DEEP WELL SAMUI

Water Filtration Systems on Koh Samui

For well owners on Koh Samui, Koh Phangan and Koh Tao with mineral or quality issues, families asking whether the water is safe, and hotels with guest-facing standards. Island groundwater varies bore to bore, so we test your water first — well or delivered — then size the system to what the results actually show, never to a problem you don't have.

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:

  • Water analysis — what the test actually finds
  • Required output — a kitchen tap and a resort kitchen are different systems
  • Existing infrastructure — pump pressure and pipe condition

Filtration system installed

Priced per site — free survey & written quote.

Testing first is the rule — we don't sell systems for problems your water doesn't have.

What's included

  • Water quality assessment
  • System sized to your test results
  • Installation and commissioning

Priced separately

  • Ongoing cartridge replacement (service plan available)

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

  • Water sampling and lab-grade testing
  • Plain-language explanation of results
  • System recommendation matched to use
  • Installation and commissioning
  • Service schedule for cartridges and media

How it works

  1. Test

    We sample your well or delivered water and test it. Island groundwater commonly shows hardness, iron and manganese — but we treat what's found, not what's assumed.

  2. Recommend

    You get the results explained in plain language, with options by use: general household, drinking water, or hotel-grade.

  3. Install

    The system is installed, flushed and commissioned, with the pump checked for pressure.

  4. Service

    Cartridges and media have a service cadence. We schedule it — or show you how to do it yourself.
