Filtration, Treatment, and Maintenance Considerations for Micro-Irrigation Systems

442-757 (BSE-222P) Micro-irrigation systems can deliver water and nutrient in precise amounts and at controlled frequencies directly to the plant’s root zone. With micro-irrigation systems an extensive network of pipe is used to distribute water to emitters that discharge it in droplets, small streams, or through mini-sprayers. The major cause of failure in micro-irrigation systems is emitter plugging. Emitter plugging can severely degrade irrigation system performance and application uniformity. The goal of this document is to provide information on common water quality problems that can lead to emitter clogging, and how these problems can be addressed through water treatment and system maintenance. This should help producers identify, prevent, diagnose, and address clogging problems in their micro-irrigation systems. 8.5 x 11, DS, 20#, BW, color pages 4 & 5, single staple upper left
