Irrigation system design sounds straightforward until you are the one making the decisions. Do you go with a center pivot or drip? How do you match your system to your well? What nozzle package makes sense for your soil type? Should you retrofit your existing infrastructure or start fresh?
In West Texas, these decisions carry extra weight because the conditions here are unforgiving. You are dealing with a depleting aquifer, high evaporation rates, sandy soils with limited water-holding capacity, and enough wind to meaningfully affect how water lands on the ground. Get the design right and your system performs efficiently for decades. Get it wrong and you spend years chasing problems that were baked in from the start.
This guide covers the core principles of irrigation system design for West Texas farms, and what a professional system design engagement actually delivers.

Start with Your Water Source, Not Your Equipment
This is the most important principle in irrigation system design and the one most commonly ignored when farmers start shopping for equipment before they understand what their water supply can actually support.
Your irrigation system is only as good as the well feeding it. Before you select any equipment, you need to answer:
- • What is your well's sustained yield? Not the pump rate, but the rate the aquifer can deliver over a full irrigation season without pulling the water level below your pump intake.
- • How has your water level changed over the past 10 years? Declining water tables change what is economically feasible in system design.
- • What is your water quality? In parts of West Texas and the Texas Panhandle, groundwater quality affects nozzle selection, filtration requirements, and drip emitter longevity.
- • What legal restrictions apply? Water rights and groundwater conservation district regulations vary across the region and affect how much you can legally pump.

Match Your System Type to Your Operation
No single irrigation technology is right for every West Texas farm. The main options and when they make sense:
Center Pivot Systems
Center pivots are the dominant irrigation technology across the Texas Panhandle for good reason. They cover large acreage efficiently, they can be automated and monitored remotely, and modern pivot systems with LEPA or drag-hose nozzles achieve high application efficiency even in West Texas conditions.
Center pivots work best for:
- • Fields of 100+ acres with reasonably regular geometry
- • Crops like cotton, corn, grain sorghum, and wheat that cover the ground and can tolerate pivot traffic
- • Operations with adequate well yields to support a full-circle system
Drip Irrigation
Drip systems apply water directly to the root zone, virtually eliminating evaporation losses at the point of application. In West Texas heat and wind, that is a significant advantage.
Drip irrigation works best for:
- • High-value crops where the economics justify higher installation costs
- • Row crops like cotton where subsurface drip delivers water precisely to the root zone
- • Fields with sandy soils that benefit from frequent, small applications
- • Operations with limited well yields where pivot coverage is not feasible
Combination Approaches
Some West Texas operations benefit from using center pivots for large, regular fields and drip systems for smaller or irregular parcels, or for high-value crops within a larger operation. Pro-Tech Irrigation evaluates your full farm layout before recommending a single technology or a combination.

Nozzle Selection: The Decision That Affects Every Irrigation Event
In West Texas, overhead sprinkler nozzles waste water. Full stop. When you apply water through an overhead sprinkler in summer conditions, evaporation and wind drift pull a meaningful percentage of that water out of the equation before it reaches the crop.
The alternative is applying water closer to the ground:
LEPA (Low Energy Precision Application): Water applied within 18 inches of the soil surface through drag hoses or bubbler devices. Evaporation losses are minimal. Application efficiency is significantly higher than overhead systems. Pressure requirements are lower, which reduces pumping costs.
Drag Hose Systems: A practical midpoint between overhead sprinklers and true LEPA. Water applies within 24-36 inches of the surface, reducing drift and evaporation while being more tolerant of residue conditions than pure LEPA.
Nozzle selection interacts with your soil type and field management. LEPA requires adequate furrow or residue management to prevent runoff on any slope. On flat, well-managed fields in the Texas Panhandle, it is consistently the right call for cotton and other row crops.

Key Design Decisions and the Mistakes Farmers Make
Mistake 1: Designing for Peak Crop Demand Without Accounting for Well Capacity
If your system is designed to apply 0.35 inches per day at peak demand but your well cannot sustain that rate for more than a few hours, you have a mismatch. The system sits idle waiting for the well to recover, and your crops stress during the gap.
The fix is designing your system to match the well's sustained delivery rate, then compensating through soil moisture management and scheduling rather than expecting the system to always run at maximum capacity.
Mistake 2: Ignoring Soil Spatial Variability
Your fields are not uniform. Soil texture, organic matter, and water-holding capacity vary across even a single quarter section. A system designed as if the whole field is the same will over-water some zones and under-water others.
Variable rate irrigation (VRI) technology addresses this by adjusting application rates by zone as the pivot rotates. It adds cost, but on highly variable fields it recovers that cost through better yield and water savings.
Mistake 3: Undersizing Infrastructure for Future Needs
If you plan to add acreage, upgrade your pump, or convert additional fields to irrigation in the next 10 years, design your current system with that capacity in mind. Upgrading distribution lines, adding pump infrastructure, and rerouting water supply lines years later costs more than doing it right initially.
Mistake 4: Skipping the Written Design Document
A verbal recommendation from a salesperson is not a system design. A legitimate irrigation system design includes written specifications for every component: pipe sizing, pressure calculations, nozzle selection, pump specifications, and a full field layout. You need this documentation to get accurate bids, to troubleshoot problems in year five, and to pass along to whoever manages the operation in the future.

Frequently Asked Questions: Irrigation System Design in West Texas
Q: How much does a professional irrigation system design cost? A: Design costs vary based on the scope and complexity of the engagement. A detailed farm analysis and written system design for a single quarter-section typically runs $2,000 to $5,000. For operations with multiple fields or more complex water supply situations, the scope expands accordingly. Contact Pro-Tech Irrigation for a specific scope and cost estimate.
Q: How long does the design process take before I can order equipment? A: A thorough design engagement for a West Texas farm typically takes two to four weeks from initial site visit to final written design. Complex operations with multiple fields or significant water supply challenges take longer. Rushing the design to save time is a false economy.
Q: Can Pro-Tech Irrigation design a system that works with my existing well infrastructure? A: Yes. We routinely work with existing wells, pumps, and distribution infrastructure. The design process starts with an honest assessment of what your current infrastructure can support and builds from there.
Q: Is drip irrigation realistic for cotton in West Texas? A: Subsurface drip for cotton (SDI) has been used successfully across the Texas High Plains for two decades. It delivers water directly to the root zone, eliminates runoff and evaporation losses, and allows efficient fertigation. It requires careful management and higher upfront investment, but on the right operation it delivers strong returns on water and yield.
