Question

why should we have covered drains ​

Answer 1

The sole purpose of a drain cover is to prevent environmental contamination. You have to realize that any chemicals which travel down the drain end up somewhere — usually in the closest body of water. Rainwater is typically carried through the drains to the nearest body of water, but unfortunately chemicals can also make their way down the drain. Taking the time to cover your drain is a simple way to prevent environmental contamination from chemicals used by your business.
