Descrição

Mestrado em Engenharia do Ambiente - Tecnologias Ambientais - Instituto Superior de Agronomia TheEarth's water resourcesare limited and its availabilityisnotgeographicallyevenlydistributed.Only1% of all existing water is fresh waterandistherefore likely tobe usedfor human consumption. To achieve environment sustainability, it is essential the protection of complex ecosystems and the wise use of natural resources; our survival could depend on this. Sustainability cannot be achieved with current models of consumption and the disproportionate use of resources. One solution to this problem is the use of systems for storage and reuse of treated wastewater. In this thesis, the case study focuses on demonstrating the economic viability of building, on the surroundings of the Station of Wastewater Treatment at the community of Fernão Ferro, of a supplying Unit of treated wastewater to be used in tanks, pump trucks, mechanical sweepers and similar equipment, and also to supply the irrigation networks already installed in this community.Thus, considering that the present project aims to increase the life of the treated effluent, it was performed, in the experimental part of this thesis, the calculation for the study’s financial feasibility; it allowed us to conclude that the project is feasible through an application of the National Strategic Reference Framework, 2007/2013 (QREN - Quadro de ReferênciaEstratégicoNacional), that could subsidy 80% of the total investment, and the remaining 20% would be supported by the Seixal township
