Well Data: Fontana, California

With 132 wells on record, Fontana has a moderate well infrastructure. The wide depth range of 15 to 1225 feet reflects the varied terrain and geology across Fontana's landscape. Shallower wells typically tap into alluvial aquifers near drainages, while deeper wells penetrate mixed alluvial deposits and crystalline basement rock of the Peninsular Ranges to reach more reliable water sources.

At an average depth of 449 feet, drilling in Fontana typically costs between $20,205 and $33,675 depending on formation hardness and casing requirements. See detailed well depth data for Fontana ➡

Drilling Conditions in Fontana

Well drilling in Fontana typically encounters mixed alluvial deposits and crystalline basement rock of the Peninsular Ranges. The deeper average depth means drilling often takes 3-5 days depending on formation hardness. Hard granite formations may require air rotary or mud rotary methods to maintain borehole stability.

San Bernardino County well permits are issued through the Environmental Health Services department. Turnaround is typically 2-4 weeks. We handle the entire permit process for Fontana properties.

Well Drilling in Fontana, San Bernardino County: What Property Owners Need to Know

If you have been searching for "well drilling near me" or looking up the "cost to drill a well in Fontana," you have already taken the right first step. Fontana sits squarely in San Bernardino County, one of the largest counties in the United States, and the groundwater beneath this Inland Empire city has supplied ranches, agricultural operations, and residential properties for well over a century. Southern California Well Service (SCWS) is a licensed C-57 contractor with more than 30 years of experience drilling and servicing wells throughout the region. Whether you are on a rural parcel off Beech Avenue, a property near the base of Lytle Creek Road, or anywhere in the Fontana sphere, our team knows this ground — literally.

Drilling a new water well in Fontana is a significant investment, but it can provide long-term independence from municipal water bills and give you a reliable private water supply. In this guide we walk through every phase of the process, from the first site visit through final state filing, so you know exactly what to expect before the first bit of drill steel touches the soil.

The Turnkey New-Well Process: Step by Step

1. Site Assessment and Geology Review

Before any equipment rolls onto your property, one of our experienced well consultants conducts a site assessment. We review local well records filed with the California Department of Water Resources (DWR), evaluate neighboring wells for depth and yield data, and inspect your parcel for setback compliance — wells must be sited a minimum distance from septic systems, fuel tanks, drainage ditches, and property lines per state and county requirements. We also review the local geology to determine the most efficient drilling approach for the formations typical in the Fontana area.

2. County Permitting

All new wells in Fontana require a permit issued by San Bernardino County Environmental Health Services before drilling begins. The application requires a plot plan showing the proposed well location relative to all structures and potential contamination sources within 500 feet, proposed casing material, intended use, and estimated pump rate. We handle the entire permit package on your behalf. Permit fees in San Bernardino County typically run $300 to $1,200 depending on well type and anticipated depth. Allow two to four weeks for county review, though timelines can vary. We will not break ground until the permit is in hand.

3. Drilling Method and Rig Selection

Our Gefco rotary drill rig is capable of reaching 1,000-plus feet. In Fontana's upper alluvial zones, mud rotary drilling is often preferred because it stabilizes the borehole walls through the loose, unconsolidated sediments characteristic of the alluvial fan. As the borehole encounters harder crystalline basement rock — granite, gneiss, and related formations common at depth in the San Gabriel foothills area — air rotary methods can be employed to clear cuttings efficiently and reduce wear. Our drillers select the appropriate method or combination based on formation conditions encountered in real time.

4. Expected Depths and Formation Sequence

California DWR well completion records show the depth range for Fontana wells spanning from roughly 15 feet to more than 1,200 feet, with an average near 449 feet. Shallow wells in the 150- to 300-foot range may tap productive zones in the coarse-grained alluvial gravels deposited by the Santa Ana River drainage system and Lytle Creek. Deeper wells — 400 to 800 feet or beyond — penetrate the lower alluvial zones and, in some locations, partially consolidated continental deposits that form part of the Rialto-Colton and Chino groundwater subbasins. We will give you a best-estimate depth range before spudding, based on the records we pull for your specific location.

5. Casing and Well Construction

Once the borehole reaches the target zone, we install the well casing. For most residential wells in this area, we use either PVC casing for shallower completions in softer formations or steel casing for deeper wells or sections that pass through unstable rock. The annular space between the borehole wall and the casing is filled with a grout seal from the surface down to at least 50 feet — a state requirement meant to prevent surface contamination from migrating downward. Perforated casing (screen) is set across the productive water-bearing intervals, and a gravel pack is placed around the screen to support formation material and maximize water flow into the well.

6. Well Development

After casing is in place, the well must be developed — a process that removes the fine particles introduced during drilling and allows the native formation to settle against the screen. We use air surging and pumping to clean the well and assess the sustainable yield. A pump test is typically run to measure gallons per minute and static and pumping water levels. This data is required for the DWR well completion report and for designing the right pump system.

7. Pump and Pressure System Installation

With yield data in hand, we size and install a submersible pump matched to your property's demand — household use, irrigation, livestock, or a combination. We install the drop pipe and wiring, a pitless adapter for sanitary below-grade penetration, a pressure tank, pressure switch, and any needed check valves. We coordinate with your electrician if a new service panel circuit is required. Our goal is a system that runs reliably for decades without excessive cycling or energy waste.

8. Final Inspection and DWR Well Completion Report

San Bernardino County Environmental Health Services may require a final inspection before the well is placed in service. We collect a water sample for laboratory testing of bacteria and common chemical parameters. Once the county signs off, we prepare and file the California DWR Well Completion Report — a legal document that becomes part of the permanent state record and is required by California Water Code for all new wells. You receive a copy for your property files.

Fontana Geology and Groundwater: What the Local Formations Mean for Your Well

Fontana occupies the western edge of the upper Santa Ana River watershed, on the alluvial fan that sweeps southward from the San Gabriel Mountains toward the valley floor. The subsurface geology reflects millions of years of sediment deposition from mountain streams: layers of gravel, sand, and silt alternating with finer-grained clay horizons. These sediments overlie crystalline basement rock — primarily granite and metamorphic formations — that forms the bedrock of the region.

The groundwater basin underlying Fontana is part of a larger system that includes the Rialto-Colton Subbasin to the immediate east and the Chino Groundwater Basin to the west, both of which are recognized by the California Department of Water Resources and managed under adjudication or local groundwater management programs. The Rialto-Colton Fault is a significant hydrogeologic boundary: it acts as a partial barrier to groundwater movement, meaning aquifer conditions can vary noticeably over short distances in the Fontana area. SCWS's familiarity with local well records lets us anticipate these variations when siting and planning your well.

Productive water-bearing zones in the Fontana area generally occur in:

• Coarse alluvial gravels in the upper 150 to 300 feet, often tied to ancient stream channels
• Deeper alluvial and semi-consolidated zones from 300 to 600 feet, which typically yield better water quality and more consistent flow
• Fractured crystalline basement rock at 600 feet and beyond in some locations, though yield in fractured rock can be less predictable

Based on DWR completion records, the average productive residential well in the Fontana area runs roughly 400 to 500 feet, though properties near the mountain front may find water shallower, and properties toward the valley may require deeper drilling to reach dependable yields.

San Bernardino County Permits: Who Issues Them and How Long It Takes

Fontana is within San Bernardino County — not Riverside County — and all well permits are issued by San Bernardino County Environmental Health Services, reachable at 1-800-442-2283. (Note: in some older records and prior versions of this page, Fontana was incorrectly listed as Riverside County; Fontana has always been in San Bernardino County.)

The Environmental Health Services well program handles new well permits, replacement wells, and well destruction permits. Applications can be submitted electronically, by mail, or in person at the San Bernardino County EHS office. Required materials include a plot plan, proposed well specifications, and the permit fee. Some locations require coordination with a local watermaster regarding pumping restrictions before the permit can be approved. We have navigated this process for Fontana properties many times and handle all paperwork on your behalf.

Plan on approximately two to four weeks for permit approval under normal workload conditions, though complex applications or locations near adjudicated basins may take longer. We factor permitting lead time into our project scheduling so there are no surprises on your start date.

What Does It Cost to Drill a Well in Fontana?

The honest answer is that well drilling costs depend significantly on depth, formation hardness, casing requirements, and the pump system you need. Here is how our pricing is structured:

• Turnkey well drilling (including casing, development, and pump installation): $18,000 to $42,000. Wells requiring greater depth due to formation conditions or lower water tables will trend toward the upper end of this range.
• County permit fee: $300 to $1,200, depending on well type and jurisdiction requirements.
• Site assessment / diagnostic fee: $125, which is credited toward the cost of any well work we perform.

Factors that push costs higher in the Fontana area specifically include: encountering hard granite or metamorphic rock before reaching a productive zone (which slows the drilling rate), needing steel casing rather than PVC for structural integrity at depth, and the need for a larger pump system to serve irrigation-scale demand. We provide a detailed written estimate before any work begins so you know exactly what you are committing to.

Many property owners who have been on municipal water find that, over a 10- to 20-year horizon, a private well pays for itself many times over — particularly for properties with large irrigation needs or for homes in areas where water rates have increased sharply.

Why Local Experience Matters in Fontana

The Inland Empire geology is not uniform. A driller who primarily works in San Diego coastal formations or the Mojave Desert may not anticipate how quickly the alluvial gravels pinch out near the Rialto-Colton Fault zone, or how the transition from alluvium to granite basement changes drilling technique requirements. Our 30-plus years of work in San Bernardino County means we have drilled through these formations hundreds of times. We know where water typically sits, where formations tend to be unexpectedly hard, and which zones are likely to yield the cleanest water chemistry.

We are also fully licensed and insured as a C-57 Well Drilling contractor — the California license specific to water well drilling — with license number 1013597. Our 4.9-star Google rating reflects the kind of careful, transparent work we bring to every project, from a single residential well in Fontana to larger agricultural installations across the Inland Empire.

When Should You Consider Drilling a New Well?

Property owners in Fontana and the surrounding San Bernardino County communities typically consider a new well when:

• An existing well has declined in yield and rehabilitation is not cost-effective
• Water quality from an existing well has deteriorated and the zone needs to be abandoned in favor of a deeper, cleaner source
• A property is being developed or subdivided and will not have practical access to a municipal water connection
• High municipal water bills make a private supply economically attractive, especially for agricultural or large-landscape irrigation use
• An existing well casing has failed or is too deteriorated to pump safely

Our $125 diagnostic assessment helps determine which path makes the most sense for your situation — sometimes a wellbore rehabilitation or pump replacement is the right answer; other times a new well is clearly the better long-term investment. Either way, you will not be pressured into a scope larger than your property actually needs.
