“…Table 2 presents the overall results obtained by applying the environmental impact indicators to the four studied plants. The results show a similar order of magnitude to those reported by Amores et al, (2013) and Ribera et al (2014) in terms of the application of aluminum sulfate and chlorine gas to the drinking water process. It can also be observed that PLA-BOS has the highest impact of all of the environmental impacts studied.…”

There is currently great concern about the processes that directly or indirectly contribute to the potential for global warming, such as stratospheric ozone depletion or acidification. In this context, and provided that treated water is a basic public utility in urban centers around the world as well as in some rural areas, its impact on the environment is of great interest. Therefore, this study applied the environmental methodology of Life Cycle Assessment (LCA) to evaluate the environmental loads of four potable water treatment plants (PWTPs) located in northeastern Colombia following the international guidelines delineated in ISO 14040. The different stages of the drinking water process were thoroughly assessed, from the catchment point through pumping to the distribution network. The functional unit was defined as 1 m 3 of drinking water produced at the plant. The data were analyzed through the database Ecoinvent v.3.01, and modeled and processed in the software LCA-Data Manager. The results showed that in plants PLA-CA and PLA-PO, the flocculation process has the highest environmental load, which is mostly attributable to the coagulant agent, with a range between 47-73% of the total impact. In plants PLA-TON and PLA-BOS, electricity consumption was identified as the greatest impact source, with percentages ranging from 67 to 85%. Treatment processes and techniques, bioclimatic conditions and culturally driven consumption behavior varied from region to region. Furthermore, changes in treatment processes and techniques are likely to affect the environment during all stages of a plant's operational cycle.Keywords: climate change, environmental impact, treated water. Avaliação do ciclo de vida de quatro estações de tratamento de água potável localizado no nordeste da Colômbia RESUMO Atualmente, existe uma grande preocupação com os processos que direta ou indiretamente contribuem para as alterações climáticas, destruição da camada de ozônio ou acidificação, entre outros impactos ambientais. Neste contexto, e desde que a água tratada constitui um serviço público básico em centros urbanos de todo o mundo e em algumas áreas rurais, o impacto de suas emissões no meio ambiente tem sido considerado de grande interesse. Assim, na pesquisa atual foi aplicada a metodologia ambiental de avaliação do ciclo da vida (LCA) para avaliar os impactos ambientais de quatro estações de tratamento de água potável (PWTPs), localizadas no nordeste da Colômbia seguindo diretrizes internacionais da ISO 14040. As diferentes etapas do processo de purificação a partir do ponto de captação por meio de bombeamento para a rede de distribuição foram completamente avaliadas. A unidade funcional foi definida como 1 m 3 de água potável produzida na fábrica. Os dados foram analisados com base no banco de dados Ecoinvent v.3.01 e processados no software LCAData Manager. Os resultados possibilitaram determinar que em plantas PLA-CA e PLA -POR, o processo de floculação tem a maior carga ambiental, o que é principalmente atribuível ao agente ...

“…Water companies are currently facing challenges, because social responsibility must be a constant concern in the development of their economic activity, increasing business competitiveness and achieving the collective well-being, while on the other hand, face severe constraints of water as resource, which is scarce for endless needs. This justifies the knowledge of the reality of the bottled water sector companies, which depends on water as a natural resource (Amores, Meneses, Pasqualino, Anton & Anton, 2013). It is essential that companies respond to these challenges in an innovative way, allowing the efficiency and effectiveness of their business activities, and help to maintain and improve natural, social and financial resources (Lozano, 2011;Rifkin, 2014;Srivastava & Statler, 2012).…”

The aim of this research is assessment of the relationship between the adoption of social responsibility practices and the performance of the water sector companies. The complexity of challenges in the water sector means that innovative solutions are required, in the manner businesses are conducted and operated. In order to integrate sustainability into business companies, this investigation identifies performance indicators that recognise the main difficulties facing the water industry and contributes to define strategies sustainability for these companies, since the water market and the inherent value of water as a public good embrace all stakeholders. On the other hand, the financial crisis introduces in society, in general, the demand for greater interest on practices of Corporate Social Responsibility (CSR); for this reason, the authors defend the implementation of CSR strategies to get sustainable success in the water sector.

“…The LCA results of Kunshan WWTP taking renewable energy (wind power) as the energy source proposed that enhancing the effluent quality will decrease the environmental impact [18]. Amores et al [19] empltoyed the Life Cycle Assessment methodology to carry out an environmental analysis of every stage of the urban water cycle in Tarragona, a Mediterranean city of Spain, taking into account a water supply system of a city considering water abstraction, potable water treatment, distribution network, wastewater treatment, reclaimed water, and desalination. They compared three scenarios: 1) current situation, 2) using reclaimed water and using desalination plants, 3) reclaimed water to supply water during a drought.…”
