And there seems to be a consensus for grouping all things where
firefighters can attach their pump under emergency=fire_hydrant.
Where there is a dedicated pipe/hydrant. Where there is a 'Static
Water Supply' then there are usually no formal fittings of any
description.
'Static Water Supply' you mean a place near a pond/lake/stream where no
prebuilt pipe is available and it is just a place where to park the fire
engine to get easy access
to the water by using there own hoses?
As far as I understood that will be the emergency=suction_point
But I think there are some issues left:
# Fire Water wells
A pipe connected not to a pond but to the groundwater.
Should be
water_source=groundwater
How to tag the water level (distance between water level and ground
level)?
water_level=6 (in meters) ?
Also there are water wells which have a water level below approx 8 m
and due to physics there is an additional pump needed. This pump is
integrated in the
water well at water level and is either driven by electricity or
external applied water pressure.
Humm water level is usually taken as the height reached by the water,
from the bottom of a well/dam/tank.
If you are sucking then you might get to the bottom .. so you would
need equipment to get to the very base of the water.
Must be a better term for this parameter? You want the dimension from
the pump point to the minimum (most distant height) water level.
You are right. I mean the distance between the ground level and the
water level. E.g. the water is 3 m below ground.
Does anybody have a better idea then water_level?
Background is: the lower the vertical distance between water level and
pump the easier it is to suck the water to the pump. Depending on the
pump and hoses (small airgaps at the hose connections etc) it can be
difficult to get water from vert. distances > 6/7m.
For firefighters this information is important, because if they have
more then one well to choose from they can use the one with the smaller
vert. distance.
water_volume=# (numeric value in m^3).
Around me capacity is stated in litres? So this could be a optional
unit.
I'd rather not see a small|medium|large value.
You are right, m^3 is shorter. But I don't mind if it's 75000 l or
75m^3.
Small, medium, large don't have to be, because it is not as well defined
as a absolute value.
I think it depends on the country, so the applications using this
information can convert from l to m^3 or small|medium|large
