Abstract: The present invention is directed to a clarifier for water treatment including a module. The module includes a planar inclined sheet; a plurality of vertically-oriented supports; and a tensioner. The at least one planar inclined sheet is tensioned between the plurality of vertically-oriented supports and the tensioner is configured to bring the planar inclined sheet to an even centerline.

Abstract: A cover for a liquid containment apparatus includes: a platform having a top surface, a first end, a second end opposite the first end, and two opposing sides that extend between the first and second ends. The cover also includes: a front wall extending down from the first end of the platform; a back wall extending down from the second end of the platform; side walls extending down from the opposing sides of the platform; and engagement members extending out from a bottom of the side walls in a lateral direction from the platform and which are configured to engage a surface of a substrate. The platform includes a plurality of holes, and the side walls include a plurality of notches that form a weir for distributing liquids. A liquid containment system is also included.
