The population of Dublin City and its suburbs currently stands at 1.3 million and is projected to reach 2.1 million by 2022. There is pressure on its water supply system (inadequate catchment sources, ageing infrastructure including treatment facilities, and distribution network) with little or no spare capacity despite Ireland’s relatively high rainfall that is well distributed throughout the year; albeit the greatest rainfall occurs in the west and southwest and at some remove from Dublin. The current governance approach to addressing the projected water supply deficit relies heavily on a combination of identifying new supply sources to secure the long-term water supply needs of the city together with an intense drive toward achieving “demand-side” reduced usage and conservation targets in accordance with EU benchmarks for various individual and sectoral users. This potentially emerging crisis of water scarcity in Dublin, with drivers including population growth, greater industrial and institutional demands, migration, and climate change, has generated one of the most significant public water works projects proposed in Irish history, which is to abstract raw water from the Shannon River Basin in the midland region and, following treatment, pump it to a storage reservoir in a cut-away bog before piping to the Greater Dublin Area. The preparations for this scheme have brought to the forefront some longstanding Irish water resources governance issues and challenges. This provides a unique opportunity and imperative at this time to take a more comprehensive look at the decision-making process in this regard, one done in the context of new European and national policies requiring incorporation of integrated planning to sustain ecosystem services, water resources management, water services management, and flood defense principles, and one taking account of the current unprecedented state of flux in which water resources management institutions in Ireland, and in particular Dublin, find themselves following years of unconsolidated legislation and stand-alone institutions.

There is pressure on the current interbasin transfer could alleviate flood risks in the Shannon water supply infrastructure to meet ever-increasing demand with River Basin while also buffering a chronic potable water supply little or no spare capacity, despite the fact that Ireland has deficit in Dublin, such a transaction would have a negative relatively high rainfall that is well distributed throughout the resource cost and should be added back to the interbasin transfer’s year.

In simplest terms, discuss how these challenges might best be addressed within the environmental costs are equivalent to the hypothetical framework of Ireland’s new emerging water governance expenditures to remediate damages to water resources, e.g., fish institutions. Although many of the issues raised are not habitat, brought about by possibly illegal, poorly regulated, or individually novel, the combination of challenges faced by Dublin even perfectly legal abstractions or effluents/runoff to streams, within the newly emerging national governance framework i.e., “externalized costs.” These environmental costs are to be presents a unique opportunity to provide baseline information 1School of Biology & Environmental Science, University College Dublin, 2School of Civil, Structural & Environmental Engineering, University College Dublin, 3International Water Association, 4School of Geography, Planning & Environmental Policy, University College Dublin Ecology and Society 19(4): 10 http://www.ecologyandsociety.org/vol19/iss4/art10/ for future analysis on the evolution of water governance .

Although there are collaborative networks. several medium to small rivers and two canals within the GDA there are no substantial natural lakes within 50 km of the city.
