An apparatus includes a floor having an impermeable material, where the floor has multiple edge portions and each edge portion corresponds to one edge of the floor. The apparatus also includes multiple wall sections configured to form multiple free-standing walls around a perimeter of the floor, where each of the multiple walls corresponds to one of the edge portions. The apparatus further includes multiple brackets, where each bracket is configured to fit over one of the multiple walls after the corresponding edge portion of the floor is draped over the wall. Each bracket is configured to fit against sides of the wall so as to hold the corresponding edge portion in place.

A method for the construction of an improved tank base. A tank base is constructed for protection against accidental spills and/or leaks associated with a tank battery. The improved tank base comprises at least one part of a suitable substrate, which allows for the adhesion of an elastomer such as polyurea. Polyurea is preferably applied using a spray device which yields an average coverage of about 50-80 mils, and most preferably 60 mils. If more than one substrate is used, one or more substrates can be bound together with a fastening system. Once pressure is applied in the form of weight, the fastening system can be removed, resulting in an improved tank base having at least one seam and impervious to the fluid of the tank battery.

A modular fluid containment system has wall segments that are joined at angled corners to form a closed wall. A membrane spans the closed wall and is connected to the closed wall with membrane attachment members. In some embodiments, a truss may span the closed wall and support a second membrane that protects impounded liquids from the environment.

The application relates to a liquid containment assembly (200) for a wind turbine (10), comprising: a support (202) for supporting wind turbine equipment (220); and a flexible container (300) suspended beneath the support (202). The flexible container (300) is arranged such that it is moveable between a collapsed position, in which the liquid containment assembly (200) has a first depth (D1), and an expanded position, in which the liquid containment assembly (200) has a second depth (D2), the second depth being greater than the first depth.

A water heater includes a leak detection system that is integrated with the water heater. The leak detection system includes a channel that extends circumferentially around the water heater. In one example, the channel is built into the water heater. In another example, the channel is formed by a sensor bracket that is coupled to the water heater. Further, the leak detection system includes a sensor assembly that is configured to detect water that leaks from the water heater. The sensor assembly includes a leak sensor and/or a wicking tube. The wicking tube is disposed around at least a portion of the leak sensor. Further, the wicking tube is disposed in the continuous channel and extends circumferentially along the water heater to create a circumferential area of leak detection around the water heater.

A rectangular or square fluid container having a baffle assembly configured to fit inside an interior volume within the fluid container. The fluid container is capable of being pressurized and has a number of valves or ports on a top wall thereof, which valves or ports allow for the fluid container to be filled with a fluid, for the fluid container to be pressurized, and for the removal of fluid from the fluid container.
