SU1821 : Water, gas, electricity?

taken 9 years ago, near to Downton, Wiltshire, Great Britain

Water, gas, electricity?
Water, gas, electricity?
A plethora of signs indicating appropriate pipes nearby. But which is which and what is the information telling us?
WO stands for 'Wash Out' and is a valve and outlet, usually identical to a fire hydrant, for allowing the water company to drain down a pipe for work to take place and to flush out water pipes after work has taken place.
SV stands for 'Stop Valve' and shuts off a length of water mains.
I am uncertain about the ZV signs - possibly 'Zone Valve'? ie can be used to connect or isolate two areas of water pipework from each other?
The medium sized white letters are top - the size of water main in inches, and lower the distance away from the post that the valves or outlet are in metres, I think. (Unless they are extremely large pipes of 3 or 4m diameter!)
The small figures are reference numbers used by the water company for their records and drawings.
Thanks to John Mills for all this detailed information.
