The water system is one of the few parts of a build that's far cheaper to plan early than to retrofit. Decided late, it becomes trenches through finished landscaping and a pump squeezed into whatever space is left. Decided early, it's just another line on the drawings.
Start with real demand
Everything sizes from how much water the finished property will actually use — occupants, bathrooms, a pool, irrigation. For a villa or small resort that's a calculation, not a guess, and it drives every decision after it. We show the maths rather than hand over a number.
Then work through the chain
- Source — a well, a delivery-fed setup, or both, depending on the plot and the island
- Storage — sized to the demand and the local resupply reality (bigger on Phangan and Koh Tao)
- Pressure — pumps and controls that hold steady pressure across the whole property
- Treatment — filtration sized to a water test, planned in rather than added later
Coordinate, don't retrofit
The water plan works best in the hands of your architect or project manager, with specs and drawings they can build to and the drilling, tanks, pumps and filtration installed in the right order for the schedule. On the islands, where a rig may cross by ferry, that sequencing is a planning detail worth getting on the calendar early.
Common questions
When in the build should we start? At the design stage, alongside the architect — the source and storage decisions affect where things physically go, so the earlier they're fixed, the cheaper they are.
Can you work with our contractor? Yes — the point of a system design is that it slots into your project plan with specs and documentation your team can build to and hand over cleanly.
