Wärtsilä Water & Waste has a 58-year STP track-record with merchant vessels. Since 1963 our Super Trident® sewage treatment plants (STPs) have been widely regarded as standard specification for all vessel types.

As Wärtsilä Water & Waste we have a 58-year STP track-record with merchant vessels. Since 1963 our Super Trident® sewage treatment plants (STPs) have been widely regarded as standard specification for all vessel types, including merchant ships. Over 12.500 of our STPs have been installed on ships around the world, making it the largest installed base of sewage treatment plants in the marine industry. Total number of merchant ships equipped with our sewage solutions: around 1800!

In particular containerships - currently the fastest growing segment in the marine sector – reap great benefits from this solution: it enables them to sail for weeks without the need of entering a port for waste disposal, while staying fully compliant with International Maritime Organization & U.S. Coast Guard regulations.

Our most popular STP model for merchant vessels is the STC02-13. It represents 28% of all Super Trident® sewage treatment plants installed onboard.
