The vehicular water-dispensing method incorporates a water recovery process, a water STT process, and a discharge process. The water recovery process: a) converts water contained in a gas phase in the atmosphere into water in a liquid phase; b) initially treats the converted liquid phase water to remove microorganisms and other chemical contaminations; and c) transports the initially treated liquid phase water to the water STT process. The water STT process: a) receives and stores the initially treated (liquid phase) water from the water recovery process; b) subsequently treats the stored water with a final treatment to remove microorganisms and other chemical contaminations; and, c) transports the treated stored water to the discharge process. The discharge process: a) receives the water from the water STT process after the final treatment; and, b) controls the discharge of the water received from the water

A method for disinfecting water by UV irradiation in water supply systems in buildings, ships or the like with a water tapping point connected flexibly to a hose (1), in particular hand shower (1′), and a water tapping point mount (2) for receiving (21) the water tapping point (1) when not in use, wherein the UV radiation takes place at the water tapping point (1). The UV-irradiation is directed from the water tapping point mount (2) to the water tapping point (1) when the water tapping point (1) is deposited in the water tapping point mount (2). Furthermore, the invention relates to a water tapping point. Means are provided for UV irradiation (3) of the water guided in the water tapping point (1). The means for UV irradiation (3) are arranged in the water tapping point mount (2), and a UV radiation transmissive window is provided in the water tapping point (1) opposite to the means for UV irradiation (3) when deposited (21) in the water tapping point mount (2).

A system of supply valves according to the present invention may include a first and second supply valve, each of which is connectable to a terminal end of a water supply line so as to provide direct access to the water supply. The system may be disposed within a modular plumbing supply box, and the valves may be spaced from one another by a reduced separation, X.sub.1. Each supply valve of the system may further include a top portion and bottom portion that are interconnectable and which form a water-proof seal therebetween. The top portion may comprise ridges that cooperate with channels of the bottom portion when the two portions are interconnected to form passageways. The top and bottom portions may be positionally and rotationally locked to one another, for example, using a wireform clip and inserting legs of the wireform clip through the passageways.

The invention relates to a device and method to quantify the lead exposure of an aqueous feed to humans, remove lead from the aqueous feed, and identify the presence of lead service lines. The device includes an inlet to receive a lead-containing aqueous feed; an outlet to discharge a lead-depleted treated aqueous feed; and at least one cartridge containing sampling media positioned so that the lead-containing aqueous feed passes from the inlet and through the cartridge to produce the lead-depleted treated aqueous feed for discharge through the outlet.

The present invention discloses a heavy metal separating device and a parameter determining method. The device includes a plurality of pipe sections and a plurality of adsorbents; the pipe sections each include multilayer pipes; the plurality of pipe sections are connected end to end; each of the pipe sections is coated with one adsorbent; and the adsorbent is coated onto the multilayer pipes of the pipe section. According to the present invention, the adsorbents are coated onto the pipes and supporting plates, so that heavy metals are separated in the wastewater conveying process, the area occupied by wastewater treatment facilities can be greatly reduced, and heavy metal ions in the wastewater can be efficiently separated.

In order to make available water that is as germ-free as possible, the invention provides a water installation system (1) comprising an extraction point (38) and/or an outlet, wherein the water installation system has a direction of flow (D) towards the extraction point and/or towards the outlet, and comprises at least one chemical germ barrier (200) upstream of the extraction point and/or the outlet when viewed in the direction of flow, wherein the chemical germ barrier is selected in particular from the group consisting of at least one alkalinizing and/or oxidative material, silver, chlorine, and combinations thereof.
