Abstract

Disclosed is a method and system for operating an on-board water supply and distribution system (1) of an aircraft (3) for supplying water, the system comprising a central water tank (7), at least one first consumer assembly (5), each of the at least one first consumer assembly (5) comprising a supply device and a buffer tank (37) and each of the at least one first consumer assemblies (5) being configured to supply fluid from the buffer tank (37) via the supply device. Each of the buffer tanks (37) of the at least one first consumer assemblies (5) comprises a treatment inlet for receiving a treatment medium into the respective buffer tank (37). The system further comprises a pump (21) having an upstream side (23) and a downstream side (25) and being configured such that it may operate in a supply mode and a reverse mode, and a high pressure conduit system (27). The central water tank (7) is connected to the upstream side (23) of the pump (21), and the high pressure conduit system (27) connects the downstream side (25) with the at least one first consumer assembly (5), with the conduit system (27) being configured such that the pump (21), when operating in the supply mode, is capable of supplying fluid from the downstream side (25) to the buffer tank (37) of each of the at least one first consumer assemblies (5), and when the pump (21) is operating in the reverse mode, it is capable of drawing fluid from the high pressure conduit system (27) towards the upstream side (23). The method comprising the steps of operating the pump (21) in the supply mode so that water from the central tank (7) is supplied to at least one of the at least one first consumer assemblies (5) wherein the buffer tank (37) of the at least one of the first consumer assemblies (5) is filled to a predetermined fill level, providing a treatment medium to the buffer tank (37) via the treatment inlet so as to mix with water in the buffer tank (37) to form a treatment solution, and operating the pump (21) in the reverse mode so that the treatment solution in the buffer tank (37) of the at least one of the first consumer (5) assemblies passes through a part of the high pressure conduit system (27) and the upstream side (23) of the pump (21).
