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
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.
