Fire Hydrant Systems
A fire hydrant is an above-ground connection that provides access to a water supply for the purpose of fighting fires.
The water supply may be pressurized, as in the case of hydrants connected to water mains buried in the street, or unpressurized, as in the case of hydrants connected to nearby ponds or cisterns. Every hydrant has one or more outlets to which a fire house may be connected. If the water supply is pressurized, the hydrant will also have one or more valves to regulate the water flow.
