Open tanks are common in wild fires territories, like in Portugal, and
I'm probably in Spain and Greece.
Not in Australia.
They're used by helicopters and firefighters, who depend on them in
heavy mountainous regions, where it's impossible or very difficult to
get water.
Helicopters here use rivers, dams, not tank water.
Firefighting trucks here use tank water, and they have to pump it out
thought a hose to a nozzle, so contaminates can be a problem.
We're talking about water tanks of all sizes and formats, some of them
are really huge, which are only used for fight forest fires, so it
doesn't matter if they're contaminated.
For helicopters, they're marked with white and red stripes, so that
they can be easily spotted from the air.
Some of them rely on rain water to be filled, but most are refilled by
firefighters with river water or other sources.
Tanks here as a first option take rainwater. If necessary then water
would be trucked in. In remote areas with no population there are no
tanks so trucks would have to suck water from anywhere. In rugged remote
areas there are probably no roads!
Remote areas here with populations have extremely large tanks for
drinking water... that can be used for fire fighting. Extremely large =
at least a years water supply with no rain fall.

Greetings.
There are closed and open storage tanks, and I think is important to
differentiate them, specially those used by firefighters and rural
communities to fight wild fires.
The approved proposal for the key covered=* states "C. denote an
area such as an underground parking lot, a covered reservoir/cistern
or even such things as an aquarium (e.g., Kelly Tarlton's, Auckland,
NZ), when the covering is not a man-made structure that would allow
layer differentiation."
I would like to know what the community thinks about elaborate that
line a bit more, to include emergency storage tanks so that people
know it's ok to add covered=* to those structures.
Storage tanks around me are all covered, at least all the one I
remember are. This includes ones used or emergency fire fighting.
Uncovered ones would be very rare in my country due to the
possibility of contamination by drowned animals, dirt, dust, tree
leaves and tree limbs. There are probably regulations about them
being covered to prevent the breading of mosquitos! So would think
covered is part of being a storage tank at least here.
