Summer Irrigation Efficiency in West Texas: 5 Things to Check Before Peak Heat

West Texas summers do not forgive slow decisions. By the time daily highs push past 100°F and evaporation rates spike, a poorly tuned irrigation system is not just wasting water. It is cutting directly into yield and your water budget.

Here is what farmers should check right now before peak heat locks in.

1. Pressure Regulators Deserve an Inspection Now

Pressure too high blows mist past the root zone. Pressure too low means uneven distribution and dry patches. In West Texas, wind compounds both problems. High-pressure mist drifts before it hits the ground, and low-pressure patterns fall short on hot, windy afternoons.

Walk your zones and confirm regulators are functioning within spec. If a regulator is more than five to seven years old, it is worth bench-testing or replacing before peak season, not after the first dry-out.

2. Nozzle Wear Is Costing You Water You Cannot See

Nozzles degrade faster than most operations expect, especially on pivots running high-iron water or heavy sediment loads. A worn nozzle delivering 10% more water than spec does not sound serious until you multiply it across 300 heads on an 800-acre pivot.

Pull a sample from each field and flow-test them this week. Clogged emitters on drip lines deserve a separate inspection. They fail silently and only show up as crop stress after the damage is done.

3. Run Times Are Probably Still Set for Spring

In June and July, evapotranspiration in West Texas regularly hits 0.30 to 0.35 inches per day. If your pivot schedule is based on spring conditions or last year's baseline, you are either under-irrigating during the hottest windows or over-watering at night when plants cannot fully use it.

Pull your current ET data and match it against your actual application rates. Adjust pivot speed and timing accordingly. Running during early morning or late evening hours reduces surface evaporation loss and meaningfully improves your effective application rate.

4. Check Pump Performance Weekly Through Peak Season

Pump efficiency drops gradually and farmers usually do not notice until fuel costs spike or flow tests come up short. A pump running at 85% efficiency means you are paying to move 15% more water than you are applying, or applying 15% less than you think.

Pull flow rate and pressure readings weekly through peak heat. Compare against your baseline. Consistent degradation usually points to impeller wear or a suction-side issue. Both are manageable catches if you get to them before a mid-season breakdown.

5. Seal Known Leaks Before the Season Peaks

A 5 GPM leak running 20 hours a day loses about 600 gallons daily, every day of the growing season. In a water-scarce region like West Texas, that is not just a cost problem. It is an allocation problem that compounds over time.

Walk your lines now. Focus on joints, valve boxes, and prior repair points. Fix before peak demand hits, not during it.

When It Is Time to Bring In Support

If your system has not had a full performance evaluation this season, summer is not the time to learn about a major problem mid-crop. Pro-Tech Irrigation provides irrigation system design, water management consulting, and farm efficiency analysis across the Lubbock area and West Texas.

Whether you are fine-tuning an existing pivot or evaluating a drip conversion for next season, early summer is the right window to get ahead of problems before peak heat forces the issue.
