Hi,
It depends on what characteristics are important to you.
"water driven" is power transfer medium so pump:power_medium=water.
This
is not the energy source! It doesn't say if the water has
potential/kinetic energy due to gravity, or if it itself is being
pressurised by a powered pump (e.g. hydrostatic drive)
"integrated" is to distinguish from something else? What would be
alternatives to a pump being "integrated"?
"bilge pump" is about its function, so something like
"pump:function=bilge"
"in a well" is about its location so "pump:location=bottom_of_well"?
How about the type of pump? Centrifugal? Reciprocating?
And the medium that is being pumped? In this context it is probably
water but in general a pump could be used for all sorts of stuff.
Let me explain, what the idea of adding pump tags to hydrants in the
proposal is:
In Germany we have fire water wells whose geodetic suction head is > 7.5
m (in theory water can be
pumped up to a suction head up to 10.3 m (1013 mbar pressure, water temp
4 °C, but due to losses
real level is lower).
To allow the fire engines to pump water from those wells, one of two
types of pumps
are integrated into the well:
* Electric pumps
* Bilge pumps
Maybe bilge pump is not the right word for it, but dictionaries proposed
it ;)
For running electric pumps you have to bring a power source.
The bilge pumps are driven by water. So you have a second set of
couplings
to pump water to the pump and get it back into the fire engine's tank.
This
water will drive the pump. The well has a third coupling which outputs
the
pumped water.
The idea is now to add this information to the hydrants/wells that the
firefighters/whichever data
consumers can easily see if they have to setup an additional power
source (generator or fire engine)
before getting water.
If this is the case I personally would evaluate if there is a hydrant or
well nearby where the water
is more easy to access.
What about
pump=yes|electric|water_driven
This will need a whole proposal to get a comprehensive description for
pumps.
I think we should only use pump=yes for now and wait for a more
complete
document to be written.
I disagree, that would make the proposal useless. Then only wrench and
check_date would be left.
