The socio-entrepreneurial start-up Wetlands Work! received a grant in Round 7 of the Bill and Melinda Gates Grand Challenges Exploration program. WW! has developed an individual household wastewater treatment system that uses floating “Pods” - similar in appearance to children’s wading pools - that are positioned directly under the toilets of houseboats occupied by low-income fishing families. Similar to aquatic mesocosms, the Pods are filled with floating plants, and the bacteria that reside on the plant roots are capable of breaking down contaminants and making the water significantly cleaner. Presently, Pods are installed throughout an entire floating community and data on water quality (indicator organisms) and diarrheal incidence (children 10 yrs.) are monitored and compared to a control village without pod intervention.
