A water closet system comprising a lavatory which is connected to a collection tank or mouldering chamber (2) over a discharge piping (3), and a liquid separator (4) interconnected in said discharge piping (3) adjacent and above the tank or chamber (2). The liquid separator (4) comprises an inlet pipe (8) having a widened bottom portion (13), an outlet pipe (9) preferably having a widened top portion (14) and a liquid container which sealingly encloses at least the end portions (13, 14) of said inlet and outlet pipes (8, 9). The diameter (D2) of the top end (14) of the outlet pipe (9) is equal to of larger than the diameter (D1) of the non-widened portion of the inlet pipe (8), and the said diameter (D3) of the bottom end (13) of the inlet pipe (8) is larger than said diameter (D2) of the top portion (14) of the outlet pipe (9). The discharge piping (3) may be connected peripherally to the inlet pipe (8) of the liquid separator, and the inlet pipe (8) may have several wires provided spaced round the periphery thereof and extending down towards the center of the outlet pipe (9) for guiding solid and semi-solid material received from the inlet pipe (8) to the center of the outlet pipe (9).
