Hello,
I would like to know about the lavatories of the A320 and A321. Specifically, how much water does the tank that supplies the basin carry? ( In litres please or dimensions of the tank)
Would really appreciate an answer from all of you tech experts 
Thanks

The water tank of the A320 and all other planes, don't just supply water to the lavatory, it also supplies the water to the coffee makers and galley sinks. As for the original question. According to my company manual the A320 tank holds 53 US gallons. Which is approximately 200 liters.

Not Airbus, but the 737NG has a 62.1 gallon tank that uses different standpipes to decrease capacity. My airline uses standpipes that give the -900/60 gallons, -800/50 gallons and -700/40 gallons.

The 320/321 both hold 200 liters, I believe the one in the 319 is 150 liters. It can be real useful checking the actual water level when you are at a max weight for the loadsheet

Nothing's worse then flying the same registration twice, except flying it 4 times..

Counting kids would be a far quicker way of shaving weight than the water level.

So the coffee water and the toilet are using the same water - which means the toilet uses water of drinking water quality?

Yes, on aircraft with vacuum type toilets, potable water is used for everything.

We already use child weights on every loadsheet!

Isn't that weight already accounted for in the APS weight?



You are said to be a good pilot when your take-off's equal your landings.

You mean that 737 NG is fitted with same tank but these standpipes act as overflow pipes to change the capacity of the tank.
I am wondering why you don't fill the tank according (approximately) the number of passengers by checking the water level indicator while filling the tank

Yes.

I imagine the primary reason is consistency and the K.I.S.S. principle, if you fill the tank to overflow the amount in the tank is assured. Also, the level indicator is a series of LED's located in the aft galley, a very inconvenient location if you were to try and use it to fill the tank to a certain level.

It also means you don't need to top up the tank for every flight, which saves time and man-hours during turns.



You know the gear is up and locked when it takes full throttle to taxi to the terminal.

This comes around every couple of years. They give a graduate a job to save money, and he decides to half fill water tanks. It works for a while, then an aircraft departs with a half full tank on a 12hr flight, and diverst to fill it up. All the years savings gone in an hour.

On our European flights we fill every water tank full in LHR, where the water tanker is owned by us, then never service the water (or toilet) tanks at the European turnround (where we pay someone else to drive the water truck). This saves money over flying around with half full tanks, and servicing every time.

On some a320 aircraft you can preselect the water qty on the CIDS panel at 1L. But not every flight attendant knows this, and they press the 25pc button, then complain when the tank is only 25pc full!

By the way, although the water service panel is in the same place on all A319/320/321, the tank is moved.
On A319/321 it is at the rear of the rear freight, just above the service panel.
On the A320 it is at the rear of the FWD freight hold.
