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
  - Cost? Chriswaterguy to find out.
  - What's the status of the solid material afterwards? Can be composted?
  - Proven in the field, including Aceh.^{[verification needed]}
Ultra-cheap systems, based on the Kamal Kar's work. Any applicable to this situation? Chriswaterguy to find out.
