A flexible and inflatable tank for the supply of potable water that is made of a strong, rigid and flexible material and is designed to incorporate a thin, flexible inner bag that is made of materials that comply with standards for the storage of potable water. The tank is made of a rectangular sheet, a pair of walls, and one or more openings and is shaped in general like a closed, round, oblate cylinder with two side walls.

The present disclosure relates to a soil completely-covered tank system with a built-in valve chamber. The valve chamber includes a spherical tank body, a valve chamber, and a channel; an exterior of the spherical tank body is completely covered with soil, and the spherical tank body is supported by a stand column and is arranged on the ground, such that a gap is formed between the bottom of the spherical tank body and a ground foundation; the valve chamber is arranged between the spherical tank body and the ground foundation; a top opening of the valve chamber is connected to the bottom of the spherical tank body by means of a first connecting structure.

A container assembly comprises a container and a base and is configured to be transported horizontally to a work site where it is raised to a vertical working orientation. A hoppered container floor directs material to a discharge opening in a center of the floor of the container. A plurality of chutes is fixed to the container assembly and each slopes downward and outward from a chute input, located under a central portion of the hoppered floor, to a corresponding chute output. A distributor assembly mounted under the discharge opening receives granular material from the discharge opening and directs same into any one of the chute inputs. When loaded on a gooseneck trailer the container extends over the hitch assembly providing increased volume and capacity.

A sealing system for a covered tank, particularly a fixed gas-sealing tank in a wastewater treatment system, includes a thrust ring positioned just inside the tank rim, secured to a series of radial beams for the cover. Preferably supported on corbels anchored to the interior tank wall, the thrust ring has an outwardly extending generally horizontal flange that overlies the edge of the tank rim. To this flange and to the top of the tank rim is secured a flexible membrane seal, around the periphery of the tank. The membrane seal is easily installed, reliable as a seal, and can be efficiently replaced when needed.
