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.
A 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.

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 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 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.

“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.”

“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.”
