The world's largest cruise ship conserves water better than America

The average American uses about 80-100 gallons of water each day, according to the USGS. How does that compare to someone aboard a cruise ship that can carry more than 8,000 people, like Royal Caribbean’s Symphony of the Seas?

“We’re averaging about 50 gallons per day [per person]. And that includes everything. That includes the technical water, the laundry water, [and] the galley water.”

That means at full capacity of 8,880, including guests and crew, a ship like Symphony of the Seas can produce about 444,000 gallons of wastewater per day.

“They are modern day wastewater treatment systems that you would see on land,” Rose said as he explained the process for treating wastewater on Symphony of the Seas.

In the video above, we walk through the process of how the world’s largest cruise ship conserves water.
