From Stream to Field
Dating back to 1878, East Maui Irrigation Company’s 74-mile system of ditches, tunnels, siphons and flumes was an engineering masterpiece that shaped irrigation projects in Hawaii and the western United States. Water collected from East Maui’s watershed sustained HC&S sugarcane fields for decades and continues to supply water to Upcountry Maui residents and farms through deliveries to Maui’s Department of
Water Supply. EMI’s pioneering role was recognized in 2002 when its ingenious system was designated a National Historic Civil Engineering Landmark
