If there is one problem, look for other problems and solve them together:
Problem:Lack of efficient low cost sanitation
Other Problems:
Water scarcityWeak soils, erosion, Missing food securityLack of incomeToo few jobs
Waterless Soil production
(Urban) gardening
Jobs with the systems, greywater in gardening, black soil makes water, food, happiness and health

Ferralsol Terra Preta de Indio
Anthropogenic dark earth
Terra Preta: result of an 2000 years old successful sustainable soil and waste management
Dr. Haiko PieplowBMU
May 13th, 2011, Berlin Video Conference Berlin/St. Petersburg
Secret of Terra Preta de Indio:
- 2000 – 500 years old
- 16. century millions of people, today 350.000
- layers up to 2 meters
- fertile without adding artificial fertiliser
- multiple high yields
Composition: - around 10 % charcoal (biochar), - kitchen-, biowaste and excrements, - bones and - broken earthware, (lactofermentation and vermicomposting)

Toilets and resulting Dilution
Type of Toilet Daily Flow per P. Pro and Con'sFlushingtoilet
+ widely accepted- waste of water- high dilution
Vacuum-toilet
+ low water demand+ well developed (ships)- high-tec / expensive
Separatingtoilet
+ little water / little dilution+ simple fertiliser reuse- little experience
WaterlessUrinal
+ no water / no dilution- maintenance required
Composting-toilet
+ no water needed- high space demand- maintenance neededDesiccation toilet++ Desiccation for hot climates
