SPARKY12 Posted January 14, 2008 #1 Share Posted January 14, 2008 What is going on with sewer smells in ships? Just got off the Valor and we smelled it almost daily in our room, the hallway and at the tables by the pool, It would come and go. It can't be too healthy to be smelling this all week. It's gross, enough to make you not want to cruise. A few days we woke up to that smell. I complained to the purser's desk and they acted like they never heard of it. but other passengers complained about it also. I have cruised since the 70's and have never heard of this. I did a search on google for sewer smell and passengers on the Holiday, Glory, Triumph and the Caribbean Princess have smelled it also. Link to comment Share on other sites More sharing options...
Kan't Wait Posted January 14, 2008 #2 Share Posted January 14, 2008 If you don't want sewage smell stay away from Celebrity Millennium as well. I won't sail her again. I sailed Summit and didn't smell any sewage. Not sure what is going on. :confused: Link to comment Share on other sites More sharing options...

And.... for the purser's desk to act like you were the first to complain..... they were just stiffing you. I would expect the cruise line to try and rectify the situation..... because word spreads fast. ;) Link to comment Share on other sites More sharing options...
Lowie Posted January 15, 2008 #4 Share Posted January 15, 2008 chasetf, word isn't spreading fast enough. i read about the sewer smell on the carnival triumph on these boards well over a year ago and then dealt with it first hand on our cruise last june. carnival knows very well that there is a problem. may be caused by people flushing things they shouldn't be flushing, but either way it needs to be fixed. on our cruise, the carpet in the hallway outside of out cabin was wet and stinky beyond belief. when we first complained, right after boarding we were told that it was Miami that was stinky!! if i had the money, i would have taken a sample and sent it off to a lab. i do, however, have pictures of the wet/stained carpet. worst part was all the people walking in bare feet! YUCK! Link to comment Share on other sites More sharing options...

BruceMuzz Posted January 16, 2008 #6 Share Posted January 16, 2008 There are several causes for sewage smells on cruise ships today. The primary one is the new state of the art sewage treatment plants that most cruise ships have today. The only by-product that goes into the sea is drinking-quality water. The waste solids are burned, leaving only ashes. But an additional by-product is an awful sewer smell. Ideally, the odor is vented to the top of the smoke stack, where the wind blows it away. But too many new ships have discovered pin holes and cracks in the vent piping. Even the tiniest holes or cracks can cause dreadful odors to permeate the ship. It is not dangerous, but very annoying. Another annoying odor causer is the drain in your bathroom floor. Instead of an odor trap like your drains at home, ships have a scupper with a small metal dome inside. If the ship rolls a bit the water barrier in the scupper is broken and the sewer gases from the grey water tanks below are allowed to escape into your cabin. Contrary to popular belief, grey water smells are far worse than sewage smells. Pouring additional water into the floor drain of your cabin usually solves the problem. Despite endless warnings about what can and cannot be flushed down a vacuum toilet, many passengers just don't get it. They treat the toilet like a garbage disposal. Once it stops up, sewage and smells escape along corridors and into cabins until the engineers can correct the problem. On a large ship this typically occurs 20 or more times per day, all over the ship. A single toilet stoppage can have negative effects on as many as 60 additional cabins. Norwalk Virus has an additional by-product; bad odors. The two most popular chemical bleaches that are sprayed, fogged, and wiped everywhere to combat the virus have very annoying smells. Virkon smells almost exactly like urine. Virox smells remarkably like vomit. During NLV outbreaks ,we mix these bleaches to a stronger concentration, giving them even stronger odors. When you first board a ship, the chances are very good that the thorough cleaning just completed will result in some annoying odors. 1 Link to comment Share on other sites More sharing options...
cb at sea Posted January 16, 2008 #7 Share Posted January 16, 2008 Those are annoying odors--you'd think an engineer somewhere could figure a better way to stop them! We had this problem on every ship we've sailed--some worse than others. Design flaw! Link to comment Share on other sites More sharing options...

drdrd Posted February 2, 2008 #11 Share Posted February 2, 2008 Went on Mariner of the Seas twice last year. One cabin was fine, the other had the smells periodically but only in the bathroom.

4x4bob Posted February 2, 2008 #12 Share Posted February 2, 2008 Wonder if taking a flat round rubber drain cover would help with this problem? (Add this to: duct tape, electrical cord, lysol spray, crockpot, blender, ear plugs, etc, etc. :D ) Bob 1 Link to comment Share on other sites More sharing options...
cb at sea Posted February 2, 2008 #13 Share Posted February 2, 2008 We've found that running water, and then closing the drain stoppers helps--but doesn't stop it entirely. This is a design flaw that needs to be addressed. This has happened on EVERY cruise we've been on--sometimes only for a little bit, sometimes for days. It's annoying and sickening! Engineers!!!! HELP!!!!!!!!!!!!!!!!!!!!!!! Link to comment Share on other sites More sharing options...
bencal Posted February 2, 2008 #14 Share Posted February 2, 2008 We had a sewage smell coming up from our bathroom sink on Mariner 2/05. It was most noticable in the early morning late evening and when we complained they acted like they had no idea what we were talking about. 11/06 I was on a Danube River cruise the hallway and our room stunk like sewage. Again, they did not smell it and said it was probably the river. RIGHT!!! They gave us a Glade Plug In for our cabin and put them in the hallway too which only made it worse, now we had floral flavored sewage. By the end of the week all our clothing smelled just like the boat. YUK!! I forgot to mention we had the most $$$ cabins on the boat. Link to comment Share on other sites More sharing options...
DonMar Posted February 2, 2008 #15 Share Posted February 2, 2008 From BruceMuzz: "Another annoying odor causer is the drain in your bathroom floor.

I worked on a ship turned museum and we had the sewer smell a lot in our offices (since we all had original ship "heads" as part of our offices). While we did not roll causing the water in the trap - or as BruceMuzz says scupper - of the floor drain to disappear, it did evaporate over time. We simply would pour a small bucket of water down the floor drain each week and no more smell. Link to comment Share on other sites More sharing options...
JoshGrrrr Posted February 3, 2008 #16 Share Posted February 3, 2008 When you put thousands of people on something the size of a cruise ship, then feed them all they can eat, I'd expect sewage to be a problem. Think of all the food that gets eaten. We all know what it turns into. Nasty. I get annoyed when I smell a sewage smell on a cruise ship, but I'm pretty forgiving about it. Things can't work perfectly all the time. With that much sewage to deal with it doesn't seem like it would take much of a hiccup in the system for the smell to go where it shouldn't.

port authority69 Posted May 25, 2017 #18 Share Posted May 25, 2017 My wife and I have encountered the sewage smell on all of our cruises. My solution was to put a wet wash cloth over the shower drain..........Voila! It is apparent that they do not have a conventional trap in the shower drain to in order to minimize the required space between decks. 1 Link to comment Share on other sites More sharing options...
Kartgv Posted May 25, 2017 #19 Share Posted May 25, 2017 We also have experienced foul odors on most of our cruises on Celebrity, RCI, and Princess. Most were sporadic. We learned here on CC to take one of the small, flat round rubber drain covers and it does stop the odor from coming up from the floor drain. It doesn't help, however, the smells that sometimes permeate hallways in some areas. It would be great if the cruise ship designers could solve this problem, but we're not holding our breath! :D Link to comment Share on other sites More sharing options...
chengkp75 Posted May 25, 2017 #20 Share Posted May 25, 2017 My wife and I have encountered the sewage smell on all of our cruises. My solution was to put a wet wash cloth over the shower drain..........Voila! It is apparent that they do not have a conventional trap in the shower drain to in order to minimize the required space between decks. In fact, they do have a trap in the shower drain, but it is an "inverted bucket" type, not a "P-trap" or "barrel trap" like you have at home. More likely the cause was the bathroom floor drain trap drying out. This is a separate drain from the shower, and is usually a round drain tucked under the toilet, or a trough drain at the bathroom door. A glass of water down these traps daily will replenish the water evaporated by the dry A/C air. We also have experienced foul odors on most of our cruises on Celebrity, RCI, and Princess. Most were sporadic. We learned here on CC to take one of the small, flat round rubber drain covers and it does stop the odor from coming up from the floor drain. It doesn't help, however, the smells that sometimes permeate hallways in some areas. It would be great if the cruise ship designers could solve this problem, but we're not holding our breath! :D As noted above, a glass of water down the drain works as well, and saves you from bringing a drain cover. The smells you experience around the ship are from the same problem that happens in your cabin's bathroom, the floor drain traps dry out. These drains are in places like the service pantries (where the stewards get their ice and wash the glasses), the lockers where they store the linen carts, and various "technical lockers" or pipe run spaces where the drains see little or no water on a regular basis, but have to have drains for accidents, and so the traps dry out. Usually, once the crew smells this, they will refill the traps and the smell goes away for a couple of weeks. Link to comment Share on other sites More sharing options...

chengkp75 Posted November 1, 2017 #24 Share Posted November 1, 2017 -- THANKS TO THE EXPLANATION! My question is: Do the above 3 "causes of odors" also apply to RIVER BOATS? The causes of odors are common between ships and river boats. I will disagree with Brucemuzz about blocked toilets causing smells. Since the toilet system operates on a vacuum, it is a completely closed system, unlike toilets on land that require a vent to operate. Blocked toilets would cause no smell other than at the bowls that are filled with "product" that cannot be flushed. Only when the engineers open the piping system to clear the blockage would any odor escape, and only while they have the lines open. I would also dispute his statement of 20 blockages per day. 2-3 per day is far more common. By far the most common source of "sewer odors" is a dry drain trap.
