Water?


Recommended Posts

I forgot to add "the exception does not disprove the rule". No matter how many people say it worked, it's still against the rules. The method you use to get in on board doesn't matter. In the end worst case scenario is your water will be confiscated or you'll have to make a trip to the naughty room. Hardly a CRM and they don't kick people off the ship for it.

The yellow to brown cloudiness sometimes found in ship's water is caused by maintenance of the piping system. Due to the requirement for residual chlorine in the water, this chlorine tends to form a thin scale layer on the inside of the piping. As long as the water fills the pipes, and continues to flow (the water on the ship is in continual recirculation, unlike municipal supplies), this scale stays where it is, and has no effect on the water. When the system is shut off in a section, and the pipes drained for repair, the scale dries out and falls off the pipe walls. When the system is placed back in service, the scale particles get circulated around and tend to find the places where the water is still, which are the short branch lines going to each sink and shower, and will collect there. When the sink tap is turned on, this cloudy water comes out, but typically will clear after a minute or so of running the water.

 

The highest concentration of any minerals in ship's water comes if the ship loads water in port, as this will be the local municipal water, and will have that municipality's "hardness". Otherwise, the water is distilled from seawater, and since this is boiled water that is condensed back into water, there are no minerals, salts, or anything in it. Also, water is made by reverse osmosis, where the water is forced through a porous membrane, and the pore size only allows things the size of or smaller than a water molecule to pass. Most mineral salts that are present in water are larger than the water molecule itself, and cannot pass.

 

There are only two things allowed in the drinking water on ships: chlorine (sodium hypocloride) and calcium carbonate (the antacid ingredient in Tums) used to control pH.

 

As for the toilet water, it is exactly the same fresh water as used everywhere else on the ship. The water supply for the toilet branches right off the water supply to the sink and shower, just like it does in your home.

 

Very informative post from someone who knows. Can I assume from your avatar that you are a USMMA. graduate.

Does Royal Caribbean allow its passengers

to bring on bottled water?:confused:

 

As mentioned...not allowed, but not really enforced.

 

I love my Dasani...dislike the ship's offering of bottled water. The water from the tap is much better IMHO.

 

Do yourself and the hard working porters a favor and put your bottled water in a duffel bag with handles, like I do. Those cases that pax "just slap a tag on" are very hard to handle, and are most often refused at check in with your luggage at Port Canaveral in fact. My 10-12 bottles of Dasani always find their way to my cabin in that duffel with a luggage tag on it. No problem.

 

Later you can just fold that duffel bag and put in your luggage at disembarkation day.
