Purpose This paper aims to explore why a country with significant under-investment in water infrastructure has not successfully imposed domestic water charges. Drawing on an economization lens, it examines how an economy emerged in the imposition of water charges but was subsequently hidden due to their politically motivated suspension. Design/methodology/approach Drawing on documentary evidence, a theoretically informed examination of the “economization” process is set out. This examination recognizes the central role sustainability plays in water management but illustrates how sustainability must be integrated with environmental, social, economic, cultural and political factors. Findings The findings set out the challenges experienced by a state-owned water company as they attempt to manage domestic water charges. The paper reveals that while the suspension of water charges has hidden the “economy” within government subvention, the economic and sustainable imperative to invest in and pay for water remains, but is enveloped within a political “hot potato” bringing about a quasi-political/quasi-economic landscape. Practical implications The findings demonstrate how the effective and sustainable management of domestic water supply requires collaboration between multiple participants, including the government, the European Union, private citizens and the water protest movement. Social implications While highlighting the challenges faced by a country that has seriously under-invested in its water resources, the paper reflects the societal consequences of charging individuals for water, raising important questions about what water actually is – a right, a product or a political object. Originality/value Showing how an economy around domestic water supply in Ireland was revealed, but subsequently hidden in “the political”, the paper illustrates how sustainability is as much about economics and politics as it is about ecological balance and natural resources.
