A school beside a lake.
The lake is healthy and full of water.
The school has dug multiple deep borewells over the past several years - all of them deeper than 800ft - found little or no water.
School is unable to keep toilets clean for lack of water.
Decides to dig a shallow well of about 20ft depth
A donor steps in to fund the shallow well. The well is dug
The open well fills up rapidly - with water available at 8ft below ground level even in December.
A pipeline is laid to pump the water from the Open Well to the Overhead tank from where it will flow into the toilets
Yes - the water has to be tested, the rate of flow measured :) -but it is apparent that the water is of sufficient quantity
A good example of people and groundwater knowledge coming together to create a simple working solution
