Does anybody know what these are called?

Okay, if this sounds random or doesn't make sense, I'm sorry, ,but I need to know what these are called. Along some highways, you get these hills that are really steep, and are usually one or two storeys high. In most cases they are tiled, and midway up, have the ends of large pipes coming out for a couple of feet. I think they are storm drains, but I'm not sure. If anyone has any idea what I'm going on about, can you please help? THanks so much in advance.
