  13. Singeapór / Singapore – A zero waste approach to water in action Bailiú Báistí / Rainwater Harvesting Bailiú Báistí ó cheantair cosanta agus neamhchosanta / collected from unprotected and protected catchments Uisce Impórtáilte Imported Water - ó Mhalaeisia - Malayasia • NEWater • Uisceathshlánaithe ó thionscail • Reclaimed water for non potable industry • Díshalannú / Desalination • Athshlánaithe • Uiscenafarraige (amachanseo) • Reclaimed • seawater (future) “Water dominated every Government policy” Prime Minister Lee Hsien Loong

  14. Philadelphia– Community Involvement in Design / Operation / Management of City Water Catchments “As we evolve Philadelphia into America’s most sustainable and green city, the opportunities ahead will be limited only by the confines of our imagination and the extent of our determination” Philadelphia Water Commission “Cities across America are now looking at Philadelphia as the preeminent model for managing stormwater through green infrastructure” Pennsyvalnia Env. Council

  20. “A Zero Waste Approach to Water ” To develop an integrated water strategy for Ireland we need: • Innovative thinking • Sustainable and resilient technologies • Education curricula reform • Co-ordinated Government and Community Action • Appreciation of rainwater and wastewater as a valuable resource • Design Water In rather than Water Out

  21. Reduce, Reuse and Recycle Pilot StudiesFuture Design - Water In rather than Water Out • Best International Practice • Innovations in Rainwater Harvesting • New build versus retrofit • Water Quality and Quantity • Evaluate Cost Benefits to the Consumer and Producer • Barriers and Incentives • Vocational Training • Guidelines & Technical Standards • Monitoring and Evaluation

  22. Water / Wastewater in Gaeltacht Regions • Appropriate Resilient Technologies for • Water / Wastewater Treatment, Conservation and Reuse • Meeting peak demands from tourism • Island supply • Vocational training • Job creation • Monitoring and Evaluation
