Drains that are not covered may get blocked with solid wastes like plastic bags, rags and gravel. Such drains are flooded with dirty water that stagnates and is polluted emitting foul smells and providing breeding grounds to various microbes.

Sewage wastes also carry germs that cause serious waterborne diseases like cholera, typhoid, dysentery, and jaundice.
