A fiber reinforced polymer material lid or cover for a utility vault made from an unsaturated polyester thermosetting resin matrix, glass fiber reinforcement, an inorganic filler and an ultraviolet inhibitor. The lid or cover has a flat textured upper surface having a plurality of bosses having different heights extending above the upper surface and a bottom surface having an outer perimeter rim with a recessed interior cavity having a number of continuous support ribs extending through the recessed interior cavity from opposite sides of the outer perimeter of the rim to transfer load placed on the lid or cover and minimize deflection under the load to the outer perimeter rim.

A collection tank for mounting under a floor of a building for collecting water from an area under the floor comprises upper and lower tank portions removably securable by rotatable mating of tabs in cavities. Additionally, a pump platform of the tank is formed by a plurality of ridges which form therebetween a channel so that the water is collectable in the tank between the ridges. Furthermore, the upper and lower tank portions are separable, and a width of the top of the upper tank portion is smaller than a width of the open top of the lower tank portion such that the upper tank portion can be received in the lower tank portion in an inverted orientation, in which the collection tank is inoperable for collecting the water, so as to decrease a height of the collection tank.

A holding container includes a plurality of pre-formed, releasably interlocking, load-bearing panels configured to form an at least partially curved, load-bearing wall extending around the perimeter of at least one storage area capable of containing at least 100,000 gallons of liquids, solids or a combination thereof. At least one among the width and length of each panel is less than 102 inches in a non-load-bearing state.

An anchoring assembly and related system and method for facilitating the securing a holding strap to a storage tank and holding of the latter to the ground, comprising a base that is connectable to a top surface of the storage tank and an anchor that is reversibly secured to the base and positionable in a transverse direction of the storage tank to anchor a proximal end of the holding strap. The anchor includes a tightening mechanism being supported above the top surface of the storage tank by the base, wherein the tightening mechanism is actuable to move the anchor with respect to the top surface of the storage tank, thereby modifying a tension of the holding strap.

Support structures for electrohydraulic apparatuses in particular of electrical and hydraulic apparatuses of irrigation systems are disclosed. The support structure is configured to be applied to a buriable well for housing and protecting such electrohydraulic apparatuses. On predetermined portions of the support structure a plurality of holes are formed, and are adapted for receiving a corresponding plurality of support means configured to hold, preferably in a releasable manner, one or more electrohydraulic apparatuses. Also described is a buriable well for housing and protecting electrohydraulic apparatuses comprising at least one such support structure of electrohydraulic apparatuses.
