$120,0000 grant from 2020 to 2021
The grant will enable Aerosan Sustainable Sanitation to build and manage 2 additional toilet HUBs in Kathmandu, for a total of 6 functioning facilities.
Aerosan has developed a public private partnership for pay-for-use public toilets, in densely populated areas of Kathmandu, which are user-centred revenue-generating enterprises that have proven to benefit the community. These HUBs are female-centric, providing a clean and safe environment with all necessary sanitation, MHM and hand-washing facilities. They also incorporate an in-situ waste-to-value system whereby human waste passes through an anaerobic digester, producing biogas which is sold to adjacent tea houses, and at the same time, saving 24 Mt of human waste/HUB/annum from entering the environment.
Critical to the operations of the HUBs, is the Sanitation Workers Co-op, made up mostly of women from the Dalit caste – formerly untouchables – who Aerosan trains in literacy, numeracy, cleanliness and operational management and offers them well-paid and dignified employment.
Aerosan’s innovative new cleanliness protocol was developed by Temple University’s School of Public Health. In addition, Aerosan has a partnership with MIT’s ALM Laboratory to develop community disease profiling – including for Covid-19 – of the waste from the HUBs. To date, Aerosan has built or renovated 4 such HUBs in Kathmandu and our pilot HUB showed a 46 % increase in female users and a 43 % rise in hand washing. These 4 HUBs will, over a year, accommodate over 1 million toilet usages.
The Aerosan HUB model is designed to scale in order to improve reliable sanitation access to underserved communities with the use of remote sensor monitoring and cross-subsidisation
