As part of Kekaha Sugar's expansion program, three surface water diversions were constructed to address the failure of the well supply. In 1903, the Waimea Ditch was dug to divert water from the Waimea River to nearby fields. The success of this venture prompted the construction of the Kekaha Ditch in 1905, which carries water from an altitude of about 500 feet on the Waimea River to Kekaha. The ditch was completed in 1907 and the well water quality began to improve.
