“…Mediante o exposto, a escolha da configuração de tratamento se justifica pela representação da concepção mais comum no País e por apresentar um quantitativo de ETEs na Bacia do Rio Cocó que viabilizou a exibição da metodologia e dos resultados obtidos no formato do presente periódico. Na Tabela 1 estão Bezerra et al (2019) pontuam que indicadores de desempenho (IDs) são capazes de possibilitar uma visão abrangente, de modo a se obter avaliações consistentes sobre o desempenho de diferentes serviços. A sua quantificação pode impulsionar bastante os processos de tomada de decisão, uma vez que permitem a identificação de problemas e a consequente promoção de medidas corretivas, além de apoiarem à formulação de ações, políticas e estratégias mais eficientes.…”

As estações de tratamento de esgotos são consideradas fontes pontuais de poluição, podendo ocasionar o comprometimento dos corpos hídricos receptores. O desempenho eficaz e eficiente das ETEs contribui para a gestão sustentável dos recursos hídricos. Neste estudo, indicadores de desempenho (IDs) mais relevantes para a avaliação do desempenho de ETEs de uma bacia de esgotamento no município de Fortaleza, Ceará, Brasil, foram selecionados e analisados com base nas opiniões de especialistas. As respostas obtidas por meio do método Delphi foram utilizadas para definir os pesos dos IDs, utilizando o método AHP. Dos 18 IDs selecionados, destacaram-se: “Remoção de carga poluente do esgoto afluente na estação de tratamento”, “Conformidade das análises de esgoto tratado para sólidos suspensos totais” e “Conformidade das análises de esgoto tratado para DBO”. Em seguida, os desempenhos globais de 3 ETEs da área de estudo foram determinados pelo método multicritério TOPSIS-Sort. As ETEs Aldemir Martins e José Euclides obtiveram desempenho “Insatisfatório”, enquanto a ETE Castelão obteve “Satisfatório”. Espera-se que os IDs estruturados neste estudo sejam utilizados pelos atores envolvidos no processo de tomada de decisão, bem como a metodologia desenvolvida possa ser aplicada em outros estudos, considerando suas características e condições locais.

“…Being one of the core topics of the United Nations' Sustainable Development Goals (SDG), nowadays drinking water is recognized worldwide as an essential resource, however vulnerable, limited and increasingly scarce, a situation which is impaired by factors such as increase in demand, pollution of water sources and increasingly severe climate changes (GOONETILLEKE & VITHANAGE, 2017;BEZERRA, PERTEL & MACÊDO, 2019). For McDonald et al (2014) such a scenario is also the result of strong global urbanization movement without the necessary planning, related to water availability in the surroundings of cities to supply water to the populations, as well as to the management of residues produced by such cities.…”

In concerns of non-revenue water in water supply systems, the benefits arising from the reduction of their indexes directly impact social, economic and environmental spheres, including the expansion of access to clean water. Benchmarking is a management tool already adopted by some countries in this context, aiming to reduce the amount of non-revenue water. The present study aimed to gather information about the application models of this tool, as well as to compare the performance with other countries in which it is also not applied. It was observed that the ideal benchmarking structuring model capable of minimizing these indexes includes less than annual application frequency, partial regulation, absence of confidentiality, gratuity, open and restricted reports to service providers and mean interactivity of the results release. It was also concluded that the countries where benchmarking is practiced have better performances regarding lower levels of non-revenue water.

MARQUES, L.O.A. Digital benchmarking platform for loss control in water supply systems. Dissertation submitted to the School of Engineering of São Carlos, University of São Paulo, in order to obtain the title of Master of Science in Hydraulic Engineering and Sanitation. São Carlos, 2021.Brazil is a country that still lacks adequate water treatment and sanitation services for its population. The high levels of water losses, recently highlighted in the new Brazilian Law 14.026/2020 for the sector, make tariffs more expensive, which could make access to these services difficult. It can also damage the water resources, demanding from them much more than what is required for the population's consumption. Currently, water losses in Brazil are approximately 40%. This represents billions of reais being wasted every year due to the inefficiency of current water systems, which makes it urgent to adopt management measures that can minimize these rates. Benchmarking is a management tool adopted by many countries in their water supply systems. This practice allows that, through the comparison between processes and key performance indicators from water utilities, there is an improvement in the performance of these organizations, improving the services offered to the population. The practice is even regulated by the current legislation in some of these locations. Its effective application in the water industry in Brazil requires development of more accessible tools, especially those with low cost and operational ease. In addition, it is necessary to strengthen the perception of the importance of the benchmarking process with water utilities and regulatory agencies, highlighting gains in transparency and credibility resulting from its use. Thus, this research aimed to develop a digital benchmarking platform to control losses in water supply systems. To this end, an executive project was planned, divided into three stages, with a pre-project and five modules of research and development activities. This project was made in a participatory way, with evaluations from potential users of its functional aspects such as ease and interactivity. It was possible to obtain a dynamic tool containing indicators of water losses and which makes it possible to compare the practices to combat losses adopted by water utilities in the hydrographic basins of the Piracicaba, Capivari and Jundiaí rivers. The final version of the benchmarking platform was submitted for product registration and will later be made available free of charge to service providers in the region to be used to avoid water losses and on the University of São Paulo website, as a support for researchers.
