Systems and devices for storing a fluid in a reinforced bladder is disclosed. A flexible bladder is configured to store the fluid. An exoskeleton is configured to conform to and protect the flexible bladder on all sides. The combination of the flexible bladder and the exoskeleton results in the reinforced bladder.

A system and method for an underground stormwater storage system which may comprise a pit, a structure, and a liner. The structure may be disposed within the center of the pit and surround by the porous backfill and wherein outlets are disposed on the crown of the structure. A liner may form the outer layer of the pit. A method for releasing stormwater may comprise capturing stormwater from a surface, containing the stormwater within a structure, releasing a volume of the stormwater from the structure and draining an additional volume of the stormwater from the crown of the structure from an outlet when the structure is capturing more stormwater than it is releasing.

A submersible, water circulation system for enclosed tanks such as used by municipalities, fire districts, and industries. The system includes a driving unit having a shell extending along an axis with a pump supported within the shell. The shell has at least one inlet and at least one outlet and is positionable on the floor of the tank with the outlet facing upwardly. The upwardly facing outlet is preferably a thin, upwardly facing, elongated slot and creates a thin, substantially planar discharge of water therethrough that is directed upwardly toward the surface of the body of water. The substantially planar discharge presents a very large surface area for its volume and induces water adjacent the outside of the shell of the driving unit to move upwardly with it toward the surface of the body of water.

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.

The invention comprises a float evaporation reduction apparatus and method of use thereof. Individual floats self-right, self-unstack, and/or self-move through elements of the float design, such as a wind redirection element and/or a stability element. In one case, floats use top-side ridges to redirect wind forces to form, interconnect, and/or stabilize a self-assembled monolayer of floats. In another case, floats use side friction/interconnection forces to stabilize adjacent floats. In another case, one float and preferably a spatially distributed set of floats gather localized information as to the surrounding environment, and/or communicate data and/or information back to a controller.

A tank wall connection includes a base having a base recess and a wall having an end positioned in the base recess. A grout is filled in the base recess around the end of the wall. A caulk is disposed at a wall joint between the wall and the grout. An epoxy layer is disposed over the caulk and the grout at the wall joint.

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.
