Do you or your partner just wish for a comfy toilet for your off-road travels? If so, don't be shy about speaking out. There are times when all of us dread going out in the middle of the night or worse still surrendering our tender parts to the sand-flys!

You may have wrestled with the old “porta potti” carrying it around looking for a dump station when you would prefer to be enjoying your trip.

Our new eco waterless toilet option is the genius of a customer. He and his wife had a major motorhome for several years and got fed up with the dumping station management. He also wanted reduced carrying weight as any type of maceration toilet uses a lot of water  (2-4 litres per flush just like home). So he installed this specific eco waterless toilet in his motorhome and never looked back! He has now ordered a Kimberley Kruiser with this option.

The eco waterless toilet is a “compostable” system.

These toilets are an engineering genius.

  • They are 100% eco friendly
  • They are waterless
  • They look like a flushing toilet
  • They take less than an hour per year to maintain
  • The pedestal is shaped such that it is unlikely to be soiled.
  • It is cleaned as you would a flushing toilet; just use eco friendly enzymes in place of disinfectant.
  • There is absolutely no smell in the bathroom; any odours are removed by a 12 volt fan.

Here is how it works to setup and use in a Kimberley Kamper:

  • When travelling, the toilet stores perfectly in either the front or right section of the gullwing storage box.
  • Because the Kimberley has a small 25W solar panel charging the batteries, there is enough power to run the small fan all the time.
  • There is a filter fitted with the fan pulling fresh air through
  • It takes less than a minute to remove the toilet from the front storage area and place in the toilet ensuite. This will take even less time if you store it on the right side of the Gullwing box and use the NEW for 2017 'Advanced Gullwing Ensuite' (where the toilet stays connected to power and sets up close to storage box)
  • There are two Ensuites available which work well with the waterless toilet - the 1.'Waterless Toilet Ensuite' (this sets up on the body section of the camper trailer with access direct from the inside the Kamper) OR the 2. 'Advanced Gullwing Ensuite' (this erects off the right side door of the Gullwing Box and provides acess to the toilet and hot water system directly)
  • It takes less then a minute or two to set up the shower and either toilet ensuite.
  • There is a 12V outlet dedicated to the fan system.
    Plug this in and loop the hose up and into a leather outlet.
  • Its that simple!
  • You can add an Upgrade which automates the turning of the internal mixer (which is normally done via an outside handle).

Here is the NEW for 2017 Advanced Gullwing Ensuite

Inside the NEW for 2017 Advanced Gullwing Ensuite - toilet is close to camper so very easy to move from camper.

Upgrade to the Automated turning system and you'll never accidentally neglect your duties.

What Kimberley Models can I add this to and how much is it?

  • You can add the Waterless Eco Toilet and your choice of Ensuite to most Kimberley Kamper models


Can I retrofit an existing Kimberley Kamper to take this?

  • No. Although you can buy a toilet to install the unit in the front Gullwing section, without the constant fan running the unit will not perform properly and is NOT recommended. Power is also needed when it is in the toilet suite. Also, the 'Waterless Toilet Ensuite' is a split ensuite design with additional Velcro on the Kamper wall to take the toilet ensuite and this can’t be added.


What happens at end of trip?

  • Leave the compost toilet in the gullwing with the fan running (remove and empty liquids tank though). The fan takes less than 1.5Amp hours a day and can continue to run powered by the solar panel if outside or from batteries and 240V charger inside. After approx. 3 weeks, it will be close to dust! Take out and discard in a plastic bag and place in rubbish bin. You could distribute over lawn or garden but for added safety we recommend discarding. The fan is disconnected when you take out so there is no switch to “power off”, it does this function for you.


Disposal

I think you have basically said to leave it for 3 weeks after a trip for decomposing, but what if you don't have 3 weeks of no use? eg a long tour/trip, or a series of short trips with short intervals between?

  • We recommend eight hours after last use before emptying. Using fulltime it will not be all composte: if for example 1 week, then 5 days again , then maybe a month before use it will go many weeks before needing empty. When using fulltime ideally emptied into a compost pile, or put into a plastic bag, in a bucket open with a ventilated lid it will finish composting, 30 days to 6 months depending on temps, the warmer it is the faster it composts. If just put into a bag and thrown in a rubbish bin it will finish.
    With Part time use: it may be 4 to 5 months before emptying. Our users guide described this properly.
  • There some five videos by Jason Wynn in a Fleetwood motorhome that have used this toilet fulltime for a couple years, also content on their website: www.gonewiththewynns.com The videos are very informative.


Composting/separating toilet – How it works?

You slide open the “safety” cover and use.

  • There is no water tank.
  • Has two tanks, one for solids and one for liquids.
  • You select which tank to use each time you start to use the toilet.
  • No water flush; liquids or solids fall into tank through gravity.
  • Typically 80 uses for solids, less for the liquids tank.
  • Couple should comfortably have 2-3 weeks or more before emptying.

Solids tank:

  • Start with a little peat moss.
  • Use crank to churn contents after each use.
  • Moisture should be kept low.
  • Uses a continuously-running fan vented to outside air with a filter in the air vent.
    This accelerates the composting process.
  • Full composting into safe compost depends on temperature and time. At above 55 degrees (compost temperature not ambient temperature) this is only hours; at 45 degrees this can take a day or so.
  • Need to wait 3 weeks or more (more is better) after last use. It will be close to dust! Take out and discard in a plastic bag and place in rubbish bin. You could distribute over lawn or garden but for added safety we recommend discarding.

Liquids tank:

  • Tank configured for easy removal and transport for emptying.
  • Adding brown sugar to tank will reduce any liquid odour.

Composting/separating toilet advantages:

Composting/separating toilet disadvantages:

80 uses are typical for solids tank

Consumes 12v electric power for fan and heater; which although small is still required.

Better for the environment than discharging natural waste.

Capacity constrained to about 80 uses and then depending on temperature system, there has to be a delay before emptying

Easy to operate.

You have to empty the liquids more regularly than the solids.

Lowest cost to use

Composting/separating toilet disadvantages:

No flushing or pumping (operates via gravity).

Consumes 12v electric power for fan and heater; which although small is still required.

Almost impossible to clog.

 

Few moving parts, and only one (vent) hose.

 

Lower weight and less space than a toilet-pump-tank setup.

 



Chemical toilet has one tank.

You slide open the “safety” cover and use.

    • There is no water tank, but there is water “feed’.
    • Liquids or solids fall into tank through gravity.
    • The “one touch” electric flush releases an amount of water into the storage container based on how long you hold the button down.
    • Typically 25-30 uses for solids, less if for liquids as well.
    • A couple should comfortably have 5 days before emptying.
  • Tank:
    • Is chemically treated
    • Is easy to remove and transport to dumping station for emptying

Chemical toilet advantages:

Chemical toilet disadvantages:

25-30 uses are typical for solids

Consumes 12v electric power for flush.

Easy to operate.

Consumes chemicals

Uses liquid chemicals or sachets so has a cost of use.

Capacity constrained to about 25-30 uses and then needs emptying

Can use “reclaimed water” from selected grey water tanks to “clean” the bowl of paper and residue.

If you use for liquids as well then number of uses reduces.

No active flushing or pumping required though (operates via gravity).

You have to empty manually

Almost impossible to clog.

 

Few moving parts, and no vent hose.

 

Lower weight and less space than a toilet-pump-tank setup.

 



Vacuum toilet is the latest technology as used on all aircraft.

You simply sit and use.

    • There is no water tank, but there is cleaning water “feed” line.
    • Liquids or solids are pulled through to tank by vacuum.
    • Pressing the foot pedal or button opens the “roll over” trapdoor at the bottom of the toilet and the vacuum sucks out the waste. The longer you hold, the more sucking action.
    • The water is used purely to “rinse” the bowl of paper and residue.
    • Based on a 25 litre tank, typically 35-40 uses for solids, less if for liquids as well.
    • A couple should comfortably have 7 days before emptying.
  • Tank:
    • Is kept in a vacuum
    • Has to be "dumped"
    • Is easy to dump from at a dumping station.
    • Water flush point is used to clean dumping hose at dump station
    • Transfer case can be used if not possible to get close to dump point

Vacuum toilet advantages:

Vacuum toilet disadvantages:

35-40 uses are typical for solids

Consumes 12v electric power for vacuum and pump out.

No odour at all, and therefore no vent hose.

Higher capital cost

Easy to operate.

Capacity constrained to about 35-40 uses and then needs emptying

No cost to operate (other than 12v power for vacuum pump)

If you use for liquids as well then number of uses reduces.

Environmentally preferred as waste has no chemicals

YOU HAVE TO PUMP OUT

Can use “reclaimed water” from selected grey water tanks to “clean” the bowl of paper and residue.

 

No active flushing or pumping required

 

Almost impossible to clog.

 

Vacuum system and pump out system uses diaphragm pumps so that waste does not actually pass through a pump blade or shaft

 

Can be emptied anywhere that will accept waste as there are no harmful chemicals to the environment

 



Macerating toilet (designed for boats and sea water)

You slide open the cover and use.

    • There is a water tank. This can be seawater.
    • Uses a single “macerating “ blade to shred and pump waste
    • Uses a lot of water to flush; liquids or solids are pumped into tank.
    • For a 60 litre holding tank. This may start at 2litres per flush when new but may be as much as 4 litres per flush, so 15-30 uses for solids, less if with liquids. You can compare to a conventional toilet at home and water used.
    • Couple should comfortably have 4-6 days or more before emptying.
  • Macerating pump:
    • High end systems separate the macerating stainless steel blades from the actual pump. (less maintenance and trouble)
    • Lower end systems have a single macerator/pump blade.
  • Holding tank:
    • Because a lot of water is used for flushes, a large tank is needed.
    • Can be stored under caravan.
    • Is easy to dump from at a dumping station.
    • Water flush point is used to clean dumping hose at dump station
    • Transfer case can be used if not possible to get close to dump point
  • Water tank:
    • Because a lot of water is used per flush, larger water tank is needed.

Macerating toilet advantages:

Macerating toilet disadvantages:

Perfect for marine when plenty of water available (raw water can be used)

Prone to odour as no chemicals and no vacuum. Needs perfect seals.

No chemicals used

Waste travels through macerator so higher chance of blades/shaft blocking. Very unpleasant for maintenance.

 

Heaviest and least efficient system on land as a lot of water is needed for flushing; so large water tanks and holding tanks provide low capacity for no of uses.

 

Lower capacity for weight and size to any other system.

 

Consumes 12v electric power for pump.

Kimberley wont offer a maceration system as the amount of water needed per flush is around 2-4litres for an odorless environment. This is too wasteful with resources and still leaves piping open to residue. The maintenance of the maceration system is unpleasant as the waste MUST pass through the pump blades which is a source of problems.
