The last great cholera epidemic in London was in 1866 in the East of the
city, which was not yet connected to Bazalgette's new sewers. The disease
was virtually absent in the areas with mains drainage.
A good way to catch cholera today, if you want to, is to eat a salad in a
country without a proper sewage system.
A flush lavatory piped to a sewage works is not the safest solution to the
problem because it is the most ecologically sound alternative. It is the
safest solution to the problem because it can be completely successfully
owned and used by idiots. Therein lies the challenge...
Best wishes

There was never such a thing as a waste product or waste stream - just a
resource which was unexploited. Only by exploiting such streams can we hope
to preserve our way of life.

describes the "Reinvent the Toilet" fair which "challenged inventors to come
up with a toilet that operated without running water, electricity or a
septic system. It needed to operate at a cost of no more than five cents
(3p) a day and would ideally capture energy or other resources."
