The Separett Villa toilet is a clever device. It separates the urine from the solid matter. The urine can be easily disposed of in many ways - down a drain, in a public toilet, even in a hole in the ground (with permission). The solid matter is composted in the unit and need only be emptied after several months to a year, depending on usage. There is a very low power consumption fan which draws air over the compost and ensures good moisture evaporation and decomposing of the waste.

These toilets can be used in houses, boats, garden offices, churches, allotment sites, motor-homes, caravans, horse-boxes, in fact anywhere that needs a toilet! Connect the Villa 9010 to a urine tank if you want to use the urine as an organic plant nutrient.

Waste Storage/ Disposal

With the Villa toilet the urine and the solids are seperated. The urine is disposed using a tube from the toilet. We can provide the toilet with a tank that can be mounted besides or behind the toilet to store the urine, if disposal is not adequate in the toilets environment. The solids are collected into solid bins that are supplied with the toilet.

You receive three solid bins when purchasing this toilet and this is designed so that by the time the third bin is full, the first will be composted.

Our products and solutions are no different from any other appliance buy or home/ office improvement you make. Apart from that they tick all our boxes.

To help makes things easier for you, we've given a guideline on the approximate skill-level and time involved in the installation of this product:

1. Why doesn’t it smell?

People asking this question are either thinking about the smell of sewage when near a sewage treatment plant, or have experience of chemical toilets or smelly ‘deep drop’ composting toilets, often at festivals or events.

Urine, when it comes out of us has a mild smell which varies according to our diet. This reduces as it cools leaving a fairly innocuous liquid. If it is added to water and left to stand then the combination of nitrogen in the urine and hydrogen in the water over time combine to form ammonia. By either running the urine into the ground using a soakaway or emptying a collection tank regularly, this is avoided.

Faeces, when they come out of us, contain vast quantities of micro-organisms. Almost all of these are aerobic bugs, which need oxygen, break down our ‘waste’ into harmless compost and create no smell. Only a few are anaerobic bugs, which don’t need oxygen and make a stink whilst breaking down our waste. Using any other form of toilet ensures that the ‘good’ bugs are drowned immediately, leaving only the ‘bad’ ones to create smelly sewage sludge. The dry conditions in our composting toilets, along with the fan providing a good supply of oxygen for the ‘good’ bugs means that not only does composting happen quickly, but also that it happens with virtually no smell.

2. Do I need to use special toilet paper?

It is not necessary to use anything other than your normal preferred paper as all toilet paper breaks down to compost along with the human faeces. However some papers break down quicker than others and those wanting to produce good compost in the shortest time should consider using leisure brands of toilet paper (e.g. Thetford, Elsan, Fiamma) or cheaper brands. Expensive quilted brands, such as Cushelle, should be avoided as they have a high proportion of plastic within them and are not good for the environment as well as being very slow to break down.

3. How do I keep the toilet clean?

First of all it should be noted that dry toilets tend to remain cleaner than WCs as it is almost impossible to soil the surrounds of the bowl if used correctly. However, if you should need to, or want to clean the toilet, it is important to only use environmentally friendly cleaners – we recommend Ecover Bathroom Cleaner, but other brands are available. This ensures that nothing enters the toilet which could spoil the microbes producing the compost. If the toilet is wiped with toilet paper or kitchen towel then the used paper can be added to the solids container to break down along with the other contents.

4. How easy is it to install a composting toilet in a building?

Extremely simple. {The Separett Villa is fixed either with three screws into the floor, or with a bracket to the wall behind./ The Air Head is fixed with two floor brackets.} The air vent must be connected to an outside wall. This is normally straight through the wall beside or behind the toilet, but can be ducted either through the roof or at ceiling height to an outside wall. If a roof space is well ventilated it can be ducted there. The power supply should be connected to the fan – this can be a 12 volt supply, a 230 volt socket, or, if in a shower or bathroom, a fused spur.

The toilet will then be set up with a small layer of starter material, typically cocoa shell and is then ready for use.

5. What do I do with the solids when the toilet is full?

This depends a lot on your circumstances. For many people the simplest solution is to empty the contents to an existing or newly installed composter – to be used with other garden and kitchen waste once composted. For others it is stored in bins supplied with the toilet until fully composted and then either added to the garden or disposed of with waste (typically in green wheely-bins).

For those living and moving continuously in boats or motor-homes the solution is usually storing the bins in a locker or engine room until fully composted and then either digging into a local field (with permisssion) or bagging and disposing at a rubbish point. Those with friends or family with gardens or allotments can often persuade them to accept their fertile offerings.

6. How long will it take for the solids to break down into compost?

The breakdown of human faeces into harmless compost starts to happen within the toilet, especially if the toilet is not in continuous use. The speed with which this happens varies largely dependent on the warmth of the environment. In warm conditions this can be 6 months, whilst in colder conditions it can take as long as a year. For this reason we encourage storage of composting material in a warm place, or adding it to an existing composter, where other kitchen or garden waste can assist with composting. For those wanting to break their waste down in the shortest time, we recommend the ‘Hotbin composter‘. This well designed product encourages high temperatures in the compost and can render human waste as compost in as little as 90 days if well managed.

In order to ensure that all pathogens or other harmful bacteria are neutralised, the Environment Agency advise that such compost material should be kept on site for 26 weeks, but after that time it can be removed to another site or disposed of in domestic refuse or recycling systems.

7. How can I dispose of the urine?

This depends on your circumstances and whether you are a keen gardener. For many people the easiest solution is to run the urine directly from the toilet into a small soakaway in the ground. In most situations, this only needs to be about 500mm x 500mm filled with gravel and usually finished off with grass on top. Since the urine is going immediately into the ground and is excellent fertiliser, having a high nitrogen content, there is no smell from the soakaway and plants nearby will thrive on the added nutrients.

For keen gardeners, it may be preferable to collect the urine. This can then be removed for use either directly around plants or added to a composter to improve composting. Alternatively, by diluting with water to avoid damaging delicate leaves, the mixture can be sprayed over plants. This can improve crop yields dramatically as shown by many trials, especially those carried out in the USA and Africa – 8 fold increases have been reported.

For those in mobile applications the urine can be disposed of simply by pouring it under a hedge or in the undergrowth either on the towpath, the river bank or at the roadside. Since urine is sterile and counts as grey water, this is quite legal and adds useful nutrients to the soil as well as removing most of the volume of human output. In this way mobile users can avoid the need to search for disposal sites and minimise the volume of storage space required.

8. How often will I need to empty it?

Obviously this depends on usage, but as an example, two people living with just this toilet would take at least 10 weeks to fill the solids bin. Since the toilet is supplied with three bins, this allows 30 weeks before the bin needs putting back into use. If the contents are emptied directly into a composter then only one bin is needed. For other users such as garden rooms, allotments or churches the solids tank may last 6 months or a year before being filled, since the usage may not be continuous and my be mainly for urine.

If urine is run off into a soakaway, it will never need to be emptied. If it is collected in a container then the time to fill this will depend on the size of the container – a 25 litre tank will typically accommodate over 100 uses, whilst a 50 litre Ejektortank will allow over 200 uses.

How do I clean the blue screen in the toilet?

This is a common question and one which is easily answered. As long as people sit on the toilet to use it, the blue screen moves out of the way and cannot be soiled, therefore it should rarely need cleaning. The only time this panel can be soiled is if users squat above the toilet, or if men stand to urinate. It is therefore important that all users appreciate the importance of sitting down on every visit.
