Wet toilet options for flood prone areas

Hello,

I am wondering if anyone has any practical examples of wet toilet design options for flood prone areas? I am particularly interested if there is evidence of pour flush toilets to raised alternating lined pits which drain to a raised infiltration trench?

Thanks!

Re: Wet toilet options for flood prone areas

Dear Katie,
I am no expert in toilet technology, but anything that needs draining water to the earth may become dysfunctional during the floods. I am sure experts in emergency sanitation will direct you to appropriate resources.

Till then, attached is a presentation by Megh Pyne Abhiyaan (MPA), an organisation that has championed implementation of UDDTs in flood prone regions of Bihar, India. It is also available here . Alternatives mentioned in the presentation include one with facility to drain ablution water. MPA calls it 'phaydemand sauchalaya' (profitable toilet in Hindi) to convey savings on health expenditure post floods. The presentation also includes images other experiments including mounting them on cycle and tractor trolleys to make them mobile to be deployed during the floods.

Hope this helps.

Regards
Paresh

Re: Wet toilet options for flood prone areas

Hi Katie,  

Good question, and it is challenging, it can work but with very complex technology like vacuum sewers, which are used in some developed country context with flooded prone area or at least a very high water table. However, it requires a lot of technology, energy and maintenance which makes it unaffordable or inappropriate for most places in developing countries context. 

There is no easy option for the flood-prone areas and that's why we developed with Loowatt CBS services for those areas, flush toilets without water (but washers are welcome to use water, as we also developed the system in the Philippine ), and regular service, if you want to discuss more the technicality of such option, or other options for your challenge I am happy to have a discussion about it! you can contact me This email address is being protected from spambots.
