This paper presents and demonstrates a novel scenario-building methodology that integrates contextual and future time uncertainty into the performance assessment of water distribution networks (WDNs). A three-step approach is proposed: (i) System context analysis, identifying the main key factors that impact the WDN performance; (ii) Scenario definition, identifying the implicated WDN variables, describing its possible evolution, and conjugating them to further establish the reference scenario and the two most relevant and opposite ones; and (iii) Scenario modelling, simulating the WDN behaviour for those scenarios. The obtained spatial and temporal hydraulic results are further used to calculate performance metrics. The methodology is applied to a real WDN to assess resilience performance considering infrastructure asset robustness (real water loss performance indicator), service reliability (minimum pressure index), and service flexibility (network resilience index). A new formulation to assess the metric evolution over time is proposed, deducting the further-away performance results by using an uncertainty weight. The results demonstrate that the increase in metric amplitude for the opposite scenarios over time highlights future uncertainty, reflecting context uncertainty, and the comparison of metric spatial distribution (i.e., at the pipe/node levels) highlights critical areas with higher associated uncertainty.

Modeling sanitary sewer overflow (SSO) discharges based on flows measured at pumping stations presents specific challenges distinct from modeling combined sewer overflow (CSO) discharges and is insufficiently studied. This paper presents a methodology aimed at reducing and assessing the uncertainty in SSO estimation. Four lumped models are compared: a time

In regions with a strong seasonal or interannual asymmetry in the distribution of precipitation and higher frequency of droughts, collective irrigation systems are vital infrastructures for agricultural activity. Although operating for decades, several systems have ageing infrastructures, with relevant water losses and pumping energy inefficiencies. Consequently, the systems are not adequately designed or operated to meet current and future water demand. Therefore, rehabilitation to improve water and energy efficiency while ensuring infrastructure, economic sustainability and service quality is crucial. In this sense, comprehensive approaches using performance assessment to support the planning process or benchmarking between water users associations play an essential role in improving efficiency in collective irrigation systems.

Many collective irrigation systems have been operating for decades, facing high degradation of existing infrastructures and huge water-energy efficiency problems. Predominantly composed of open canals, they have been partially or entirely converted into pressurised pipe systems, implying a considerable increase in energy consumption and operation and maintenance costs. Simple, easy-to-use, and comprehensive approaches for energy efficiency assessment in collective irrigation systems are needed for diagnosis and assisting decision-making on implementing adequate improvement measures. This research proposes and demonstrates an innovative approach based on the water and energy balances and performance indicators to assess the effect of water losses, network layout and operation, energy recovery, and equipment on energy efficiency. A novel methodology for energy balance calculation is proposed for open canal, pressurised and combined systems. The application to a real-life open canal system and network areas allowed the identification of efficiency problems mainly due to water losses in canals, followed by the dissipated energy in friction losses. Less critical are pumping and manoeuvring equipment inefficiencies. Also, a considerable excess of gravity energy is recovered in hydropower plants. In raising pipe systems, in which shaft input energy predominates and costs for pumping play a key role, surplus and dissipated energy in friction losses are the most relevant issues. Significant energy is lost in the water conveyance and distribution in both systems. Consequently, the potential to improve energy efficiency through water loss management, network layout, and operation improvement, besides pumping and manoeuvring equipment replacement, is considerable.

This study compares and discusses the adequacy of surrogate resilience metrics proposed in the literature for resilience assessment of drinking water systems concerning demand increase and network redundancy. A sensitivity analysis is carried out for increasing flow rates using a conceptual case study with different layouts and demand scenarios, selecting several metrics to assess the resilience of two real network areas. Resilience metrics based on surplus energy are sensitive to network layout and demand scenarios. The network resilience index considers hydraulic reliability and network diameter uniformity. In contrast, the weighted resilience index also considers the network topology and gives importance to pipes with higher flow rates. Entropy-based resilience metrics mainly rely on the network flows' uniformity and are sensitive to pipe redundancy. The entropy metric most adequate to assess the hydraulic capacity is the diameter-sensitive flow entropy, since it is sensitive to the velocity inside the pipes. Topology metrics cannot assess the hydraulic capacity though evaluate the system redundancy (meshed-ness coefficient), robustness (central-point dominance) and water transportation efficiency (average-path length). Surrogate resilience metrics do not assess the system performance during a failure. They indicate systems which are better prepared to overcome failure events and increased demand events, providing vital information to drinking water systems management.

A global framework to assess the energy use and efficiency in wastewater systems is presented, focusing on the development of a portfolio of energy use improvement measures specifically tailored to these systems. The framework includes a performance assessment system for energy efficiency in wastewater systems and an energy balance scheme. The development and analysis of the portfolio of measures included the following steps: (i) an extensive review and compilation of existing energy improvement measures on the urban water cycle, (ii) a tailored survey addressed to multidisciplinary teams of wastewater utilities, (iii) the consolidation of the portfolio of measures for wastewater systems with the identification of main benefits and drawbacks of each measure and (iv) the discussion of the application of the improvement measures. Results from the survey for the different assessed dimensions (e.g., priority, importance) of each measure are presented together with a specific analysis of wastewater utilities. The final portfolio is instrumental for utilities to select measures, decide on the priority ones and prepare an implementation plan.

Com secas cada vez mais frequentes e prolongadas em Portugal, é necessário repensar medidas que permitam enfrentar a falta de água. A água residual tratada constitui uma fonte de água alternativa, a ser utilizada como água para reutilização (ApR) em usos compatíveis, como rega de espaços verdes e lavagem de ruas.A modelação do decaimento de cloro em Sistemas de Distribuição de ApR (SDApR) carece de estudos que proponham metodologias de implementação dos modelos, técnicas de trabalho experimental a nível laboratorial e exemplos de aplicação à escala real. A modelação contribui para promover uma gestão eficaz da desinfeção da ApR, ajudando a determinar dosagens de desinfetante, concentrações residuais nas redes e locais de cloragem.Neste artigo apresenta-se uma metodologia para modelar o decaimento de cloro em ApR usando o software EPANET-MSX. A metodologia envolveu três fases: desenvolvimento do modelo hidráulico, modelação do decaimento de cloro na água e modelação do decaimento de cloro devido às paredes do reservatório e condutas. O modelo foi aplicado num SDApR da área de Lisboa e calibrado com ensaios à escala real, permitindo simular o decaimento de cloro em diferentes pontos do SDApR ao longo do tempo e prever as necessidades de doseamento de cloro

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 multirisk 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.

This paper investigates the effect of different types of structural and operational measures on water mixing and renewal time in circular and rectangular cross-section water storage tanks, aiming at a better understanding of the flow dynamics to find practicable solutions to improve their design, rehabilitation and operation. An experimental programme, including traditional tracer and dye tracer tests, was carried out in small-scale tanks for different configurations and operating conditions. Two tanks were tested with and without interior structures, with the inlet/outlet pipes at different locations and for constant and variable water level. The main findings are that: i) the most effective measure is operating with fill-and-draw cycles, however, for tanks operated nearly full structural measures are recommendable; ii) reducing the inlet pipe diameter and installing nozzles near the tank bottom improve the mixing conditions; iii) the use of baffles is recommendable when the inlet and outlet pipes are very close.

The constant expansion of urban areas ant its services has created new challenges to city managers. Climate Change (CC) is one of the most important topics, taking special importance in urban areas. Given its scalability, technology can take an important role to help city managers identify and mitigate specific CC-related problems in these areas. In this paper, a web application is presented to empower city managers with a tool that give them detailed data about their cities resilience to cope with CC, accessible from anywhere. The usage of this app allows city managers to take optimized measures to suppress weak areas of each city. This app is integrated as a service of the Portuguese Infrastructures Roadmap, under the Infraestrutura Nacional de Computação Distribuída (INCD) project INCD provides the resources for the apps’ data computation and storage, and assures its scalability to handle multiple user requests as well as database storage growth. This app uses a methodology of city assessment that goes deep into city services processes, identifying the specific areas that have higher vulnerability to CC hazards. The identification of these areas allows the city managers to implement incisive measures and to estimate costs of those measures improving the city resilience. Three case studies are being carried out in different cities (Barcelona, Lisbon and Bristol). Despite the complexity of the methodology of urban assessment, the RESCCUE RAF app can be accessed using a user-friendly interface that can be accessed from anywhere. The access requires authentication due to sensibility of information processed. After authentication, the user has access to a dedicated area where city information can be filled in, in an intuitive way such as: last review of City Master Plan, history of climate hazards or a detailed way of operation of city services. Then, taking advantage INCD infrastructure, this information is processed on-the-fly and several indicators are calculated. This information can then be explored within the app, at multiple levels, using intuitive and interactive chart and tabular information, from a macro view on overall city resilience to specific items like resilience of a specific process of a city service. These results can support targeted efforts and investments in the services that need to be improved. Given its importance and flexibility, the RESCCUE RAF App can be extended to other cities and take a major role in the urban resilience improvement to cope with climate change effects, contributing in the decision making process to avoid human, material and environmental losses.

Energy efficiency is inextricably linked to the sustainability of urban water services (UWS) since it corresponds to 30-40% of operational costs in drinking water and wastewater services. Energy costs are mainly associated with network pumping and aeration in wastewater treatment. A comprehensive framework for diagnosis of energy consumption and efficiency in water and wastewater systems involving four levels of analysis: overall UWS (level 1), each stage of the UWS (level 2), infrastructure component (level 3) (e.g., network distribution area, wastewater treatment facilities) and processes or equipment in each component (level 4) (e.g., pumping station, air mixing equipment). The assessment system proposed for the levels of analysis 2 and 3 and the approach for diagnosis and prioritization is explored in a water utility in this paper. It was demonstrated the potential of the framework to identify the different sources of inefficiencies and the impact in effectiveness and locate critical infrastructures for a more detailed analysis. This demonstrates the potential for applicability of the approach to other water utilities that participate in the Avaler+ project as well for general applicability.

A avaliação de desempenho é uma importante ferramenta de gestão no setor da água e a sua integração na gestão dos sistemas de águas pluviais (SAP) poderá constituir uma mais-valia para as entidades gestoras. Neste sentido, identificou-se a necessidade de desenvolver uma metodologia de avaliação de desempenho de SAP, que seja abrangente, objetiva, padronizada e flexível na sua aplicação. A metodologia apresentada é composta por objetivos, critérios de avaliação e indicadores de desempenho (ID), que constituem etapas de relevo na avaliação de desempenho. O objetivo do presente trabalho consistiu no desenvolvimento de um sistema de avaliação de desempenho a um caso de estudo, na bacia da Quinta do Borel, no concelho da Amadora. Os ID foram calculados a partir de dados obtidos em campanhas de inspeção e monitorização e de simulações hidráulicas de cenários climáticos e soluções de intervenção. As principais falhas de desempenho identificadas relacionam-se com a ocorrência de inundações, a existência de ligações indevidas de efluente doméstico ao SAP, a falta de capacidade hidráulica dos coletores em parte da rede pluvial e coletores sem capacidade de autolimpeza. Foram feitas recomendações de melhoria de desempenho e de obtenção de informação no caso de ID sem dados disponíveis e avaliou-se o potencial da metodologia proposta.

Urban areas are complex, vulnerable and continuously evolving, with interacting strategic services, assets and stakeholders. Potential effects of climate dynamics on urban areas may include the aggravation of current conditions, with identification of new hazards or risk drivers. These challenges require an integrated and forward-looking approach to sustainable urban development. Several tools and frameworks for assessing resilience have already been developed in different fields of study. However, aiming to focus on climate change, urban services and infrastructure, some specific needs were identified. In this light, a resilience assessment framework was developed to direct and facilitate an objective-driven resilience diagnosis of urban cities and services; to support decision on selection of resilience measures and development of strategies to enhance resilience to climate change; to outline a path to co-build Resilience Action Plans; and to track the progress of resilience in the city or in the service over time. The paper presents an outline of the structure of the framework and details the approach used in its development, including engagement tools and actions undertaken to assure stakeholder involvement in its development, validation and testing.

A resiliência emergiu como uma perspetiva atraente em relação às cidades, teorizadas como sistemas altamente complexos e adaptativos [1]. Um dos objetivos do desenvolvimento sustentável, propostos pela UNHABITAT, estabelece a resiliência nas cidades como uma questão crítica. A resiliência é usualmente entendida como a capacidade do sistema de absorver perturbações e reorganizar-se enquanto sofre mudanças. Este processo, de melhoria continua, visa essencialmente reter a mesma função, estrutura e identidade [2]. As soluções baseadas na natureza (Nature Based Solutions, NBS) surgiram como soluções sustentáveis para contribuir para a resiliência das cidades de forma a enfrentar os desafios das alterações climáticas. Alguns exemplos de NBS para controlo de caudais pluviais são bacias de retenção, coberturas verdes, zonas húmidas contruídas, valas com cobertura vegetal, entre outras. A União Europeia (UE) define NBS como ações que visam ajudar as sociedades face aos desafios ambientais, sociais e económicos de forma sustentável [3]. Esta comunicação visa apresentar a contribuição das NBS para a resiliência urbana, analisando os vários projetos e identificando as lacunas existentes. Também será desenvolvida uma análise dos sistemas de avaliação existentes e apresentada a estrutura preliminar de um sistema de avaliação do contributo das NBS para a resiliência urbana.

Nos serviços urbanos de água, os gastos com energia podem corresponder a 25-40% dos gastos operacionais das entidades gestoras destes sistemas. O projeto Avaler+ pretende avaliar e melhorar o desempenho energético dos sistemas de abastecimento de água (SAA) e dos sistemas de águas residuais e pluviais (SARP). A avaliação da situação de referência do consumo e eficiencia energética é determinante para previsão da sua evolução, estabelecimento de metas e avaliação do impacto das medidas de melhoria. Este artigo apresenta a metodologia e os resultados do consumo e eficiência energética setor urbano em Portugal, entre 2004 e 2017. Os dados analisados demonstram um aumento do consumo anual de energia no setor nos últimos 7 anos. Em 2017, o consumo total apurado foi de 1,1 TWh, 62% dos quais nos SAA e 38% nos SARP. Em SAA, o principal consumo de energia ocorreu no bombeamento para captação, transporte e distribuição de água (89% em média), que nos SARP representou, em média, 21%. O desempenho energético das instalações elevatórias tem sido insatisfatório ou mediano (mediana 0,55 a 0,61 kWh/m3/100m), com piores desempenhos no SARP (mediana 0,64 a 0,88 kWh/m3/100m). Os resultados evidenciam que existe um elevado potencial de melhoria de eficiência energética.

Este artigo aborda o estado atual sobre práticas de modelação da qualidade da águas residuais tratadas em sistemas de distribuição, identifica formulações de modelos de qualidade de água e apresenta a adaptação do modelo de substâncias reativas com cloro para simulação da qualidade das águas residuais tratadas, de sistemas reais, no software EPANET-MSX.

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.

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

This document reports the activity developed in FCT EMPOWER+ project (2021-2024) in which new high-performing granular activated carbons (GACs), powdered activated carbons (PACs) and reusable magnetic PACs (MPACs) prepared by steam and CO2 activation of pine nut shells (PNS/Steam and PNS/CO2 activated carbons) were produced and tested for drinking water treatment towards organic matter, pharmaceutical compounds, microcystin-LR and residual chlorine control.

To build the society

D5.8 Set of Policy Briefs on Regulation and Policy Instruments outlines comprehensive guidelines and strategic recommendations to enhance the governance and regulatory frameworks for watersmart systems across Europe. This deliverable builds on the foundational work completed in Task 5.4, which integrates insights from various stakeholders on regulatory and economic aspects, including financial mechanisms, incentives, and tariffs provided by IWW, as well as legal considerations from KWR. Through an analysis of the socio-economic factors and legal barriers identified in Task 5.2 and leveraging the socio-economic metrics developed in WP6, this document provides a set of at least four policy briefs. These briefs aim to foster a supportive environment for the broad application of water-smart solutions, proposing improved policy frameworks at local, national, and EU levels. The timing and thematic focus of these recommendations are aligned with current EU policy processes related to water and the circular economy, identifying optimal windows for the targeted dissemination of these policy briefs. D5.8 serves as a crucial tool for policy officers, stakeholders, and the public, offering synthetic, accessible 'take away' documents that encapsulate contributions from the involved Work Packages.
