Unlike feces, pee is generally sterile*, so basically it's just water with some organic compounds. In that sense it's actually cleaner for the environment than bath water, which contains lots of artificial chemicals, surfactants in particular. Edit: okay since people seem to have a problem with me saying "pee is generally sterile", let me clarify: I'm not recommending you use pee as disinfectant, and in fact I am most likely technically incorrect. I am saying that in the context of waste water treatment, pee is not very harmful to the environment when compared to bath water. There are billions of Fish in the oceans that pee all the time. But fish don't use shampoo, at least as far as we know.

Great video! I'd like to point out that according to MARPOL Annex IV, the discharge of untreated sewage is allowed beyond 12 nmi from the nearest land outside of special areas (Baltic Sea for passenger ships). In theory this means that a passenger ship crossing the Atlantic can discharge raw untreated sewage directly to the sea at a moderate rate. Cargo ships can discharge raw sewage even in the Baltic with the 12 nmi rule. There are also problems with sewage treatment plants as recent studies indicate that in many cases they do not function as they should due to technical or operational reasons. This means that there are cases where raw sewage is discharged right in front of our beaches. The discussions regarding this issue are ongoing at the IMO.

The Olympic Class liners I'm sure just dumped it overboard, no treatment at all. Back then there weren't really any regulations on such.

Where does the water come from? A huge tank filled at the port or do they purify sea-water during the cruise?

[@CasualNavigation]

Both actually. Big storage tanks, which can be filled from the shore, but they also use waste heat from the engines to make fresh water all the time the ship is running too.

[@themusicalpilot1382]

Modern vessels usually have an onboard desalination plant where they can take in sea water, and remove salt and other contaminates to make it same for consumption it use in toilets, showers, sinks, etc

[@runarandersen878]

I also would have guessed they use sea water. Instead of carrying huge amount of water. I also guess for some small islands, using their water to fill a large cruise ship would not be good because of the amount.

[@Danieloncarevic]

Mostly sea water itself. Then using something like "reverse osmosis" which basically removes the salt, to put it the simplest way possible. That being said, when vessels spend more time in port or shallow anchorages it's not possible to get sea water so some reserve must be on board, depending on the size of the vessel and the demand. It's not rare that vessels take fresh water from the shore, depending on the area they are trading and the effectiveness of their water treatment facilities on board.

This is exactly what I used to design. I used to be the process engineer for Wartsila. What you described was a standard sewage treatment plant, where most tankers, cargo vessels and old cruise liners have. The newer cruise liners usually use a more advanced type using MBR or MBBR technology due to the more stringent IMO 227.64 including section 4.2. I'd be happy to explain further if you're interested.

[@Rebasepoiss]

Do ferries just use regular storage tanks and then empty them at the harbours? I'm talking about ferries that do relatively short journeys, up to 20 hours, let's say. I'm interested in this because I live in Tallinn which has a very busy harbour at around 10 milion passengerys annually, most of them travel between Tallinn and Helsinki, some between Tallinn and Stockholm. The rest (approx half a million) are cruise tourists.

[@StrongAsHouses]

@@Rebasepoiss It depends on a lot of variables including space, the amount of water that is required to be stored and how much the ports charge to accept the wastewater. For those sort of ferries it would easiest to just store the water until they get to the port. However after a cost analysis it might be more financially viable to put a simple sewage treatment plant on.

[@seraphina985]

@@StrongAsHouses Still can't imagine it should be all that expensive I would expect the bulk of the cost for it would simply be compensating the port for their sewage bill along with a small fee to oversee the transfer process since I presume that is probably what most ports do is just dump it into the municipal wastewater system of the nearby city.

Hmm.. the ship does not treat gray water much because it could kill off the good bacteria, so it just discharges it into the ocean? Rather insane.

This methane is then used to fuel generators to produce 'green' electricity. If you're interested in learning more about it. Do a search for 'wastewater cogeneration'. At my plant we process an average 7 MGD (million gallons per day) everyday. Like in the video, the water being discharged is often cleaner than the body of water it's going into. We are able to show this by sampling above and below our discharge point in the river. If you can, I recommend taking a tour through your local treatment facility. There are a number of different ways that they operate. Often, it's determined by the scale of the operation. Not to mention, it's always good to see what you are paying for.

I enjoyed this a lot

[@roberttucker1527]

Same, good to know that ships aren't that dirty

[@geoffreykitson532]

Great job on this video very well spoken, I’ve wondered for years what happened to human waste on ships. Well done.

[@Seamus322]

Every so often, you hear about a ship getting caught with a "magic valve"- dumping waste directly to the sea.....

[@endraruhendri6550]

Some does have but most don't

[@Seamus322]

@@endraruhendri6550 - The fines are too steep and people lose their licenses when caught.

[@relighg]

Thanks for this info. I just watched a news about cruise ships and got me thinking of this

[@TheRoneZone]

Word on the street is, they put stuff in the food (stool softener) to prevent wear and tear on the pipes. But you didn't hear it from me (cruise ship musician with 9 years experience) haha.

[@johnkirk.]

where does the solid sewage go after treatment and filtration?

[@Daedric16]

After the bacteria are done with it, it essentially resembles soil, and gets sent to landfills. Similar process for municipal water treatment plants.

[@johnkirk.]

@@Daedric16 ah ok, interesting. do you think there's any possibility it could be used as manure? would it still contain nutrients?

[@Flakpanther]

@@johnkirk. Yes but 1. There really isn't a lot of demand for manure in industrialized countries. Think about how much factory farmed meat for example creates, and in that case you know exactly what's in it. In any case it's more common to synthesize nitrates and mine phosphates and potassium in industrial farming. 2. You don't know what's in this stuff necessarily. Pharmaceutical residues and microplastics, for example. NYC tried selling off their sewage solids in the early 2000s and the company contracted to do it went bust because of a lack of market and difficulty of quality control

[@johnkirk.]

​@@Flakpanther wow super interesting. Apparently it is something that happens in poorer countries though. NYC trying to sell off leftover shit is wild lol. Please tell me more/link me to something good about that

In the old days we just stuck our bum out of a port-hole!

[@mikekelley4181]

People on vacation probably drop tons of 2's and huge ones too considering all that food that's available.

[@felipebetioli4391]

I LOVE THIS CHANNEL!!!

[@BangMaster96]

Thumbs up if you've ever been on a cruise ship! I've been on a cruise ship once, it was the Carnival Cruise ship that went from Long Beach to Baja California.

[@BangMaster96]

@Harvey Logan Mine was Ensenada as well, it is in Baja California.

[@Mike_B.]

Nice vid mate, and cool info. Looking forward that in the future you can explain to us how the Boeing Jetfoil works. That is when you have time. Anyways, I'll be waiting. and again, cool vid...

[@CasualNavigation]

Cheers Mike - I already have it on my list.

[@shantolion1576]

I wonder what happens to all the hummm waste 😵💩💩on the plane

[@christopherbonanno1120]

Instructions not clear took a cruise and I forgot to poop now I’m being SHIPED off to the hospital 😂

[@oooooo-kr4ep]

Hahahaha

[@rip9597]

Not funny didn’t laugh

[@christopherbonanno1120]

R Ip well that is unfortunate

[@joshuahalla.k.a.controlla6333]

Great video. ☺️

[@iyataitt2684]

Great vid man! I love learning about underlying mechanisms, processes, and systems.

[@GarfieldRex]

Nice vídeo, thanks for enlighten us 😌. Got a question, Where do the ships store all drinking and other use water? Can they filter sea water for the entire ship?

[@CasualNavigation]

They have large tanks, but are always taking it on when they can and making it from sea water

[@GarfieldRex]

@@CasualNavigation Thank you very much for answering 😁👌😌

[@zman90]

I never thought Poop in cruise ships was so interesting

[@MrHansDelbruck]

Bacteria: So Jerry, what's on the drink menu for tonight? Jerry (Bacteria): Oh, ya' know... The liquid extractions from poop.

[@sailorman9595]

All ships have an FW generators which A unit used for conversion of seawater into fresh water by vacuum distillation based on evaporation and condensation. Single-stage freshwater generator consists of a chamber with two titanium plate packs acting as an evaporator and a condenser respectively. A vacuum of 85-95% is maintained in the system by a brine/air ejector. Seawater evaporates at a temperature of approximately 40°C due to the vacuum condition as it passes between the plates of evaporator heated by hot fresh water from the engine jacket cooling system, or by steam. Generators can be equipped with disinfection units (Chlorination, UV-radiation and Silver ionization), pH-adjustment and rehardening filters.

this channel is the reason I don’t sleep

Urgent question. So, if one shat in the shower and put the shampoo in the toilet, how much havoc could one create?

Shout out from Glastonbury! That’s caught me by surprise 😂😂😂
