The waste water output of an RO unit in a distillation system is conveyed to a still's condenser cooling coil to minimize water requirements of the system. A portion of the heated water fron the condenser, in one embodiment, is circulated to the RO unit inlet, where a temperature mixing valve maintains an optimum temperature for the RO inlet water by mixing feed water and condenser output water in the desired proportions.
