☆Answer☆
The construction of buildings and roads are gradually covering the open part of the soil with concrete. As a result the rain water run offs fail to percolate (movement of water) through the soil.
Water table is the upper level of an underground surface beneath which rocks and soil are completely emerged under water. The runoff water percolates through the soil and reaches the layer of ground water. As a result the water level of the water table rises up.

Explanation:
Cement roads would deplete city’s groundwater reserves in a big way as they would prevent percolation of rainwater. The civic body has not created pits for plantation while the existing trees face the risk of choking. Also, accidents would increase due to skidding of vehicles on cement roads. These are the findings of a study done by students of Matru Sewa Sangh (MSS) Institute of Social Work, Bajaj Nagar, about the impact of cement roads on Nagpur’s green cover and water table. The students found lack of measures to mitigate environmental hazard, about which they have written to the mayor and municipal commissioner.
The students had undertaken a field action project as part of their compulsory ‘Environmental Studies’ course offered by the Nagpur University (NU). Principal John Menacherry said the study titled ‘Community action for environment’ was carried out using ‘observation’ as the methodology by 60 second-year BSW students but others from the college also chipped in.
