Let's be upfront, because it would be dishonest not to be: Coronado is not well country. The city sits on a sandy tombolo across San Diego Bay, joined to the mainland by the long, narrow Silver Strand, and essentially every property on the island is served by municipal water. Private drinking-water wells here are rare. You will not find rows of backyard wells the way you would in the county's backcountry. So if a marketing pitch tells you that every Coronado home needs a well inspection, treat it skeptically.
What does exist in Coronado is a small number of irrigation and landscape wells serving larger grounds, plus the occasional legacy well on an older parcel. Those wells are worth inspecting when present, especially given the sandy, salt-influenced ground they sit in. But the bigger reason Coronado residents call Southern California Well Service is different: many islanders own a second home, a ranch or a rural parcel elsewhere in San Diego County — in Ramona, the mountain communities, or the desert fringe near Anza — where private wells are the everyday reality. That is where our work usually takes us, and we are glad to serve Coronado owners wherever their well happens to be.
Whether your well is one of the rare landscape wells on the island or a workhorse supply well on a distant property, the inspection is the same disciplined process, and the report is the same thorough document. What changes is the emphasis: on a sandy coastal site we watch for sand and salinity, while on a granite-country parcel we focus on depth, casing and yield.
Our Full Well Inspection Checklist
Every inspection, wherever the well sits, works through the same component-by-component checklist:
- Pump performance — flow in gallons per minute, working pressure through the cycle, and motor amp draw to expose a pump that is struggling. On sandy coastal wells, sand infiltration is a common pump-killer we specifically look for.
- Pressure tank and switch — air charge, bladder condition, and cut-in/cut-out settings, plus a check for short-cycling that shortens motor life.
- Electrical, control box and wiring — inspection of the control box, breakers, connections and grounding, with extra scrutiny for corrosion in the salt-laden coastal air.
- Static and pumping water levels — resting level, drawdown under load, and a timed recovery test to establish real, sustainable yield.
- Water quality sampling — bacteria (total coliform and E. coli), nitrates, general minerals, and — on coastal wells — total dissolved solids and chloride to check for salinity.
- Wellhead, sanitary seal and casing — examination of the cap, seal and above-grade casing for cracks, gaps and corrosion that would admit contaminants or, near the coast, saltwater.
Pre-Purchase Inspections vs. Annual Care
Pre-purchase and real-estate inspections matter most for Coronado owners who are buying property elsewhere. When you close on a rural or backcountry parcel with a well, the buyer needs to know what the well can do, the seller needs to clear any surprises, and the lender and escrow officer usually require documentation that the well produces enough clean water safely. Our real-estate report is written to satisfy all of them, and San Diego County title companies and lenders accept it.
Annual and preventive inspections are the practical choice for a well you already own, particularly one you do not visit every day. A distant well on a second property is exactly the kind that fails unnoticed — a pressure switch drifts, a seal cracks, a pump loses output — until the day you arrive and nothing works. A yearly inspection keeps that well dependable and catches small problems before they become expensive ones. For the rare Coronado landscape well, the same logic applies on a seasonal cycle.
Water Testing and the Silver Strand
Water testing on the island is shaped by the sand and the sea. Coronado's tombolo is built from sand deposited across the mouth of the bay, and any shallow well in that material faces two coastal hazards. The first is sand infiltration, which wears pump components and clouds the water. The second is salt intrusion: with the bay on one side and the ocean on the other, the water table is close and salty, so we screen total dissolved solids and chloride whenever we test a coastal well. Bacteria and nitrate testing remain standard everywhere. On the rural properties many Coronado owners hold, we shift the panel toward the contaminants that matter in granite and alluvial country, tailoring each test to the site rather than running a generic screen.

County
Based on California DWR well completion reports. Coronado's average well depth is 400 feet shallower than the San Diego County average of 450 feet.
The 57 wells on record for the Coronado area average just 50 feet deep — among the shallowest in the county, which makes sense for a sandy coastal spit where the water table sits high. The 13-to-300-foot range spans shallow sand-and-alluvium wells near the bay and the deeper wells that reach firmer ground. Shallow coastal wells like these are exactly the ones most exposed to sand and salinity, which is why static level readings, a pumping test and careful water-quality screening are non-negotiable parts of an inspection here.

What Your Report Includes
Every inspection concludes with a written report, not a verbal impression. It documents our findings for each system, includes photographs of the wellhead, equipment and any trouble spots, spells out our recommendations plainly, and attaches itemized estimates for any repairs so you can plan the cost. For a real-estate purchase elsewhere in the county, that report is the file your lender, escrow officer and title company will want. For a well you are keeping, it is the baseline for every future check.
When You Need an Inspection
Schedule one before buying any property with a well; before relying on a well that has sat idle; once a year on an active well as preventive maintenance; and whenever you see warning signs — low or dropping pressure, sand or discoloration in the water, air sputtering from the lines, a pump that never shuts off, or a jump in your power bill. For Coronado residents whose wells are on distant rural land, an annual inspection is simply the most reliable way to keep a well you rarely see in working order.
What It Costs
A well inspection runs $150 to $400 depending on the system. A water quality test is $100 to $300 depending on the contaminants screened. A dedicated flow or yield test is $150 to $350. A diagnostic visit for a specific problem is $125, credited toward any repair you approve. The pricing is the same whether we are looking at a rare Coronado landscape well or a rural property you own elsewhere in San Diego County, and we quote before we start.
When to Call a Professional
A homeowner can reset a breaker, adjust a pressure switch or check a pressure tank's air charge. Everything past that — pulling a pump, working in the control box, opening the casing — calls for a licensed contractor because of the risk of injury, dropped equipment and contamination. As a licensed C-57 pump contractor with more than 30 years in the field, we handle that work safely, and we service all major pump brands including Franklin Electric, Grundfos, Goulds (Xylem) and Sta-Rite (Pentair).

Frequently Asked Questions
Are there really private wells in Coronado?
Honestly, very few on the island itself. Coronado sits on a sandy tombolo connected to the mainland by the Silver Strand, and essentially the entire city runs on municipal water. Private drinking-water wells are rare here. The wells that do exist tend to be irrigation or landscape wells serving larger grounds. Most of our Coronado customers actually reach us because they own additional property elsewhere in San Diego County, in the rural and outlying areas where wells are the norm.
I live in Coronado but own a rural property with a well. Can you help?
Yes, and that is one of the most common reasons Coronado residents call us. We serve well owners across the greater San Diego County region, including the backcountry areas where second homes, ranches and rural parcels rely on private wells. We can inspect, test and service that well and give you a full written report even though the property is well outside the city.
What would a landscape or irrigation well inspection in Coronado include?
We measure pump flow in gallons per minute, verify pressure and motor amp draw, read static and pumping water levels with a recovery test, inspect the pressure tank and switch, examine the control box and wiring, check the wellhead, casing and sanitary seal, and sample the water. Because Coronado sits on a sandy coastal spit, we pay particular attention to sand infiltration and salinity in any well here.
Does the sandy Silver Strand geology affect wells?
It does. Coronado's tombolo is built of sand, and any shallow well in that material is prone to sand infiltration that wears pumps and clouds water, and to salt intrusion given how close the water table sits to the bay and ocean. We screen for total dissolved solids and chloride and check pump and screen condition closely on coastal wells.
How much does a well inspection cost?
A well inspection runs $150 to $400, a water quality test is $100 to $300 depending on the panel, and a flow or yield test is $150 to $350. A diagnostic visit for a specific issue is $125, credited toward any repair you approve. Pricing is the same whether the well is a rare Coronado landscape well or a rural property you own elsewhere in the county.
When should I have a well inspected?
Before buying any property that has a well, before relying on a well that has sat unused, once a year as preventive maintenance, and any time you notice trouble such as low pressure, sand or discoloration, a pump that runs constantly, or a rising electric bill. For Coronado owners with rural or second properties, an annual inspection is the simplest way to keep a distant well dependable.
