A selective-capacity collection and drainage device having a first collection container, a second collection chamber and a common inlet valve characterized by a capacity selector and a common outlet valve connecting to each collection chamber. The common inlet valve consists of a common inflow tube, which connects via tubing to the catheter where bodily fluids will enter the selective capacity chamber. The inlet valve has a capacity-selector located between the common inflow tube and the multi-chambered container, such that bodily fluids are directed by the capacity-selector into one or all of the collection chambers via the divided inflow tube. Each individual chamber of the multi-chambered container is connected at its base to the common outlet valve. The common outlet valve consists of a divided outflow tube on top, which connects to each collection chamber, and converges at an outflow valve.
