Build an Irrigation System That Fits Your Farm
Match your crops, water supply and field layout with the right irrigation components. TREX supplies drip, sprinkler, filtration and control products for growers, distributors and irrigation contractors.
Solve the Problems That Limit Irrigation Performance
A useful specification starts with field conditions. Identify the main constraint before choosing pipe sizes, emitters or sprinklers.
Limited flow or irrigation time
Measure the usable water supply and available operating hours. Divide the farm into zones that can be supplied at the required flow and pressure.
Uneven watering across rows
Account for elevation, pipe friction and lateral length. Match outlet spacing and operating pressure to the crop layout and soil wetting pattern.
Clogging and maintenance
Review water quality and plan accessible filtration, flushing and isolation points. Select controls that the farm team can operate and maintain.
Drip, Sprinkler or Localized Orchard Irrigation?
Choose a method for each crop block. Soil, wind, crop spacing and operating requirements matter more than a single system label.
Drip Tape & Dripline
Deliver water along crop rows with closely spaced outlets. Select tape thickness, emitter spacing and lateral length for the planting pattern and intended service life.
- Useful for repeated rows and targeted root-zone watering.
- Requires suitable filtration and regular flushing.
Sprinkler Irrigation
Apply water over a wider area using overlapping sprinkler patterns. Select nozzles and spacing around operating pressure, wind and soil intake rate.
- Consider crop sensitivity to droplet size and leaf wetting.
- Check pressure at the most demanding sprinkler position.
Drippers & Micro Sprinklers
Position outlets around the active root zone. Adapt emitter count or wetted coverage as trees develop and where planting distances vary.
- Choose discharge and placement from a soil wetting test.
- Verify pressure-compensating products within their rated range.
Different Blocks Can Use Different Methods
A farm may use drip on vegetable rows and sprinklers on a separate field. Give each block its own operating requirements and control arrangement.
Where methods require different pressures or schedules, plan suitable zoning and regulation before sharing a water supply.

| System function | Products to consider | What to confirm |
|---|---|---|
| Filtration | Irrigation filters | Water analysis, flow capacity, filtration grade and cleaning method. |
| Distribution | PP compression fittings and pipe fittings | Pipe dimensions, pressure rating, joint type and connection compatibility. |
| Zone control | Manual and automatic irrigation valves | Zone flow, pressure loss, control method and maintenance access. |
| Water application | Drip tape, micro sprinklers or field sprinklers | Crop spacing, outlet discharge, operating pressure and lateral limits. |
| Monitoring | Pressure gauges and flowmeters | Measurement range, installation requirements and accessible reading points. |
| Optional fertigation | Venturi injectors | Required pressure differential, injection rate, chemical compatibility and backflow protection. |
Keep the Headworks Easy to Inspect
Allow room to clean filters, read instruments and service valves. Establish normal flow and pressure readings at commissioning so changes can be investigated during operation.
Include flushing and air-management provisions appropriate to the layout. Confirm pump duty, protection devices and the final piping arrangement with the project designer.

Turn Field Information into a Product Specification
Describe Your Farm
Provide crop type, field area, row spacing, row length and elevation differences. A sketch with water-source and pipe-route locations is a useful starting point.
Confirm Water and Operation
Share source flow and pressure, water-quality information, irrigation hours and existing equipment. Use these inputs to define zones and component requirements.
Review the Product List
Ask TREX about suitable product models, connection options, quantities and spare parts. Confirm the supply scope, delivery destination and any OEM requirements in the quotation.
Planning a new system or an upgrade? For a new installation, send the proposed field layout. For an upgrade, include existing pipe sizes, equipment labels and pressure or flow measurements.

Which irrigation method is best for my farm?
The choice depends on crop layout, soil, water supply, wind, labor and budget. Drip targets selected root zones, while sprinklers can cover a wider area. Compare the operating requirements of each method for your field.
How much will an agricultural irrigation system cost?
Cost depends on field size, layout, pipe lengths, filtration, outlets and controls. Source distance and available pressure also affect the project. Send a layout and product requirements for a quotation based on defined quantities.
Can I improve an existing system without replacing everything?
Often, selected components can be retained if their condition, capacity and connections suit the revised duty. Share existing specifications and measurements so compatibility can be reviewed before adding new equipment.
Can fertilizer be applied through the irrigation system?
Fertigation can be incorporated with a suitable injection arrangement. Confirm fertilizer compatibility, injection rate, filtration and backflow protection, and follow the equipment instructions and applicable local requirements.
What information should I send for a product recommendation?
Send the crop, field area, row dimensions, water-source flow and pressure, water quality, elevation changes and delivery country. Include drawings or photos of existing equipment when available.
