Nevada Irrigation District’s Doty North Canal Siphon #1 Replacement Project, located in Placer County, involved the replacement of an existing raw water transmission siphon that was in poor condition and had reached the end of its useful life. As part of the Project, the existing 24-inch raw water siphon crossing over Doty Ravine and Sailors Ravine was removed and replaced with a new 350-foot long, 36-inch-diameter welded steel inverted siphon pipe. The new pipe will convey Doty Ravine North Canal raw water across Doty and Sailors Ravine consistent with the District’s approved masterplan design flow rate of 34 cubic feet per second (cfs).
Construction began on December 1, 2020 and was completed March 24, 2021.
