Water supply system comprising a venturi pipe

An aircraft comprising:

• a water supply terminal;
• and
• a water supply system comprising:
• a first pipe;
• a second pipe;
• a third pipe;
• a water reservoir;
• and
• a Venturi pipe having a first Venturi nozzle terminal, a second Venturi nozzle terminal and a branch arranged between the first and second Venturi nozzle terminal,
• wherein the second Venturi nozzle terminal is connected via the first pipe to the water reservoir,
• wherein the first Venturi nozzle terminal is connectable to the second pipe to fill the water reservoir,
• wherein the branch is connectable to the third pipe to supply water to taps,
• wherein the Venturi pipe is configured such that during a filling operation water flows through the Venturi pipe from the first Venturi nozzle terminal to the second Venturi nozzle terminal when the water reservoir is being filled, and during a supply operation water flows through the Venturi pipe from the second Venturi nozzle terminal to the branch during a water supply procedure,
• wherein the water supply terminal is connected to the water supply system in such a way that the water supply system can be filled with fresh water during the filling operation via the water supply terminal,
• wherein at least one tap is arranged downstream in the third pipe during the water supply procedure,
• wherein the branch of the Venturi pipe is connected downstream via the third pipe to the water reservoir during the water supply procedure so as to form a circulating water circuit, wherein at least one tap is arranged between the branch and the water reservoir.
