Groundwater can disappear or be significantly reduced due to excessive pumping, a process called groundwater depletion. When water is withdrawn faster than it's replenished, the water table (the upper level of the groundwater) lowers, potentially causing wells to dry up. The disappearing of groundwater due to excessive pumping can be prevented through a combination of monitoring, regulation, and sustainable practices which are dependent on responsible consumption of operators and there is no system that could force them not to pump excessive water from the well, until now 

 This water well is also equipped with non-return valve at the base of the cylinder where ground water can enter the well but not out of it which only force user to use the water available at the cylinder rather than over pumping the ground water distributing the water table.
