An irrigation system is any network of pipes, emitters or sprinklers that delivers water to crops, turf or landscaping instead of relying on rainfall alone. The three main categories are in-ground (buried 2–8 inches, feeding fixed sprinkler heads or drip lines), above-ground (visible pipe, hose, or pivot equipment laid on the surface), and underground drip (buried 8–18 inches, delivering water straight to the root zone). USDA’s most recent national survey counted 212,714 US farms irrigating 53.1 million acres in 2023 — so if you are searching for “irrigation system near me,” you are one of a very large group deciding between these three approaches, and the right answer depends on what you’re growing, your soil, and your water source.

Quick Answer: Which System Fits Your Situation

If you’re comparing options before calling a local installer, here’s the short version. An above-ground drip irrigation system is the cheapest and fastest to install — no trenching, easy to move between seasons — but loses more water to evaporation and wind drift. An in-ground irrigation system buries pipe just below the surface for permanent sprinkler zones on lawns, orchards and landscaping. An underground irrigation system for farms, typically subsurface drip, buries emitter tubing 8–18 inches deep at the root zone and is the most water-efficient of the three, which is why it dominates in permanent crops and drought-prone regions. If you’re building it yourself, a basic DIY irrigation system or homemade irrigation system using surface drip tape and a timer can be assembled from hardware-store parts in an afternoon — see the DIY section below for what that actually requires.

US Irrigation By The Numbers

USDA’s National Agricultural Statistics Service (NASS) runs the Irrigation and Water Management Survey as a follow-on to the Census of Agriculture. The most recent full release, published October 31, 2024 and covering the 2023 crop year, found 212,714 US farms irrigating 53.1 million acres, applying a combined 81 million acre-feet of water — an average of 1.5 acre-feet per acre. That’s down from 55.9 million acres irrigated and 83.4 million acre-feet applied in the 2018 survey, a modest contraction in irrigated footprint even as the pressure to use each acre-foot more efficiently has grown. Energy to pump that water cost US farms $3.3 billion in 2023. Full detail is in USDA NASS’s 2023 Irrigation and Water Management Survey release, with the 2018 comparison figures in the 2022 Census of Agriculture irrigation highlights.

The next release in this series is expected from USDA NASS around October 2025, covering 2024 data — check the same NASS Newsroom link above for the updated acreage, water-applied, and energy-cost figures once it posts, since these numbers shift with commodity prices, drought conditions and well-permitting activity year to year.

Types of Irrigation Systems: In-Ground, Above-Ground & Underground

Each of the three main categories trades installation cost against water efficiency and root-zone precision. Below is what distinguishes them in practice.

In-Ground Irrigation System: Precision Below the Surface

An in-ground irrigation system is a network of pipes, valves and emitters installed 2–8 inches beneath the soil surface, close enough to root zones for targeted delivery without the visible clutter of surface hose and sprinkler equipment.

• Application: Orchards, vineyards, tree plantations, and increasingly residential and commercial turf where a permanent, zoned system is worth the upfront trenching cost.
• Technologies: Soil-moisture sensors, timers, and weather-integrated controllers schedule watering by zone rather than a single blanket cycle.
• Benefits: Less evaporation than surface sprinklers, supports root health, reduces foliar disease risk by not wetting leaves, and pairs with fertigation for combined water-and-nutrient delivery.
• Structure: Built in modular zones, so a system can be sized to an odd-shaped lot or expanded field by field.

Above-Ground Drip Irrigation System: Flexibility for Large Areas

An above-ground drip irrigation system runs tubing and emitters along the soil surface rather than burying them — the drip-tape equivalent of the visible pipe, sprinkler and pivot equipment used in row-crop and pasture irrigation.

• Application: Extensive field-crop and pasture operations, community gardens, and any site where underground installation is impractical, too costly, or would disturb existing root systems.
• Technologies: Portable controllers, seasonal timer programs, and rain sensors; generally less automated than buried in-ground or underground networks, though upgrade kits exist.
• Benefits: Cheapest to install, no trenching, easy to repair or relocate between seasons — ideal for rotational grazing or annual vegetable beds.
• Limitations: Higher evaporation and wind-drift losses than buried systems, and less precise root-zone targeting.

A California Department of Food and Agriculture field trial on commercial sweet corn found drip irrigation cut water use by 37 percent compared with furrow irrigation — a comparison that illustrates why even a surface drip setup outperforms flood or furrow methods, even without burying anything. Detail is in the CDFA commercial drip irrigation efficiency study.

Underground Irrigation System & Underground Drip Irrigation System for Farms

An underground irrigation system for farms — most commonly subsurface drip irrigation (SDI) — buries tubing and emitters 8–18 inches deep, directly at the root zone, rather than at the surface or in shallow in-ground trenches.

• Application: Permanent and semi-permanent crops (vineyards, orchards, tree plantations) and large-scale landscaping where root-zone moisture control matters most; also used in mining-land reclamation to establish erosion-controlling vegetation.
• Technologies: Moisture sensors and automated controls that can integrate with weather data and satellite-based field monitoring — see Farmonaut’s API for one example of that integration path.
• Benefits: Minimizes evaporation and surface runoff since water never reaches open air, reduces weed germination (the surface stays drier), and avoids the foliar wetting that spreads fungal disease.

USDA’s Census of Agriculture recorded a 71 percent increase in drip irrigation system adoption between 2007 and 2017 — the clearest national signal of how fast subsurface and surface drip have displaced flood and older sprinkler methods, per the USDA Census of Agriculture Farm and Ranch Irrigation Survey guide. The next Census of Agriculture is due in 2027; check that same page for the updated adoption share by system type once it publishes.

Underground drip irrigation system conversions have gained ground fastest in regions facing unreliable rainfall or aquifer decline, where every acre-foot saved delays a well’s depletion timeline.

Groundwater Irrigation: Wells vs Surface Water

“Groundwater irrigation” refers to pumping from wells rather than drawing from a river, canal or reservoir. Whichever of the three system types you choose above ground, the water still has to come from somewhere below it or beside it. USDA’s 2023 survey found 54 percent of US irrigation water came from groundwater wells rather than surface sources — meaning a slight majority of American irrigated acres now depend on aquifer withdrawal rather than river or reservoir diversion. That split matters for system choice: groundwater-fed systems typically run at higher, steadier pressure from a well pump, which suits pressurized drip and micro-sprinkler networks well, while gravity-fed surface-water systems more often pair with furrow or flood methods unless a booster pump is added. Pumping that groundwater is also where most of the $3.3 billion in national irrigation energy costs for 2023 gets spent, since well pumps run on electricity or diesel that surface-water gravity systems don’t need. Source: the same USDA NASS 2023 Irrigation and Water Management Survey.

A groundwater irrigation system built around a private well needs its own permitting check with your state water resources agency or, for the High Plains and Central Valley regions, coordination with the relevant groundwater management district — well yield and drawdown limits vary by aquifer and are not part of USDA’s national survey, so confirm locally before sizing a pump.

DIY & Homemade Irrigation Systems

A DIY irrigation system or homemade irrigation system is almost always a surface drip or soaker-hose setup: a garden hose or drip-tape line run from an outdoor spigot through a simple timer, with punched-in emitters or a soaker hose laid along planting rows. The core parts are a backflow preventer, a pressure regulator (drip emitters are rated for low pressure, typically far below household line pressure), a filter to keep emitters from clogging, the tubing or tape itself, and a battery-powered timer. None of that requires trenching or a professional install, which is why it’s the entry point most home gardeners and small-plot growers start with before considering a buried in-ground or underground system. The tradeoff is the same one above-ground systems carry at farm scale: more evaporation exposure and a shorter component lifespan than buried tubing, since surface drip tape sits in direct sun and gets nicked by foot traffic or mowing equipment.

Irrigation System Comparison Table

A note on cost: the research behind this article did not turn up an official USDA per-acre installation price study covering all three system types, and industry quotes vary too widely by region, crop, and site conditions to publish as a single figure without risking a made-up number. If you need an installation estimate, the reliable path is to request quotes from at least two local irrigation contractors for your specific acreage and soil type — see the expert-finding section below.

Ancient Irrigation Systems: Where This Started

Every modern system above descends from the same basic problem ancient farmers solved without pumps, sensors or plastic tubing: getting water from a source to a root zone with minimal loss. Ancient irrigation relied on gravity-fed canals, qanats (sloped underground tunnels that carried groundwater from higher elevations to fields without surface evaporation), and terracing to slow runoff on sloped land. The qanat is worth noting specifically because it’s the direct conceptual ancestor of today’s underground irrigation system: both move water below the surface, out of the sun, to avoid evaporation loss — the qanat did it with gravity and tunnel depth, subsurface drip does it with buried pressurized tubing. Terracing likewise anticipated the erosion-control role that in-ground sprinkler systems and grass irrigation systems now play on modern slopes and embankments. The throughline is durable even though the hardware isn’t: minimizing the distance water travels through open air is still the single biggest lever on irrigation efficiency, whether the engineering is 2,000 years old or installed last week.

Finding Irrigation System Experts Near You

If you’re searching for “irrigation system experts” or “irrigation system near me” because you want an installer rather than a DIY project, a few screening questions separate a qualified contractor from a general landscaper who also installs sprinklers:

• Ask for system-specific experience. Subsurface drip design (emitter spacing, filtration, flush-line placement) is a different skill set from above-ground pivot or in-ground sprinkler-zone layout — ask for references on the specific system type you want.
• Ask how they size the system to your water source. A contractor who doesn’t ask whether you’re on a well or surface water, or what your pump’s gallons-per-minute output is, before quoting a design hasn’t done the basic sizing work.
• Ask about local permitting. Well-based groundwater irrigation systems in many Western states require a water-rights permit or registration with the state engineer’s office or a groundwater management district — a qualified local expert will know your jurisdiction’s requirement without being asked twice.
• Ask for a maintenance plan, not just an install quote. In-ground and underground systems have a low maintenance frequency day-to-day but a real one: winterization in freeze-prone regions, periodic emitter flushing to prevent clogging, and zone-valve inspection.

Independent of who installs it, satellite monitoring can validate that a system is actually working as designed after installation — see the Farmonaut section below for how that check works without a site visit.

Enter your irrigated acreage, current system type, and local water cost to see the estimated annual water and cost difference from switching to a more efficient system.

Assumptions: the 37% reduction for above-ground-to-underground is drawn directly from the CDFA commercial sweet-corn drip-vs-furrow trial; the 20% figures for other transitions are placeholder estimates for illustration, not published USDA figures, since no single study scores all three system types against each other. Excludes installation cost, financing, and crop-specific yield effects — treat the output as a starting estimate to refine with a local contractor’s quote, not a guaranteed savings figure.

Technology & Monitoring Trends

Across all three system types, the same three technology layers are converging: field sensors, automated controls, and remote monitoring.

Precision Irrigation: IoT, AI, and Advanced Sensors

• IoT sensors for soil moisture, salinity and temperature feed minute-by-minute data that a controller uses to adjust timing and volume automatically.
• AI-based advisory — Farmonaut’s Jeevn AI is one example — turns weather and field data into irrigation recommendations for growers and land managers.
• Automated zone control lets each section of a field or landscape run its own schedule instead of one blanket cycle for the whole property.

Get crop and forest plantation advisory solutions from Farmonaut (tailored for large-scale and modular in ground or underground irrigation system management with digital oversight).

Automation & Data-Driven Water Management

• Remote scheduling adjusts run times automatically based on forecast or real-time weather and soil data.
• Evaporation and runoff control improves when a controller — not a person on a fixed schedule — sets rate, duration and timing.
• Fertigation through drip lines combines nutrient delivery with irrigation, cutting the nutrient runoff that plain broadcast fertilizing risks.
• Compliance recordkeeping — automated logs from satellite-based monitoring help operations document water use for regulatory reporting.

Measure and reduce your operation’s carbon footprint with Farmonaut’s tool—enabling climate-smart irrigation management for all system types.

Satellite-Based Irrigation Monitoring

Whichever system type you install, the harder ongoing problem is knowing whether it’s actually working across an entire field or property rather than just at the point where you happen to be standing. Satellite imagery platforms help by:

• Detecting irrigation system failures or leaks across sectors
• Tracking vegetation vigor and flagging moisture-stress zones before they show visibly
• Advising corrective changes to water application by zone
• Evaluating post-irrigation effects on productivity, erosion control, and reclamation progress

Frequently Asked Questions

Conclusion

The choice between in-ground, above-ground and underground irrigation comes down to how much upfront cost you’ll accept in exchange for water efficiency and root-zone precision. USDA’s 2023 survey puts real numbers on the stakes: 212,714 US farms irrigating 53.1 million acres, applying 81 million acre-feet of water at $3.3 billion in pumping energy costs, with 54 percent of that water coming from groundwater wells that don’t refill overnight. Whichever system you pick — a DIY surface-drip bed, a zoned in-ground sprinkler system, or a buried subsurface drip network — the underlying method that has held since the qanat is the same: get water below the surface and close to the root, and you lose less of it along the way. Check USDA NASS’s Newsroom page for the next survey update, expected around October 2025 with 2024 figures, to see whether that groundwater share and irrigated acreage keep moving in the direction they have since 2018.
