Sprinkler Irrigation System for Farms: Types and Costs

A sprinkler irrigation system sprays water under pressure through pipes and nozzles so it falls on the crop like rain. On farms the main types are center pivots, linear moves, traveling guns, wheel lines and solid set grids. FAO puts the typical field application efficiency of sprinklers at about 75%, against 60% for surface irrigation and 90% for drip.

This guide compares the six farm systems, shows what each one costs using a published USDA NRCS state cost list (Pennsylvania, fiscal year 2026), and gives a calculator so you can test a center pivot on your own acres. It is written for farm owners and managers in the US, Canada, the UK, Europe, Australia and New Zealand.

Sprinkler irrigation system types at a glance

The table sums up the systems used on commercial farms. Costs are from the NRCS Pennsylvania cost list for fiscal year 2026. These are installed-cost estimates that NRCS uses to set conservation payments. They are not dealer quotes, and prices in your area will differ.

How a farm sprinkler system works

Every system has the same four parts. A pump lifts water from a well, canal, pond or river. A main line carries it to the field. Lateral pipes or a moving structure carry it across the field. Nozzles or sprinkler heads break it into drops and spread it over the crop.

The NRCS conservation practice standard for sprinkler systems (code 442) defines them as a “distribution system that applies water by means of nozzles operated under pressure.” The same standard is used for systems that wet the whole field. Drip and micro sprinklers that wet only part of the field fall under a separate microirrigation standard, as the farmdoc daily review of irrigation practice standards explains.

Pressure matters. A Texas A&M AgriLife study of irrigation systems on the High Plains assumed 25 psi for mid-elevation spray pivots and 15 psi for low-elevation spray, LEPA and subsurface drip. Lower pressure means a smaller pump load and lower energy bills, but it also needs nozzles that are set close to the crop.

Water leaves the nozzle and some of it is lost before it reaches the root zone. Small drops drift in the wind. Some water evaporates in hot, dry air. Some lands on leaves and dries there. If the system puts water down faster than the soil can take it in, it runs off or ponds. Good design keeps the application rate below the soil’s intake rate, which is also the advice in FAO’s guide on water quality for leaching salts.

The six farm sprinkler systems compared

Each layout suits a different field, crop and labor situation. Here is what each does well and where it struggles.

1. Center pivot

A center pivot is a line of steel spans on wheeled towers that turns around a fixed pivot point in the field. Each tower has its own small electric motor. One pivot can water a quarter section of about 125 to 130 acres with one operator checking it. Drop hoses can bring the nozzles down close to the crop for low-pressure spray.

Best for: large fields of row crops, alfalfa and potatoes where labor is short. Watch out for: the dry corners of a square field, and wheel ruts on heavy soils.

2. Linear move

A linear move uses the same spans and towers as a pivot but travels in a straight line up and down a field. It is fed from a ditch or a dragged hose. It covers a full rectangle, so no corners are lost. It costs more to run because someone has to move or guide the water supply.

Best for: long, flat rectangular fields and high-value crops. Watch out for: a higher cost per foot than a pivot and more management.

3. Traveling gun

A traveling gun is one large sprinkler on a cart, pulled across the field by a hose that winds onto a reel. It throws water far and handles odd shapes. It needs high pressure, so energy costs are higher, and wind can spoil the pattern.

Best for: pasture, irregular fields and spreading dairy effluent. Watch out for: pump energy and uneven cover on windy days.

4. Wheel line (side roll)

A wheel line is a long aluminum pipe that acts as the axle for large wheels. After each set, a small engine rolls the whole line to the next position. It is cheap to buy but needs someone to move it.

Best for: hay and pasture on flat or gently rolling ground. Watch out for: labor time, and damage if it is moved in high wind.

5. Solid set and permanent set

In a solid set system, pipes and sprinkler heads stay in place for the season or for good. Nothing moves except water. Orchards, vineyards and vegetable growers use these grids because the same heads can water, cool the crop and protect it from frost. Citrus growers in Georgia, for example, use under-tree microsprinklers for freeze protection, as the University of Georgia freeze guide describes.

Best for: orchards, nurseries, vegetables and frost-prone crops. Watch out for: a high cost per acre, because every part of the field needs its own pipe.

6. Hand-move and small portable sets

Hand-move pipe and portable sprinklers on stands are the oldest form of farm sprinkler. They suit small plots, market gardens and pasture patches. Parts are cheap, but the labor is heavy. Many small farms use them as a backup to a larger system.

Best for: small farms, trial plots and short dry spells. Watch out for: long working days and uneven cover if sets are not spaced well.

How efficient is sprinkler irrigation?

Efficiency here means the share of water applied to the field that ends up stored in the root zone where the crop can use it. FAO’s annex on irrigation efficiencies gives indicative field application efficiencies of 60% for surface irrigation, 75% for sprinklers and 90% for drip. FAO also notes that poor discipline in running a system can lower these values.

Pivot nozzle height changes the answer a lot. The Texas A&M AgriLife bulletin B-6113 compared five systems on the High Plains. It assumed 60% efficiency for furrow, 78% for mid-elevation spray (MESA), 88% for low-elevation spray (LESA), 95% for low energy precision application (LEPA) and 97% for subsurface drip. By its index, furrow needed 47% more water than LESA to be as effective, while drip needed 91% of the LESA amount.

The lesson is simple. Moving nozzles closer to the ground and running them at lower pressure can save as much water as changing the whole system. Dropping nozzles on an existing pivot is often the cheaper first step.

Wind and heat also matter. Spray from high nozzles on a hot, windy afternoon loses more water than the same spray at night. Many pivot operators run at night or early in the morning where power tariffs allow it.

What does a farm sprinkler system cost?

Published cost data are scarce because most pivots are sold through dealers on quotes. A useful public reference in the US is the NRCS cost list that each state publishes for conservation programs. The Pennsylvania list for fiscal year 2026 gives these typical costs for practice 442, sprinkler system:

• Center pivot: $9,375.45 base cost per pivot plus $64.04 per linear foot.
• Linear move: $113.54 per foot.
• Swing arm corner unit: $162.76 per linear foot.
• Wheel line: $12.59 per foot.
• Small solid set with above-ground laterals: $3,142.71 per acre.
• Traveling gun: $11,449 (hose under 2 inches), $20,298 (2 to 3 inches) and $36,732 (over 3 inches).
• Variable rate irrigation (VRI) retrofit for a pivot: $39.04 per linear foot.
• Renovation of an existing sprinkler system: $9.15 per foot.

The list also gives higher rates for historically underserved producers. These are cost estimates used to set payments, not quotes. Your price will depend on well depth, power supply, soil, field shape, distance from the dealer and steel prices. A well, pump, power line and main pipe can add a large sum on top of the machine itself.

Running costs come on top. Texas A&M’s bulletin found that energy, labor and repairs differ widely between systems, and that a LEPA pivot had the lowest annual pumping cost in its example. Fuel prices, pumping lift and labor rates changed the ranking, so run the numbers with your own costs.

Cost-share can help. Under EQIP, NRCS can pay part of the cost of an eligible system or upgrade. Rates, caps and rules change each year and by state. Check with your local NRCS office or farm advisor before you order equipment, and get professional advice on loans and tax treatment.

Center pivot cost per acre: test your own numbers

A pivot’s cost only makes sense spread over the acres it waters and the years it lasts. The calculator below takes the NRCS base and per-foot costs as starting values. Change any of them. The yearly saving or gain is the amount you expect the pivot to add per acre each year, from yield, water, labor or energy. The example values are set near break-even on purpose; they are not a forecast.

Why farms are moving from flood to sprinklers

US irrigation has shifted from gravity to pressurized systems for decades. USDA’s Economic Research Service reports that in the western US, 14.7 million acres (37% of irrigated cropland) used pressurized irrigation in 1984. By 2023 it was 29 million acres, or 74%. Pressurized irrigation includes both sprinklers and drip.

The reasons are water and labor. ERS notes that pressurized systems are generally more water-use efficient than gravity systems, because less water is lost to evaporation, deep percolation and runoff. Irrigation matters a lot to farm income: in the 2022 Census of Agriculture, farms with some irrigation produced more than half of the value of US crop sales, while irrigated land was less than 17% of harvested cropland.

Groundwater is the other driver. In parts of the High Plains, well output is falling. As well flow drops, farmers must renozzle pivots to keep them working, as the Texas A&M bulletin explains. A sprinkler that puts the same crop yield on less water buys time on a falling aquifer.

How to choose a sprinkler irrigation system for your farm

Work through these steps before you talk to a dealer. They help you compare quotes on the same basis.

1. Measure your water. Know the flow your well or source can deliver in gallons per minute and how much you are allowed to pump. A system that needs more water than you have will never water evenly.
2. Map the field. Note its shape, slope, obstacles, power lines and buildings. A round pivot on a square field leaves corners dry unless you add a swing arm or a second system.
3. Know your soil. Sandy soils take water fast but hold little. Clay soils hold more but take it in slowly. The application rate must stay below the intake rate.
4. Match the crop. Tall crops like corn need nozzles above or among the canopy. Orchards need under-tree or over-tree heads. Frost-prone crops may need solid set.
5. Count the labor. Wheel lines and hand-move pipe need daily work. Pivots and linear moves need little once set up.
6. Price the energy. Higher pressure means higher pump bills. Ask for the operating pressure and the pump horsepower in every quote.
7. Check water quality. Salty water sprayed on leaves can burn them (see below).
8. Ask about cost-share. Talk to NRCS or your local equivalent before you sign.

Outside the US, the same logic applies. Australian, Canadian and European growers face their own water licensing, power prices and grant rules, so check them locally.

Water quality, maintenance and common mistakes

Water quality affects sprinklers more than drip, because water lands on leaves. FAO’s water quality guide warns that with overhead sprinklers, sodium or chloride above 3 me/l in very dry conditions can lead to leaf absorption, leaf burn and crop damage. Bicarbonate can leave white deposits on fruit and leaves that cut market value, though it is not toxic. Test your water before you choose overhead sprinklers for sensitive crops.

Maintenance keeps uniformity high. Common jobs include:

• Checking nozzles against the sprinkler chart each season, since worn or wrong nozzles change the pattern.
• Cleaning filters and screens, and flushing lines after the off-season.
• Checking pressure at the pivot point and the end of the line.
• Fixing leaks at couplers and drop hoses.
• Looking after tires, gearboxes and tower drives on pivots and linear moves.
• Draining lines before freezing weather in cold climates.

Frequent mistakes include running pressure too high, never checking nozzle wear, watering in strong wind, and putting on more water per pass than the soil can absorb. Each one wastes water and power and can cut yield in the wetter or drier parts of the field.

A simple catch-can test shows how even your system is. Set rows of identical cans under the sprinkler, run it for a set time and measure the depth in each can. Big differences between cans mean worn nozzles, wrong pressure or poor spacing.

Scheduling, sensors and variable rate irrigation

The best machine still wastes water if it runs at the wrong time. Scheduling means deciding when to water and how much, based on crop water use, rain and soil moisture. Tools range from a simple checkbook of rainfall and estimated crop use to soil moisture probes, weather stations and canopy temperature sensors.

Research on pivots shows what sensors can do. A Nebraska CropWatch article on sensors mounted on a pivot describes automated scheduling from crop water stress readings, and notes that if every field cut seasonal irrigation by one inch it would help water resources a lot. In a USDA-ARS study in Frontiers in Plant Science, deficit irrigation at 75% of the full amount kept cotton yield level while using at least 20% less water in 2021 and at least 16% less in 2022 than full irrigation. The automated sensor-feedback system gave results similar to manual scheduling with less work.

Variable rate irrigation (VRI) lets a pivot apply different amounts in different zones, by speeding up or slowing down the machine or by switching nozzle banks. A University of Nebraska study of maize and soybean in west-central Nebraska tested VRI under full and deficit irrigation. In 2018 VRI cut prescribed irrigation compared with uniform watering, but yields did not differ between treatments in either year.

Satellite crop maps are another input. They show which parts of a pivot circle are greener or more stressed than others, which helps you spot a blocked nozzle, a leak or a dry zone. Farmonaut gives satellite vegetation and water stress maps for each field you draw, through the season, on web, Android and iOS. For more on sensors and controllers, see our guide to the advantages of smart irrigation.

Water sprinklers for small farms and gardens

Not every farm needs a pivot. Small vegetable farms, market gardens and hobby farms often use a mix of simpler tools:

• Impact sprinklers on risers: cheap, sturdy heads whose throw depends on pressure and nozzle size.
• Rotor and spray heads on hand-move pipe: good for strips of vegetables or small hay fields.
• Hose-end and tripod sprinklers: fine for small plots, but slow and uneven over large areas.
• Micro sprinklers: low-flow heads for orchards, nurseries and greenhouses that wet part of the ground.
• Small traveling sprinklers: self-moving carts that follow a hose; handy for pasture and lawns around a farmstead.

For a small farm, start with the water you have, then size the sprinklers to it. A head that needs more flow than your pump can give will throw a short, patchy pattern. Overlap spray circles by about half so each spot gets water from more than one head. Water early in the morning to cut evaporation and leaf disease.

Many small growers mix methods: drip for vegetables and fruit, sprinklers for pasture and germination. That keeps costs down and puts each method where it works best.

Sprinklers and the environment

Sprinklers can cut water use when they replace poorly run flood irrigation, but there is a catch. Water saved on one field is not always saved for the basin. If the farmer uses saved water to irrigate more land, total water use may stay the same. Extension economists and policy studies, including the farmdoc daily review, discuss this when judging conservation practices.

Sprinklers also reduce soil erosion compared with furrow irrigation on sloping land, because water does not flow over the surface. They can deliver fertilizer through the water (fertigation), which lets you split nitrogen into smaller doses. Always follow product labels and local rules for chemigation, including backflow prevention devices.

On energy, a pressurized system uses more pump power than gravity flow. Lower-pressure nozzles, efficient pumps and night running reduce this cost and its carbon footprint.

FAQ

What is a sprinkler irrigation system?

It is a way of watering crops by pumping water through pipes to nozzles that spray it over the field like rain. Farm types include center pivots, linear moves, traveling guns, wheel lines and solid set systems.

How much water does sprinkler irrigation save?

FAO gives indicative field application efficiencies of 75% for sprinklers and 60% for surface irrigation. Low-pressure pivots with nozzles near the crop can reach higher values; a Texas A&M study assumed 88% for LESA and 95% for LEPA.

How much does a center pivot cost?

The NRCS Pennsylvania FY2026 cost list uses $9,375 per pivot plus $64.04 per foot. For a 1,300-foot pivot that is about $92,600 before the well, pump, power and main line. Dealer quotes in your area will differ.

Which is better, sprinkler or drip irrigation?

Drip is more efficient (about 90% in FAO’s figures) and keeps leaves dry, but it costs more per acre for field crops. Sprinklers suit large fields, close-spaced crops, pasture and frost protection. Many farms use both.

Can I get help paying for a sprinkler system?

In the US, NRCS programs such as EQIP can share the cost of eligible systems and upgrades. Rules and rates change each year, so check with your local NRCS office and get professional advice before you buy.
