Cities have special helpers called drains that carry away all the rainwater. It's like having a giant sponge underneath the city that soaks up water and sends it somewhere else, like a river or a lake. When it rains hard, these drains work really fast to keep the streets from turning into puddles.
Examples
- A street drain acts like a small river that carries away puddles from the road.
- During heavy rains, water flows from rooftops into gutters and downspouts to keep basements dry.
- Pumps in some cities can move thousands of gallons of water every minute.
