A holding tank for a sanitary installation carrying a sanitary fixture receives fecal matter or wastewater from the sanitary fixture of the sanitary installation and has at least one inlet and at least one outlet. At least one suction float in the holding tank floats on the liquid therein and forms with at least one suction chamber opening downward through a suction screen into the tank. An extraction line connected to at least one suction pump opens into the liquid in the suction chamber for withdrawing the liquid from the holding tank through the suction float and for recycling the extracted water for use as a flushing fluid for the sanitary fixture of the sanitary installation.

A modified toilet tank that serves as a fold-down urinal and fully functioning standard toilet in one to provide a more effective and mess-free way for males to use the toilet when urinating. The present urinal toilet device is more sanitary to use, eliminates messes on floors and toilet seats, is easier to use, and conserves water.

Provided is a toilet system that can provide more detailed information about a use state of a toilet.

The toilet system includes: a detection unit (a door lock sensor, a seating sensor, a rotation sensor, a toilet washing switch, etc.) which detects a situation inside a toilet stall; and a control unit which determines, based on a detection result of the detection unit, that the toilet stall is in a vacant state or in an used state, and further makes at least one of a determination that the toilet stall in the used state is in a state immediately after a start of use and a determination that the toilet stall in the used state is in a state immediately before an end of use, and outputs a signal including determination results.

A system for monitoring flush valves is provided, including a plurality of flush valves arranged in at least one restroom of a building, each flush valve of the plurality of flush valves including a communication device configured to transmit flush valve data, and at least one controller in communication with each flush valve of the plurality of flush valves. The at least one controller is programmed or configured to receive the flush valve data from each flush valve of the plurality of flush valves and determine if a first flush valve of the plurality of flush valves is in need of servicing or replacement based at least partially by comparing flush valve data for the first flush with flush valve data for at least one other flush valve of the plurality of flush valves. A method and apparatus are also disclosed.

A method and apparatus are also disclosed.

According to various embodiments, a toilet bowl fill valve includes a valve body that has a cavity. A valve may be inserted into the cavity of the valve body. A handle may be integrated with the valve, and the handle may facilitate manual adjustment of the valve. The valve body attached directly to a body of a toilet fill valve.

A system for adjusting a timing of at least one flush valve based on demand is provided. The system includes a plurality of flush valves arranged in at least one restroom. The system also includes a network device configured to receive wireless signals, and at least one processor in communication with the network device and the plurality of flush valves, the at least one processor programmed or configured to: detect, based on wireless signals received by the network device, a number of mobile devices in the area; determine whether the number of mobile devices in the area meets or exceeds at least one predetermined threshold; and in response to determining that the number of mobile devices in the area meets or exceeds the at least one predetermined threshold, adjusting the flush time of each of the plurality of flush valves to an adjusted flush time.

A waste collection and disposal unit including a tank, a float-switch sensing system, and a grinder pump. The tank contains a contoured and sloping floor, a front section, a back section, two side sections and a one-piece lid, which is securable onto the other sections of the tank. The floor slopes downwardly from below the float-switch sensing system to below the grinder pump at an angle of at least about 5 degrees and is contoured in a downward curved arc between the front and back sections of the tank.

A stand-alone toilet system is powered by photovoltaic cells to operate a dehumidifier from which water is extracted from the atmosphere by dehumidification and used for flushing; an electronic compressor is situated in the toilet tank to compress air which is used with water in the flush cycle; a motorized or hydraulic hinge is utilized to open and close a toilet cover automatically which can be locked in place by an electromagnet securing mechanism to create an airtight seal in the closed position; a heating element and a UV lamp are situated inside the treatment facility of the toilet system to evaporate liquid and sanitize waste content therein respectively.
