Abstract
A water-powered, self-cleaning rotary strainer for use in drawing water from a running stream. A perforated drum is rotatably mounted on a frame. Drum rotation is done by using moving water. A float is mounted on the frame to support the drum in a partially submerged condition. Water is withdrawn from the interior of the drum through a conduit as the drum rotates and debris is passed around the drum.
