Drip History
• First commercial drip systems were developed in the early 1960’s
• mid 1980’s drippers are incorporated inside the tubing
Grid Layout
• Larger Commercial Systems & Turf
• Header and footer
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
