Purpose and themesReclaimed water is of fundamental importance to our environment and economy. Planned, more direct use of reclaimed water contributes to an efficient and more reliable use of the water resources. It enables to reduce the impact of water shortage due to population growth or drought. At the same time it decreases the impact of human activities on the fresh water resources. Conference purposeWater reuse is no longer restricted to water scarce areas. In fact it is becoming an essential component to increase the water supply reliability, both in quantity and quality, and to comply to increasing environmental standards. Today, the framework of integrated water management offers unique opportunities for water reclamation and reuse to be implemented on a larger scale as a sustainable practice. Now is the time to consolidate and improve our methodologies and technologies in order to better recognize the benefits of reuse and to enhance the implementation of water reuse schemes. This conference will provide an excellent environment to exchange experiences in water reuse from dry and wet climate areas, from industrialised and rural areas, from high and low income countries. Issues at the centre of debate will cover risk management, financing, water quality, use of high tech versus low tech, water reclamation in industry, sustainable irrigation practices using reclaimed water and water reclamation in urban water supply. Conference themesThe conference themes are grouped into 3 main tracks: Rationale for sustainable water reuseThis track covers latest ideas and experiences in establishing a rational wastewater reuse strategy in the context of sustainable water governance. It compares the merits of water reuse with regards to other measures to reach an efficient use of water resources of the water cycle. It looks at means to provide an adequate driver (legislative or otherwise) to foster and promote the use of reclaimed water whenever appropriate. Themes in this track include but are not limited to: Economic benefits of water reuse (internalities or externalities) Sustainable cost recovery Health risks Policy and regulations Liability and water rights Implementation of the precautionary principle Institutional arrangements, including ownership ... Demand management Stakeholder involvement and public acceptance Comparison with alternative water resources (desalination ...) The role of decentralised water reuse systems Direct vs indirect potable reuse Ethics
up Advanced water reclamation techniquesThis track covers novelties and advances (e.g. improvement of technological reliability and cost reduction) in existing water reclamation techniques. Themes in this track include but are not limited to: Natural reclamation technology (lagoons, soil-aquifer treatment and storage, constructed wetlands …) High-tech reclamation technology (MBR, MF, UF, RO, ozone …) Combination of high-tech / natural reclamation technology Advances in disinfection Water quality: measuring, ensuring, interpreting; from discovery to standards Reclamation techniques for decentralised water reuse Techniques for on-site recycling of industrial process water Biofilm control and other advances in reclaimed water distribution systems
up Implementation and operation of water reuse schemesThis track covers experiences, preferences and trends in the implementation and operation of water reuse schemes. It looks at best practice at project level, case studies showing positive experiences in the field, with the existing local constraints in project implementation as a boundary condition. Themes in this track include but are not limited to: End-use requirements beyond regulation Safety requirements and operational reliability Process instrumentation, control and automation Failure and failure management
