Simple toilet

Website: www.studio.moj.net
Simple toilet: construct a portable toilet in 15 minutes. Architect Andrej Pretnar has set up a website with instructions on how to use buckets and other waste materials to build a free household portable toilet, washbasin or bidet. This survival skill takes just an hour to learn and within 15 minutes you can convert a bucket into a toilet that will last a week before it needs to be emptied (based on 1/4 litre of water for flushing). The toilet can be connected to a bidet and washbasin to re-use the water. It can be improved to make a chemical toilet or latrine. The web site includes illustrated instructions on construction and operation. A free CD-ROM with a video showing the assembly procedure and operation is also available.
