Microirrigation systems are technically more complex than overhead sprinkler or flood irrigation systems. They require significant maintenance to assure maximum operational efficiency. The intent of this guide is to help micro-irrigation system managers and operators keep their systems running at top efficiency, which will improve crop production and conserve water resources. The performance of a micro-irrigation system may rapidly deteriorate if it is not routinely maintained by:

  • Checking for leaks.
  • Backwashing and cleaning filters.
  • Periodic line flushing.
  • Chlorinating.
  • Acidifying (if necessary).
  • Cleaning or replacing plugged emitters.
  • Evaluating and monitoring system performance.
  • Proper maintenance of a micro-irrigation system will:
  • Extend system life.
  • Improve performance.
  • Minimize shut-down time.
  • Reduce the probability of non-uniform water and fertilizer applications due to emitter plugging.
  • Reduce operating costs.
  • Save water and fertilizer.
  • Improve production.
  • Provide maximum benefits for freeze protection.
