Collected water in cooler, potholes, drains etc are harmful for us. Why?
Answers
During the rains part of the rain water flows on surface and part of it percolates through the soil mass as gravitational water until it reaches to the ground water. Some water is retained in the pores of the soil mass and on the surface of soil particles which cannot be drained by normal gravitational methods and this water is termed as held water. It is required that the surface water from the carriageway and shoulder should effectively be drained off without allowing it to percolate to subgrade. The surface water from adjoining land should be prevented from entering the roadway. The side drains should have sufficient capacity and longitudinal slopes to carry away all the surface water collected. Also in waterlogged areas special precautions should be taken. There are many such roads which are not having the proper drainage system. This causes the failure of the roads due to many reasons like increase in moisture content, decrease in strength, mud pumping, formation of waves and corrugations, Stripping of bitumen, cutting of edges of pavement, frost action etc.
Types of Drainage System
This work shall consist of constructing surface or sub-surface drains in accordance with the requirements of
these Specifications and to the lines, grades, dimensions and other particulars shown on the drawings or as
directed by the Engineer.

The reason is if we collect water in coolers, flowers pots it will give birth to the dangerous mosquito which spreads virus and causes dengue and Malaria to us humans.
