A mobile handwashing system (1) includes a freestanding supply station (2) and at least one freestanding handwashing station (3). The supply station (2) includes a freshwater tank (4), which is fluidly connected or connectable to the at least one handwashing station (3) via a first freshwater supply line (5) and is fluidly connected or connectable to a freshwater supply system via a second freshwater supply line (6). The supply station (2) includes a wastewater or graywater tank (7) and/or a wastewater pump (23) which is fluidly connected or connectable to the at least one handwashing station (3) via a first wastewater line (8) and is fluidly connected or connectable to a wastewater disposal or wastewater treatment system via a second wastewater line (9).

This invention harvests abundant, highly usable washing machine rinse cycle water for irrigation and other uses. This is accomplished using two separate devices working together; it is comprised of a valve assembly (FIG. 2B), for diverting this rinse water to a collector and the collector (10) which improves the quality of the water, then distributes it. By closing a single valve (7) during the rinse cycle, the user is effectively watering the landscaping. The rinse water is regenerated during normal household washing so it is not dependent on rain. It does not use power nor does it depend on filters or storing water. It reduces the amount of city water required as well as reducing the volume of waste water generated.

A shower water collection device configured to capture pre-shower water which once full may easily be sealed to prevent contamination of the collected water until the water can be used for another purpose. A shower water collection device further including an inverted umbrella type funnel for increased surface area and enhanced water collection.

A safety device of a recirculating-water utilization system to be constructed in a specific area includes: at least one of a circulating-water monitoring unit configured to monitor a water quality of circulating water purified by a purifying unit, or a treatment-vessel monitoring unit configured to detect abnormality of treatment vessels constituting the purifying unit.

The present invention comprises a self-contained mobile living space that mimics the amenities of an entire residential property in order to affordably house individuals, particularly in urban environments. All living necessities are fused into one micro-living platform, independent of access to existing structures, land space, electricity, or sewage hookups, allowing landowners to rent out space with limited effort. The wheeled foundation allows the assembly to circumvent some of the existing urban building codes. In preferred embodiments, the various elements are configured in such a way that separate areas for sleeping, leisure, bathing, cooking, and gardening can be had atop a single compact space, with the use of exterior space maximized to heighten the sense of spatial availability for the occupant. The invention provides a new alternative for affordable urban housing, exploiting available residential land without the expense, permitting, or effort associated with permanent construction on a non-portable foundation.

The present invention relates to a water disposable system comprised of a connecting member having first side connected to at least one unwanted water source and one valve to control the flow of an unwanted water. A toilet water tank is connected a second side of the connecting member, wherein the water tank comprises: a strainer in a stand pipe; a two float system, wherein a first float is set at a minimum tank volume water line, and a second float set at maximum tank volume water line. A button is coupled with a second float allowing the intake of the fresh water from the fresh water pipe upon actuation. A transparent window or gauge is positioned on the front wall of the tank for determining the volume of water in the toilet tank.

A clean water conservation tank for a toilet providing a secondary clean water source to a toilet holding tank from a secondary holding tank mounted to a surface above and in fluid communication therewith. The secondary holding tank includes an outer container having an actuation body therein, a drain, a hollow puncture body attachable to the drain, and a portable internal container, or a substitute container such as a milk jug, removably disposed therein. The internal container has a one-way spring valve controlling the water level therein. Upon the engagement of the actuation body with the spring valve, the spring valve provides selective fluid communication between the internal container and the toilet holding tank. The puncture body, removably disposed within a cap inside the internal container, is used to puncture the substitute container for water flow through the drain and into the toilet holding tank.

The disclosed invention improves on portable toilets for use in hostile environments. The improvements also provide a mechanism for the portable toilet to interface with transportation devices to facilitate transport. The portable toilet is constructed to withstand wind and explosive forces to protect the user. Equipment is also installed in the portable toilet for user safety.

Disclosed herein is a device for facilitating siphoning of greywater (graywater) or gently used water. An adapter is designed to fit onto the end of a hose or tube. The adapter is manually held tightly or attached by friction to a spigot or faucet. The faucet is turned on and running water primes the hose. The adapter is then placed under the surface of a collection of greywater in a sink, tub, clothes washer and the like. Greywater is then allowed to flow to a garden, lawn, cistern or other place where the greywater can be put to use instead of shunting it into a sewer. The device includes a funnel-shaped portion and a threaded portion. The device is made from a pliant material such as a silicone rubber or plastic.
