In towns and cities, generally, the bore wells have to be dug very deep to get water as compared to bore wells dug in villages. Give suitable reasons.

In towns and cities the bore wells have to be dug very deep to get water because in town and cities water is used excessively, which depletes the ground water. Secondly, in towns and cities roads are made of asphalt and vast areas of soil are concreted. As a result, rain water cannot percolate. Therefore, depleted ground water is not replaced. As a result ground water level further decrease. But in villages vast areas are open and soil surface and have fewer asphalted roads and concrete surfaces. Thus, larger soil surface area is available for rain water to percolate into the soil easily and recharge the ground water. As a result, even shallow bore wells yield water.
