A fire hydrant is the primary method of firefighting in a municipal area. It is basically an outlet with a valve that provides water to the fire pumps engaged in firefighting. Laws for keeping operational fire hydrants at specific intervals and with free access in buildings, factories, urban and developed areas are an important component of fire control and safety.
A fire hydrant system is a water supply with a sufficient pressure and flow delivered through pipes throughout a building to strategically located network of valves for fire-fighting purposes.
In some circumstances, water from a reticulated fire hydrant system can also be shared with other safety measures such as automatic fire sprinkler systems or fire hose reels.
