A control device is provided for establishing a link in terms of control between the filling levels in the fresh water tank and waste water tank. The control device monitors the filling level in the waste water tank by associated sensors and controls the filling level in the fresh water tank as a function of a measured filling level in the waste water tank.

Abstract: An integrated domestic utility system is used to recycle grey water in a domestic house as a means to divert treated potable water away from non-potable uses, and in particular, toilet flushing. The system comprises a rainwater tank for storing rainwater collected from a roof top and a grey water tank to store grey water collected from a shower or bathtub. The rainwater is used to augment the grey water supply through a self regulating valve. Domestic water can also be used to replenish the grey water tank. A demand amount of grey water is pumped from the storage tank to at least one toilet tank. The system is controlled by a controller using pressure sensors and temperature sensors. The invention may include a solar heating circuit coupled to a domestic water heater. In one example of the invention, the system stores grey water in a bathtub and supplies it to toilet tank.

Abstract: Disclosed is an improved water-conserving toilet having independently flushable main and urinal bowls, a water storage tank for storing water for flushing the bowls, and a manually operable flush assembly for flushing the urinal bowl. The flush assembly includes a pump mounted within the water storage tank and a manually operable handle accessible external to the water storage tank. The pump is in fluid communication with the water storage tank and the urinal bowl for pumping a selected amount of water from the water storage tank to the urinal bowl for flushing the urinal bowl upon manual operation of the handle.

Abstract: An apparatus for disposing of body waste in a portable toilet is comprised of a container (100) and an associated hollow housing structure (14) which are adapted to be seated on a conventional toilet (B). Waste in container (100) is dumped into the toilet via a cable mechanism (154) on the intake stroke of a hand pump (170). A water intake hose (172) is manually lowered into the toilet water via a hose control handle (162) prior to the operation of the pump. While the container (100) is in a vertical dumping position, the exhaust stroke of pump (170) forces water siphoned from the toilet through a jet outlet (180) to clean the interior of the container (100). The waste and toilet water in the container (100) is discharged directly into the bowl without impinging the hollow housing structure. The container (100) automatically returns to its rest, or horizontal, position due to the action of a return spring.

Abstract: An auxiliary urinal retrofittable to an existing commode. The urinal is connected to a base plate which is placed between the base of the toilet and the floor and allows the urinal to drain liquid into the drain used by the commode. The urinal has a cup shaped head with a flush ring therein and a free standing semi-rigid drain line connected thereto and to the base plate to effect drainage. The semi-rigid drain line has limited travel segments to allow the user to manually position the urinal head to an optimum use position. In an alternative embodiment, the urinal is housed in a cover and placed against a wall.

Abstract: A device for converting a single volume cistern into a cistern allowing both low-volume and high-volume flushes. The device includes a hollow vessel inserted in the cistern and at least partially surrounding the flushing mechanism and water outlet. An opening at the upper end of the vessel for the entry of water and at least one selectively openable port comprising a hinged door having a retaining lever arm attached at one of its ends to the door are provided. The arm and door are movable between a first closed position to a second displaced open position. The vessel forms an open ended water column extending above and around the water outlet to exclude a portion of the water in the cistern from passing through the outlet while the door is in the first position for low volume flushes. The door and the lever arm move to the second displaced open position with the lever held and restrained by interaction with a standard water-level responsive part.
