If you are trying to work out what well drilling costs in Tulare County, CA, the honest answer is that depth drives most of the price, and the pump and other equipment add a lot more. This guide breaks the cost into pieces so you can read a driller's quote critically.
A note on the numbers: every figure on this page is a general planning estimate, not a quote and not a local price survey. Most published well-cost guides are national, they disagree with each other, and few give Central Valley prices for wells this deep. We combined several of them (listed below) into labelled ranges. Prices vary by driller, depth, casing, and time, and they change. Use these ranges only to judge whether a quote looks wildly high or low, then get written quotes for your property. We do not name or endorse particular companies.
How deep will the well be?
Depth is the biggest unknown. A USGS study of groundwater in the Tulare, Kaweah, and Tule basin area reported that domestic wells there are typically drilled to roughly 150 to 500 feet. County environmental notices for single-home wells near Porterville and in the Delano-Earlimart area describe wells planned at around 500 to 600 feet, and during droughts, owners have often had to drill deeper to reach water. A driller will use records of nearby wells, local groundwater levels, and your location to estimate depth, but cannot promise it.
Planning ranges by item
| Item | Typical planning range (estimate) | What usually drives it |
|---|---|---|
| Drilling and casing | Roughly $30 to $70 per foot, installed | Depth, casing diameter and material, formation (sand, gravel, clay, rock), driller availability |
| Pump system (submersible pump, wire, drop pipe, installation) | Roughly $1,500 to $5,000, more for very deep or high-demand wells | Depth to water, horsepower, pipe and wire length, constant-pressure controls |
| Pressure tank and controls | Roughly $300 to $1,500 | Tank size, switch or controller type, plumbing changes |
| Permit | Guides cite roughly $350 to $700; ask the county for the current fee | County fee schedule, any inspection or variance |
| Electrical, trenching, and plumbing to the house | Varies widely; often a few thousand dollars on a long run | Distance from the well to the house and panel, trenching, existing plumbing |
| Water testing and disinfection | Usually a modest line item; ask the driller what is included | Which tests you want, lab fees |
| Deepening an existing well | Roughly $35 to $85 per foot of added depth, plus pump work | Condition of the casing, how deep it must go, whether the casing can be extended |
The per-foot range comes from three kinds of sources that overlap: general national guides that put drilling plus installation at about $25 to $65 per foot, a statewide table that lists California at about $25 to $50 per foot, and a 2022 State Water Board example of a Central Valley driller quoting $40 to $60 per foot in other San Joaquin Valley counties. We rounded up the top end because deep, larger-diameter wells cost more per foot than the shallow wells most national guides describe.
Example budgets
These are made-up scenarios using the planning ranges above, to show how a budget adds up. They do not describe any real property or quote, and they leave out electrical and plumbing runs, water treatment, and cleanup. Add a contingency of roughly 10 to 20 percent.
| Item | A: Shallower well, about 200 ft | B: Mid-depth well, about 300 ft | C: Deep well, about 500 ft |
|---|---|---|---|
| Drilling and casing at $30 to $70 per ft | $6,000 to $14,000 | $9,000 to $21,000 | $15,000 to $35,000 |
| Pump system | $1,500 to $3,500 | $2,000 to $4,000 | $3,000 to $5,000 |
| Pressure tank and controls | $300 to $1,500 | $300 to $1,500 | $300 to $1,500 |
| Permit | $350 to $700 | $350 to $700 | $350 to $700 |
| Rough total | $8,150 to $19,700 | $11,650 to $27,200 | $18,650 to $42,200 |
For a sanity check, a 2015 state legislative background paper on drought emergency services described a new well as costing $15,000 or more, and national guides put 300 to 400 foot wells at roughly $10,000 to $25,000 for drilling and casing alone. Costs have risen since 2015, so treat the budgets above as a starting point and not a ceiling.
What drives the price
- Depth. Every extra foot adds drilling, casing, and a longer pump setup.
- Casing size and material. A larger casing for higher flow, or steel in place of PVC, costs more per foot.
- Formation. Sand and gravel layers, clay, and hard rock drill differently, and some need extra work to keep the hole open.
- Setbacks and sealing. Rules about distance from septic systems and animal enclosures can require a longer annular seal, and county notices for recent replacement wells mention seals of 50 to 100 feet. That adds cost. See our guide to choosing a well driller.
- Wait time. In dry years, drillers have had long waiting lists, and rushing may cost extra or limit your choices.
- Water quality. If the water needs treatment, that is a separate cost from the well.
- Abandoning an old well. A failed well may have to be properly destroyed under county rules. Ask who handles that and what it costs.
Ways to avoid overpaying (and underpaying)
- Get two or three itemized written quotes. Compare depth assumptions, casing, pump size, and what happens if water is not found at the planned depth.
- Ask about the replacement-or-deepen question. If your well went dry, a driller can tell you whether lowering the pump, deepening, or drilling new makes more sense. Deepening is not always possible or lasting.
- Check the license first. California requires a C-57 license to drill, and a low price from an unlicensed operator is a red flag. See the choosing a driller guide.
- Check for help. If your well went dry because groundwater levels dropped, some assistance for replacement wells has existed for eligible households. See dry well help in Tulare County.
- Do not ignore the pump. A new well with an old pump can fail early. Our pump cost guide explains what replacement runs.
Sources behind these ranges
We drew on the Bob Vila well drilling cost guide (2023), HomeGuide cost data as summarized by eLocal, a 2022 California State Water Board appendix on domestic wells, a USGS summary of domestic well depths in the Tulare, Kaweah, and Tule basin area, and county environmental notices for Tulare County domestic wells. None of these is a local price survey, which is why we show ranges and recommend written quotes.
Frequently asked questions
How much does a new domestic well cost in Tulare County?
As a rough planning range, a typical domestic well here may total somewhere from around $10,000 to $40,000 or more once drilling, casing, pump, tank, and permit are included, depending mostly on depth. These are general estimates, not quotes. Published sources for the Central Valley are thin, so the only reliable number is a written quote from a licensed driller.
How deep are wells near Visalia?
A USGS study of the Tulare, Kaweah, and Tule basin area reported that domestic wells there are typically drilled to roughly 150 to 500 feet. Individual wells can be shallower or deeper, and county records show some single-home wells planned near 500 to 600 feet. Your depth depends on your location and local groundwater.
Is the per-foot price the whole cost?
No. Drilling and casing are usually quoted per foot, but the pump, wire and drop pipe, pressure tank, electrical work, permit, disinfection, and water testing are often separate. Ask each driller for an itemized written quote.
Do I need a permit to drill a well in Tulare County?
Generally yes. Well construction in the county is regulated under Chapter 13 of the Tulare County Ordinance Code, and county notices point to the Environmental Health Division for permit requirements. Confirm what applies to your address with the county before work starts.
Can drilling guarantee water?
No. Drillers can estimate depth from nearby wells and local conditions, but the result is not guaranteed. Ask how the contract handles a dry hole or a low-yield well before you sign.
