<p>A system (10) for controlling flow of water in a building, comprising: inlet means (20) for connection to a water supply; outlet means (30)connected to the inlet means (20); valve means (40) for controlling flow of water from the inlet means (20) to the outlet means (30), the valve means (40) being configured to maintain a closed configuration to prevent flow of water from the inlet means (20) to the outlet means (30) in the absence of a genuine water demand being determined by the system (10); sensor means (50) for sensing a rate of flow in the system (10), the sensor means (50) being configured to provide an output representative of a rate of flow sensed; and control means (60) configured to receive the output from the sensor means (50) and open the valve means (40) to allow flow from the inlet means (20) to the outlet means (30) if the received output from the sensor means (50) exceeds a predetermined threshold rate; wherein the outlet means (30) comprises water storage means (80) for providing an initial supply of pressurised water to the building when the valve means (40) is in its closed configuration, the water storage means (80) comprising: chamber means (84) for storing water received from the inlet means (20); and pressurisation means (100) for pressurising water.
