Saturday, September 10th, 2011:
One of the earliest decisions as we began wrapping our heads around this tiny house project was to depart from conventional plumbing and pursue a composting toilet. We decided to take this leap for two reasons in particular:
-We did not want to be tied to the demands related to proper disposal of black water, wich really limits where a tiny house can be located.
-We felt like we had a real opportunity to re-evaluate our impact with this project. While we do appreciate the luxury of conventional waste management, it really is staggering how much water is actually consumed to dispose of our waste. We had the ability to make a deliberate and conscious choice regarding our waste, and took the opportunity.
We researched many different types and brands of composting toilets, eventually landing on the Biolet 10 Standard. We like the simplicity and features of this particular model, and felt like it would be the best fit for our needs.
The installation was a bit challenging as it required venting for the composting system to work properly. We opted to vent out the bathroom wall as opposed to up and out the roof. Cutting a hole in a wall seemed a bit more manageable than through the ceiling and metal roofing, though it then required navigating a couple of 45 degree angles.
Another challenge was that the vent pipe must be insulated anywhere it is not kept warm by the interior of the house. We ended up ordering another length of exterior vent pipe as well as two of the 45 degree angle fittings from Biolet to complete our project. Otherwise, every thing we needed for this unit came with it in the box.
