The city of Patna generated 700 to 800 tonnes per day of municipal solid waste, and prior to 2008 had no door-to-door waste collection. Nidan formed self-help groups and supported them with micro credit financing. They piloted an initiative, ‘Chakachak Patna’ with door-to-door waste collection for 300 households. This was done by a professional workforce of safai mitras (cleanliness friends). The Patna Municipal Corporation recognized the value of this service and contracted Nidan to scale up operations to 5,000 households in 2008, by collecting a fee of INR 20 to 30 per month per household. Nidan operations steadily grew to 63,000 households in 2014 and it increased its workforce for Chakachak Patna from 4 to 332. Due to the value of the service, the fee increased to 30 INR 70 per month per household. As many of the safai mitras were women, Nidan also set up 10 creches to support 300 working women.
