Outline

The project "Sustainable Water and Wastewater Management in Urban Growth Centres Coping with Climate Change − Concepts for Lima Metropolitana (Perú) (LiWa)" aims at the sustainable planning and management of one of the crucial lifelines − water and sanitation. This will be done in one of the urban growth centres of the world, Lima, with particularly adverse boundary conditions. The project draws particular attention to the impacts of climate change on and the promotion of energy efficiency in water and sanitation systems.

Within the LiWa-project, fundamental procedures and tools for participatory decision making will be developed and applied based on informed decisions. The project builds upon the modelling and simulation of water supply and sanitation in the entire urban growth centre system of Lima. Furthermore, the project analyses options for redesigning the water tariff system to meet economic, ecologic and social requirements. With this approach, key issues and challenges of energy- and climate-efficient structures of water and wastewater management will be adequately addressed.

Research at the UFZ focuses on the identification and evaluation of water pricing options that promise to overcome water quality and quantity problems in Lima. It will be analysed how well different options are able to recover the costs of water supply, meet distributional goals and overcome institutional and political-economical obstacles. Moreover, light will be shed on possible changes of the institutional framework, which may be necessary to implement a pricing reform.
