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 Corona's Citrus Country
They didn't call Corona the “Lemon Capital of the World” by accident. Founded in 1886 at the height of Southern California's citrus boom, the colony of South Riverside — soon renamed Corona — planted its first grove under Patrick Harrington and never looked back. By the 1930s the Foothill Lemon Company alone shipped three-quarters of a million boxes a year, and in 1953 the city packed a record 3,391 carloads of fruit. That citrus heritage, nestled in the Temescal Valley at the foot of the Santa Ana Mountains, still lives on in the lemon and orange groves that dot the hillsides and the Mediterranean climate that made them possible.
Southern California Well Service has spent more than thirty years keeping Riverside County growers in water. As a licensed C-57 water well drilling contractor, we drill, equip, and maintain the high-capacity agricultural wells that Corona citrus depends on — and we know the Temescal Valley's mix of alluvial fill and hard granite better than any out-of-area outfit.
What Corona Citrus Demands From a Well
Citrus is a year-round, high-water crop, and Corona's hot, dry summers push demand to the limit. A mature lemon or orange tree can use 50 to 75 gallons a week in peak season, and a full acre of bearing trees commonly needs three to four acre-feet annually. For a typical 10-acre block that translates to a sustained 25 to 40 GPM through the irrigation season; larger commercial groves often need 50 GPM or more.
Because citrus never truly goes dormant here, you can't simply shut the water off in winter. Trees need steady moisture at bloom and fruit set in spring, heavy supply through summer, and protection from stress in fall. A well must be sized to that peak demand, not the comfortable average, or the trees fall behind in August exactly when they can least afford it.
Sizing and Designing a High-Capacity Citrus Well
A well-built ag well balances depth to a reliable water-bearing zone, the sustainable yield of that zone, the pump and motor sized to your target GPM and pressure, and the storage that buffers the trees against pump cycling. In the Temescal Valley, productive wells often draw from alluvial deposits along the drainages, while properties up against the Santa Ana foothills may have to penetrate fractured granite to find water.
We recommend a test hole and a step-drawdown pumping test before committing to a pump. That tells us the well's true sustainable yield so we can match a submersible turbine pump and motor that delivers flow without over-pumping and prematurely dropping the water column. For grove irrigation we usually feed a storage tank and booster system into drip lines or micro-sprinklers — the most efficient, filterable, and automatable way to water citrus root zones.
Water Quality Matters — Citrus Is Sensitive
Citrus is among the more salt-sensitive tree crops, so three water-quality factors deserve attention in any Corona 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.
The mineral-rich groundwater common to the Inland Empire also leaves 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 Heritage Trees to Working Groves
Corona's citrus today ranges from a handful of legacy lemon trees on a homestead lot to multi-acre commercial blocks, and each scale needs a different solution. A small backyard grove may be served well by a modest pump and a simple drip schedule, while a commercial operation needs a robust high-capacity well, ample storage, and automated zones to irrigate efficiently overnight when evaporation is lowest. We design to the grove, not to a one-size template — matching pump, tank, filtration, and controls to the trees you actually grow and the water your site can sustainably yield. Getting that balance right is the difference between a system that fights you every summer and one that quietly does its job for decades.
Efficient scheduling matters as much as raw capacity. Watering deeply and less often encourages citrus to root deeper and tolerate heat, while shallow daily watering wastes water and invites root disease. We help growers pair their well with controllers and soil-moisture sensors so each irrigation set delivers exactly what the trees need — protecting yield while keeping pumping costs and groundwater draw in check.
Common Well Problems We See Around Corona
After decades in Riverside County, the issues we see most in Corona are predictable: pump failures from hard-water mineral buildup, pressure-tank trouble, declining yield as drought drops the water table, iron staining and sulfur odor, and electrical faults from rural power swings. Most are manageable with the right maintenance and early diagnosis.
Maintenance and When to Call a Pro
A grove well is a major asset, and routine care extends its life. We recommend an annual check of pump performance, pressure settings, and amperage draw; periodic water testing; and quick attention to any drop in flow, which is usually the first warning of a failing pump or fouled screen. When yield falls from mineral encrustation or a tightening formation, hydrofracturing can reopen fractures around the borehole and restore production at a fraction of a new well's cost. Call us when you notice falling flow or pressure, air at the emitters, rising power bills, discolored water, or a short-cycling pump — and call before you plant a new grove, when siting and sizing pay off most. Our diagnostic visit is $125, credited toward any work.

Frequently Asked Questions
How many GPM does a Corona citrus grove well need?
A 10-acre grove typically needs a sustained 25 to 40 GPM through the irrigation season, and larger commercial blocks often require 50 GPM or more. We size pumps to peak summer demand so your trees never fall behind in the heat.
How deep are agricultural wells in the Temescal Valley?
It varies. Wells along the valley drainages often draw from alluvial deposits, while properties against the Santa Ana foothills may need to penetrate fractured granite. A test hole determines the true depth to a reliable water-bearing zone before we finalize the design.
Can well water harm my citrus trees?
Yes. Citrus is salt-sensitive, and high salinity, boron, or chloride can cause leaf burn, stunting, and reduced 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. Declining yield is frequently caused by a worn pump, fouled screen, or mineral encrustation. Hydrofracturing can restore production for $3,000 to $8,000, far less than a new well. A diagnostic visit finds the real cause first.
What does a new agricultural well cost near Corona?
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 service for groves that lose water?
Yes, same-day emergency response is available because heat-stressed citrus can't wait. Call (760) 440-8520 or text (760) 219-5877.
