Hello All, as part of my Ph.D., I am developing a holistic evaluation and rating framework for HWTS. I am also trying to understand the deep dissemination of RO, especially in the Indian context. Also looking at the emergence of affordable, local HWTS products. I request all community members give their inputs, views, and leads/links.

Have you looked at Elrha's HIF work on evaluating household water treatment in emergencies? Although it is focused on emergencies, many of the criteria they outline are the same in a development context.

Thanks for your question @Gaurav Kapse5   Can you provide more details about the HWTS framework? Is it available for review?  

Regarding the RO market in India, @Suneel Rajavaram5  and @Lalit Sharma5 can help you. They are very knowledgeable on the HWTS context in India.  

Thanks,

Marcio
