A pile underground fluid storage assembly is disclosed which allows the labor of installing two systems to be shared, therefore reducing installation costs. The assembly includes a foundation pile for structural support of the building structure along with storage tanks for storage of fluids at various temperatures as required for building operations, with the tanks being located within the interior space of the pile. The assembly further reduces maintenance and repair costs by making the underground tanks accessible. It also prevents underground storage tank floating issues when groundwater levels exceed storage tank fluid levels.

Various anchors and methods for anchoring an underground storage tank are provided. The anchor includes a base and at least one retention mechanism connected to the base for retaining various configurations of hooks and straps for holding the tank. The retention mechanism includes an opening and a retention member that is configured to open or close the opening by displacing or collapsing said retention member. The anchor may include a composite base having a footing and a spine extending upwardly from the footing so as to define footing portions on either side of the spine. The footing and the spine may have a composite composition that includes a matrix material and a reinforcement structure embedded within the matrix material. The retention mechanism may be connected to the spine of the composite base for retaining a hook for anchoring the underground storage tank.

A meter box and lid unit has a meter box. The meter box has end walls and opposing side walls, an interior cavity and an opening. A lip extends along the walls. The lip has notches therein. The lid has a first portion and a separate second portion, the first and second portions covering the opening when the lid bears the lip. The first portion has a receptacle for receiving a transmitter. The first portion has retainers depending therefrom. The first portion is capable of moving from a first position to a second position, wherein when the first portion in the first position, the retainer and the notch are aligned and the first portion can be removed from the box. With the first portion in the second position, the retainer cooperates with the lip to retain the first portion on the lip. With the first portion in the second position, the second portion can be removed from the box while the first portion is retained thereon.

A complete fuel tank maintenance and cleaning system. This apparatus and method are capable of effectively cleaning an underground or aboveground storage tank by implementing a multi-stage filtration and removal system, and effectively removing contaminants from tank surfaces by using the product or alternative as a streamed cleaning agent within the storage tank.

A wellhead container for a geothermal system includes a base configured to engage a bottom of a recess within a ground. The recess extends vertically from the bottom of the recess to a surface of the ground, the base includes at least one first opening, and the at least one first opening is configured to receive a drilling string. The wellhead container includes a top configured to support a load applied by a drilling machine to the wellhead container. The top includes second openings, and each second opening is configured to receive the drilling string. The wellhead container includes a sidewall extending along a vertical axis between the base and the top. The sidewall is configured to position an upper surface of the top substantially flush with the surface of the ground, and the sidewall is configured to transfer at least a portion of the load to the base.

A hydrocarbon tank system environment corrosion inhibitor includes use of inert gas, preferably Nitrogen, to blanket ullage and interstice through the tank system. Blanket gas is provided via controller into coupling to access ullage. Blanket gas is provided upon fueling events to stabilize the pressure in the system and prevent entry of atmospheric air and water (vapor). Blanket gas may be continuously run into the ullage and/or other spaces in tank system. A controlled system allows for monitoring of pressures in the tank, and thereby identifies pressure events and even leaks in system due to unusual events, or general loss of pressure.
