Revision as of 03:48, 20 February 2010
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, too large scale for the specs; for longer term settlement (due to capital cost, time for construction); relatively unproven. (E.g. Bio Latrines in Kenyan Slums.)
- Non-composting, non-biogas toilets
- Emphasis on public health (rather than sustainability or treating the waste as a resource).
- 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.
- What about small community based Constructed wetlands?
- Sawdust bucket toilet, after Joseph Jenkins' "Humanure Handbook" (fundamental reference on this topic, free to download) -- hygienic, private, cheap, hard to screw up, makes great compost... why aren't you using one?
