What is a fire hydrant used for?

A fire hydrant is specifically designed to provide quick access to a public water supply for firefighting operations. Firefighters can connect their hoses to hydrants, allowing them to draw water quickly and efficiently in emergency situations. This rapid access is crucial during a fire, enabling teams to combat flames effectively and protect lives and property.

While hydrants might be present in parks or residential areas, their primary and most critical function is related to emergency response. Decorative uses or residential water supply roles are not their intended purposes, and they are not utilized for drainage, which is a different infrastructure concern. Hence, the reason for the choice of the first option is that it directly addresses the essential role fire hydrants play in supporting firefighting efforts.
