The invention concerns a water treatment method and installation, which consist in subjecting the water to be treated to membrane filtration ( ) to satisfy the requirement for a relatively high flowrate of water for ordinary use (UF), subjecting the water that has been subjected to membrane filtering to reverse osmosis filtering ( ) to satisfy the requirement for a smaller flowrate of water of improved quality (OS) and, outside periods of production of water filtered by reverse osmosis, sweeping the upstream face of the osmosis membrane ( ) with the flow of membrane-filtered water drawn off to be consumed.
