Yacht Water Treatment in Mallorca

Fast Response

Mallorca’s vibrant yachting industry presents unique challenges when it comes to onboard water quality.

With high calcium content in local water and busy shipyards like STP and Astilleros de Mallorca hosting hundreds of refits each year, timing is critical.
At Octo Marine, we provide fast-response, regulation-ready water treatment services across the island — including Palma, Port Adriano, Alcúdia, and beyond.

  • RO System Commissioning & Maintenance

Ideal Timing: Palma Refit Season

The winter and early spring yard period is the best time to:
  • Disinfect tanks and pipework while systems are open
  • Upgrade point-of-use filters
  • Train crew on system hygiene protocols
  • Complete regulatory water testing before launch

Our technicians regularly coordinate work around other contractors to minimise downtime and ensure your yacht is ready on schedule.
