Re: Innovative Flood Resilient Toilet ( Green Toilet) for flood prone and Water logged areas

Excellent job!

1. I'm interested in learning more about the treatment process involved in the technology.
2. Could you please clarify what you mean by stating "no OPEX involved"?

Cheers

Thanks for sharing.  That looks most interesting.

Can you share more about the way the effluent is filtered or treated.  Do you have a schematic to share?
Regards

Innovative Flood Resilient Toilet ( Green Toilet) for flood prone and Water logged areas

Hi Everybody 
There is almost complete lack of sustainable toilet technology for flood affected / water logged areas in most of the developing countries. This is a serious issue of sanitation in unsewered area for such conditions. 
Under the financial support from the FINISH Mondial, the Netherlands, I got an opportunity to provide technical support (providing design, drawing and training/capacity building to concerned persons) in implementing 2 units of household Green Toilets in Gaibandha Municipality, Bangladesh, last month. This toilet can be used uninterrupted even when flood water level in the area is up to 60 cm. In case of rural areas, where proper drainage system is normally not available, leaching of effluent from pits into the soil is the only option. Such leaching causes groundwater pollution, where groundwater table is high. Where groundwater is used for drinking purpose, it causes serious and irreversible effects on community health. In the case of Green toilets, there is in-situ treatment of effluent, and no chance or very little chance of groundwater contamination, even when the water table is one meter below the ground.  Toilet is made up of low cost ring channels -commonly found in Bangladesh, with bacterial growth media in the form of used cement bags. Such media floats vertically submerged throughout the water column. In this case, treated effluent leaches in soil in the chamber from the top of the soil surface. Therefore, there is no/least chance of groundwater contamination. CAPEX is low, with no any OPEX.
