Inexpensive Sand Filters for Drip Irrigation Systems

Abstract

Solid particles in water such as sand, silt, clay, or organic debris can clog drip irrigation systems. Filters that remove these particles from the water are necessary, but expensive, for small-scale or part-time farmers. A falter that is functionally similar to commercial units can be built from a steel barrel and common plumbing supplies for about $100. Components and instructions to build such a falter are presented here.
