The facility now consists of two rotary drum screens, each 4 feet in diameter by 12 feet long. The drum screens are constructed of 4.5-12 woven wire mesh (1/8-inch openings).
The bypass entrance channel is a full-depth, 18-inch wide rectangular channel that is 10.5 feet long. An adjustable weir gate at the end of this channel controls flows that then drop into a 3-foot wide by 8-foot long downwell. Bypass flows are then conveyed to the Naches River through a ~15-inch diameter PVC pipe for 5 feet to the river.
