A sterile water generator (B) generates a stream of sterile water on demand. A water heater (130) heats incoming, unsterile water to a sufficient temperatu re to achieve sterilization of the water. The sterile water is then passed through a heat exhanger (110) which transfers excess heat from the sterile water to the incoming water. This reduces the energy consumption of the wate r heater and reduces the temperature of the sterile water ready for use. The sterile water is delivered to a site (A), at which the water is to be used, through a sterile water delivery pathway (C) to avoid recontamination of the water. A first portion (162) of the pathway is pre-sterilized by flowing ste am or hot water, generated by the water heater, along the pathway (C). A second portion (212) of the pathway is sterilized with a liquid antimicrobial from the site. The first and second portions of the pathway have at least one common leg (164).
