Plane Water Tanks

Mon May 27, 2002 4:21 am

While looking at a cut-out diagram of a A300, there was a label showing water tank, what is the water tank used for?

My guess would be for the people on board, for drinking, cooking and the lavatory.

generally, YES..but not always.

The Il-62/62M uses a system of interconnected water tanks and transfer pumps for weight and COG trim

The water is mostly used for the galleys (making the tea/coffee) and for washing hands in the toilets. - (how else did you think it got there Big grin), and on some a/c they have those water points where you can help yourself, altho I wouldn't recommend drinking a/c water, those tanks are not the most hygenic places. I would only drink bottled water on a/c. I have spoken to engineers who point blank refuse to drink anything that is made with water from the a/c tanks, and when I asked why, they said 'have you ever seen the inside of one, and do you know how they clean them ?' That was enough for me.

Don't worry, i ain't never drinking any sort of water in plane unless it's bottled or it's my own!  Smile

Why is it so dirty in the tanks anyway?

The water gets stagnant in the on board tanks. I would think it closer to a bacteria growing experiment. BIG money was spent when the C-5 B models came out to have an on board potable water system. I was told seriously that it was modelled after a Winnebago RV system. It froze up in flight, froze on the ground in cold weather, all kinds of problems. We have now gone back to a very high tech aerospace solution, 5 gallon water coolers and ice!

Hey John M.
4f31138 and 4f31139 are blue print numbers for the nose gear kneel stop assembley. Those numbers have been stuck in my head since 1987. I think I started on ship #0102 and went all the way to the last one #o131. I had to use a power feed drill just to penetrate the 300 k.s.i steel. Those things are so hard they'll out last the rest of the airplane by at least a hundred years. I just hope it doesn't take that long to get those numbers out of my head.  Smile

Also, another reason not to drink the water, is that some aircraft fly international. When flying from the Mexico to the USA (for example!), many people would get the runs from drink anything with ice, or the water. I dont know if this holds true anymore, but the stagnancy of water still does. At least the water going INTO the tank is fresh.

Aircraft potable water systems are cleaned periodically with a bleach/water soulotion and then flushed with fresh water. Still, I refuse to drink anything coming out of those systems.
