Fire Hydrant
A fire hydrant is a visible fixture, basically an outlet with a valve that provides water to fire pumps engaged in firefighting. There are laws for keeping operational fire hydrants in buildings, factories, parking area, mine, roadside, industrial area and urban developed areas. It is an important component of fire and safety control that is connected to the municipal or a private water service network. They instantly provide the water required for fire extinguishing. In rural areas where the municipal water supply systems are not available, they use a dry hydrant that is unpressurized and permanently installed with one end below the water level of a lake or pond. The hydrants are painted red, yellow, orange, blue or green depending on the gallons of water they pump out.
