|Description||The layman term for drain cover (grate) is manhole cover. Say "manhole cover" and pictures of spies/heros using the underground sewage system popping out of manhole cover in Hollywood films appear.|
Historically ever since Man invented the sewage system since the Roman Times to drain water and urban waste away for sanitation purposes, manhole covers (drain covers or grates as we would like to call them) have been invented out of the basic need to prevent people from falling into underground sewage as well as to prevent large objects from entering the drains which cause choking which eventually may cause flooding.
Fast forward to the modern day, the sewage system is still being employed under all cities all over the world. Instead of the crude stone manhole covers the Romans use in the ancient days, now floor grate cover have special steel reinforced stone gratings that serve the thousand year old function of covering the inlets of our sewage system.
