Ever wonder what all those holes and grates are by the side of the road?  Those are called storm drains. When it rains, the storm drains allow rain water that falls on the roads to drain into underground pipes. The underground pipes connect to rivers or lakes where the rain water can drain into an existing surface water body.  A lot of people think these pipes lead to sewer systems but now you know where they really go!

Do you have any storm drains on your street?  If so how many? And if not do you live in a rural town? Rural towns have ditches or long trenches on the sides of the road that collect the rain water.
