Year Installed: 2014

Client: Natomas Mutual Water Company / USBR / CDFW / CH2M / Record Steel Constructors

Location: Sacramento River, Sacramento, CA

Background: An critical unscreened on-river pump station needed replacement but could only be taken out of service between late fall 2013 and April 2014. A completely new facility was designed with and installed in the winter of 2014 without dewatering.

Solution: ISI's retrievable brush-cleaned cylindrical screen system was selected as the project's preferred alternative. This "on-river" screen design was fabricated off site and installed into the structure in a few days without dewatering activities resulting in overall cost savings.
The fish screen operate over a large range of river elevations can can be retrieved to the surface during flood and inspection events.
