The video re-shares the image of a guy taking water from a public fire hydrant, he uses it for his own work, while there is a fire hydrant that can only be used in
emergency in case of fire. This act of the guy will probably be punished if discovered by the police, which is really not what can be used there.
A fire hydrant, waterplug, or firecock (archaic) is a connection point by which firefighters can tap into a water supply. It is a component of active fire protection. Underground fire hydrants have been used in Europe and Asia since at least the 18th century. Above-ground pillar-type hydrants are a 19th-century invention.
Before piped mains supplies, water for firefighting had to be kept in buckets and cauldrons ready for use by ‘bucket-brigades’ or brought with a horse-drawn fire-pump. From the 16th century, as wooden mains water systems were installed, firefighters would dig down to the pipes and drill a hole for water to fill a “wet well” for the buckets or pumps. This had to be filled and plugged afterwards, hence the common US term for a hydrant, ‘fireplug’.
A marker would be left to indicate where a ‘plug’ had already been drilled to enable firefighters to find ready-drilled holes. Later wooden systems had pre-drilled holes and plugs. When cast-iron pipes replaced the wood, permanent underground access points were included for the fire fighters. Some countries provide access covers to these points, while others attach fixed above-ground hydrants – the first cast iron ones were patented in 1801 by Frederick Graff, then chief-engineer of the Philadelphia Water Works. Invention since then has targeted problems such as tampering, freezing, connection, reliability etc.
