| Step 1. |
Evaluate area to be irrigated including plant material, soil type, topography, slope and water source. Water source information includes water pressure, quantity available and water quality. |
| Step 2. |
Based on soil type, select the optimum
DURA-FLOTM
PC dripperline from Chart 1 on page 5. |
| Step 3. |
Prepare a basic layout design based on the options shown on pages 2 and 3. |
| Step 4. |
Check the maximum recommended length of run and system operating pressure requirements from Chart 2 on page 7. |
| Step 5. |
Determine width of area to be irrigated and then calculate actual spacings between dripperlines as in Section 6 on page 6. Also refer to Section 9 on pages 11 and 12 for steep slopes if necessary. |
| Step 6. |
Calculate system or zone flow rates as per Section 14 on pages 18 and 19. |
| Step 7. |
Size headers and pipes based on system or zone flow rates (do not exceed 5 feet/second velocity in headers). |
| Step 8. |
Position automatic flush valves and air vacuum relief valves based on criteria given in Section 8 on pages 9 and 10. |
| Step 9. |
Select appropriate filter based on system or zone flow rate and emitter minimum filtration requirement. See Chart 8 on page 21. |
| Step 10. |
Select correct pressure regulator based on system or zone flow rates and optimum system pressure requirement. |
