I did a search and didn't come up with anything quite about this...though some related threads...
Anyway, recently noticed that when I flew a NW A330 there were signs in the lavs with a picture of a person drinking the water and a lne through it (though despite this there were paper cups provided!) Meanwhile, on the AA 777 no such signs. I drank a cup of water on the 777 and am still alive to tell...
Is this a function of the different types of aircraft, different airline maintenance procedures? etc.

If I can give you a piece of advice, never drink any tap water on board an aircraft, whatever it's boeing, airbus, ATR, Dash, etc.....
The water tanks are rarely properly washed. I know that from time to time the maintenance crew put some "cleaning" tabs into the water tanks..... And think that one day the aircraft water tank is filled in countries where water quality is more than doubtfull and the day after in another one with other water which is taken from a water supply truck which was loaded who knows when and where !!!! I know in Switzerland for example the water tanks are emptied when the aircraft is staying long on ground to avoid icing (winter only) but who knows the procedures in other countries where icing temperatures is not an issue ???
I tell you once more, DO NOT DRINK TAP WATER ON A/C !!

While they are supposed to have potable woater inside them, you can never really trust the water inside the tanks. It isn't a good idea to drink it, but it should be relatively sanitary. Those cups in there are often so you can brush your teeth. Most airlines serve bottled water on board.
However there are some exceptions. Air New Zealand for example does frequently wash out the tanks, and when they serve you tea or coffee on board, it is made with water from the on board tanks. So sometimes it is safe, but airlines have to make sure that it is kept clean.
If you have never designed an airplane part before, let the real designers do the work!

When I worked at a line station, only Southwest flushed their water tanks overnight. Other airlines filled up the a/c tanks, but WN let them fill up and spill onto the ramp. Don't know if that helped clean the tanks out, but at least an effort was being made. Or the WN rampers liked wasting water!
At the end of the day, MX knows whats inside. MX doesn't drink the water. All you need to know.
Hahaha, I'd drink it to clean my tanks then, knowing the presence of diluted tabs ...
But yeah, it's always good precaution not to drink aircraft water as mentioned by both HBJZA and Doug_Or. You'd be in a more profitable way to ask for bottled water in an aircraft than tap water, both economically, and health-wise.

Quoting YOWza (Reply 6): Some moody bitch FA with AC on YUL-FRA told my mom to get her own water from the lavs when she asked for some to take some painkillers. Still can't believe the shit that goes on at AC.
Tell her to drink the water from the tap herself then.. Probably should've jot her name down and complain directly to AC.. That is one rude gesture from an F/A

Never ever touch the potable water on board the aircraft. Not to drink, not to brush your teeth, nothing. These tanks are never cleaned per spec and it doen't matter what airline and what type aircraft. These tanks do not get touched until a "C" check at a minimum and the cleaning solutions do not get a %100 of the tank. Once a bit of fungus gets into the tanks nothing will get it out. Add to that the very real possibility that at one time during the life of the aircraft some lav juice was pumped into the water tank by mistake or at the very least, handled by someone who has just handled lav solution or refuse on the same aircraft. While I have never heard of anyone die as a direct relation to the water on board, I do know of numerous situations of passengers getting violently ill because of it. More than likely you will get seeral illnesses on the same aircraft traced back to improper handling procedures. Bottom line, you never can tell so stay away...

Also, remember that the beverage makers for tea and coffee use the potable water supply, not bottled water. Also, it's only heated to a high temperature, but not to boiling point. So the tea and coffee you drink onboard is always made with potable water.

I used to drink the tap water on planes all the time--especially on 747s with the little "water fountain" next to the lavs. Sure, it didn't taste great, but it seemed easier than troubling the F/As for bottled water.
Then a few years ago I was on an AA flight and had an interesting conversation with the guy next to me, who worked in maintenance at the airline. Among other things, he told me to never, EVER drink the airplane water, and went on to describe the nasty things that grow in the tanks. That set me straight!

Two completely different systems. The lav servicing panels only services the lav tanks. Clear water is pumped in to the tank and the "blue disinfectant" is added through the toilet. The potable water service panel only services the potable water system. Both are self contained units.

That is why I said it may happen over the life of the aircraft and not on a regular basis. You want to tell me that no new-hire ramper has ever made a mistake in what port he was filling? Happens more than you would like to know. Also, The procedure calls for always handling potable water before doing the lavs. How many times do you think that rule has been broken and how many times were the lavs service on one aircraft and the agent handling that went on to handle water on the next without cleaning up.
Quoting Tod (Reply 13): Modern airliners with vacuum waste systems no longer use blue juice.
A. There are still hundreds of aircraft in service that do not have the vacuum system and still use the regular flush. B. The vacuum system still uses small amounts of solution and liquid to "rush" the waste through system. Otherwise things will get sticky real fast.

Has there been provable situations where the tank water has cause significant numbers of people to become ill on a flight? What about the water in the lavatory when you wash your hands or does the soap disinfect enough?

I know from personal experience (trust me) that at least 90% of all corporate A/C water tanks are not cleaned or serviced at all on a regular basis. At least on those A/C that are large enough to have thier own lavatory. The only time they are touched is when there is MX inspections or if someone on board mentions the water has runout in the lav.

Quoting N229NW (Reply 23):
I'm still curious about the coffee and tea, since almost all passengers drink some and it never seems to be a problem. If the water really ISN'T boiled, as LHR777 says, then that seems odd to me.
I'm being pedantic, but 'Boiling' is relative. The temperature that water boils at when at sea level is higher than the temperature that water boils at when in a pressurized cabin. Even if they did boil it onboard, it woudn't be hot enough to be sterile.
