Possibly as cheap as $20 per household in warm areas, assuming shared toilet banks. Practical, realistic designs have not undergone the "value engineering" necessary for this application yet, so are still too costly, although clearly a cheap, basic, functional unit for any given climate could be created. | Possibly as cheap as $20 per household in warm areas, assuming shared toilet banks.

Substitute for pit latrines, septic systems or conventional sewage handling with:
- area-appropriate composting toilet design
Financial model:
Possibly as cheap as $20 per household in warm areas, assuming shared toilet banks. Practical, realistic designs have not undergone the "value engineering" necessary for this application yet, so are still too costly, although clearly a cheap, basic, functional unit for any given climate could be created. Water System
Priorities
- public health is the overwhelming priority.
- low cost is essential - if it's not cheap, it won't be used as much and won't achieve as much.
- low ecological impact is very desirable if it doesn't compromise public health.
- suitable for various cultural practices. Target users may be accustomed to using water to cleanse (but can most often cope with small amounts of water), or other W methods, so the device should ideally tolerate sticks, rocks, paper, or whatever else is likely to be thrown in.
Options
- Composting toilet
- Biogas toilet, e.g.
- Non-composting toilets
- e.g. the W
