**3. Problems associated with groundwater overexploitation**

#### **3.1 Lowering of the ground water level**

The most critical effect of over-pumping of groundwater is that the water table may be lowered. For water to be withdrawn from the aquifers, water should be pumped from a well that reaches beneath the water table. If groundwater levels reduce too far, then the well owner may have to deepen the well, drill a new well, or, at least, lower the pump below the water table available. Also, as water levels fall down, the rate of water the well can yield might also reduce.

#### **3.2 Increased costs for the user**

As the depth of groundwater increases, the water must be lifted from the depth of groundwater to the ground surface. If water pumps are used to lift the water, more electrical energy is required to operate the water pump. Under this situation, using the well can become costly to users.

#### **3.3 Reduction of water availability in water bodies**

There may be more of an interaction between the water in water bodies such as ponds, lakes, rivers and streams, and groundwater than the most of the people *Groundwater Recharges Technology for Water Resource Management: A Case Study DOI: http://dx.doi.org/10.5772/intechopen.93946*

think. A proportion of water flowing in rivers contributed from seepage from the streambed to groundwater. Groundwater contribution mainly depends upon on the parameters of physiographic, region's topography, soil, geology and climate.
