Client: Greco Ranch / Shasta RCD

Location: Kalamath River, Yreka, CA

Background: Two pumps (3000 gpm) draw water from a shallow backwater. The existing pumps were originally screened with large perforated plate tube screens requiring manually cleaning. Both original screens collapsed and new screens with self cleaning was needed to continue pumping.

Solution: ISI designed and installed a retrievable cone screen to a new pump intake manifold. The two pumps draw water from one self-cleaned screen. The mechanical brushes have prevented heavy algae accumulations and plugging. The intake screen and piped manifold can also be hinged out of the water during the flood season for pretection.
