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 fastener for attaching an identification placard having a post to a lid for a utility vault from a single side of the lid, the fastener includes a body portion for positioning within a hole in the lid, the fastener having tabs for retaining the fastener to the lid and lobes for preventing over insertion of the fastener into the hole in the lid and a bore extending through or partially through the body portion for receipt of and friction retention and/or mechanical interlocking of the post of the identification placard.

A tank (e.g., an underground storage tank), and manufacturing methods therefore, may include a tank body having an exterior surface. A component is mounted on at least a non-planar portion of the exterior surface of the tank body using an adhesive (e.g., an MMA adhesive). For example, the component may be positioned on the non-planar portion of the exterior surface of the tank body after application of adhesive and pressure may be applied to maintain the position of the component on the non-planar portion of the exterior surface of the tank body as the adhesive is cured. The pressure may be removed upon curing of the adhesive and formation of a structural bond may occur at the adhesive interface between the mounting surface of the component and the non-planar portion of the exterior surface of the tank body.

Individual honeycomb shaped modules used in an assembly for underground storage of storm water and other fluid storage needs. Modules are assembled into a resultant honeycomb shape for maximized structural strength and material use efficiency. Internal hexagonal or square shaped modules are assembled and encased by external hexagonal or square shaped modules. Internal adjacent modules are in direct fluid communications with one another through a channel-less chamber. Internal hexagonal or square shaped modules drain into external hexagonal or square shaped modules chamber where fluid is either stored or drained. Assemblies include various top and side pieces along with access ports for entry into said assembly.

A system and method for monitoring liquid tanks that includes a submersible sensor within the tank below liquid surface. The system may also include a secondary sensor to determine ambient conditions, and a controller to determine when changes in liquid level are due to ambient events, or potential breach of system. A calibration rod may be used to monitor displacement of liquid in the tank and calibrate system to determine changes in height of liquid level.
