  5. 5. Drip History • First commercial drip systems were developed in the early 1960’s • mid 1980’s drippers are incorporated inside the tubing
  6. 6. Grid Layout • Larger Commercial Systems & Turf • Header and footer
  7. 7. Advantage of Drip Irrigation • Efficiency • Drip 92% to 98% Distribution Uniformity • Rainfall 92% to 95% Distribution Uniformity • Soaker Hose 65% to 70% Distribution Uniformity • Sprinklers 55% to 85% Distribution Uniformity – Irrigation Association reports drip irrigation can achieve a 60% water savings over conventional irrigation systems
