A water containment apparatus includes a straight strut arrangement comprising a plurality of straight strut assemblies forming an alternating v-shape and inverted v-shape pattern; and a curved strut arrangement comprising a plurality of corner strut assemblies forming a desired curvature and connecting two straight strut arrangements to form a closed loop water containment system.

A refrigerator has a storage chamber opened and closed by a door and a water supply system to supply water to a water taking port disposed at the door. The water supply system includes a water tank and a plurality of connecting pipes. The water tank includes an elongated cylindrical shaped body and a cap configured to form a reservoir such that a section of the cap overlaps the body, a first port having a passageway integral with the elongated cylindrical shaped body, and a second port integral with the cap, the second port being aligned in a direction different from a longitudinal axis of the water tank. The connecting pipes include a first water line positioned in an opening of the first port in a direction different from the longitudinal axis of the water tank, and a second water line positioned in an opening of the second port.

An underground water-storage system that includes a sump having a base and sidewalls that cooperate to define an open-topped box that defines a reservoir, a plurality of plastic water matrices each defining a void space for receiving water, and a lid. The sump and lid are formed of a reinforced geomembrane material and include welds and are prefabricated in a location remote from an installation site of the underground water-storage vault more than two days prior to installation.

Devices, methods, and systems for filling reservoirs including but not limited to an apparatus comprising a first transition conduit assembly; where the first transition conduit assembly includes a first inversion chamber housing connected to a first transition conduit, and the first inversion chamber housing includes a frustoconical portion; the first transition conduit assembly is adapted to create a first inversion gap when positioned above an inlet of the water storage tank; where the apparatus may further include a second transition conduit assembly and the second transition conduit assembly is adapted to create a second inversion gap when positioned above the first transition conduit assembly.

A method of installing an Emergency Flow Restrictor Device (EFRD) on a pipeline without stopping the flow of fluid through the pipeline includes the steps of: assembling first and second face plates on a pipeline such that the first and second sealing face are in face to face, spaced relation; assembling a cutting device between the first face plate and the second face plate; assembling a valve body that has an access opening on a length of pipeline such that the valve body encloses the first and second face plates and the cutting device; installing an access valve on the access opening; operating the cutting device to sever the pipeline between the first and second sealing faces; retracting the cutting device and severed section of pipeline; and attaching a valve gate member of the EFRD to the access opening.

Heat trace system for heating vessels of a piping system comprises a main control system, a plurality of heat trace elements, and a plurality of wireless modules. Each heat trace element is adjacent to one of the vessels of the piping system and connected to an electrical power source of the main control system 16. Each of the wireless modules: (a) is connected to and powered by an associated heat trace element; (b) comprises an energy storage device connected to the associated heat trace element for storing energy from the associated heat trace element to power the wireless module; and (c) comprises an RF module for communicating wirelessly with the main control system via a wireless communication network. The stored energy in the energy storage device can be used to power components of the wireless module, even when no current is flowing in the heat trace element to which the wireless module is connected.
