Apparatus for reverse osmosis using static pressure head including: reverse osmosis plant operable to produce a permeate and a concentrate (hereinafter referred to as a "brine") from a feedstock, the feedstock being supplied to the reverse osmosis plant via a feedstock conduit from a feedstock source; static pressure head means operatively associated with the reverse osmosis plant; permeate removal means in fluid connection with the reverse osmosis plant for removing permeate from the reverse osmosis plant; brine removal means in fluid connection with the reverse osmosis plant for removing at least some of the brine from the reverse osmosis plant to a brine removal location, and wherein the static pressure head means is provided by locating the reverse osmosis plant, the feedstock source and the brine removal location at relative altitude differences for generating a static pressure head in the reverse osmosis plant; the permeate removal means is located whereby, in use, permeate may be removed to provide a trans-membrane pressure drop sufficient for reverse osmosis of the feedstock across the membrane or membranes of the reverse osmosis plant; the location of the brine removal means with respect to the reverse osmosis plant and the feedstock is selected such that, in use, the brine removal means may be operated to provide flow of the feedstock sufficient for the generation of an operable fluid velocity across the membrane surface of the reverse osmosis plant.
