A rapid deployment containment tank includes an inflatable container and a self-contained compressed gas source. The container defines a liquid chamber and an open top through which a liquid passes into the liquid chamber. The container is shiftable between a deflated configuration and an inflated configuration. The container includes a flexible base wall and a flexible sidewall cooperating to define the liquid chamber. The sidewall projects from the base wall along an interface and includes an air chamber. The air chamber includes a plurality of tubular columns spaced apart along the interface. The compressed gas source is coupled to the container and is fluidly connected to the air chamber to supply a compressed gas for inflating the container. The tubular columns are fillable with the compressed gas to cause the sidewall to lift upwardly from the base wall, as the container shifts from the deflated configuration to the inflated configuration.

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 liquid containment structure such as a frac pond has a perimeter wall; a floor liner bounded by the perimeter wall; and a platform underneath the floor liner, the platform formed of a plurality of mats laid edge to edge and whose upper faces collectively define a support surface. Related methods of use of the structure include installing the structure at a well site, and in some cases using the structure as a frac water pond. A drain channel may be defined in the support surface below a portion of the floor liner, with the portion of the floor liner extending downward into the drain channel.

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.

A leak preventing appliance and method for preventing liquid from leaking out of a damaged tank (2). The appliance comprises a suction head (4) to be pressed against an outer wall (5) of the tank under the effect of an underpressure generated by a vacuum pump (3). The suction head comprises a first chamber (6) and a second chamber (9) arranged around the first chamber. Each chamber has an opening (7, 10) intended to face said tank wall. The suction head is attachable to the tank wall under the effect of a reduced pressure produced in the second chamber by the vacuum pump. The first chamber is connectable to the vacuum pump via a valve device (8), which is configured to keep the first chamber connected to the vacuum pump when a reduced pressure produced in the second chamber by the vacuum pump is below a threshold value and to otherwise keep the first chamber disconnected from the vacuum pump.

A tank support base and skid apparatus provides a frame having upper and lower end portions, left and right side portions and front and rear portions. The upper end portion has a front row of tank receptive supports and a back row of tank receptive supports. A frame floor is spaced vertically below the tank receptive support. The frame has a peripheral fluid barrier that includes a front wall, a rear wall and side walls that form the fluid barrier around the floor, each side wall extending from the floor to a tank receptive support. First and second internal support members span from one side of the frame to the other side of the frame and each spaced between the front wall and the rear wall. Each tank receptive support includes horizontal beams that span from the front wall to the rear wall and supported by the internal support members vertical members that each connect with a horizontal beam. Inclined plates each connect to both a horizontal beam and a vertical member. Stops mounted on the beams separate a tank receptive support of the first row with a tank receptive support of the back row.
