Characterizing the dissemination process of household water treatment systems in less developed countries
conference contribution
posted on 2018-02-12, 15:09 authored by Tommy K. Ngai, Richard FennerRecently, household-level water treatment and safe storage systems (HWTS) have been developed and
promoted as simple, local, user-friendly, and low cost alternatives to conventional municipal-level drinking
water treatment systems. Yet, despite conclusive evidence of the health and economic benefits of HWTS, the
implementation outcomes have been slow, reaching only approximately 5-10 million people. This study attempts
to understand the barriers and drivers affecting HWTS implementation. A review of existing literature
on HWTS implementation found that existing research effort to promote HWTS is rather fragmented, with a
narrow focus either on technical, psychological, or marketing perspective. Also, the application of innovation
diffusion theories on HWTS implementation has been largely unexplored. To fill these research gaps,
it is proposed that a system dynamics modelling approach to characterize the complex diffusion process of
HWTS can be a valuable tool to identify high impact, leverage strategies to scale-up HWTS adoption and
sustained use.
