Getting Clean Water
While many in Bangalore depend on packaged drinking water services, others rely on in-house treatment systems for the water piped directly to their homes. While some systems like reverse osmosis and ultraviolet irradiation require a high upfront investment, other more affordable but slower options include gravity filtration and boiling. Despite their respective disadvantages, the city’s high […]
Bangalore Income Patterns
Income plays a big role in how Bangalore’s residents address their water contamination. While reduced water quality is almost ubiquitous throughout the city, many can afford to either buy clean, prepacked water or invest in household treatment systems. Therefore, Pure Paani has endeavored to develop a model of the city’s income patterns by ward. By […]
Bangalore Factor Integration
In order to understand which regions of Bangalore would most benefit from affordable, portable water treatment services, Pure Paani has combined Janaagraha’s 2013 water quality data with the 2011 Indian Census’s household amenity data as a proxy for income. This process presents an applicability score, out of 5, for each ward. A ward with a high […]

She serves two roles, that of a […]
Original Device Prototypes
Pure Paani is exploring an array of distinct pump filter prototypes in order to determine which systems work best in low-income communities. Such devices need to be effective and portable while also being durable and affordable. The two most feasible filter types include hollow-fiber, ultra filtration membranes commonly used in gravity and RO systems and […]
Filter Testing
Overview We want to incorporate a filter into our device that provides a high standard of contaminant reduction while operating at a high flow rate. In pursuit of such performance, we’ve decided to experiment with “ultrafilters” used in Kent-brand gravity systems. These filters route water through a bundle of “hollow fibers” which impede the progression […]
