Your Well Ran Dry in California: What to Do First, and How to Fix It for Good
If you're on a private well in California and the water just stopped — or the faucet is spitting air, sand, or sputtering water that won't build pressure — the first question isn't "how much will this cost," it's "is the well actually dry, or is something else failing." Those are different problems with very different fixes, and during a dry stretch, a genuinely depleted well is common enough in parts of California that the state runs a dedicated assistance program for exactly this situation. Here's how to tell which one you're dealing with, what to do in the meantime, and what actually solves it.
Is the well dry, or is it the pump or pressure tank?
A failing pump or a waterlogged pressure tank can mimic a dry well almost exactly — short bursts of water, air sputtering from the taps, a pump that short-cycles on and off every few seconds. The difference matters because one is a same-day repair and the other is a groundwater problem no plumber can fix by swapping a part. Our well pump and pressure tank repair guide covers the equipment-failure signs in detail, but the quick way to tell them apart: a failing tank or pump usually still delivers water, just unevenly, and doesn't improve if you stop using it for a few hours. A well that's actually run low on groundwater typically produces fine after resting, then loses pressure again quickly once you run a load of laundry or water the yard — because the water table around the well casing hasn't recovered fast enough to keep up with the pump's draw. If you're not sure which you're looking at, a licensed well contractor can measure the well's static and pumping water levels in under an hour and tell you definitively, which is worth doing before paying for either a pump replacement or a full re-drill.
What to do while you have little or no water
If the well genuinely has run dry, don't wait to plan a permanent fix before addressing today's water needs:
- Report it to the state. California's Household Water Supply Shortage Reporting System, at mydrywell.water.ca.gov, exists specifically for owners of private domestic wells. Reporting takes a few minutes and routes your situation to the resources available in your county — it's also how the state tracks where dry-well clusters are forming, which matters for longer-term groundwater planning in your basin.
- Call your county Office of Emergency Services. The State Water Resources Control Board's SAFER program funds interim relief for households on a documented dry well — hauled water, bottled water, or a temporary on-site storage tank — but it's almost always administered locally through a county OES or a partner nonprofit rather than handed out directly by the state. What's currently available, and whether it's free or subsidized, varies by county and by the severity of that year's drought, so a direct call is the only reliable way to find out what your county offers right now.
- Ask a neighbor on a working well or city connection about a temporary water-sharing line. A garden hose run between properties, sometimes formalized with a simple written agreement, is a common short-term bridge while a permanent fix is arranged — and it's explicitly listed as a recognized interim option in the state's own guidance to well owners.
Why this happens more in California than homeowners expect
Domestic wells fail disproportionately during drought for a structural reason, not bad luck: they're usually shallower and lower-capacity than the agricultural wells drilled nearby, which can keep pumping from deeper in the same aquifer as the water table drops. A widely cited study by Scott Jasechko and Debra Perrone, published in Earth's Future in 2020, documented thousands of Central Valley wells running dry between 2013 and 2018 alone, and found that shallower domestic wells failed at far higher rates than deeper wells drilled in the same areas over the same period. If your well and your neighbor's irrigation well tap the same groundwater basin, theirs reaching deeper is frequently the reason yours went dry first.
The permanent fixes, from cheapest to most involved
Once you know it's a genuine groundwater shortfall rather than equipment failure, a licensed well contractor typically has three levels of fix to price out, each solving a different degree of the problem:
- Lower the pump deeper in the existing casing — if the well was drilled deeper than the pump currently sits, moving it down to a lower point in the same casing can restore adequate supply without any new drilling. This is the cheapest fix when the well's total depth has room for it.
- Add a storage tank and booster pump system — for a well that recovers slowly but does recharge overnight, a large storage tank lets the well trickle-fill it around the clock while a booster pump delivers normal household pressure and flow on demand. This is often the most cost-effective route for a well that isn't truly exhausted, just too slow to keep up with peak household demand.
- Deepen the existing well, or drill a new one — when the aquifer around the current casing has dropped below where the well can reach at all, deepening the existing bore or drilling a new, deeper well nearby is the only fix left. It's also the most expensive, and worth getting more than one bid on given how much depth and geology-specific drilling conditions affect the price.
Whichever route applies, know that well and wellhead work in California falls under the CSLB's C-57 Well Drilling classification, not the general C-36 plumbing license most residential plumbers hold. A plumber can usually handle the house-side work — a new storage tank, a booster pump, and the plumbing connecting it all to your fixtures — but pulling the pump or working inside the casing calls for a licensed C-57 contractor. Verify any contractor's license number directly on the CSLB site before committing; our CSLB license check guide walks through exactly how.
Before you commit to the expensive option
It's worth resisting the urge to jump straight to a new well, since that's the priciest fix and not always the necessary one. Ask a contractor to actually measure your well's recovery rate — how fast it refills after being pumped down — before recommending deepening or redrilling. A well that recovers slowly but steadily is often a good candidate for the storage-tank approach at a fraction of the cost, while one that shows no meaningful recovery over several hours is a stronger case for deepening. If you're also weighing whether to abandon the well altogether and connect to a nearby municipal water main instead, our well-to-city water conversion guide covers what that alternative costs and involves. And once any fix is in place, it's a good moment to also test your water quality — a well disturbed by a dropping water table can pull in sediment or minerals it didn't before; see our private well water testing guide for what to check.
Private wells are common well beyond the state's obvious rural stretches — from the vineyards around Napa and Paso Robles to unincorporated parcels near Redding and across the Central Valley around Fresno and Bakersfield. If your well has gone quiet and you need a second opinion on whether it's the pump, the tank, or the aquifer itself, describe the symptoms on Plumber Comparator and request your free quote — a licensed local contractor can diagnose it and price the right fix before you spend money on the wrong one.
