We are getting ready to purchase a new Casita Indy and wondering if anyone has recent experience with the new composting toilets? Does anyone know if they are an option on a Casita? 

Thanks! Holly & Fred

we just had a lively discussion on the topic, as a matter of fact. "bex-cat herder" is a lady full timing in her 1985 casita Patriot Deluxe and she shows details on "youtube". while there are pros/cons to it, just like everything else, i think it's a definite possibility for those of us who boondock frequently, where water conservation is important. a well maintained and properly used compost toilet, just like a regular toilet, is a very clean alternative, no smells, etc. of course, anyone who misuses/neglects the recommended compost toilet procedures may report something negative about it, but that's not a reflection on the compost toilet. good luck with your decision...................

We recently toured the (nearby) Oliver Trailer  factory in Hohenwald TN, where the nice tourguide informed us, during a 2 hour plant tour,  that more and more folks were ordering THEIR trailers with the "new composters".   Oliver goes ahead and installs the plumbing and blackwater tanks FOR a std toilet, so that an owner CAN easily switch back to the Stinky Slinky type at a later date.   Oliver may have hopped the shark on this installation.  I still wish Casita had this as an option.

Well, you DO have this option in your Casita- you have the black tank plumbing installed as standard.  Take out the standard WC and pop in a composting toilet.  Buy it from Oliver, and maybe you can get them to install it.

While I like the concept of dry composting toilets, frankly, having some experience in the field of microbiology, my interest is the "safe" disposal of human solid waste.  ("Safe" as in Public Health Safety).  Public Health laws exist because untreated human solid waste contains pathogens and viruses that are dangerous to humans.  Solid waste that is not treated in conventional sewage treatment plants, will need certain conditions and lots of time to break down. 


IMO, this informative article covers the subject of RV Composting Toilets very well.  It's rather long but well researched; it includes information on the legal and safe disposal of human waste.  The authors have written articles for Trailer Life Magazine and Motorhome Magazine.


Eco-toilets answers this question: How long will it take for the solids to break down into compost?


The breakdown of human feces 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 ‘Aerobin 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 neutralized, 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.

We Americans have fallen way behind the rest of the world be it composting toilets or the so called "leadership" program we "elected", may the gawds be merciful upon our souls.

Anyway, the innovators of progressive "camping" down under are leading the way, Rice like the rest of rural Texas is so far behind the idelogical curve that they're no longer on the road.

Innovate or die it is said.

Way to make toilets political. :rolleyes:

On the actual subject of composting toilets, I am skeptical of it being as useful for my family, as I imagine I would have to be dumping the bin, far sooner than required to accomplish the composting.
