Suction head is the right word in hydraulics.


> I think the water level will drop as large amounts of water are drawn off, so you may need the distance from ground level to the bottom of the water source.

For these cases and for ponds or rivers where the water level may vary, we can use:
min_scution_head=# (meters) when water level is high and the distance from ground level is to the minimum
max_suction_head=# (meters) ) when water level is low and the distance from ground level is to the maximum

Maybe integrated_pump=yes|bilge_pump|electric_pump|none ?

-1

+1


> 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

It is already explained in the proposal chapter "American Water Works Association colour scheme"

No, it isn't restrictive. For swimming pools you can place a node where you can park the fire engine (or where there is the SWS sign) with tags emergecy=suction_point + water_source=swimming_pool + water_volume + ...
