How should roads and footpaths be built to make rainwater seep into the ground?

उत्तर
If the entire road and footpaths are made of concrete. there would be a problem for rainwater to seep into the soil. Therefore, some adjoining parts of the road and footpath should be kept without concretization so that rainwater could seep inside. Similarly, if a little gap is maintained between the two adjacent tiles on the footpath, rainwater can percolate inside.
