Urban imaginations, imageries and conceptualizations are always plural and illustrate the formation of knowledge hegemonies. In this article, we engage with the problematic of reading infrastructures with a southern theory lens. We explore multiple imaginations, imageries and conceptualizations of the Kirulapana Canal in Colombo via everyday practices. Analysing the geographical imaginations of the state officials and residents, we illustrate (i) how varied imageries draws from the same hegemonic register, and (ii) how this process reinforces and correspondingly in-turn constructs hegemonic imageries. Using these illustrations, this article will broaden the southern theory discussions via analysing the everyday formation of the metropolis (concentration of knowledge and power) and knowledge hegemony.
