I am working with an urban community who live on the tidal estuary of a river. Houses closely packed together and are built on stilts. Some of the houses stand permanently over water while the tide floods under the others. The community practices open defecation under their houses. Given the high water table and flooding traditional pit latrines or septic tanks are not appropriate could anyone suggest a design which would be appropriate in this situation.
www.engineeringforhope.org has developed anultra low cost loo specifically for this purpose. You can see the basic design by following the links. For your application, the poop would be collected in a 5 gallon bucket with slits on bottom. The bucket with slits would sit inside another bucket which has a diversion tube to collect the effluent in plastic container like empty detergent bottle. Total cost ~$12 and easily transportable. There are many configurations,so this is not featured in the website yet. Composting site is necessary. Effluent is added back into compost pile with no odor. We expect to publish videos to train people how to make them and how to teach WASH hopefully within 3 months. Way too much to talk about here, but key to this is a micro business approach. firstname.lastname@example.org Collector.pptx
To prevent contamination of groundwater, the bottom of the pit should be at least 1.5m above the water-table level. And have a look on this link:http://answers.practicalaction.org/our-resources/item/ventilated-improved-pit-latrine
I have recently travelled to Cambodia and have come across problems such as those you have described in floating villages with similar challenging environments. I innovative product maybe something that could work for your situation.
