• Thickness is PN6 to PN25
• Positioning.  Sub-surface pipes.
• Operation. PVC irrigation pipes are main or sub-main lines.
• Origin. From a reservoir, a water pump borehole, main line, or sub main line

3. Delivery pipes

Types of Pipes Used in Irrigation; how to select irrigation pipes

1. Irrigation method

Is it drip, overhead or rain hose irrigation?

2. Crop type

A vegetable crop will have pre-perforated drip pipes as laterals. A fruit tree crop will have a 16mm HDPE pipe as the lateral

3. Crop stage of growth

A crop in the nursery will have an overhead or rain hose kit irrigation system. The one in the field will have any

4. Crop production method

A greenhouse crop will be HDPE or PVC and drip pipes based only

5. Land ownership type

A grower who is the farm owner or on a long term land lease will invest in sub-surface pipes. A short lease grower will prefer surface pipes

6. Water pressure

A grower with low gravity flow will have the PN6 pipes. One with high pressure flow will have thicker pipes

7. Irrigation area

Small farms will have low diameter pipes, large farms have large diameter pipes

8. Budget

A proper budget provides the right pipes
