Well Inspection on Koh Samui
A well is the least visible and most expensive-to-fix part of a property. We inspect wells the way a surveyor inspects a building: measured yield, water levels, casing condition and an equipment audit — delivered as a written report you can act on or negotiate with.
Useful to send: what the well is doing and what has changed, plus any records you have. Buying a property? Tell us the date you need the report by.
Who this service is for
- Buyers doing due diligence on a property that comes with a well
- Owners of older wells with no documentation
- Managers taking over a villa with an unknown water system
- Anyone planning upgrades who needs to know what's actually down there
How it fits together
From measurements to a decision
An inspection is only useful if it ends in a decision you can act on.
Measure today's behaviour
Water levels before, during and after pumping, sustained flow, and how the pump draws current.
Compare with records and season
Against whatever drilling or service records exist, and against the time of year.
Find the weak link
Well, pump, controls, wellhead or storage: which one limits the supply, or puts the water at risk.
Report with priorities
Measured findings, photos and what to do first, in plain language.
Your decision
Keep and monitor, repair, rehabilitate, or price it into a purchase.

Common symptoms & problems
Buying blind
A property with an undocumented well is a property with an unknown liability. An inspection prices it.
Yield that declined quietly
Wells lose capacity gradually — clogged screens, dropping water tables. Measurement catches what habit hides.
Contamination paths
Failed surface seals let runoff into the aquifer. Invisible from above, findable in an inspection.
A pump at end-of-life
Pumps rarely announce retirement. Electrical and performance checks estimate remaining life before it fails during high season.

What we check on an existing well
Flow-rate & yield
What the well delivers today — measured, not recalled.
Static & drawdown levels
How the water level behaves under pumping.
Casing & wellhead
Sealing, corrosion and damage checks.
Installed equipment
Pump, controls, tank and wiring — condition and sizing.
Documentation
Whatever drilling or service records exist, reviewed.
Optional water test
Laboratory analysis when the use case calls for it.

What the service includes
Flow-rate & yield test
What the well actually delivers today — measured, not recalled from memory.
Static & drawdown water levels
How the water level behaves under pumping — the health indicator most owners have never seen.
Casing & wellhead condition
Sealing, corrosion and damage checks on the parts that protect the aquifer.
Equipment audit
Pump, controls, tank and wiring reviewed for condition, sizing and safety.
Optional laboratory water test
Water quality analysis when the use case calls for it.
Written report
Findings, photos and prioritised recommendations — in plain language.
How it works
Document review
Whatever records exist — drilling logs, invoices, previous repairs. Partial is fine; none is common.
On-site testing
Yield, water levels and wellhead condition measured at the property.
Equipment audit
The installed pump, controls and storage assessed against the well's measurements.
Report & walkthrough
You get the written report and a conversation about what it means — and what it doesn't.

Important technical considerations
- Measurements are a snapshot; yield can vary with the season and over the years.
- Some casing and downhole issues can't be seen directly and are inferred from behaviour.
- An inspection reports condition and risk — it is not a guarantee of future performance.
- Equipment age and installation quality weigh as heavily as the well itself.
- Every well is different, especially older or undocumented ones.
Service · Koh Samui
What affects cost & timeline
- Well depth and site access.
- Whether a laboratory water test is added.
- The scope and turnaround of the written report.
Site conditions vary from plot to plot, so we quote a fixed, itemised price after the site assessment — never a fixed figure beforehand.
Before you decide
Guides from the field
If you are buying a property with a well, or yours has started behaving differently, these help you read what an inspection finds.
Frequently asked questions
How long does an inspection take?
Usually a few hours on site, depending on well depth and access; the written report follows within days. We confirm scheduling when you book.
Can you inspect a well you didn't drill?
Yes — most wells we inspect were built by others, often with no surviving records. The inspection is designed exactly for that situation.
Does the inspection include water quality?
Yield and construction are standard; laboratory water analysis is an optional add-on we recommend when the water is used for drinking or the property will host guests.
What happens if you find problems?
The report lists findings with prioritised recommendations and realistic options. What you do with it — repair, renegotiate a purchase, or monitor — is your call, with no obligation to us.
Can an inspection tell me how the well will behave in the dry season?
It measures how the well behaves on the day and compares that with the season and any older records, which is usually enough to say whether the dry months will be tight. A well tested at the end of the rains will look better than it does in April; the report says so and, where it matters, we recommend a second measurement in the dry season.
What should I check before buying a villa with a well?
Ask for the drilling and service records, then have the well measured rather than described: water levels, sustained flow, the pump's condition and current, the wellhead and, if the water is drunk, a laboratory test. Findings that need money spent are easier to agree on before signing than after.
Tell us what the well is doing
What has changed, how old the system is if you know, and any records you have. Buying a property? Tell us your deadline and we plan the inspection and the report around it.
