Separett Waterless Toilet from Sweden

Separett Waterless Toilet

Urine separating toilets like the Separett represent the first true advance in this technology in many years.

Composting toilets have been slow to catch on, because of problems with odor.

This has largely resulted from too much liquid mixed with solids. With too much moisture you don’t get compost – you get a stinking mass of raw sewage! By separating the urine from the solids these toilets solve this problem – resulting in odor free, trouble free composting. Separett composting toilets are only now becoming widely known in North America, although they have been used and proven in Europe for over 10 years.

Here is how the Separett works:

Urine is separated in the bowl. There is a drain in the forward section. Urine will naturally flow into this drain when we sit on the toilet. If standing, you may need to aim slightly forward. Standing may result in splatter, therefore the manufacturer recommends men sit down. The blue ‘trap door’ or ‘view screen’ seen in the toilet bowl on the right opens automatically when you sit down. The solid material drops down into the lower compartment, where it rapidly dries out and shrinks dramatically.

 

The urine drains away from the Separett toilet and is then disposed of in one of 3 ways. Urine is virtually sterile and does not pose a health risk.

Soilds are contained in a lower bin, lined with a compostable plastic bag. The solids rapidly dry out, with the aid of a fan. This is critical to the success of the Separett, because the focus is dehydrating the material. To be blunt, dried poop does not stink. Because the material is shrinking rapidly, this bin will only need to be emptied about once a month or so, depending on the number of users. 2 bins (and 2 lids) are included with the toilet. Solid waste never comes in contact with the inside of the Separett toilet. It is all contained in the compostable bag. This makes emptying the Separett clean, fast and easy. You simply open the toilet, close the plastic bag, and take it outside to finish composting in a compost bin.

Ventilation

venting optionsA big advantage of the Separett composting toilet is that you have several venting options. Many other composting toilets MUST be vented through the roof only, because of odor issues. The Separett operates virtually odor free, so direct venting through the wall is also possible. All composting toilets should be ventilated. If they are not, any smell will have nowhere to go other than into the dwelling. A small fan (built into the Separett) is the best way to do this. If there is no power available, you can try a passive vent that rotates in the wind. If at all possible, I strongly recommend using the fan. You can use a deep cycle (RV or marine) 12 volt battery, and a small, inexpensive solar panel to charge it. That is all the power you need. I do understand that some people have very remote cabins, and don’t want the hassle of electricity.

Below you can see an outdoor Separett installation, with no power and a rotating vent.

 

This might be fine in an out building. In your house, you’ll need the fan to eliminate any chance of odor. There are two Separett composting toilet models, and the only difference is the fan. The Separett 9200 AC uses regular household electricity. You just plug it into a wall outlet.

The two speed 9200 AC fan runs on 18 watts on high, 14 watts on low. The 9210 DC runs on 12 volt electricity. This is perfect for off the grid situations or anywhere power consumption must be minimized. The one speed 9210 DC fan uses about 3 watts. The Separett 9210 DC does come with a wall adapter, so you have the option of plugging it into a regular outlet if you wish. Both fans are very quiet, slightly louder than a whisper. The 9210 fan noise is rated as less than 30db, and the 9200 two speed fan is 31/41 db.

The fans move a lot of air. The 9210 is 25 cubic meters per hour. The 9200 on low moves 35 cubic meters per hour, and on high it is 45 cubic meters per hour.

The #1 question is….”How do you clean it?” The opening for the solid waste is large, and the sides are almost vertical. So there is less mess than you might think. Keep a spray bottle with water and vinegar by the toilet. After use, spray the bowl. Then wipe it clean with a paper towel. Drop the towel into the waste compartment.

The dimensions of the Separett are as follows. These diagrams are in metric (sorry!).

Typical Customer Feedback on the Separett. Zero unsatisfied customers to date.

“I did a lot of research when looking for a composting toilet for the new rental house I was building on my property. I decided upon the Separett 9200 Villa that separates liquid waste from solid waste. It seemed to make sense that separating the solids from the liquids would increase the decomposition rate of the solid waste, keeping it drier as well, which in turn would decrease any unpleasant odours indoors. That was four years ago, and really, it was the smartest decision I could have made.The Separett toilet not only looks smart but it is the easiest, non fuss system you could use. For two people, the solid waste bucket gets emptied into the specially designated outdoor bin, for further decomposition, maybe once every 4 weeks. The liquid waste I simply diverted into the existing plumbing of the building, and there is no smell, none! Honestly, for a waterless system, it is clean and so simple to use that I don’t understand why every household, especially those in more densely populated areas, do not have one of these in their home. Not only that, but by doing a few very easy things to aid in furthering along the decomposition of the solid waste in your contained area outside, you can have the blackest, richest soil to use in your garden later! I will be using this system again, in a new building, soon to be completed, and when/if my current septic system in my own home finally requires a clean out, forget it, I’m putting in a Separett waterless toilet.”

– E. Posgate

“We really like the Separett toilet. It is perfect for the location of our log cabin in northern Saskatchewan. It works very well. This is a great product and the service we have recieved from you and your company has been exceptional. We truly do appreciate this service.” – Charles C.

“At first I was skeptical about the Separett being odorless. My first test the May 24th guys long weekend, do I need to say anymore. This toilet performed flawlessly, it’s easy to install, clean and maintain (emptied once a year). Need a new septic system? Why spend $25,000 when you can buy a Separett at a fraction of the price with less maintenance and hassle. – Barry J. Clayton.”

“I liked my brother’s Separett toilet so much I went out and bought myself one” – Wayne L.

“We love our Separett Villa. It is truly odorless and is very easy to maintain” – Bruce and Mary T.

“I love the Separett toilet. Works like a charm!” Brian L.

“This is one fantastic device!” Eric B.

Works perfectly.

I am impressed. I was doubtful that it would be truly odor free, but it is. Richard spent a lot of time with me on the phone, as I had many questions. Great customer service.

    I am hesitating between Separett Villa and Separett Week end. The cost difference is noticeable and they have the same description (a part from the aesthetical looks and the additional tap). We are just two people in a tiny house so I suppose Weekend would fit us? Also it seems the cleaning process of the Weekend model is easier than the Villa. I wonder if the tap could touch the solids in the villa? Could you help us choose?
    And do you ship to Quebec?

    • richardbrunt Post author

      There are two important differences. The Villa has a view screen, which hides the contents unless sitting on the toilet. To me, this is a big feature. Otherwise, as soon as you open the lid, you are staring at the last person’s poop. The Villa is guaranteed for 5 years and the Weekend for 3 years. I prefer the Villa for most applications. The cleaning/ emptying process is identical – the contents is contained in a compostable bag, and is dumped in a composter.
      Yes, we ship to Quebec. The warehouse is in Ontario.

  • Tom Steenson

    Does the plug for the fan fit into a regular outlet in the U.S.? What size is the urine discharge hose, how long is the one supplied, and how would an extension be added to it?

    • richardbrunt Post author

      The toilet is built and designed for the US. It plugs right into the wall, either with a standard cord (9200 AC) or a wall adapter (9210 DC/ AC). The cord is 3′ long. The urine hose is 1″ ID flexible water pipe. You would connect more hose with a 1″ OD connector.

    I have an existing composting toilet as an outhouse but plan to install a Separett closer to the house for convenience sake. It will be situated close to a heavy use outside area and I am concerned about odours coming from the vent. I regularly get whiffs from my existing one and was wondering if a long vent pipe would overcome this potential problem or would it reduce the efficiency of the fan.? Many thanks

    • richardbrunt Post author

      There will be some odor coming from the vent. I don’t suggest you vent it near a heavy use area. A long vent pipe, going up to the roof line, will eliminate odor. However, you can’t go too far, as that will reduce fan efficiency. About 16-20′ with two bends would be fine.

  • David

    The Separett is not a composting toilet, so I wonder why it is called that. A real composting toilet produces compost, and therefore has to be turned during the process. I have customers who thought it was. Disposing of raw waste is more of an environmental concern than actual compost. Letting urine run out on the ground is ‘third world’. I don’t know of an inspector in my area that would approve this process. I guess it could be treated like a pet pooper scooper bag, and end up in the landfill, like diapers.

    • richardbrunt Post author

      The Separett, like most urine diverting toilets, is a two stage system where material begins drying out and breaking down in the toilet, with the actual composting taking place in a secondary container outside. They are referred to as composting toilets because that is the best way to convey what they do, and the best way to think about them – they are the first stage of a two step composting toilet system. Unlike all in one, non urine diverting “composting” toilets (which often produce nothing even close to compost), the Separett produces inoffensive, partially dehydrated material that is very, very easy to compost. Often, the material removed from some “all in one” composting toilets is not fully composted (not even close). However, it has not dried out either. That’s bad. In that case, it’s hard to dispose of and extremely unpleasant to deal with.

      You don’t directly dispose of the partially dehydrated material from the Separett. You place it in a sealed composting bin, where it sits for about 6 months or longer. At this point it resembles rich garden soil, and is safe to put on non-edible plants without any environmental concerns. Inspectors typically want to see the entire waste management plan – not just the toilet you install. If they are simply approving an all in one toilet because in theory it should (but often does not) produce finished compost, they are seriously misinformed and putting people’s health at risk. They (and if no inspector is involved then the user) MUST ensure a complete and thoughtful waste management plan is in place.

      You do not let urine run on the ground with the Separett. It runs into a gray water system, French drain, or storage tank where it is diluted for use as fertilizer.

      If you are considering an all in one, non urine diverting toilet that bills itself as a true composting toilet, I suggest you do an internet search of the brand name, followed by the word “review”. Often, you’ll see these are terrible toilets that do not work as advertised.

  • jeff mullins

    does it work as well in humid climates like Oklahoma where it would be used most in the summer in an outdoor area with enclosed bathroom?

    • richardbrunt Post author

      Yes, but there are a few considerations. First, the footprint of the Separett is larger than the Nature’s Head, and it may not fit in smaller RV bathrooms. Second, the vent pipe for the Separett is 3″, and you’ll need space for that. Third, you will need a tank for the urine, as the Separett does not come with a urine tank. The urine drains out the back of the Separett at 7″ high, so the tank would have to be lower than that.

  • Emily

    Hello. I am I terested in knowing if you sell or can recommend the bin you use for the secondary stage of composting outdoors. Also anyone in upstate NY know if I need to get approval from my town to have such a bin on my own property? Do you sell the composting bags? Anywhere in NY City I can try one out?

    • richardbrunt Post author

      I do not sell the bins, but I do know that Home Depot sells a pretty good one. Just buy a good quality bin, and make sure there are no seams in the middle of the drum where liquid could leach out of. Most bins are fine, but there are a couple of poorly made cheap ones. Approval requirements vary widely, but most people do not need or seek a permit for the compost bin. Bags are available either through me, or at most hardware stores and Amazon. There is nowhere in NY that you can try one, sorry to say.

  • Michelle

    I’m thinking about using the Separett Villa 9210 for events that don’t have convenient access to restrooms. I would plan on using the toilet to hold the solids and a separate larger container to drain the liquid into. In that case, I’m wondering about the toilet to guest ratio. For example, if I have a one-day event with 100 people, how many toilets should be provided? I am thinking two, but wondering if I may need to plan to empty the solids once or twice during the day?
    Thanks very much!

    • richardbrunt Post author

      I would not recommend the Separett for heavy commercial use. It is not designed or built for that. It is well made, but not indestructible. Plus, you would not want to empty solids every day. They need a chance to dry out.

  • Steve

    We have been using a Separett 9011 for just over two years in country NSW, Australia. It has been a great investment for us. Easy to use, odourless (even in the summer), low power consumption from the P.V. system and it looks like a ‘real’ toilet so even the visitors do not mind using it

  • Philip

    My plan is to install a Separett with the urine drain pit, as pictured above. My question: should I line the pit with permeable landscape cloth to prevent soil from filing the space between the stones?

  • Sue B

    Hi Richard- I will be buying a separett toilet for my small house I build. I have to put in a septic (required by law which is stupid) but I will only use that for grey water. Is there an easy way to capture the urine? Does the unit come with a capture bottle? I like the nature made unit as it comes with the urine bottle in the front. Also do I need to elevate the toilet x inches to make sure the urine is collected in the bottle correctly? I don’t want to drain it into the soil like a French drain below the house, I will probably be on a slab. If I didn’t use the collection bottle how far could I run the drain tube away from the house. It obviously would be buried below the surface of the ground.

    I am toying with the nature made toilet for a metal building I am putting up. I may not have electric out there until I can get solar put in later. Any issues you might warn me about?

    • richardbrunt Post author

      The urine can be run to the gray water system. However, government authorities often do not understand that urine is practically sterile and poses no health risk – so they may not approve of that. You could run it into a tank. (After the inspector leaves what you do is your business). The urine drain exits the toilet 7″ above the floor, so you have quite a bit of drop without elevating the toilet. You can run the drain tube as far as you want, as long as it is always very slightly downhill. A French drain can be beside the house, by the way. It does not have to be under. The Nature’s Head has a collection bottle, which makes installation simpler but then you have to dump the bottle somewhere.
      Ventilation is not optional. Without the fan operating, you may get odors. There are those that claim certain toilets don’t need a vent or fan. This is utter nonsense. You can bury the waste under a huge mound of sawdust, yes, (and hope it doesn’t stink, it still might) but failing that you could have odors without a fan.

  • HelenT

    We have a weekend cabin that may have 7-20+ guests and only one water closet. Wondering if this would be a viable 2nd, or ‘back up’ option in an outhouse. How much action can these handle?

  • les

    oops we have the 9000 “DC”
    it is my opinion after reading various reviews of plumbers that changed my mind about venting out the side wall.
    So my hope is that venting out the gable end wall will be good. with the 2″ pipe.

    • richardbrunt Post author

      I think you mean the 9210 DC. Right underneath a soffit might not be great. Consider that a clothes dryer vents far more moisture directly out the wall. Each situation will be a little different. Unless you are right under a soffit, I’d go out the wall. 2″ pipe is not sufficient. You need 3″.

    Hi Richard,

    Is it possible to purchase your product for residents in Australia?
    Or would it be cheaper to purchase from Sweden?

    Thanks,

  • Dawn Williams

    We are looking at installing one because of lack of water, in place of a normal toilet. Since we have a sewer pipe for the regular toilet, how do you mate the drain into an existing sewer line without sewer smell coming back into the home?

    • richardbrunt Post author

      I don’t think you’d want to do that. You’d need a plumber, if you want to use the existing drain. He will install a cap, to block the sewer gas, with a small fitting for the drain hose, and a P trap for the urine drain. You’ll need to pour a little fresh water into the toilet’s urine drain after each use, to keep the sewer gases from coming up. Might be easier (a lot easier) to cap the sewer and run the urine into the gray water system.

      • Dawn Williams

        Thanks for the quick response. Will urine in a simple ( just going to mulch basins around our trees) greywater system have adverse problems for the trees?

  • Bill Greenberg

    Hi – we have a Sunmar in our custom built park model/cabin. Our experience is pretty much like everyone else we read – it doesn’t compost well, it’s disgusting to clean, etc. We stopped really using it. Seriously considering a Separett to replace it. I’m concerned about fan noise and electric use so I probably would want the DC version (but plugged in.) Is that DC fan quieter and still strong enough to get rid of odor?

    The Sunmar vent comes at an angle off the back and goes to the right side (as you’re looking at it.) Can you think of any reason I couldn’t adapt the Separett to use the same pipe? It’s under a counter but looks like I have enough room to turn and connect up to the vertical pipe. At the top of our vent now Sunmar gave us a larger diameter “diverter” that goes over the pipe – can we continue to use that or should we use something else. Not convinced the diverter actually keeps rain out.

    Also, the Sunmar overflow tube is just a small 1″ tube at the bottom left that we think is probably clogged up now because… well, nevermind – the whole thing is just gross. Do you think I’ll be able to hook that up to the Separett? If necessary I can drill a larger hole in the floor to accommodate a larger hose but if this one will work I’d rather just keep it. It will either go to a blue boy or a buried pit.

    • richardbrunt Post author

      The DC fan is about the same noise as the AC fan on low. I don’t have the actual decibels. It sounds like a quiet whisper. You would not want it in the same room at night if you are noise sensitive, but behind a closed door it should be fine. As a last resort, you can unplug it at night. The 12 volt fan is definitely strong enough to get rid of the odor.
      If you have enough room, there is no reason why you can’t use a transition to other 3″ vent pipe, I can’t really comment on what is possible in your specific situation. There should be no other devices hooked up to the Separett pipe – it needs its own vent.
      I am not familiar with the Sun-mar’ diverter’, but I suggest you use a high quality, screened vent cap. It needs to keep 100% of the rain out, as well as bugs. The Separett drain house is about 1.25″ outer diameter. It is possible that you can buy a transition piece, to adapt it to your existing 1″ tube.

      • Bill Greenberg

        Thanks for your reply. Do you have an example of the vent cap your mentioned? I’m going to have to replace what we have. Since we have electricity it sounds like there’s no reason to go with the DC fan – I thought we could save some power and it would be quieter but it sounds like on low it’s probably about the same anyway. Finally, how long does it take to ship to Massachusetts? We’ll probably be ready for it about mid-April.

    • Gabriella Morrison

      Hi Bill Greenberg. I don’t know if you are still looking for information on your questions but I have answers! 🙂 We had the same exact situation with our SunMar NE (we ended up dragging into the woods for it to finish ‘composting’). Fortunately we found the Separett and have been happy as clams since then. But to answer your specific questions, we used the same vent opening with the Separett as we had for the SunMar AND we used the same drain hole in our floor for the liquids. It was an easy transition. The Separett fan is quiet (we live in a 207SF tiny house) and we don’t notice it and as we off grid we were concerned about power use. But the DC fan only draws about 3w and granted it’s running 24/7 but it’s not enough to cause significant issues for us.

  • Dave Charlebois

    What is the composting agent for the Villa 9200? Other composting toilets require sawdust or wood chips. Where is the air inlet for the exhaust fan to draw from? Where is the 2nd exhaust fan mounted? Do the fans work in conjunction with each other? Thank you.

    • richardbrunt Post author

      There is no composting agent for the Villa 9200. The goal is to dehydrate the material, which rapidly renders it odorless, and shrinks it dramatically (increasing toilet capacity). The actual composting takes place in a secondary container, outside. This solves all the problems associated with older models of composting toilets. The air is drawn from the bathroom area. The toilet is not airtight. Air flows into the toilet constantly, drying the material, and exhausting outside. This is why there is never any odor. There is no second exhaust fan, so I don’t know what you mean there. Just one fan.

      • Dave Charlebois

        Thank you Richard. Please tell me the scenario of composting. You say the actual composting takes place in a secondary container, outside. Is that to say that the 30 days of poop deposited in the toilet is not composted until it is taken outdoors and a 2nd bagged container is inserted into the toilet? Also, I believe I read in one of the reviews wherein the author stated that men must sit on the toilet to urinate — is this true?

        Dave Charlebois

        • richardbrunt Post author

          The function of the Separett is to dehydrate the solid material, not compost it. This is because as soon as the poop starts to dry, the odor disappears. Inside the toilet will be dry, crumbly, inoffensive material, and tp (except for the most recent addition). It has not composted at this stage. The composting (the hard part) takes place in a secondary container outside. This concept – keeping the poop dry (or with some toilets like the Nature’s Head slightly moist), and completing the composting process outside, was the key to composting toilets becoming trouble free and practical. Some older composting toilet designs promised that you could just almost magically removed finished compost from the bottom of the toilet – and that all composting would take place inside the toilet itself. But that turned out to be a fairy tale, as a search of reviews for those models will quickly prove. Nice idea, but it usually doesn’t work.

          The reason many people recommend men sit while peeing into the Separett, is because the forward bowl, where the urine is collected, is fairly shallow. This means that there might be some splattering. It doesn’t splatter when I use it, and I always stand. It probably depends on the pressure! Some care is needed with aim.
