Water
The good thing is, that we are only minimally dependent on shore-sourced (bunkered) freshwater. The water we consume for showers, food preparation and our pools, for example, comes from the ocean. Thanks to our ship´s own seawater desalination plants that work with reverse osmosis, we can treat salty water directly on board and then enjoy it as freshwater and drinking water on the cruise.
How it works:

This not only makes us self-sufficient but also conserves water resources in destinations where water is scarce. However, since the desalination plant also consumes energy, we use water sparingly. We implement this in many ways, for example, with infrared faucets in public restrooms, vacuum toilet systems, and on-demand bed linen and towel changes.
Purified wastewater flows into the ocean
Of course, no untreated wastewater is discharged at sea. Instead, we collect it on board and clean it thoroughly in our Advanced Wastewater Purification (AWP) system. These modern plants are comparable to onshore sewage treatment plants and treat all wastewater in a multi-stage process, finalizing with UV disinfection. This results in treated wastewater which we discharge ashore when in port, or into the ocean as long as the ship is outside the of the three nautical mile zone.
