Citrus Water Requirements
Citrus trees need consistent water for optimal production:
- Young trees: 10-20 gallons per week
- Mature trees: 50-75 gallons per week in summer
- Per acre: Approximately 3-4 acre-feet annually
That translates to serious well capacity requirements for commercial groves.
Grove Well Systems
- Agricultural wells: High-capacity for irrigation demand
- Drip irrigation: Efficient water delivery to root zones
- Micro-sprinklers: Coverage with minimal waste
- Filtration: Keep drip emitters clean
- Automation: Timed irrigation cycles
Water Quality for Citrus
Citrus is sensitive to water quality issues:
- Salinity: High salt damages trees over time
- Boron: Toxic to citrus at moderate levels
- Chloride: Causes leaf burn
We can test your well water and recommend treatment if needed.

Agricultural Well Service for Temecula Citrus Growers
Temecula is best known today for its wine country, but the warm days and cool nights of this southwestern Riverside County valley have long supported citrus and other tree crops as well. Out in the rural reaches of the valley and up in the surrounding hills, groves of oranges, lemons, and mandarins depend on private wells — municipal water rarely reaches the working agricultural parcels.
Southern California Well Service has spent more than thirty years drilling, equipping, and maintaining agricultural wells across Riverside County. As a licensed C-57 water well drilling contractor, we drill and service the high-capacity wells that local citrus depends on, and we know the area's terrain and groundwater far better than any out-of-area outfit.
How Much Water a Temecula Citrus Grove Needs
Citrus is a thirsty, year-round crop. In Temecula's summer heat a mature orange or lemon tree can transpire 50 to 75 gallons a week, and a full acre of bearing citrus commonly needs three to four acre-feet of water annually — roughly a million gallons per acre per year. For a 10-acre grove that means a sustained 25 to 40 GPM through the irrigation season, with larger commercial blocks needing 50 GPM or more.
Because citrus never fully goes dormant in this climate, water can't simply be shut off in winter. Trees need steady moisture at bloom and fruit set in spring, heavy supply through summer, and protection from stress in fall. We always size a well to peak summer demand, not the comfortable average — a well that keeps up in April but draws down in August is not sized for a working grove.
Sizing and Designing a High-Capacity Citrus Well
A sound agricultural well balances four things: depth to a dependable water-bearing zone, the sustainable yield of that zone, a pump and motor matched to your target GPM and pressure, and storage that buffers the trees against pump cycling. Around Temecula, productive wells often draw from the alluvial deposits of the valley floor, while properties up in the surrounding granite hills may have to penetrate fractured bedrock to reach water; depths vary widely with location, so a test hole is the only reliable way to know your site.
We recommend a test hole and a step-drawdown pumping test before selecting the pump, matching a submersible turbine pump to the well's true sustainable yield without over-pumping and prematurely dropping the water column. For grove irrigation we typically feed a storage tank and booster system into drip lines or micro-sprinklers — the most efficient way to water citrus root zones and the easiest to filter and automate.
Water Quality Matters — Citrus Is Sensitive
Citrus is among the more salt-sensitive tree crops, so three water-quality factors deserve attention in any Temecula well:
- Salinity (TDS): Salts accumulate in the root zone and erode yield over time.
- Boron: Toxic to citrus even at moderate levels — classic leaf-tip burn.
- Chloride: Causes leaf scorch and lowers fruit quality.
Mineral-rich groundwater can also leave hard-water scale that clogs drip emitters and shortens pump life. We test your well water and design filtration or blending that protects both your trees and your hardware.
Drought, Groundwater, and Long-Term Reliability
Riverside County has weathered repeated multi-year droughts, and each dry stretch lowers regional water tables. A well drilled to yesterday's level can struggle tomorrow, so we build in margin — setting the pump deep enough to ride out seasonal and drought drawdown, and adding storage so the well recharges between sets instead of running continuously at the edge of capacity. Combined with efficient delivery and a soil-moisture-based schedule, that approach protects both tree health and the long-term sustainability of your groundwater.
From Backyard Trees to Working Groves
Temecula citrus ranges from a few heritage trees on a homestead to multi-acre commercial blocks, and each scale needs its own design. A small grove may thrive on a modest pump and a simple drip schedule, while a commercial operation needs a robust high-capacity well, ample storage, and automated zones that irrigate overnight when evaporation is lowest. Efficient scheduling matters as much as raw capacity: watering deeply and less often drives roots deeper and builds heat tolerance, while shallow daily watering wastes water and invites root disease. We design to the grove in front of us, matching pump, tank, filtration, and controls to your trees and to the water your site can sustainably yield.
Common Problems, Maintenance, and When to Call a Pro
After decades of service in Riverside County, the issues we see most around Temecula are predictable: pump failures from hard-water mineral buildup, pressure-tank trouble, declining yield as drought drops the water table, iron staining or sulfur odor, and electrical faults from rural power swings. Routine care extends a well's life dramatically — an annual check of pump performance, pressure settings, and amperage draw; periodic water testing; and quick attention to any drop in flow, usually the first warning of a failing pump or fouled screen. When yield falls from mineral encrustation or a tightening formation, hydrofracturing — injecting high-pressure water to reopen fractures around the borehole — can restore production for a fraction of a new well's cost. Call us when flow or pressure declines, emitters spit air, power bills climb without more run time, water turns cloudy, or the pump short-cycles — and call before you plant a new grove, when correct siting and sizing pay off most.

Frequently Asked Questions
How many GPM does a Temecula citrus grove well need?
A 10-acre grove typically needs a sustained 25 to 40 GPM, and larger commercial blocks often require 50 GPM or more. We size pumps to peak summer demand so the grove never falls behind during the hottest weeks.
How deep are wells around Temecula?
Depth varies widely. Valley-floor wells often draw from alluvial deposits, while properties in the granite hills may need to penetrate fractured bedrock. A test hole and pumping test are the only reliable way to determine depth and sustainable yield for your site.
Can well water harm my citrus trees?
Yes. Citrus is salt-sensitive, and high salinity, boron, or chloride can cause leaf burn, stunting, and lost yield. We test your water and can recommend filtration or blending to protect the trees.
My grove well's yield is dropping — do I need a new well?
Often not. Worn pumps, fouled screens, or mineral encrustation are common culprits, and hydrofracturing can restore production for $3,000 to $8,000. A diagnostic visit finds the real cause before you spend on a new well.
What does a new agricultural well cost near Temecula?
A turnkey agricultural well generally runs $25,000 to $60,000 or more depending on depth, casing, and pump. Pump replacements run $3,000 to $8,000, and our $125 diagnostic fee is credited toward any work.
Do you offer emergency well service in Temecula?
Yes. Same-day emergency response is available because heat-stressed citrus can't wait. Call (760) 440-8520 or text (619) 259-0410.
