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.
Claims19
A device for reusing greywater, comprising:
- a water feed adapted to supply greywater;
- a substantially vertically arranged collection reservoir adapted to collect the supplied greywater;
- a storage tank adapted to store water;
- a siphon device adapted to siphon water from the collection reservoir to the storage tank, the siphon device including:
- a siphon connection adapted to siphon water from the collection reservoir to the storage tank and arranged substantially in a vertically-central part of the collection reservoir,
- a filling valve, and
- a receiver device connected to the filling valve and adapted to receive supplied greywater;
- a water discharge adapted to discharge stored water to a water user;
- a sewer outlet;
- a control system;
- an overflow arranged on the top side of the collection reservoir;
- and
- a bypass conduit adapted to divert water to the sewer outlet.
A method, comprising:
- supplying water to a substantially vertically arranged collection reservoir;
- detecting a predetermined water level in the collection reservoir;
- operating a filling valve subject to the detected water level;
- siphoning water via a siphon connection from the collection reservoir to the storage tank, the siphon connection being arranged substantially in a vertically-central part of the collection reservoir;
- water overflowing at an overflow on a top side of the collection reservoir when the collection reservoir has been filled;
- detecting water overflowing at the overflow;
- and
- operating the filling valve subject to the detected overflowing water.
