Toilet - sawdust. Water. Recycling

http://www.aselfsufficientlife.com/compost-toilet-the-sawdust-toilet.html

Toilet and washing up area at lower pitches.

Built to trees. Could grow into a treehouse toilet!

"The system is extremely simple. 

One bucket inside a wooden frame covered with a toilet seat. 

Each time a person ‘visits’ the compost loo they just cover it with a sprinkling of sawdust,

 then close the lid "

"If you’re a bloke and its sunny outside,

don’t bother visiting the sawdust toilet though,

cut out the middle man and head straight for the compost heap. 

That way the toilet bucket is a little less heavy when it comes to emptying time."
