When I first started planning the infrastructure here, I intended throughout to use Joe Jenkins‘ dry composting toilet system. Beautifully simple and easy to construct and maintain, convenient and portable, no requirement to separate urine from fæces, and an efficient composting system designed for optimum thermophilic decomposition. It’s no wonder Jenkins’ toilets have been dubbed ‘Loveable Loos’. What’s not to like?
Many people though are surprisingly squeamish about dry toilets. When I came across Anna Edey’s experiments with vermicomposting in Massachusetts 18 years ago for processing sewerage out of a conventional flush toilet, described on the website promoting her book, I was intrigued. The fact that it coincided with us beginning renovations on an outhouse toilet for the wee house (designed to be guest accommodation) seemed fortuitous. The outhouse was ideally situated for it and putting in a composting flush toilet for the guest accommodation seemed like an excellent idea. When we then discovered a nice old ceramic flush toilet bowl still in one piece at the local dump, it seemed to be signalling the perfect opportunity to give this method a try. Edey’s website didn’t give full details, but there was enough information for me to work the rest out for myself.
