Institutional capacity for implementing integrated water management should be reviewed and developed when there is a clear demand.Existing administrative structures will often be quite capable of achieving local water resources management,but the need may arise for new institutions based upon the perspective,for example,of river catchment areas,district development councils and local community committees.Although water is managed at various levels in the socio-political system,demand-driven management requires the development of water-related institutions at appropriate levels,taking into account the need for integration with land-use management

Re-inventing America's Urban Water Infrastructure in 2011 Re-inventing America's search Urban Water Infrastructure LOCIN A National Science Foundation ERC WELCOME PEOPLE RESEARCH EDUCATION INDUSTRY BLOG CONTACT Research Jorg Drewes,Research Director Our research program focuses on fundamental investigations and applied research to create a suite of successful water management options and decision-making tools.We study engineered and natural systems and the way in which they can be effectively integrated into the portfolio of urban water resources. Some specific aims of this research are: To incorporate resource recovery and energy production into engineered water systems To engineer natural systems to improve water quantity,water quality,and habitat, To overcome impediments to adopting new urban water management strategies, To develop technologies in concert with companies involved in the Center's program, To provide improved decision-making tools to decision makers. Our fundamental research on engineered and natural systems will inform our water c7 supply portfolio testbeds,which in turn will help us reinvent urban water systems. achieve a Resiliency
