Rehabilitating Irrigation Systems from the 20th Century for the 21st Centuryby Gary L. Parker, SFC Engineering Co, Phoenix, United States,
Abstract: Irrigation projects were begun in the southwestern United States in the late 1800's. These projects were increased and modified during the 1900's and have become the lifeblood of reservations and many rural communities. In order to beneficially use and protect land and water resources, rehabilitation of the irrigation and drainage systems has to be completed economically and competitively. Planning for successful rehabilitation includes evaluation of existing delivery and irrigation systems and on-farm irrigation practices, and continued operation and maintenance of the delivery and irrigation systems. These components of rehabilitation will be discussed for an irrigation project begun in 1867 that now irrigates over 80,000 acres in Arizona and California.
