1. Basic Landscape Irrigation Systems

3. Controller and Valves
Valve “manifold”

4. Drip Irrigation

5. Plan for Adequate Spray Coverage
Odd shaped areas can be effectively covered using adjustable pattern nozzles that adjust from 0 to 360 degrees.
Head-to-head coverage

6. Use Watering Zones Water supply capacity = 17 GPM (gallons per minute)
Landscape requires 28 pop-up sprinkler heads
Each head delivers 1.5 GPM
28 x 1.5 = 42 GPM (total water volume needed)
Break landscape into manageable sections or “zones”
→ 42 ÷ 17 = 2.47
→ Need 2.47 or 3.00 water zones for proper coverage
