Mykonos port water system targets 65% restroom demand cut

By Elena Vasquez

In an October 30, 2026 announcement, the Port of Mykonos said it had inaugurated a water-recycling system designed to reduce municipal water demand from public restrooms by more than 65%.

The estimate comes from the project’s technical design, not measured operations. Actual reuse volumes, annual savings and the system’s energy requirements will be monitored once operations begin.

CTL Maritime, part of MSC Group, funded the project in full, and the Municipal Port Fund of Mykonos required no financial contribution. Five Senses Consulting & Development coordinated the initiative; Global Esco handled technical design and installation with the Municipal Port engineering team.

Who conceived the project?

Ioannis Bras, cruise development consultant to the Municipal Port and CEO of Five Senses Consulting & Development, conceived and proposed the initiative and coordinated it from concept through implementation. Bras also serves as a Seatrade Cruise Ports & Destinations Ambassador.

Bras said: “The Mykonos Water Recycling Project demonstrates how our international experience in cruise destination development, combined with extensive expertise in managing complex and innovative projects, can translate local challenges into practical solutions.”

He said recognizing the island’s water-management needs created an opportunity to combine two technologies, targeting annual savings of more than three million liters. He described the consultancy’s approach as destination-specific innovation that produces measurable, lasting benefits for local communities.

How does the system work?

The installation combines wastewater recycling with atmospheric water generation, two technologies intended to reduce reliance on freshwater and municipal water.

• Washbasin water: The system collects used water from washbasins and processes it through filtration, oxygenation and disinfection.
• Toilet flushing: Treated water travels through a separate non-potable network, meaning water not intended for drinking, and is reused exclusively for flushing toilets.
• Atmospheric generation: A second system produces additional water by extracting moisture from the air.
• Performance measurement: A real-time monitoring system records the volume of treated water reused, while a public display shows operating performance.
• Visitor facilities: The project also upgrades restroom equipment, lighting, functionality and hygiene standards.

Is the 65% reduction proven?

The more-than-65% estimate compares the same public facilities operating with and without the recycling system. It remains a projection, while the annual savings target of more than three million liters also awaits operating results.

The Port of Mykonos said savings will be assessed live, including the energy consumed by the installed equipment. Its announcement gives no capital cost, operating cost, water-tariff saving, system capacity, cruise-call volume, passenger count, booking change, revenue effect or commission change. Until operating data appear, the project supports an efficiency target rather than a demonstrated reduction.

What does this mean for cruise sellers?

Mykonos draws significant international visitors during summer, increasing pressure on island infrastructure and water resources, according to the project announcement. Desalination already forms part of the island’s water supply, so lower freshwater demand offers potential environmental and operational benefits.

For cruise sellers, water availability affects the ability of a destination to service calls included in sold itineraries. Reducing municipal demand can therefore strengthen operational resilience, but the announcement provides no cruise arrivals, bookings, revenue or market-share data from which to calculate a commercial gain. It discloses no new distribution channel or commission structure.

Athanasios Kousathanas-Megas, president of the Municipal Port Fund of Mykonos, called infrastructure projects important when they deliver tangible benefits and thanked CTL Maritime and the implementation team. Kyriakos Anastassiadis, senior strategic advisor at CTL Maritime, said the company remained committed to “creating lasting value for destinations and local communities through practical, measurable solutions.”

Once the Mykonos system’s operating performance has been assessed, the project could provide a model for other Mediterranean ports and island destinations facing similar water constraints, the announcement said. The next test is whether monitored reuse volumes, annual savings and energy use validate the more-than-65% target before other destinations consider replication.
