We read it without touching it.
No drilling, no holes, no excavation, no chemicals. We read what's under your land without touching it, then you drill one precise hole in the right place, instead of a field of dry ones.
On-island · Non-destructive · Independent
Know before you drill.
Before you spend hundreds of thousands of pesos on a well, two Siargao locals survey your land with US-developed seismoelectric technology and give you a written report: estimated depth, indicative yield, and saltwater-intrusion risk, so you drill one precise hole on measured data, not a field of dry ones.
The honest part No drilling, no holes, no disturbing your land: we read what's under it without touching it. We don't drill and we don't promise water; we give you an independent read that improves the odds before you spend, and we put it in writing.
Why Siargao Water
Five reasons it pays to survey first.
Back tomorrow, not on a flight.
We live and surf here. We're back tomorrow, not on a flight from Manila, and as people who care about this island, we want your water decision to be a responsible one, on a coast where freshwater is stressed.
We own no drilling rig.
We own no drilling rig and earn nothing from whether or where you drill. The only thing we sell is an honest read: the kind a bank, an owner, an LGU, or a buyer can trust.
Yield and salt, not just presence.
A US-developed seismoelectric method estimates an indicative yield and reads saltwater-intrusion risk, not just whether water is present. A house well and a resort or farm well are different animals, and on a coastal lot salt is the question.
A document you can file and defend.
You get a report you can hand to your driller, your architect, or the NWRB permit office: depth, indicative yield, saltwater-risk, and a recommended drilling location, with the limits stated honestly. A document you can file and defend.
The sharpshooter
One precise hole, not a field of dry ones.
The old way to find water is to drill and hope, then drill again somewhere else when the first hole comes up dry or salty. That's holes all over your land and money gone with each one. We do it the other way: we read what's under your land without drilling anything, no holes, no excavation, no chemicals, and point the rig at the one spot most likely to work. A sharpshooter, not a shotgun. And because we live and surf here, we'd rather you drill once, responsibly, on a coast where freshwater is already under pressure.
A survey improves the odds and saves the land from trial-and-error holes: it doesn't promise the hole. No survey can.
The economics
A well is a one-way door. You get one shot at the spot.
Drilling a well on Siargao is a major capital decision, and a dry, salty, or low-yield hole is money gone with no refund. A pre-drill survey is a small fraction of the drilling spend, and a fraction of one dry hole. It pays for itself the first time it stops a bad drill.
Exhibit A: Cost of being wrong FIG. 01 · PHP
| Scenario | Cost (PHP) | Outcome |
|---|---|---|
| Blind drill Success (you guessed right) | ₱150k–900k+one well · by size, depth + 20–40% island logistics | Water at usable depth, acceptable yield, no salt. |
| Blind drill Partial fail (low yield / shallow salt) | ₱150k–900k+the same well, then trucked water ~₱2,000–5,000/load, every dry season, for years | Degraded supply for the life of the property. |
| Blind drill Total fail (dry / unusable salt) | ₱300k–1.8M+two wells: you drill again elsewhere (≈ 2× one well) | Two holes; one site eventually works. |
| Recommended Pre-drill survey + targeted drill | A fraction of the drill+ one well, sited on data | One hole, sited on measured data; depth, indicative yield + salt risk known up front. |
Typical Siargao drilling ranges. Depth, access, and rig availability set the exact figure; your driller's quote is the real number. Either way, a well is one-shot: once it's drilled, the spend is gone whether or not it produces.
A survey is a small fraction of the drilling spend, and a fraction of one dry hole.
The no-drill-stake wedge
A survey is only as trustworthy as the incentive behind it.
We don't own a drilling rig. We don't earn a peso whether you drill, where you drill, or how deep. That means our only job is to be right, because an independent read is the kind you can hand to a bank, an owner, an LGU, or a future buyer. When the read on whether and where to drill comes from someone with no stake in the hole getting dug, you can act on it.
We're glad to recommend a good driller when you're ready. We just won't be the ones holding the rig.
The work
What we actually do
We come to your land, take a small number of seismoelectric readings, and interpret them into a written report: the most likely depth to a water-bearing layer, an estimated thickness, an indicative yield range, and a saltwater-intrusion risk read at the time of survey, plus a recommended place to drill.
It's non-invasive: no drilling, no excavation, no chemicals. We arrive, set up, scan, and leave.

Drilling blind, a dowser, a Manila resistivity firm, a one-button detector, or a measured, independent survey on-island.
Most wells on Siargao today are sited by experience, by a dowser, or by a quick detector reading rather than a full geophysical survey. A dowser answers "is there water somewhere here?" A detector flags "the ground is more conductive here." We answer, in writing, "where is it most likely, how deep, how much, and is salt a risk?", and because we don't sell the drill, that read has no agenda. A record you can keep, file, and hand to a driller.
