An irrigation system for providing a continuous and controlled flow of a fluid. The system includes (a) a reservoir system having a main longitudinal axis and a plurality of containers of fluid； (b) a fluid transfer system in fluid connection with said reservoir system and includes at least one fluid transfer head, adapted to transfer fluid from one of said plurality of containers to an external tubing system； and (c) at least one connector between said container and said fluid transfer head. Each fluid transfer head has a mechanism adapted to linearly move each of said fluid transfer heads along said main longitudinal axis. Each container comprises a neck and a nipple. Each connector is reversibly coupled to said irrigation system and comprises: a lower section comprising two arcs, the distance between the centers of said arcs substantially equal to the distance between the centers of said neck and said nipple.
