Abstract: The installation comprises a disconnector tray (1) equipped with a sealable water supply inlet connected to a water source and with a water overflow unit, a balloon supplied with inlet bladder from the disconnector tray and connected to a water distribution circuit (10), a water treatment unit (11) placed between the tray and the balloon with bladder, a gray water storing unit (12) surmounting a unit (17) for electrocoagulation of a part of impurities contained in the water, and a unit (25) for filtering a coagulated solution. The tray is placed interior of a cupboard type enclosure. The installation comprises a disconnector tray (1) equipped with a sealable water supply inlet connected to a water source and with a water overflow unit, a balloon supplied with inlet bladder from the disconnector tray and connected to a water distribution circuit (10), a water treatment unit (11) placed between the tray and the balloon with bladder, a gray water storing unit (12) surmounting a unit (17) for electrocoagulation of a part of impurities contained in the water, and a unit (25) for filtering a coagulated solution. The tray is placed interior of a cupboard type enclosure. The water storing unit, the electrocoagulation unit and the filtration unit are placed above the tray. The tray, the water storing unit, the electrocoagulation unit and the filtration unit comprise a tank provided with a fluid supply inlet and a fluid discharge outlet. The overflow unit of the water storing unit and the electrocoagulation unit emerge in an overflow collector having a column type pipe. The overflow unit of the electrocoagulation unit delimits a fluid circulation circuit between the tank of the electrocoagulation unit and the overflow collector. The fluid circulation circuit is provided with a venturi adapted to allow the partial draining of the tank of the electrocoagulation unit under the action of a flow of fluid from the overflow unit of the gray water storing unit and the circulation of fluid inside the overflow collector. The fluid discharge outlet of the tank of the water storing unit is connected to the fluid supply inlet of the tank of the electrocoagulation unit by a first sealable connection unit. The fluid discharge outlet of the tank of the electrocoagulation unit is connected to the fluid supply inlet of the tank of the filtering unit by a second sealable connection unit. The sealable connection units include a unit adapted for sealing the connection units, and are placed partially outside of the tank. The installation further comprises a unit for piloting and monitoring the installation, and a pump. The piloting unit is placed partially inside the enclosure, is provided with a unit for emitting and receiving signals adapted to emit control signals. The pump is a piloted pump adapted to be controlled to leave the control signals, and comprises an operating mode in which the pump is configured to fill the tank of the water storing unit at a filling level of the overflow of the tank according to a function of control unit of partial draining of the tank of the electrocoagulation unit. The water supply inlet of the tray is disposed above the overflow unit, and is spaced apart from the tray at a distance of 5 cm so as to avoid the contamination of the water source. The overflow unit of the tray is equipped with a unit for connecting the overflow connector. The filtering unit comprises a sand filter. The water treatment unit comprises a water filtering unit, and a UV radiation emitting unit such as UV lamp associated with a unit for controlling UV radiation. The control unit comprises a photoresistor adapted to emit a signal when the resistivity of the photoresistor, according to the quantity of incident light emitted by the UV radiation emitting unit, is lower than a predetermined value. The tank of the water storing unit and the tray has a maximum capacity than the tank of the coagulation and filtration units. An independent claim is included for a process for the treatment and distribution of water.
