Water Conservation
CLIA-member cruise lines employ advanced water conservation and onboard freshwater production systems, with most ships capable of producing all or nearly all of their own freshwater needs.

CLIA Cruise Lines Lead in Advanced Water Conservation and Onboard Freshwater Production
In addition to implementing superior water treatment practices, CLIA-member cruise lines employ advanced water conservation techniques and sophisticated onboard freshwater production systems. The majority of CLIA members generate their own fresh water directly onboard, reducing reliance on external sources in water-scarce regions, with many ships capable of producing enough freshwater to meet their total consumption needs.
Ships
267
The number of ships that produce their own fresh water onboard their ships. Representing more than 94% of reporting ships and 96% of global capacity
Percentage
90%
Percentage of cruise lines that enable state-of-the art systems to produce water on board rather than draw from areas where resources are limited
Ships
172
The number of ships able to produce water equivalent to their total water consumption needs, which represents 60% of the fleet
Innovative Environmental Practices: How Cruise Lines Enhance Sustainability through Advanced Water Management
This is made possible by a range of environmental practices – a few examples include:
- Irrigation systems on private islands that repurpose treated wastewater to maintain landscaping and other features.
- Steam evaporation using the heat from ship engines to condense desalinated water into distilled purified water.
- Reverse osmosis that purifies water using semi-permeable membrane filters to separate water and salts.
- Aeration to reduce the amount of water need to provide guests comfortable water pressure in showers and sinks.
- Re-purposing and re-using water such as using condensation methods to collect water produced by HVAC systems for re-use in laundry systems.
