Question

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

​

Answer 1

The roads and the footpaths should be built in a sloping manner to make the rainwater move to the sides and fall through the drainage opening under the road.  

Explanation:  

• The city planners must take into consideration the fact that in areas that suffer from heavy rainfall each year and that lead to flooding, the construction of the roads and the footpaths must be done in a manner that would help the rainwater pass on to the underground drainage instead of getting accumulated over the road.
• If the roads are built with a slope towards the rise, the rainwater will fall through the drains and this would stop the chance of flooding.
