How to Choose a Well Driller in Tulare County, CA

Drilling or servicing a well is a big expense, and mistakes are hard to undo: a badly sealed well can contaminate groundwater, and a pump set wrong can fail early. This guide covers how to choose a well driller in Tulare County, CA: how to check the license, what permits to ask about, what belongs in the contract, and what should make you walk away. We do not recommend or endorse any particular company. Vetting is yours, so use this checklist.

Check the C-57 license

California Water Code section 13750.5 says no person may dig, bore, or drill a water well, or deepen, alter, or abandon one, unless the person responsible for the work holds a C-57 Water Well Contractor’s License. The Contractors State License Board (CSLB) describes the C-57 classification as one that “installs and repairs water wells and pumps by boring, drilling, excavating, casing, cementing and cleaning to provide a supply of uncontaminated water.”

Use the License Check tool on cslb.ca.gov and enter the license number or business name. Do not rely on a number the company gives you without looking it up.
Confirm the license is active, not expired or suspended, and that it lists the C-57 classification for drilling work.
Look at the bond and workers’ compensation information on the CSLB record, and any complaints or disciplinary actions listed.
For a pump-only job, ask which license the company holds. CSLB has said some other license classifications are limited to pump work, so a pump specialist may not be a driller, and a driller can usually also service pumps.
Check that the name on the license matches the company on the contract and the truck.

Permits in Tulare County

Well construction in unincorporated Tulare County is regulated under Part IV, Chapter 13 (“Construction of Wells”) of the Tulare County Ordinance Code. Recent county environmental notices for domestic wells say new wells are built under the rules and permit requirements of the Tulare County Health and Human Services Agency’s Environmental Health Division, and the ordinance also covers deepening and destroying wells. In practice:

Ask for a permit before work starts. Ask the driller whether a county permit is needed for your job, who applies, and who pays the fee. Put the answer in the contract.
Replacement wells and setbacks. County notices for recent replacement wells describe cases where the new well could not meet setback distances from a septic leach line or animal enclosure. The county handled these with an administrative variance and a longer annular seal, often 50 to 100 feet. Ask your driller whether your site has setback issues.
Inside a city. If your property is inside city limits, ask both the city and the county which office handles well permits, since we have not confirmed how city wells are handled.
Abandoning an old well. A failed well may need to be properly destroyed. Ask who does it and who pays.

Verify with the county. We have not confirmed current permit fees, forms, or processing times. Call or visit the Environmental Health Division or the county website before you rely on any of this.

Groundwater rules for new wells (SGMA)

Much of the Tulare County valley floor sits in groundwater subbasins managed under the Sustainable Groundwater Management Act (SGMA) by local groundwater sustainability agencies. How those agencies take part in well permitting has changed in recent years and has focused mostly on larger agricultural and commercial wells. The rules that apply to a small household well on your parcel can differ, so ask the county Environmental Health Division, and ask your driller whether any groundwater agency review, fee, or reporting applies. Do not assume.

The well completion report

California law (Water Code section 13751) requires the person who does the work to file a well completion report with the Department of Water Resources within 60 days of finishing. The report includes the well log, construction details, and sealing methods. Ask the driller to confirm they will file it and to give you a copy. It helps if you ever sell the property, deepen the well, or need to show what is in the ground.

Get more than one quote

Two or three written quotes show you where the numbers and assumptions agree. Compare:

Planned depth, casing diameter and material, and the length of the annular seal
Pump size and type, wire, drop pipe, pressure tank, and controls
Who handles the permit, testing, and disinfection
What happens if water is not found at the planned depth, and what a deeper hole costs per foot
Start date and expected duration
Warranty on parts and labor

Our cost guide and pump guide give planning ranges to judge each quote.

Red flags

No C-57 license, or a number that does not check out on CSLB.
Cash-only or large upfront payments. Payments should follow a written schedule tied to work completed.
No written quote or contract. A handshake deal on a five-figure job is a problem.
A guarantee of water or flow. Honest drillers talk about likelihood, not certainty.
Pressure to skip the permit or “we do not need to file anything.”
Door-knocking after news of dry wells. Be wary of out-of-area operators who show up unsolicited in a drought.
Prices far above or below the others. A very low bid may mean a shorter seal, thinner casing, or an unlicensed crew.
Refusal to share license, insurance, or references.

Questions to ask every company

What is your C-57 license number? (Then check it.)
What depth do you expect, and why? Which nearby wells are you basing that on?
Do I need a county permit, and who applies?
What casing, seal, and pump are you proposing, and why?
What happens if you do not find water, or find too little?
When can you start, and how long will the job take?
Will you file the well completion report and give me a copy?
What is the payment schedule?
Can I see your insurance certificate and talk to recent customers?

The contract

Get everything in writing: scope, price, per-foot rates for extra depth, payment schedule, start and finish dates, materials, who handles permits, testing, and cleanup, warranty terms, and what happens with change orders. If anything is unclear, ask an attorney to read it, or contact CSLB with questions about contract rules for your type of job. If something goes wrong, you can file a complaint with CSLB against a licensed contractor.

When you are ready, request quotes and compare using this checklist. If your well just went dry, read dry well help in Tulare County first.

Frequently asked questions

What license does a well driller need in California?

California law requires the person responsible for drilling, deepening, or destroying a water well to hold a C-57 Water Well Contractor's License. CSLB describes the C-57 classification as covering installing and repairing water wells and pumps. Check any company on the CSLB License Check tool before you sign.

Who issues well permits in Tulare County?

Well construction in the county is governed by Chapter 13 of the Tulare County Ordinance Code, and county notices point to the Health and Human Services Agency's Environmental Health Division for permit requirements. Confirm with the county which office and form apply to your address.

Who pulls the permit, me or the driller?

It varies. Ask the driller in writing who applies for the permit, who pays the fee, and what happens if the county asks for changes. Do not let work begin without knowing.

Should I pay a big deposit up front?

Be cautious. Payments should follow a written schedule tied to work completed. Ask CSLB or an attorney what is allowed for your type of contract, since rules differ by contract type.

What if the driller does not find water?

Ask before you sign. The contract should say what you owe for a dry hole, a low-yield well, or a change in depth, and who decides whether to keep drilling.
