Reimagining urban design of stormwater infrastructure in settler-colonial Sydney

Although many might consider the Australian city of Sydney as defined by golden beaches and a glittering harbour, the city actually has an abundance of wetlands—swamps and marshes laid out across the eastern Sydney region. Dramatic transformations of these waterscapes have taken place since 1788, when British colonists landed to form the settlement there. Environmental exploitation has been a key part of settler-colonial projects across the world. Sydney is no different. To contextualise this exploitation, I explore the ways in which a specific water infrastructure system in Sydney—the Tank Stream—has been entangled with, and is emblematic of, settler-colonial politics. I argue that to reimagine futures where such ecologically and culturally damaging infrastructures no longer have a presence in the city requires a nuanced interpretation of both water and history. I suggest that “conventional” stormwater design features emerged from colonial viewings of Sydney’s waterscapes. The transformation of these geographies was imposed on existing water management systems, set within local, First Nations knowledges. Thus, I also consider the Tank Stream as a site with potential to present an anti-colonial hydraulic urban co-design framing. I draw on colonial archival material and field site visits to question the importance that settler-colonial urban design has had in shaping contemporary ways of thinking about watery spaces. I conclude by arguing that the hydro-imperial knowledges must make way for a culturally inclusive urban water design that centres and elevates First Nations design.
