See the pipes sticking out from the balconies at the top of our building? They are called spitters. They pour out water when it rains or if someone had a hose out on their balcony. I pointed them out to Tradie Brother one day and he was horrified at the idea. In his opinion, rain must go into gutters and downpipes and disappear from sight. They are great to watch when the rain is heavy. The force of the water can send a stream out quite a long way.
Now, who is thinking what about anyone standing below? Well, they don't really go into an area where there might be a lot of people and as the stream falls towards earth, it breaks up into large drops. It wouldn't be great to be standing below, but not as bad as you may think and if it was raining that much, then you wouldn't be standing outside.
