Abstract: The invention relates to a device for throughfeed of greywater to a water user, including a housing for receiving therein greywater supplied via a greywater feed, a first flush pipe extending downward from the housing and connected directly to a sewer outlet, and a second flush pipe extending downward from the housing and connected to a water user. The invention further includes a greywater system provided with such a device and method for applying same.

Abstract: A device for reusing greywater includes: a water feed for supplying greywater; a collecting reservoir for collecting the supplied greywater; a storage tank for storing water; a siphoning device for siphoning water from the collecting reservoir to the storage tank; a water discharge for discharging stored water to a water user; a sewer outlet; and a control system. A method of siphoning water includes: supplying water to a collecting reservoir; detecting a predetermined water level in the collecting reservoir; operating a filling valve subject to the detected water level; and siphoning water via a siphon connection from the collecting reservoir to the storage tank.

Abstract: The present invention relates to a system for reusing water, comprising: —a mains system which comprises at least one conduit for transporting water and monitoring means adapted to measure changes in an electrical parameter of the conduit; —a storage tank for storing supplied water; —a water discharge for discharging stored water to a water-consuming unit; and—a control system adapted to control the supply of water to and the discharge of water from the storage tank subject to the changes in the parameter measured by the monitoring means. The present invention also relates to a mains system applied in such a system, and to a method for monitoring such a system or water mains system.

Abstract: The present invention relates to a device for reusing greywater, comprising: a water feed (2) for supplying the greywater to be reused, a storage tank (4) for storing the greywater, a water discharge (6) for discharging water stored in the storage tank to a water-consumer (8), and a heat exchanger (10) for extracting heat from the supplied greywater. The invention also relates to a method for reusing greywater using such a device.

Abstract: The present invention relates to a method for processing greywater, comprising the following steps:—supplying water to a reservoir of a greywater device;—collecting the supplied water in the reservoir;—conducting water out of the reservoir to at least one reservoir of a water consumer;—monitoring the water quality; and—flushing the water from the reservoir of the greywater device and/or the reservoir of the water consumer into a sewer drain when the water quality drops below an acceptable level. Furthermore, the invention relates to a control system for controlling a greywater device, a system for reusing greywater, comprising a greywater device and a control system, and a greywater consumer, in particular a toilet, which is connected to such a system.
