High quality services of wastewater treatment require a continuous assessment and improvement of the technical, environmental and economic performance. This paper demonstrates a comprehensive approach for benchmarking wastewater treatment plants (WWTPs), using performance indicators (PIs) and indices (PXs), in a

The aim of this paper is to present a comprehensive approach for spatial and temporal demand profiling in water distribution systems. Multiple linear regression models for estimating network design parameters and decision trees for predicting daily demand patterns are presented. Proposed approach is a four-step procedure: data collection, data processing, data characterization, and spatial and temporal demand profiling. Continuous flow measurements and infrastructure and billing data were collected from a large set of water network areas and combined with census data. Main results indicate that family structures (i.e., families with elderly or adolescents), individuals

Many national and regional administrations are currently facing challenges to ensure long-term sustainability of urban water services, as infrastructures continue to accumulate alarming levels of deferred maintenance and rehabilitation. The infrastructure value index (IVI) has proven to be an effective tool to support long-term planning, in particular by facilitating the ability to communicate and to create awareness. It is given by the ratio between current value of an infrastructure and its replacement cost. Current value is commonly estimated according to an asset-oriented approach, which is based on the concept of useful life of individual components. The standard values assumed for the useful lives can vary significantly, which leads to valuations that are just as different. Furthermore, with water companies increasingly focused on the customer, effective service-centric asset management is essential now more than ever. This paper shows results of on-going research work, which aims to explore a service-oriented approach for assessing the IVI. The paper presents the fundamentals underlying this approach, discusses and compares results obtained from both perspectives and points to challenges that still need to be addressed.

Chlorine decay modeling in drinking water transport and distribution systems is a major tool for the management of disinfectant concentration. For such purposes, the models to be used in water quality simulators must describe chlorine decay in the systems as accurately as possible, requiring a minimum number of parameters and still be sufficiently robust to predict chlorine residuals under changing operational conditions. In this paper, two second-order decay models (single reactant and two reactants) were examined for their ability to predict chlorine residuals in surface raw and treated waters at a range of initial chlorine and natural organic matter concentrations. The two reactants model is necessary for chlorine residuals prediction in raw waters. However, for treated waters it only performed marginally better than the simpler single reactant model, with half the number of parameters that needed to be estimated. In addition, correlations were observed between both models parameters for reactive natural organic matter (NOM) concentration and measured fluorescence and ultraviolet (UV) spectroscopic data associated with humic-like compounds. Such findings are likely to open the door for a more exact determination of the models

On line monitoring programs based on spectroscopy have a high application potential for the detection of hazardous wastewater discharges in sewer systems. Wastewater hydraulics poses a challenge for in situ spectroscopy, especially when the system includes storm water connections leading to rapid changes in water depth, velocity and in the water quality matrix. Thus, there is a need to optimize and fix the location of in situ instruments, limiting their availability for calibration. In this context, the development of calibration models on bench spectrophotometers, to estimate wastewater quality parameters from spectra acquired in in situ instruments, could be very useful. However, spectra contain information not only from the samples but also from the spectrophotometer, generally invalidating this approach. The use of calibration transfer methods is a promising solution to this problem. In this study, calibration models were developed using interval partial least squares (iPLS), for the estimation of total suspended solids (TSS) and chemical oxygen demand (COD) in sewage from ultraviolet-visible spectra acquired in a bench scanning spectrophotometer. The feasibility of calibration transfer to a submersible, diode array equipment, to be subsequently operated in situ, was assessed using three procedures: slope and bias correction (SBC); single wavelength standardization (SWS) on mean spectra; and local centering (LC). The results showed that SBC was the most adequate for the available data, adding insignificant error to the base model estimates. Single wavelength standardization was a close second best, potentially more robust, and independent of the base iPLS model. Local centering was shown to be inadequate for the samples and instruments used.

The purpose of this paper is to present a simple yet highly effective method to reconstruct missing data in flow time series. The presence of missing values in network flow data severely restricts their use for an adequate management of billing systems and for network operation. Despite significant technology improvements, missing values are frequent due to metering, data acquisition and storage issues. The proposed method is based on a weighted function for forecast and backcast obtained from existing time series models that accommodate multiple seasonality. A comprehensive set of tests were run to demonstrate the effectiveness of this new method and results indicated that a model for flow data reconstruction should incorporate daily and seasonal components for more accurate predictions, the window size used for forecast and backcast should range between 1 and 4 weeks, and the use of two disjoint training sets to generate flow predictions is more robust to detect anomalous events than other existing methods. Results obtained for flow data reconstruction provide evidence of the effectiveness of the proposed approach.

Advances in measurement and automation technologies enabled the deployment of monitoring systems with data acquisition at high frequency in Wastewater Treatment Plants (WWTP). The aim of this work is the design of soft sensors to predict hard-to-measure quality variables of wastewater required for mechanistic modeling of the biological treatment system in a real municipal WWTP. The input data collected in the WWTP using a flowmeter and spectro-photometric and electrochemical online probes, sampling campaigns and on-line analysis, was used for the development of soft sensors by multivariate analysis, like Principal Component Analysis (PCA) and Partial Least Squares (PLS) regression. Exploratory data analysis was performed in order to detect outliers, patterns and correlations. PLS models for soft sensors were developed using leave-one-out cross validation and the predictive capacity of independent data was evaluated by root mean square error (RMSE). The normalized RMSE obtained for organic nitrogen prediction were 19.5% and 18.1%, using sensors with analytical and spectral data, respectively. The possibility of using spectro-photometric probes providing measurements of a single wavelength was evalu-ated in order to reduce the online monitoring investment costs.

It is expected that, in Europe, by 2030, and in the context of climate change, water stress and scarcity will affect around half of the river basins. The buildings sector is among the top priorities in terms of efficient use of resources in the EU. Water saving potentials of 30-50 % may be estimated for buildings. Office buildings in particular present a significant potential as they are, by nature, large water consumers.

À medida que a produção de águas residuais aumenta e os efeitos das alterações climáticas se intensificam, a sustentabilidade do tratamento de águas residuais torna-se uma questão mais premente. À luz da proposta de revisão da Diretiva das Águas Residuais Urbanas (DARU), em aprovação, que impõe a neutralidade energética até 2045, com várias metas intercalares, denota-se uma mudança de paradigma. Tal implica a avaliação do impacto climático das Estações de Tratamento de Águas Residuais (ETAR), de modo a desenvolver estratégias eficientes para os serviços urbanos de água residual em Portugal. Assim sendo, analisou-se o panorama nacional relativo ao consumo de energia e às emissões de Gases de Efeito de Estufa (GEE) do tratamento de águas residuais, entre 2018 e 2022. A metodologia incluiu a avaliação do consumo e da autonomia energética e das emissões diretas (processo de tratamento) e indiretas (consumo de eletricidade) de GEE. Os resultados permitiram identificar as tendências destes serviços e o seu alinhamento com as metas propostas a nível europeu e nacional. É importante compreender e mitigar as emissões de GEE em ETAR, e em atividades da sociedade em geral, para garantir um futuro sustentável para as gerações vindouras.

Urban water systems are essential for public health, quality of life, and urban sustainability. Despite the progress in the last decades in managing wastewater and rainwater in urban areas, challenges persist and are exacerbated by climate changes. Existing urbanisation and infrastructure systems are valuable assets and ultimately are barriers to urban sustainability transition, including the type of drainage systems and their condition. New paradigms should act as drivers for change, incorporating these into new solutions while providing multiple benefits not limited to drainage.

Urban water systems are essential infrastructures for urban sustainability. According to the International Energy Agency (IEA), the water sector uses 4% of the energy worldwide. The energy cost for wastewater and water supply systems is 30%-40% (IEA, 2019) of the energy global spending. These authors expect the energy consumption in the water sector to double by 2040. Influencing factors for this rise are the increasing use of desalination and higher coverage in wastewater treatment (IEA, 2016). The water supply and wastewater sectors are energy intensive and have a substantial energy footprint. Water utilities typically manage the services in these sectors, including the water supply and wastewater systems. Emissions from these utilities

A evolução da legislação europeia, em termos de micropoluentes, é reflexo das preocupações crescentes com um número cada vez mais vasto de contaminantes de interesse/preocupação emergente (CEC) (Yang et al. 2017), tendo começado por maior exigência na sua monitorização e, mais recentemente, de tratamento (Rosa et al. 2023a). Exemplo disso é a nova diretiva de tratamento de águas residuais (DARU ou UWWTD, em inglês), a ser publicada este ano, a qual exigirá um tratamento adicional (quaternário) nas ETAR que permita 80% de remoção de uma lista de substâncias indicadoras de micropoluentes para todas as ETAR acima de 150.000 p.e. (implementação faseada) e para as ETAR acima de 10.000 p.e. selecionadas com base numa avaliação do risco. A nova Diretiva coloca múltiplos desafios, com maiores exigências também ao nível de controlo de nutrientes e metas de neutralidade energética.

A nova diretiva europeia de tratamento de águas residuais urbanas, que se espera seja aprovada ainda este ano, vai exigir a remoção de micropoluentes orgânicos (compostos farmacêuticos e agentes anticorrosão) em muitas estações de tratamento de águas residuais (ETAR) urbanas. No âmbito do projeto LIFE Fitting (2023-2025) está a ser desenvolvida, entre outras, uma ferramenta para previsão e otimização da remoção destes micropoluentes em ETAR urbanas - CEC ForecasTool. O desenvolvimento da ferramenta assenta em caraterísticas chave dos compostos, determinantes da sua biodegradabilidade e reatividade com ozono, uma das tecnologias consolidadas para a sua remoção, e em condições-chave de operação das ETAR, que estão a ser testadas de forma controlada em três grandes ETAR de Portugal com forte contributo industrial e/ou hospitalar. Nos últimos meses, têm sido desenvolvidas campanhas para teste da razão alimento/microrganismo (F/M), para comparação de condições de nitrificação e de tipos distintos de sistemas de lamas ativadas e de arejamento, bem como de doses normalizadas de ozono. No âmbito desta comunicação, serão apresentados os principais resultados obtidos para o desenvolvimento/validação da ferramenta CEC ForecasTool.

Com base na respetiva visão e missão, a organização deve: estabelecer objetivos e metas estratégicos, efetuar a avaliação e diagnóstico quanto ao cumprimento dos objetivos, comparar com as metas definidas, identificar oportunidades de melhoria, selecionar e priorizar alternativas, acompanhar a implementação, e monitorizar e rever o plano.

O Guia Técnico n.º 27 concretiza a 4.ª geração do sistema de avaliação da qualidade dos serviços da ERSAR, sendo o resultado de um excelente exemplo de colaboração entre a ERSAR, enquanto entidade reguladora, o Laboratório Nacional de Engenharia Civil e a Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa, a quem não podíamos deixar de agradecer, alargando este agradecimento ao universo das entidades gestoras reguladas, cujos contributos prestados durante a consulta ao setor foram integrados nesta versão final.

The European project LIFE IMPETUS demonstrated low-investment, low-energy, flexible, and easy to implement measures for improving the removal of pharmaceutical compounds in urban wastewater treatment plants (WWTPs) with activated sludge (CAS) treatment, the most common biological process in those plants in Portugal and worldwide.The project addressed two major groups of technical solutions: i) operating strategies to enhance the biological treatment for PhC removal, measures identified using sound benchmarking tools, and ii) powdered activated carbon (PAC) addition to the biological reactor, using eco-friendly adsorbents, to control the recalcitrant PhCs and those with incomplete and variable biological removal. These technical guidelines compile the best practices and best lessons learned in LIFE IMPETUS project regarding PhC monitoring and improvement of PhC control in urban CAS-WWTPs using the approached technical solutions. The document aims at an easy and comprehensive use by water practitioners, water regulators, academia, and students of different backgrounds, answering to the questions of what, where, how, how much (cost), and when to monitor and control PhCs in urban CAS-WWTPs. Incentives for PhC control in urban WWTPs are also tackled.

The Technical Guide presents the 4th generation of the service quality assessment system, which abandons some 3rd generation indicators and adds new ones to respond to the latest challenges to supply services, urban waste water management and urban waste management. Changes are also made to definitions and benchmarks for some indicators are adjusted.

Asset management (AM) has become increasingly important in various sectors and organizations over the lastfew decades. This introductory chapter provides an overview of asset management to facilitate a comprehensive understanding of AM, summarizing its application to urban drainage asset management (UDAM), an asset-intensive sector. The chapter includes a short history, from general AM to UDAM, and refers to milestones, key organizations, and standards. It describes AM principles and different perspectives to approach the subject. The UDAM context is outlined, providing the general processes which can influence strategic, tactical, or operational decision levels, accounting for the specific perspectives and objectives on the subject. The main approaches applied to UDAM are broadly described, some of which incorporate a balance of costs, risks, opportunities, and performance, while others focus on specific aspects. The chapter presents different types of approaches to AM, ranging from those based on condition, reliability, and risk to those based on value, followed by those based on performance or quality of service, highlighting common aspects or overlaps between them. When appropriate, guidance to the chapters where additional information on the subject can be found is provided. Finally, challenges, limitations and opportunities are highlighted.

The number of climate-related disasters has progressively increased in the last two decades and this trend will drastically exacerbate in the medium- and long-term horizons according to climate change projections. In this framework, through a multi-disciplinary team and a strong background acquired in recent projects, ICARIA aims to promote the use of asset-level modeling to achieve a better understanding of climate related tangible direct and indirect impacts on critical assets due to complex, cascading, and compound disasters. Furthermore, it takes into account the related risk reduction provided by suitable, sustainable, and cost-effective adaptation solutions. ICARIA focuses on both (i) critical assets and services that were not designed for potential climate change-related impacts that can increase the unplanned outages and failures, and (ii) on housing, natural areas, and population. Cutting edge methods regarding climate scenario building, asset-level-coupled models, and multi-risk assessment approaches will be implemented and replicated in three EU regions to understand how future climate scenarios might affect critical assets and to provide decision-making support tools to private and public risk owners to assess the costs and benefits of various adaptation solutions.

Activated carbons are versatile adsorbents that can play a crucial role in the enhancement of wastewater treatment, namely by controlling organic microcontaminants of emerging concern (CECs) and organic matter. These materials have a 100-year market availability, large scientific testing at lab-scale and applicability in consolidated technologies. However, the use of activated carbons at full-scale wastewater treatment is still emerging, driven by the increasing awareness on environmental and human threats mainly resulting from CECs. The present chapter reviews the literature on the application of activated carbons in full- or large pilot-scale plants, highlighting the state-of-art knowledge on practical issues on operational set-ups, improvements on water overall quality, and costs. The selection criteria and properties of the powdered and granular (PAC and GAC) materials used, and the pros and critical aspects of their application, relevant for product development and process optimisation, are also analysed and determine the research needs proposed for a technical, economic, and environmentally sustainable application of activated carbon in full-scale advanced wastewater treatment.

Urban areas are dynamic, complex, and vulnerable systems involving multiple strategic services such as water supply, wastewater, and stormwater and waste management. Climate-change trends may directly affect the urban water cycle, through heavy rainfall, tides, and droughts, potentially causing cascading impacts with serious consequences for people, the natural and built environments, and the economy. These challenges to urban areas require an integrated and sustainable approach to increase their resilience, with the allocation of the needed resources, including the development and implementation of disaster risk reduction (DRR) strategies, plans, and regulations in all relevant sectors. This chapter describes a resilience-assessment framework to be used by cities and urban-service managers. It considers a structured and objective-driven assessment aiming at supporting the development and monitoring of cities' and urban services' resilience action plans, thus contributing to appropriate DRR investments. Our approach considers four resilience dimensions: organizational, spatial, functional, and physical. It is aligned with the UNDRR's Disaster Resilience Scorecard for Cities and addresses the priorities of the Sendai Framework for Disaster Risk Reduction. In this chapter, we apply the resilience-assessment framework to the waste and mobility sectors in Lisbon (Portugal), identifying main opportunities to enhance their resilience and supporting the development of resilience and DRR strategies.

Atualmente os sistemas urbanos de água são reconhecidos como infraestruturas in­dispensáveis de suporte para a prestação de serviços públicos de primeira necessida­de à saúde e bem-estar das populações e à economia das sociedades

This paper aims to explain why and how innovative technologies are enablers of strategic asset management (SAM) of water supply, wastewater and storm water systems.

Urban areas are dynamic, complex, and vulnerable systems involving multiple strategic urban services, stakeholders, and citizens. Strategic services essential to society include water and sewerage (water supply, and wastewater and stormwater management), waste management, energy supply, public lighting, transport, and public security. The potential effects of climate dynamics on the urban areas might lead to the aggravation of existing fragile conditions and the emergence of new hazards or risk factors, with major impacts on strategic urban services, people, the natural and built environment, and the economy. Climate change challenges to urban areas thus require an integrated and sustainable approach to increase their resilience, with the allocation of the needed resources at all administrative levels. These include the development and implementation of disaster risk reduction (DRR) strategies, policies, plans, laws, and regulations in all relevant sectors (UNISDR, 2015). This chapter describes a resilience assessment framework to be used by cities and urban-service managers. The framework considers a structured and objective-driven assessment aiming at supporting the development and monitoring of cities

This chapter briefly presents concepts and methodologies to support the management of urban drainage infrastructure. After the introduction, data requirements for assessing the condition of urban drainage systems are presented. Data can be collected in different ways. Data analysis allows for determining structural and functional issues and system performance. The causes and consequences of failures are required for condition assessment and are the subject of the risk section. Any intervention in the urban drainage system has a cost that must be assessed. Mathematical modelling of the urban drainage systems has an advantage for evaluating the hydraulic and structural performance. Decisions on the management of urban drainage rehabilitation need to be addressed considering the different points of view or aspects that are often contradictory. This may be addressed by using multi-criteria decision analysis methodologies.

Urban water services make use of extensive networked infrastructures - water supply and drainage systems. Efficient management of these services relies on the quality of measurements of hydraulic variables in pipes and sewers to support robust analysis of systems

Exhaustive climate hazard identification was performed for Barcelona, Lisbon and Bristol in order to properly drive the research about possible climate change impacts on their urban areas. In particular, past climatic trends and future projections were examined according to previous studies. Climate change drivers and their related climate variables were evaluated taking into account several risk matrixes. Therefore, a level of importance was proposed for each climate variable for ordering priority and efforts in the climate module (Work Package 1) of the RESCCUE project.Once identified all climate variables, data collection was performed for the three cities. CMIP5 data and observed data were considered for both atmospheric and oceanic variables. Climate change simulations, decadal outputs and seasonal models have been collected for the project. For the observed variables, the greatest database collected consists of temperature, precipitation, humidity, pressure, wave height and tide.Before the beginning of the study about the climate change in the studied areas, we have carried out an analysis of the provided observed data in those areas to ensure that the quality of those data is good enough for subsequent studies and conclusions. For this purpose, a set of tests were applied over all time series: general consistency, outliers and inhomogeneities. The results of the tests showed an acceptable quality for most of the datasets.
