Abstract: Systems and methods for processing wastewater into a flushing fluid are described, in which wastewater flows into a holding tank from one or more restroom fixtures. A vacuum distillator can be coupled to the holding tank, and a heater can be configured to heat at least a portion of the wastewater in the vacuum distillator to produce a vapor. The vapor can be condensed by a condenser fluidly coupled to the vacuum distillator to produce a distilled stream. The stream can either be fed into a tank or passed to one or more restroom fixtures.

Abstract: A system is disclosed that advantageously monitors a status of a relief valve coupled to a water heater or other pressure vessel. By monitoring the relief valve, the system can limit the energy and water wasted resulting from the relief valve's failure. The system can have first and second sensors that monitor a temperature and pressure within the relief valve, and a water flow from the relief valve, respectively. If the temperature or pressure within the relief valve exceeds predetermined thresholds, or a water flow from the relief valve continues for greater than a predetermined interval, the system can restrict a flow of gas, electric current, or water to the water heater.

Abstract: Systems and methods for monitoring and controlling water consumption in a water-based system are disclosed using one or more sensors for generating signals indicative of the operation thereof. One or more interface modules are provided as breaker circuits for receiving the generated signals, and a fluid control device is operable for limiting the water consumption. A motherboard receives the interface modules and provides communication therebetween for information processing. Signals from the various sensors are supplied to a controller, which provides signals to status indicators, and also operates to provide alarm signals via network interfaces to remote locations. In an alternate embodiment, a water monitoring system is designed to shut off the water supply to the water device and to shut off either the electrical supply or the gas supply to the heating unit of the water device in response to sensing a malfunction through one or more sensed parameters.

Abstract: Various embodiments of a cartridge for regulating a fluid flow are described that include an upper housing, and an insert that is user-removable from the upper housing. The cartridge can include one or more valves that are biased in a closed position to prevent odors from escaping the cartridge. The cartridge can also include a fluid trap that is at least partially disposed within the cartridge or fluidly coupled thereto. An ultraviolet light can be inserted within the cartridge to disinfect a fluid passageway of the cartridge.
