CampaignDescription
After riding in the scorching summer heats for 8 to 10 hours a day and earning less than 10 US Dollars a day, they have a tough time providing for their families as it is. Thinking about a safe source of drinking water is the last in the list of things they have to think about. The idea was to build a safe drinking water solution around their existing lifestyle - The Pedal Pure works with the kinetic energy generated by the rickshaw puller themselves as they pedal and take riders over to a destination of their choice. Once the ride is finished, the rickshaw puller gets to have a drink of the water that he himself filtered. With a membrane filter that filter’s out impurities, the Pedal Pure become a safer alternative to water in his and his family’s daily lifestyle.
Execution
With the help of the kinetic energy produced by the pedal, a peristaltic pump attached to the rear axle of the rickshaw, pulls water through silicone pipes into a membrane filter. The membrane filter is housed in an acrylic box just beneath the seating compartment.
As the rickshaw puller pedals, the peristaltic pump pushes the water to a safe water housing in front of the rickshaw.
Outcome
The product was implemented in 5 rickshaws in the city. Any innovation requires the acceptance of stake holders and the general population of a country. Because each Pedal Pure filter takes under 18 dollars to produce, the acceptance would ensure a mass production of the solution.
Relevancy
No matter how simple the technology is, the technique at times needs to be shown hands on. So, the idea of Pedal Pure was generated to give the migrant population of Dhaka city a safer alternative to drinking water, and show a direct link with the power of pedal and integrate it with the power to filter your own water. A self-sufficient approach needed to be shown to a problem as grave as unsafe drinking water.
Synopsis
Dhaka is a city known for it’s rickshaws – the pedal powered trishaws that are beautifully ordained and the most eco-friendly mode of transport available in the city. The city has over 600,000 of them, which serve the 20 million of its residents. Due to the huge requirement, there is a huge surge of a migrant population that come to the city in search of a better living – only to find conditions worse than what they were used to. In a country where over 4000 children die due to poor water and sanitation conditions – more than 65% of the population does not have access to safe drinking water. The objective was to provide a safer water alternative to the migrant population and their family members living in the city.
