Separett Villa 9215 AC/DC Urine Diverting & Composting Toilet

Looking for the most advanced Composting and Urine Diverting Toilet in the World? The Separett Villa 9215 AC/DC Composting and Urine Diverting Toilet is the most advanced, trouble free, composting toilet that exists for on grid or off-grid living.

Separett Villa 9215 is completely waterless and is also urine diverting; this means the Separett Villa 9215 composting toilet allows solid waste to be stored for disposal while liquid waste is safely diverted into a storage tank or wastewater system. This results in less frequent bucket changes since the liquids never mix with the solids.

The Separett Villa 9215 will operate on either AC (household, on-grid), or DC (battery/solar, off-grid) power! Separett Villa Toilet features a single speed fan, with adaptors for both AC and DC to support venting up to 20 ft. An AC only fan conversion kit is available for longer vent lengths. The DC adaptor cable uses a 5mm x 20mm type FST T2AL 250VAC fuse.

The Villa 9215 AC/DC Composting and Urine Diverting Toilet overcomes the ‘visual acceptance’ hurdle of changing toilet systems, as it looks very similar to a traditional water based toilet.

The Separett Villa ships set for connection to DC power of a battery. To convert for AC power – you simply unplug the DC lead from the fan and plug in the AC adapter – which is similar to that used for most portable electric devices.

For installation in properties what are not used for period of time, and power is not continual, we recommend that when closing up your property, you place the lid on storage container to eliminate the need for ventilation. Upon return, remove the lid and restart the fan for proper ventilation.

Acceptance of water-saving toilets in building codes varies from town to town. We recommend that you check with your local authorities regarding acceptance within your community and particular project.

Separett Villa 9215 Composting Toilet Power FAQ’s:

How often should the toilet be emptied?

If four people are using the toilet on a daily basis, then a container will last about 3 weeks, depending on how much toilet paper is being used. The Separett Villa comes with one container. When full the contents are usually placed in a compost bin on your property. See my page on composting human waste. It’s easy! But you need to be careful.

How is it possible that the container with solids so rarely has to be emptied?

Urine accounts for about 85% of the waste volume and is routed separately away from the toilet. This increases the storage capacity for solids greatly. The container is easily replaceable and if the amount of users increases one only change containers more often.

Are there unpleasant odors indoors?

No. If the fan runs continuously the there will be no unpleasant odors in the room. When installing the toilet, make sure that the venting pipe is properly sealed with silicone. The easily accessible fan filter should be cleaned
regularly as well as the insect net at the end of ventilation pipe.

Are there unpleasant odors outdoors?

No. Because the urine and feces are not mixed, there is never any latrine-type odor from a Separett toilet. A certain amount of odor may be present outdoors, however, when and shortly after the toilet is used. If the venting can be routed to the back of the house, it is usually suffice to just route it straight through the wall. If the venting pipe must be routed through the gables or to the front of the house, it should be extended upwards or routed through the roof.

Are there unpleasant odors from the leaching bed/soak-away?

No. It does not smell since the urine is let out under ground where it percolates harmlessly away. The drain rocks in the leaching bed are usually covered with landscape cloth, topsoil and grass. There is no way this can smell if done correctly.

Are there unpleasant odors from the Separett Ejektortank?

No. The urine odor is drawn into the toilet through the hose and then blown through the toilet ventilation system. By the time it is expelled outdoors, it has been mixed with so much air that the odor is unnoticeable.

Must the urine waste pipe contain a p-trap?

Usually not. The faint odor that may come from urine is drawn out through the venting pipe with the aid of the fan.

Are flies a problem with these toilets?

Problems with flies are uncommon with Separett toilets. There is a screen on the vent. Keep the fan switched on at all times just to be sure.

Should the fan operate continually?

Yes. This keeps the housing dry and extends the lifetime of the fan. If the fan has to be switched off, place the lid on the container and remove it.

Which is the best method for routing the venting pipe, through the roof or straight through the wall?

It is always easier to go straight through the wall. When routing the venting pipe through the roof, the work is more difficult, as is ensuring good seals. Remember not to route the venting pipe to the house entrance or other
places where people gather.

How much airflow does the fan create?

There is no simple answer to this question because the airflow is very dependent on the length of the venting pipe and the number of bends it contains.

Is an additional fan needed if you have a shower in the same room?

No! All ventilation from the bathroom shall go through the toilet fan that runs continually.

Does the venting pipe need insulating?

The Separett Villa toilet has a condensation collector and does not need to be insulated.

Can the ventilation be run through a chimney stack?

No. We advise against it since moisture from the bathroom can destroy the mortar joints. Also, the plastic ventilation pipe can melt if it is run through the chimney stack.

Where do I lead the urine?

You have three options for the urine outlet:

1) connect the hose to the grey water system.
2) make a simple leaching bed/soak away.
3) use a tank such as the Separett Ejektortank.

Can I extend the urine outlet?

Yes. If you need to extend the included 2 meter (6,56 feet) hose; a pipe is preferable. With a hose it is difficult to ensure a drop for the entire length. Indoors, we recommend waste water pipes with a diameter of 32-40 mm (1 ¼” -1 ½”) and outdoors pipes with a diameter of 50-75 mm (2″ -3″).

Does the urine waste freeze in the winter?

Not under normal circumstances. Urine freezes at about -5ºC (23ºF). Ensure that the urine waste pipe has a drop along its entire length and use at least 50 mm (2″) pipe outdoors. It may also be a good idea to insulate the piping sections that run outdoors.

How can I make a simple leaching bed/soak-away? (Also called a French Drain)

Dig a small hole in the ground, measuring about 2′ X 2′ X 2′ deep. Fill it with rocks. Before covering the leaching bed with soil, put landscaping cloth over the stones to prevent clogging. The urine outlet can be led through or under the plastic film. Please a check with local authorities if in doubt.

Am I allowed to connect the urine waste hose to the greywater system?

Urine is sterile and does not pose a health risk. However, the regulations vary. Please ask local authorities.

How steep a drop must the urine waste pipe have?

It is important that the urine waste pipe drops along its entire length, so gravity can drain all liquids. A steeper downward drop lessens the risk for deposit build-up of urine salts or ice.

Is it possible to reduce the risk of urine salt deposit build-up in the urine outlet?

Yes. We recommend rinsing the urine basin with a small cup of water after each visit. You can also place the Separett Bio Drain Cleaner in the urine basin. This tablet contains enzymes that prevent urine salt deposits in the urine pipe. However, if you still get blocks in the urine outlet use a liquid drain un-blocker.

Is it possible to lengthen the hose on the Separett Ejektortank?

Yes, the included 10 meter (33-feet) emptying hose can be lengthened up to a maximum of 20 meters (66-feet) and only with a ¾” hose. Do not use a normal garden hose adapter as a connector, as it clamps too tightly around the hose. Before you can lengthen the hose, remove the spray nozzle by heating the hose and the handle with, for example, warm water or a hot air gun. Use a piece of pipe and two clamps to make the joint. As a suggestion cut about 5 cm (2″) of the Ejektortank nozzle and use it as the pipe for the joint.

Do I ever have to add anything?

In the container inside the toilet, the contents should be left to dry and lose volume. Some people use a Separett Absorb in the bag inside the container, since it keeps the contents dry and thereby odorless.

Which type of toilet paper should I use?

You can use normal toilet paper.

Should I throw toilet paper in the container?

Yes, toilet paper helps keeping the contents of the container dry and divided which facilitates the handling after the storage period.

Does the toilet function in cold rooms?

Yes. Separett toilets are not room temperature dependent. Cool temperatures may slow down or stop the composting process, but it will resume when things warm up. Much of the composting actually takes place later, when you have removed the inner bin and set it aside as instructed.

Can I use bags in the container?

Yes. All our toilets are supplied with bags in order to simplify cleaning the container.

Can I use compostable waste bags?

Yes. We recommend using Separett Compostable waste bag since it designed to endure the conditions inside the toilet and during the storage period. It will slowly disintegrate in the ground or in a composter.

How long time does it take until the Separett Compostable waste bag disintegrates?

There is no simple answer to this question because the disintegration is depending of the biological activity in the ground or composter and to the exposure of sunlight. Since the bag is designed to endure the conditions inside the container, it will also disintegrate slowly in the ground or in a composter.

Can the toilet tolerate freezing temperatures?

Yes. Composting may be delayed.

What do I do when the container is full?

Put the lid over the container, tilt the container towards you and use the sliding surfaces to remove the container from the toilet. Once removed, open the lid, and put a shovel full of dirt or compost on top. Replace the lid. Leave a slight opening for air circulation. Place the container in a suitable location outdoors. Let it sit for six months, then put it on non-edible plants.

What happens with the solids inside the container during the 6 month storage period?

The bacteria in the soil “consume” the fecal pathogens, thereby rendering the contents harmless. It is then ready to be placed in a composting bin for use on non-edible plants or buried.

If I use the Separett Ejektortank only in the summer, what should I do in the winter?

Before winter you should empty the Ejektortank, since urine freezes at -5ºC (23ºF) and can cause the container and its pipes to break. If you still use the toilet wintertime one can choose to collect the urine in suitable containers for use in springtime or you can pipe the urine to a leaching bed, soak-away or to the grey water system.

Do I need to obtain permission from the authorities before installing the toilet?

Most areas approve of and support the use of composting toilets. However, regulations may vary.
