Borehole Drilling & Installation on Koh Samui
For construction firms, developers and owners with a drilled hole that was never finished. We complete boreholes properly: casing, wellhead, sanitary sealing and yield testing.
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:
- Bore depth and condition — completing an existing hole starts with an inspection
- Casing specification — material and diameter sized to the well
- Site access — equipment reach at the wellhead
Complete borehole installation
Priced per site — free survey & written quote.
We also inspect and complete boreholes drilled by others.
What's included
- Casing and wellhead completion
- Sanitary sealing against surface contamination
- Yield and recovery testing
Priced separately
- Drilling of a new bore (see deep well drilling)
- Pump system
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
- Condition inspection (for existing bores)
- Casing supply and installation
- Wellhead completion with a clean concrete pad
- Sanitary sealing
- Yield testing with a written report
How it works
Inspection
For an existing bore we run a condition and depth check first — you get an honest verdict on whether it's worth completing.
Casing
The bore is cased to spec. Casing is what separates a borehole that lasts twenty years from one that silts up in two.
Sealing & wellhead
Sanitary sealing keeps surface runoff out of your groundwater; the wellhead is finished with a tidy pad, ready for a pump.
Yield testing
We measure flow and recovery and document both, so any pump installer — us or anyone else — can size equipment correctly.
