Spanning eight miles from the Columbia River Gorge into northeast Oregon’s Umatilla Basin – home to some of the state’s most productive farmlands, the East Irrigation Project focused on decreasing the strain on underground aquifers by providing farmers with a secondary water supply. The East Irrigation Project taps into the Columbia River east of Hermiston and runs approximately eight miles south to Despain Gulch, providing water to over 26,500 acres of farmland.

We managed all three of the East Project work contracts Under the second contract, EID Welded Steel Pipeline, our crews installed 3,600 LF of owner-supplied 78” welded steel pipe and 150 LF of 66” welded steel pipe, utilizing trench boxes in areas where sloping required too much space for the deep pipe. Throughout the span of the pipe alignment, our crews encountered rocky ground, resulting in 4,500 CY of blasted and crushed material.
