Handy Pod Toilets: Wetland plants naturally filter human waste

Problem:

Floating villages, mostly in South East Asia, generally flush their waste directly into the water beneath them. As these residents depend entirely on the water they live on (e.g. fishing, bathing etc.), this discharge has grave effects on health due to bacterial diseases.

 

Technology/Article: 

Handy Pods, developed by Wetlands Work, use local plants to filter sewage waste prior to releasing it back into the water. The waste is first filtered through local plants that soak up waste toxins, like E.coli, up to 99.999% without chemicals or power. The remaining cleaned water is then free to be released back into the lake.

An additional benefit is that this technology can be at low cost and using local materials.

This project has already been deployed in Prek Toal, a floating village on a lake in Cambodia, that is home to roughly 100,000 people.

Stakeholders:

  • Wetlands Work
  • Investors
  • NGOs
  • Floating village communities

 

Implementation:

  • Although cheap, Wetlands Work will need investors to raise capital to have this technology deployed in various other floating village communities
  • NGOs will need to implement this technology on the ground (teach communities how to build it, how to maintain it, the health and environmental benefits etc.)
  • Ideally, implementation would target lakes/areas where this technology has already been partially implemented because even if some villages on a given lake have the technology, but others don’t, then they will not get the full health and environmental benefits that come with such filtration.

  1. Great post! I found it really interesting how the article mentioned the use of hyacinth plants which can be used for filtering, as well as herbal medicine, however, its benefits can be outweighed by the toxic nature of the bulbs so I am wondering if that effects its use in this situation.

  2. Great post, thanks for sharing! This is a really interesting technology – the fact that it uses local plants and materials makes it appealing, easy, and cheap to implement. I agree with your point that in order for the technology to make a significant environmental impact, it will have to be implemented on a village-scale. Proper training on how to effectively utilize the technology definitely needs to be carried out, because if the users do not fully understand the benefits that come with the technology, they might not have enough incentive to properly maintain it.
