I would not create a special page for this but just enhance the
current wiki about man_made=pipeline (in type=water section).
If I introduce a new tag, a new tag descriptive page is mandatory.
If a page explain what is a pipeline system, of course I would improve
it without create a dedicated page about surge tanks.
But it doesn't seem to exist: http://wiki.openstreetmap.org/wiki/Pipeline
Furthermore, such a tank should connect a drain (water supply without
pressure) - waterway=drain - to a pipeline (where water could be
pressurised) - man_made=pipeline.
In France EDF brings water to its plants firstly by surface or
underground drains, which often are not visitables because of large
amount of water running from bottom to ceiling of tunnels. Then a surge
tank protects these drains for excessive pressure they can't even bare.
Finally, water strongly fall down to valves + turbines through a
shielded shaft, several pipes prevent visitors to be flooded and they
may walk safely beside.
It would be good to explain that on wiki indeed.
Cheers.
