Deep Well Drilling in Koh Samui & Koh Phangan
For villa owners, landowners and developers who want a water supply that doesn't depend on the municipal grid. We survey your site, drill and case the well, and hand over a tested, working water source.
Transparent pricing
Honest starting prices — and a fixed written quote before any work begins.
What determines your price
No two sites on the islands are the same. Your final price depends on:
- Depth to water — the single biggest cost driver; it varies street to street
- Soil and rock conditions — granite layers drill slower and need different tooling
- Site access — narrow roads, steep hills and soft ground limit what the rig can reach
- Casing specification — sized to your daily water demand
Typical villa well
Priced per site — free survey & written quote.

- Well development and flow test
Priced separately
- Pump and tank system (priced separately)
- Electrical works
Final fixed price confirmed after a free site survey.
Final price depends on site inspection, distance, access, depth, soil/rock conditions, equipment, required materials, water volume, and urgency.
You'll get a written fixed quote after the survey — the price we quote is the price you pay.
What's included
- Site survey and drilling-point selection
- Drilling to the water-bearing layer
- PVC or steel casing with sanitary sealing
- Well development (airlifting) until the water runs clear
- Flow-rate and recovery testing
- Written handover report with depth and yield figures
How it works
Site survey
We assess geology, access and your daily water demand, agree the drilling point, and give you a fixed written quote before anything else happens.
Drilling
The rig drills to the water-bearing layer. On most Samui sites that's 40–120 m; the survey tells us what to expect before we start.
Casing & sealing
The bore is cased and sanitary-sealed so surface water can't contaminate the well — the step that decides whether a well lasts decades or years.
Testing & handover
We develop the well, test flow and recovery, and hand over a written report. If you want pumps, storage or filtration, we design that next.
