Self-Cleaning Screen for Wwater Supply Ssystems

The screening device described below was developed to remove foreign material from the irrigation water going into the overhead lines at the Forest Service nurseries in Region 6 (Wind River in Washington and Bend in Oregon). The water at both places would be unusable for overhead irrigation without screening of filtering. At Bend it is taken from an irrigation ditch and carries weed seeds, algae and other debris common to such ditches. At Wind River it is taken from a stream that has a great variation of flow between low water and flood and carries a variety of material from silt and algae to sticks and leaves. Here the nursery line also serves a community as well as the nursery and for years prior to the installation of the new screen the water was put through a large and expensive filter bed. This filter, however, was so unsatisfactory and allowed so much dirt to_ get into the pipes that at times the water was unusable for either purpose.
