Self-Cleaning Shallow Water Screen
Anyone who depends on surface water for irrigation will be interested in this self-cleaning screen that’s designed to work in water as shallow as 4 inches.
  “It draws water that’s only 2 inches below the surface, which is usually the cleanest water. There’s nothing else on the market that can pump out of such shallow water and also clean itself at the same time,” says inventor Bob Wietharn.
  The Riverscreen floats on four pontoons and draws water from more than 35 sq. feet of screening area. Water is delivered through a pipe available in 4, 6, 8, 10, or 12 inch diameter with 150 gpm to 4,000 gpm capacity. A screened rotating drum is supported by an aluminum frame that mounts on the pontoons. Flowing water moves past a series of paddles, which force the drum to rotate while a stainless steel spray bar mounted inside the drum cleans the screen.  
  An optional electric drive can be added for use in extreme conditions such as manure lagoons. Also optional is a galvanized lift boom that lets one person quickly swing out and gently lower the Riverscreen to the water surface.
