Everyday practices and technologies of household water consumption: evidence from Shanghai

A social practice approach to household consumption examines socially produced patterns of practice, and understands these to be composed of technology, knowledge and meaning. This approach challenges many of the assumptions made about how consumers who are supposedly economically rational behave in large-scale municipal water supply systems. Yet for an emerging body of scholarship that is sensitive to the effects of context, research on social practices is notably short of studies beyond wealthy liberal democracies. In this paper we examine the key practices of daily water consumption for households in Shanghai, China. We identify boiling water, filtering water, and buying water as the three key practices associated with daily water consumption in the home, and explain the way each is the result of combinations of knowledge, meaning and technology. We also consider short-term and longer-term shifts in practices, and explain the influence of the materiality of pollution, information and trust on these changing practices
