To support essential farmland operations in Selah, Washington, the Naches-Selah Irrigation District project required replacing nearly a mile of outdated, above-ground wooden irrigation trestle with a modern underground HDPE pipeline to boost irrigation capacity. Navigating strict work windows during critical growing seasons, Tapani demolished the existing flume, installed over a mile of 36″ KRAH HDPE pipe and 7,900 feet of 33″ KRAH HDPE pipeline, constructed a new precast intake and screening structure, installed a 96” splitter manhole, and regraded and resurfaced over 2.5 miles of access road.
