Vermifilter toilet

Vermifilter toilet, also known as a primary vermifilter, vermidigester toilet, tiger toilet or tiger worm toilet, is an on-site sanitation system in which human excreta are delivered from a toilet (usually by flushing) onto a medium containing a worm-based ecosystem. Faecal solids are trapped on the surface of the vermifilter where digestion takes place. Liquids typically flow through drainage media, before the effluent is infiltrated into the soil.
