A control system (15) controls a water supply from at least two separate input lines (3i-k) into a sector (1) of a water supply network. The control system (15) is configured to receive input flow information indicative of the water input flow (q.sub.i-k) through each of the input lines (3i-k). The control system (15) is configured to receive input pressure information indicative of the input pressure (p.sub.i) in at least one (3i) of the input lines (3i-k). The control system (15) is configured to receive pressure information indicative of at least one pressure value (p.sub.cri,m,n) determined by a pressure sensor (7m,n) within the sector (1). The control system (15) is configured to control the input pressure (p.sub.i) by controlling at least a pressure regulating system (13i) at an input line (3i) based on the input flow information from all input lines (3i-k) and based on the sector pressure information.

Methods, devices, and assemblies for controlling pressure in a supply grid are provided. The supply grid is suitable for supplying fluid to loads. The supply grid has first sensors for measuring the flow and/or the pressure of the fluid at first locations in the supply grid and a pump for pumping the fluid or a valve for controlling the flow of the fluid. The method includes: measuring the flow and/or pressure of the fluid at the first locations in the supply grid by the first sensors; predicting the pressure at the second location in the supply grid using a self-learning system based on the measured flows or pressures, wherein the self-learning system is trained to predict the pressure at a specified location in the supply grid; and actuating the pump or the valve at least also based on the pressure predicted by the trained system at the second location.

The invention relates to a water intake floating row cleaning system, including first vertical guide rail assemblies, a floating row, submersible pumps, water spraying assemblies, second vertical guide rail assemblies, floating fences and pumping assemblies, wherein the water spraying assemblies are communicated with the submersible pumps, and the submersible pumps pump the water of the river channel and spray the water towards the outside through the water spraying assemblies; and the floating fences stretch across the water intakes and float along with a water level, and the pumping assemblies are used for pumping out garbage blocked by the floating fences. The invention has the effect of efficiently cleaning the floating garbage at the water intakes.

The present invention discloses a device for flow control of fluid in pipelines to various utility fluid outlets like water taps and the like by blocking fluid flow from pipeline to said utility fluid outlet when the flow exceeds a predetermined flow rate. In other word, the present invention discloses an automatic fluid flow controlling device for restricting and/or stopping flow of the fluid medium running through the guiding means or the tubing system when fluid flow exceed a certain flow rate as well as stopping flow of the running fluid flow when fluid level in the vessel wherein the running fluid is being delivered reaches a certain height.

The invention related to liquid supply systems of buildings and constructions, where intake water line is connected to outer municipal, city, or local water supply. Also, liquid supply systems with two liquid sources, where intake liquid line is connected to outer water supply and simultaneously to the alternative water source, for example vessel filled with rainwater are known from the state of the art. Such systems can be used for cold as well as for hot water. The water supply system includes a liquid intake line, connected with at least two sources of wateran outer water supply line and an alternative source, made as a collecting vessel, and a liquid supply line, characterized in predominant water supply from the alternative source as the tank on the alternative source water supply line has the pressure higher than the pressure of the outer source.

Techniques for controlling water pressure at a plurality of water customer service sites are described. In an example, a first plurality of water service sites having water pressure values greater than a first threshold value are identified. A second plurality of water service sites having pressure values less than a second threshold value are identified. Valves controlling water flow to respective customer service sites within the first and second pluralities of water service sites are adjusted. The adjustments increase water pressure in the second plurality of water service sites to a pressure above a minimal target pressure. The adjustment maintains the water pressure of the first plurality of service sites above the minimal target pressure. In an example, groups of water service sites are associated with respective water mains and/or water pressure sensors. Information shared between groups may assist in adjusting water valves within the water system.

A water supply system for a plurality of water consumer units in an aircraft. The system includes a main tank configured to store a main supply of water, a main water pipe connected to an outlet of the main tank, and a plurality of water networks, each configured to conduct water from the main tank to at least one of the plurality of water consumer units.
