also there is the wastage mixed in the water time people are struggled and sustained with the situation.
later that govt constructed dams on the rivers.from there to they are giving the water to each village and each house(partially completed the work in some villages). Each politician says before elections if we wins in this elections we will provide the drinking water for the each house.after elections the politicians will not come to home.
how this problem solved in olden days:
in olden days the kings constructed the big lake(check dams) for storing the water.from there to people uses the water for their fields and house hold works.
now a days;
rivers are jointing it is good thing but river side people are dies for the water.then what is the use of the constucting dams.because dam will store the river water until it fill the level.the they will release the water .then the flow water speed is high it cant stop in the middle. it go until next dams.so what about middle villages how they will uses that water.
how to solve the problem now a days using riverwalls:
to overcome this problems ,is making the walls type constuction across rivers using the sand bags.like constructing the walls in the distance of the each 200m to 300m across the river and 3 to 4 feets height and breadth is 5to6 sandbags side by side.
after constructing this walls we can store the water upto 3 to 4feets height water and it covers entire border of the river.if it overflow the water then it stops at next wall(sandbag walls) .so nearly 200m to 300m meter water will saves and next wall also saves 200m to 300m like wise saves upto next dam.
if govt of the india take care and construct this type of walls on every river so we can store the water.
for construcing this walls cost is also less comparing constrcting big dams.sand will available in the river and bags cost is also less and only the labour work is only required.for the use the army and village people help so we can constructing riverwalls.
for inspecting this we need the employee so we can generate the job.for very 5 to 10km distance
