Waste water collection arrangement

An accommodation unit having several floor levels and a plurality of room units at each floor level, each room unit having one or more plumbing fixtures with respective waste water outlets, the accommodation unit including a drain conduit leading from one floor level to another, and at least one waste water collection device associated with each floor level, each waste water collection device defining a chamber and including:

• a lid part,
• at least two inlet assemblies for delivering waste water from said waste water outlets to the chamber, each inlet assembly being at least partly above the floor level to allow waste water to be supplied to the waste water collection device above the floor level, and each inlet assembly being fitted to the lid part and being movably mounted to the lid part to enable its connection direction and position to be selectable, and
• an outlet assembly below the floor level for enabling waste water to pass from the waste water collection device to the drain conduit below the floor level while retaining water in the chamber to provide a gas-tight seal,
• and wherein each waste water collection device is mounted in a floor level and the lid part of each collection device is at substantially the same height as the floor level in which the collection device is mounted.
