Q: Should I bring water purification tablets for my trip to the Yangtze River?

A:

Yes, bring them as a lightweight backup for onshore excursions, but you won't need them for the cruise ship's water. The vessel's potable water is treated, stored in sanitized tanks, and is safe for drinking and brushing teeth. Municipal supplies at ports are also generally treated.

From a sanitation pro's view, a modern cruise ship is a closed-loop system. The drinking water is either produced onboard via reverse osmosis or loaded from verified municipal dockside sources into disinfected holding tanks. Chlorine or UV residual maintains safety in the pipes. It's a controlled, monitored system unlike an open river source.

Pack the tablets for extended land tours to remote areas. On the ship, use the cabin's provided bottled water or fill your bottle from the dining room dispensers. Ashore at standard tourist ports, sealed bottled water is the simpler, more reliable choice. The tablets are your mechanical insurance for unexpected situations outside the ship's engineered environment.
