This article examines the social and political aspects of late nineteenth-century water management in Batavia (now Jakarta), the capital of the Netherlands Indies. Through a detailed analysis of how a mixture of old and new water technologies featured in the city’s public debates and decision-making, it argues that water infrastructure served as a key site of social control over the city’s diverse population. From the 1870s onwards, deep-bore artesian wells linked to public hydrants were introduced to provide a reliable and hygienic supply of clean water. This was a response to long-standing concerns over the city’s waste-blocked canals and their deleterious health effects. The article shows how these technologies came to be entwined with new, punitive social norms, enforced through both formal regulations on water use and informal complaints over wastefulness; moreover, these norms had a clear racial dimension, being directed primarily against the city’s Asian communities and repurposing long-standing stereotypes. Yet, beyond official discourses, a close reading of these debates shows that Batavia’s canals and hydrants also functioned as grassroots sites of negotiation, where different ideas – not just of water and land but of the very concept of public spaces and the colonial public sphere – met and occasionally clashed.
