I know that this is slightly off topic, but it still applies none the less.
Urban survival/Water:
The need to do any of the following is very unlikely, but sometimes, crap happens.
In the case of water interruption, a residential hot water heater contains 40 or so gallons of drinkable water.
In the case of water contamination, do not use running water.
Turn off the main water supply to the house.
Turn off the electricity to the heater.
The pressure relief valve will allow the water out.
Most heaters have them at the top of the unit.
Open the valve and then look for the drainage nut on the bottom of the unit.
It won't taste that great because of heating, but it is drinkable.
The water inside the heater is already there, so there is no need to have water going into it at that point.
This avoids contamination.
In an urban environment, water outages are more common than one might think.
So is contamination.
We have often received warnings from local officials not to drink the water after a major heavy rainstorm or severe flooding.
Boiling water warnings are more common though.
It's always a good idea to keep 10 - 20 gallons of water handy, no matter how paranoid you might or might not be.
Cycle through 5 gallons a week, as water does have an expiration date, but is still drinkable, just not as fresh tasting.
NEVER drink from the bottle in a situation.
Sickness can be spread so easily by doing that.
A more unsavory place to find water is in the tank of a toilet. I don't recommend drinking from there, unless you are trapped for a long time in a
building for some reason.
Don't drink the water if there are any type of treatment tabs in the tank.
If the water is brownish, or metallic tasting, avoid it as well, it's likely contaminated.
Despite the discoloration inside the tank, it's most likely mineral deposits.
The tank is pretty much separate from the business end of the toilet.
Another source is vending machines.
While this seems obvious, those damn things can be like breaking into Fort Knox if you don't know what to do.
They are tough.
I suggest looking into that on your own.
I don't want to say anything about technique.
Last but not least, and this one is a stretch, I admit it, but a freezer can supply water.
As long as there is electricity, leave the door slightly ajar, and condensation will build, and ice up.
It tastes like musty socks, but it is viable.
