Vidya, your picture is worth a thousand words. By myself, I was using that (a toilet seat on top of a hole in the ground), but for 40 people it's a bigger problem.  The biogas digester can be made to work in a commuity; I'll have to investigate it, but some forum people here have the know how.

with 40 people biogas may be an option, i would guess that centralizing the waste will be the biggest problem, handling fresh faecal matter should be avoided.
With so many people a compost sytem would work really well. I had originally thought to use the compost on my farm, but was amazed just how little volume it produced.
I would think with 40 people the construction of a toilet block would be particularly easy. Just double the bins in each cubicle. So for example, in one block have 3 toilets, thats 6 bins, 3 active, 3 in storage. As a rule of thumb it will take 6 people 1 year to fill one 1m3 collector. Asuming half male and female (if you want to separate the block) then 2 toilet blocks each with 3 toilets (6 bins) would be about right (you need a year really for the compost to activate, unless you employ solar collectors). This would rquire a structure 6 m long and at least 1m deep, not such a big structure really. Of couse several smaller units could be used, but 40 people would work best with 6 toilets.
