Screen intake assemblies and related methods of fabrication and operation that improve both operational performance and structural strength. The screen intake assembly can include one or more screen portions that run substantially and continually along the length of the screen assembly to provide increase fluid intake and uniform flow. The screen intake assembly can comprise a central manifold having an exterior manifold screen portion to provide additional filtering capacity. The screen intake assembly can be used alone or in combination with internal flow modifier structures to increase fluid intake and uniformity. Internal flow modifiers can include a perforated flow modifier pipe, an internal flow modifier pipe, and/or converging flow modifiers. The screen intake assembly can include cleaning systems that operate continuously or on demand.

A mechanism levels and holds down lateral screens on a basin floor having drop pipes. Support plates fit underneath the lateral screens along their length, and bolts on the ends of these support plates can be used to level the screens. Anchor bolts are affixed to the basin floor using known techniques along and between the various screens. Hold-down bars then fit on these anchor bolts and are held by washers and nuts. Ends of these bars hold against the edges of the plates and the sides of the screens to hold them against the basin floor.
