A desalination system including a power piston slidably mounted in a power cylinder, a water pump for supplying pressurised water to a reverse osmosis unit, the water pump including a pump piston slideably mounted in a pump cylinder thereby defining a pump volume, and a coupling mechanism coupling the power piston to the pump piston, the coupling mechanism providing a relatively low mechanical advantage when the pump volume is relatively large and a relatively high mechanical advantage when the pump volume is relatively small.
