Hose Layer Unit
Hose layer units (HLU) house large-capacity high-pressure hose wagons and respond to incidents where hydrants or other water sources are not close enough to the fireground and firefighters are hampered by a lack of water. The vehicle will lay out its hose at the nearest hydrant or open source, and then drive to the fireground with the hose laying off the back. Upon arrival it will connect to a standard appliance to supply it with the water needed for the firefighting operations.
The HLU may also be used to remove large amounts of water from an incident ground, such as a flood.
There are four HLUs, registered between 2010-2011, stationed at strategic locations across London, at Barking, Kingston upon Thames, Beckenham and Harrow.

Famous quotes containing the words hose, layer and/or unit:
“I must comfort the weaker vessel, as doublet and hose ought
to show itself courageous to petticoat.”
—William Shakespeare (1564–1616)
“A revolution is not the overturning of a cart, a reshuffling in the cards of state. It is a process, a swelling, a new growth in the race. If it is real, not simply a trauma, it is another ring in the tree of history, layer upon layer of invisible tissue composing the evidence of a circle.”
—Kate Millett (b. 1934)
“During the Suffragette revolt of 1913 I ... [urged] that what was needed was not the vote, but a constitutional amendment enacting that all representative bodies shall consist of women and men in equal numbers, whether elected or nominated or coopted or registered or picked up in the street like a coroner’s jury. In the case of elected bodies the only way of effecting this is by the Coupled Vote. The representative unit must not be a man or a woman but a man and a woman.”
—George Bernard Shaw (1856–1950)
