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 Redlands Citrus Growers
For more than seventy-five years, Redlands stood as the largest navel-orange-producing region in the world. E. J. Waite planted the city's first grove in 1882, and by the late 1930s more than 15,000 acres of citrus surrounded a downtown packed with fruit houses shipping thousands of railcars of fruit every season. While subdivisions have replaced many of those historic groves, citrus is still woven into the identity of this corner of San Bernardino County — and the growers who keep heritage trees and working orchards alive still depend on the same thing the original colonists did: a dependable, high-capacity well.
Southern California Well Service has spent more than thirty years drilling, equipping, and maintaining agricultural wells across the Inland Empire. We are a licensed C-57 water well drilling contractor, and we understand the specific demands of irrigating citrus in the Redlands area — from the alluvial fans below the San Bernardino Mountains to the harder bedrock that fringes the valley.
How Much Water a Redlands Citrus Grove Really Needs
Mature citrus is a thirsty, year-round crop. In the dry heat of an Inland Empire summer, an established orange or lemon tree can transpire 50 to 75 gallons a week, and a full acre of bearing trees commonly requires three to four acre-feet of water annually. Translate that into pumping terms and the numbers add up quickly: a 10-acre grove may need a sustained 25 to 40 gallons per minute (GPM) through the irrigation season, and larger commercial blocks frequently call for 50 GPM or more.
Because citrus has no true dormancy in this climate, water cannot simply be shut off in winter. Trees need moisture during bloom and fruit set in spring, steady supply through the brutal summer, and protection against root stress in fall. A well that “keeps up” in April but draws down in August is not sized correctly for a Redlands grove. Sizing a well to peak summer demand — not average demand — is the single most important design decision a grower makes.
Sizing and Designing a High-Capacity Citrus Well
A properly engineered agricultural well balances four variables: the depth to a reliable water-bearing zone, the sustainable yield of that zone, the pump and motor selected to deliver target GPM at the right pressure, and the storage and delivery system that buffers the trees against pump cycling. In the San Bernardino Valley, many productive ag wells draw from the deep alluvial deposits of the upper Santa Ana basin, while properties closer to the foothills may have to penetrate weathered granite to reach water.
We typically recommend a test hole and a step-drawdown pumping test before finalizing the pump. That data tells us the well's true sustainable yield so we can match a submersible turbine pump and motor that hits your flow target without over-pumping and prematurely lowering the water column. For grove irrigation we usually pair the well with a storage tank and booster system feeding drip lines or micro-sprinklers — the most efficient way to deliver water to 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. Three water-quality factors deserve close attention in any Redlands well:
- Salinity (total dissolved solids): Elevated salts accumulate in the root zone and stunt growth and yield over time.
- Boron: Toxic to citrus even at moderate concentrations — leaf-tip burn is a classic symptom.
- Chloride: Causes characteristic leaf scorch and reduces fruit quality.
The mineral-rich groundwater common to the Inland Empire can also leave hard-water scale that clogs drip emitters and shortens pump life. We test well water before recommending treatment, and we can design filtration or blending strategies that protect both your trees and your irrigation hardware.
Drought, Groundwater, and Long-Term Reliability
San Bernardino County has lived through repeated multi-year droughts, and each dry cycle pulls regional water tables lower. For citrus growers that means a well drilled to yesterday's water level may struggle tomorrow. When we design or rehabilitate a Redlands grove well, we build in margin: setting the pump deep enough to tolerate seasonal and drought drawdown, and recommending storage so the well can recharge between irrigation sets rather than being run continuously at the edge of its capacity. Pairing the well with efficient drip or micro-sprinkler delivery and a soil-moisture-based schedule stretches every gallon — critical both for tree health and for staying within sustainable groundwater limits.
Common Well Problems We See Around Redlands
After decades of service in San Bernardino County, the issues that bring growers to us most often are predictable: pump failures driven by hard-water mineral buildup, pressure-tank problems, declining yield during multi-year droughts as the regional water table drops, iron staining and sulfur odor, and electrical faults from rural power fluctuations. Many of these are manageable with the right maintenance schedule and early diagnosis.
Maintenance That Protects Your Investment
A grove well is a five- and six-figure asset, and routine care extends its life dramatically. We recommend an annual inspection of pump performance, pressure settings, and amperage draw; periodic water testing for salinity and minerals; and attention to declining flow, which is often the first warning of a failing pump or a fouled screen. When yield drops because of mineral encrustation or a tightening formation, hydrofracturing — injecting high-pressure water to reopen fractures around the borehole — can restore production at a fraction of the cost of a new well.
When to Call a Professional
Call us when you notice a steady decline in flow or pressure, air spitting from emitters, rising power bills with no change in run time, cloudy or discolored water, or a pump that short-cycles. For a new grove, call before you plant — siting and sizing the well correctly from the start saves far more than it costs. Our diagnostic visit is $125, credited toward any work we perform.

Frequently Asked Questions
How many gallons per minute does a citrus grove well need in Redlands?
A 10-acre grove typically needs a sustained 25 to 40 GPM through the irrigation season, while larger commercial blocks often require 50 GPM or more. We size pumps to peak summer demand, not average demand, so your trees never fall behind during the hottest months.
How deep are agricultural wells around Redlands?
Depth varies with location. Many productive ag wells tap the deep alluvial deposits of the upper Santa Ana basin, while properties nearer the foothills may need to penetrate weathered granite. A test hole tells us the true depth to a reliable water-bearing zone before we finalize the design.
Can well water damage citrus trees?
Yes. Citrus is salt-sensitive, and high salinity, boron, or chloride in well water can cause leaf burn, stunting, and reduced yield over time. We test your water and can recommend filtration or blending to protect the trees.
My grove well's output has dropped — do I need a new well?
Not necessarily. Declining yield is often caused by a worn pump, a fouled screen, or mineral encrustation. Hydrofracturing can frequently restore production for $3,000 to $8,000, far less than a new well. A diagnostic visit identifies the real cause first.
How much does a new agricultural well cost near Redlands?
A turnkey agricultural well generally runs $25,000 to $60,000 or more, depending on depth, casing, and pump specifications. Pump replacements run $3,000 to $8,000. Our $125 diagnostic fee is credited toward any work we perform.
Do you offer emergency service if my grove loses water?
Yes. We offer same-day emergency response when you have no water, because citrus under heat stress can't wait. Call (760) 440-8520 or text (619) 259-0410.
