An outdoor water service system is described. The system is primarily for providing water for outdoor applications in cold weather, such as flooding outdoor rinks but may also be used for other watering applications in warmer weather. The system includes a source of water connected to an underground hydrant with an above-ground hydrant valve and a heated enclosure with a floor and an opening in the floor through which the hydrant valve extends. The enclosure includes a hose, a heater, a water conduit extending from the hydrant valve to the hose, a first door for accessing the hydrant valve from outside of the enclosure and a second door for accessing the hose.

An abnormal consumption detection system is provided with remote valve control for a distributed water infrastructure. The system may comprise an electronically controllable valve, a remote communication transmitter, a remote communication receiver, at least one sensor for measuring water flow information associated with the distributed water infrastructure, and at least one processor. The system may determine from the water flow information obtained from the at least one sensor a potential abnormal consumption associated with the distributed water infrastructure. The system may automatically close a valve, without human intervention, when the potential abnormal consumption is determined. The system may transmit, via the remote communication transmitter to a remote administrator, alert information about the potential abnormal consumption to enable an administrator to decide based on the transmitted information whether to reopen the valve. The system may receive from the administrator via the remote communication receiver a control signal to reopen the valve, despite the information about the potential abnormal consumption, and reopen the valve.

A water service supply assembly includes a water supply line with a stop valve. A lid is supported relative to the stop valve. A first switch is adapted to detect movement of the lid and a second switch is adapted to detect if a body is moved relative to the stop valve.

A flushing station for a ring-pipe or series-pipe system, comprises a cold water port for connecting a cold-water pipe, a hot water port for connecting a hot water pipe, and a waste water port, wherein the cold-water port and the hot water port are fluidicly coupled to the waste water port. The cold-water port, the hot water port and the waste water port are assigned to a bottom side of the flushing station.

A system is provided for differentiating between water usage of multiple water consumers using a common distributed water infrastructure. The system receives from a water sensor that is upstream of a plurality of appliances, signals indicative of water usage, and constructs from the signals a plurality of water event profile signatures. The system associates, based on differences between similar water event profiles, at least one water event profile signature with a first water consumer and associates a second water event profile signature with a second water consumer, and stores the water event profile signatures for the first water consumer and the second water consumer. The system constructs current water event profiles reflecting subsequent water usage in the distributed water infrastructure, and attributes a first current water event profile to the first water consumer and attributes a second current water event profile to the second water consumer.

A dialysis service box for centralized control and plumbing arrangement of a dialysis machine is disclosed. The dialysis service box includes a plumbing arrangement with a warm water inlet and a cold water inlet in fluid flow communication with a temperature mixing component. The thermostatic mixing component mixes the cold water and the warm water to produce mixed water maintained at a predetermined temperature between the temperature of the cold water and the temperature of the warm water. The dialysis service box can be universally installed to operate, control and adjust any dialysis machine that requires supply connection, waste connection, backflow preventer, thermostatic mixing component, a trap primer, or any combination of the foregoing.

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.
