Spring Irrigation System Startup in Lubbock, TX: A Guide for Farmers and Ranchers

# Spring Irrigation System Startup in Lubbock, TX: A Guide for Farmers and Ranchers

The 2026 growing season is approaching, and for farmers and ranchers across the Lubbock, TX area, that means it is time to bring irrigation systems back online. A proper spring startup is not just flipping a switch. Center pivots, subsurface drip systems, and pump stations that sat idle through the West Texas winter need a systematic inspection, testing, and commissioning process before they are ready to deliver water to your crops.

Pro-Tech Irrigation has been servicing agricultural and commercial irrigation systems throughout the Lubbock region and the Texas South Plains for years. This guide covers the complete spring startup process, what to watch for, what it costs, and how to avoid the problems that cost growers time and money during the critical early weeks of the season.

Why Spring Startup Matters in West Texas

Lubbock County and the surrounding South Plains sit on top of the Ogallala Aquifer, one of the most heavily utilized groundwater sources in American agriculture. Water is not getting cheaper or more abundant. Every gallon wasted through leaking gaskets, misaligned sprinkler heads, or an improperly calibrated VFD is money lost and aquifer drawn down unnecessarily.

A disciplined spring startup process catches problems while they are still cheap to fix. A cracked fitting found during inspection costs $20 to replace. That same fitting left undetected sends water and pressure where it does not belong, potentially damaging nozzles, washing out soil, or causing a pivot to bog down in a wet spot during the first pass of the season.

The Spring Startup Checklist

1. Pump Station Inspection

Your pump is the heart of the system. Before you run it, inspect these components:

• • Motor and drive shaft: Check for corrosion, worn bearings, and belt condition. Listen for unusual noise during a brief test run.
• • VFD (Variable Frequency Drive): If your system has a VFD, check the display for fault codes. Clear any stored faults and verify that programmed settings match your operating parameters for the upcoming season.
• • Intake screen and check valve: Remove and clean the intake screen. A clogged screen reduces flow rate and puts unnecessary stress on the pump. Inspect the check valve for proper seating.
• • Pressure gauge calibration: Compare your gauge reading to a known-good reference gauge. Inaccurate pressure readings lead to incorrect system adjustments.
• • Electrical connections: Tighten all terminals. West Texas temperature swings cause thermal cycling that loosens connections over time. A loose connection that arcs can damage controls or start a fire.

2. Pipeline and Mainline Inspection

Walk your buried mainline route and look for signs of problems:

• • Wet spots or sink holes that indicate a broken pipe or joint failure below grade
• • Riser pipes and valves: Open and close every valve manually. Seized valves need to be freed or replaced before the season starts.
• • Air relief valves: Make sure they are operational. Air trapped in your mainline during initial fill can create water hammer that damages pipes and fittings.

3. Center Pivot Inspection

Center pivots cover a lot of ground and have hundreds of individual components. A systematic walk of the entire machine is essential.

• • Span alignment: Sight down the pivot from the pivot point. Spans should be straight and level. Sagging or offset spans indicate structural fatigue or damaged truss rods.
• • Tire condition and inflation: Check all tires for dry rot, sidewall cracks, and proper inflation. Low tires cause tracking problems and uneven water application.
• • Sprinkler heads and nozzles: Inspect every head. Replace any that are cracked, clogged, or missing. Verify that nozzle sizes match your system design. Mismatched nozzles throw off your application rate and uniformity.
• • Drop hoses and regulators: Check for UV damage, leaks at connections, and proper regulator operation. Pressure regulators wear out and need replacement every 5-7 years.
• • Span drive motors and gearboxes: Check gearbox oil levels and look for leaks at seals. Low oil in a gearbox will destroy the gears within a few hours of operation.
• • Control panel: Test the panel at the pivot point. Run the machine in a short forward and reverse cycle. Check end gun operation, safety shutdowns, and any GPS guidance or telemetry systems.

4. Subsurface Drip Irrigation (SDI) Startup

SDI systems require a different startup approach:

• • Flush all laterals: Open flush valves at the end of each lateral and run the system until water runs clean. Sand and sediment accumulate during the off-season and will clog emitters if not flushed.
• • Check filtration: Clean or replace filter elements. Sand media filters need the media bed inspected for channeling. Disk filters need disks cleaned and reassembled.
• • Pressure test: Run the system at operating pressure and check for leaks at all connections, especially at header manifolds and lateral connections.
• • Flow rate verification: Compare measured flow rates to design specifications. A significant drop in flow rate indicates clogged emitters that need chemical treatment.

Common Spring Startup Problems in the Lubbock Area

Sand in the System

The Ogallala Aquifer produces varying amounts of sand depending on well depth and location. Wells in Hockley County, Lamb County, and parts of Lubbock County are particularly prone to sand production. If your well is producing sand, you need a sand separator or centrifugal filter installed upstream of your pump to protect downstream equipment.

Freeze Damage

West Texas winters regularly drop below freezing, and the 2025-2026 winter brought several hard freezes to the South Plains. Components that are most vulnerable to freeze damage include:

• • Pressure gauges
• • Backflow preventers
• • Above-ground pipe sections and risers
• • Chemical injection equipment
• • Pivot drain valves that failed to drain completely

Electrical Issues

Rodents nesting in control panels and junction boxes during winter is a persistent problem across the Lubbock area. Mouse damage to wiring causes intermittent faults that are difficult to diagnose. During startup, open every panel and junction box and inspect wiring for chew marks, nesting material, and insulation damage.

Worn Sprinkler Packages

Sprinkler nozzles wear out gradually, and the performance loss is not obvious until you compare actual application rates to design specs. If your sprinkler package is more than 7 years old and you have not replaced nozzles, you are likely over-applying water in some areas and under-applying in others. A nozzle replacement during spring startup is one of the highest-return investments you can make in water efficiency.

Spring Startup Costs

| Service | Typical Cost | |---|---| | Full pivot inspection and startup | $500 - $1,200 | | Pump station inspection and commissioning | $300 - $800 | | SDI system flush and pressure test | $400 - $1,000 | | Nozzle package replacement (full pivot) | $1,500 - $4,000 | | VFD programming and calibration | $200 - $500 | | Emergency repair (during season) | $150 - $300/hour + parts |

Investing $800 to $2,000 in a thorough spring startup is inexpensive compared to the cost of a failed system during peak water demand. A pivot that goes down for three days in July while your cotton is setting bolls can cost thousands in yield loss.

Frequently Asked Questions

When should I start my irrigation system in Lubbock, TX?

Most Lubbock area growers begin startup in mid-March to early April, depending on crop type and planting schedule. Cotton operations typically need systems operational by late April. Earlier crops like winter wheat may need irrigation as early as March. Schedule your startup inspection at least 2-3 weeks before you need to run water.

How often should center pivot nozzles be replaced?

Nozzle performance degrades over time due to sand abrasion and UV exposure. Plan to inspect nozzles annually and replace the full package every 5-7 years. If your water source has high sand content, replacement may be needed every 3-4 years. The cost of new nozzles is far less than the cost of wasted water and uneven application.

Can Pro-Tech Irrigation service systems outside of Lubbock County?

Yes. Pro-Tech Irrigation services agricultural and commercial irrigation systems across the Texas South Plains, including Hockley County, Lamb County, Terry County, Lynn County, and Crosby County. Call (214) 264-4793 to discuss your location and service needs.

What is the most common cause of irrigation system failure during the growing season?

Electrical problems are the most common cause of in-season failures in the Lubbock area. Loose connections, rodent damage to wiring, and lightning strikes account for the majority of emergency service calls. A thorough electrical inspection during spring startup prevents most of these failures.
