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.

Urban drainage asset management gained momentum and importance in recent years because of economic considerations, low levels of services and evidence of the poor condition of many infrastructure components. Maintenance and rehabilitation activities are capital intensive and resources are limited. Physical urban water infrastructure has life expectancies of up to 100 years, while decisions taken in sewer asset management will have long-lasting impact on the functionality and quality of future services provided. These decisions can be supported by different approaches based on multiple sources of information, from various inspection techniques, deterioration models to assess the probability of failure, or technical service life, to sophisticated decision support systems crossing boundaries to other urban infrastructure. This abstract briefly presents sewer asset management in its manifold facets spanning a wide field of research and highlights existing research gaps while giving an outlook on future developments and research areas.

Floods in urban areas are responsible for severe disruptions to services as well as for consequences in several dimensions, to people, built environment and society functions. These events are largely associated with natural phenomena and climate dynamics. Traditionally, drainage and civil protection services are involved in planning for facing floods but this is insufficient. A broader involvement of communities

As afluências individas a sistemas urbanos de água têm elevados impactos em diferentes dimensões, destacando-se o desempenho hidráulico, estrutural, ambiental, económico-financeiro, na saúde e segurança pública. O LNEC promoveu duas acções do projecto colaborativo iAFLUI - Iniciativa Nacional para o Controlo de Afluências Individas, onde foi desenvolvida, aplicada e consolidada uma metodologia para controlo destas afluências.

Neste artigo apresenta-se o balanço energético específico para a avaliação da eficiência energética dos sistemas de águas residuais.

A Vala da Salgueirinha é uma linha de água efémera que se integra na rede mais vasta de valas de escoamento de águas pluviais e superficiais que atravessa toda a península de Setúbal. Sendo das linhas de água mais importantes do concelho de Palmela, é aquela que, em períodos de pluviosidade intensa, maiores perturbações provoca nos aglomerados urbanos, em vários troços da rede viária e nos campos ribeirinhos, devido a inundações. Presentemente, o Município de Palmela encontra-se a regularizar o troço jusante desta linha de água, numa extensão de 5.500 m. Este município pretende, numa segunda fase, proceder à regularização, para montante, da restante linha de água, numa extensão aproximada de 5.600 m, bem como à construção de uma bacia de retenção. Em alternativa ou complementarmente à bacia de retenção, poderão ser equacionados armazenamentos em outras áreas periurbanas, tirando vantagem das condições orográficas do terreno. Neste artigo apresentam-se os objetivos, a metodologia do trabalho e os resultados preliminares do estudo hidrológico que está a ser desenvolvido na bacia hidrográfica da Vala da Salgueirinha, a montante da localidade de Lagoínha, em Palmela. Prevê-se que com a conclusão do estudo seja possível quantificar a redução dos caudais de ponta recorrendo a armazenamentos relativamente naturais em áreas rurais, aumentando a eficiência da bacia de retenção a construir, ou permitindo reduzir o seu volume, diminuindo os custos de construção, expropriações e impactes gerados no local e contribuindo para uma maior harmonização da linha de água e sua envolvente.

Em resposta aos desafios relacionados com o uso eficiente da água, ao potencial de eficiência hídrica e ao nexus água-energia nos edifícios, e em resultado de um processo participativo envolvendo vários stakeholders, foi desenvolvido pela ADENE

Foi explorada em laboratório a produção de novos carvões ativados em pó (PAC) por ativação com vapor de água e com CO2 de cascas de pinhão (PNS), tendo sido testadas várias condições. Os PAC foram testados em ambiente operacional, com adsorção competitiva de três compostos farmacêuticos (PhC) em efluente secundário de ETAR, tendo o PAC activado com CO2 mostrado melhores remoções dos PhC do que o ativado com vapor de água. Ambos os PNS PAC superaram os melhores PAC comerciais testados.

Com esta comunicação pretende-se partilhar conhecimento sobre algumas técnicas disponíveis para identificação e localização de afluências indevidas potencialmente mais relevantes, com foco nas afluências de origem pluvial, desenvolvidas no âmbito do projecto colaborativo iAFLUI.

In the present work the surface chemistry of a commercial AC (NucharA74) was modified by thermal treatments at 500 ºC (NucharA74/500) and 800 ºC (NucharA74/800) under N2 (see pHPZC values on Table 1). The textural properties of the materials were characterized by N2 adsorption at -196 ºC and FTIR spectra. Materials were tested for the simultaneous removal of three PhCs (100 ?g/L) spiked in mineral aqueous solution. PhCs were selected considering their worldwide occurrence and persistence in wastewater treatment plant (WWTP) effluents (validated in LIFE IMPETUS, www.life-impetus.eu) and adsorption key-properties: carbamazepine (CBZ - neutral, hydrophobic), diclofenac (DCF - anionic, relatively hydrophobic) and sulfamethoxazole (SMX - anionic, hydrophilic). Concerning PhCs, DCF and CBZ were the most adsorbable compounds. The lower adsorbability of SMX may result from its hydrophilic character and higher polar surface area. The adsorptive capacity was generally more efficient for NucharA74/800, followed by NucharA74/500. The good performance of NucharA74/800 was attributed to its pHPZC value, as it has a lower negative net surface charge density than the other ACs. NucharA74/500 material, despite its high acidity and slightly smaller microporous volume than that of NucharA74, showed a higher adsorption capacity for all PhCs. Thus, the changes on the surface chemistry during the thermal treatment of NucharA74/500 may have favoured the adsorbent-adsorbate interactions, compensating the electrostatic repulsions.

O dimensionamento adequado de sistemas de distribuição de água é essencial para assegurar a eficiência e a eficácia do seu funcionamento. Tradicionalmente, o dimensionamento é efetuado atendendo apenas ao objetivo de minimização de custos, não sendo contemplados outros objetivos como o desempenho e a fiabilidade. Uma vez que é pretendido pelas Entidades Gestoras que os seus sistemas sejam capazes de manter o abastecimento perante situações anómalas, é fundamental que a fiabilidade seja tomada em conta no processo de dimensionamento do sistema. Este artigo apresenta os resultados de um trabalho exploratório de objetivos e de índices de fiabilidade. Apresenta uma metodologia para a escolha dos diâmetros das condutas de um sistema de distribuição de água, atendendo à minimização de custos e à maximização da fiabilidade do abastecimento em caso de ocorrência de uma avaria, com a análise de dois indicadores de fiabilidade, o Índice de Resiliência (RI) e o Índice de Resiliência da Rede (NRI). O problema de otimização é resolvido recorrendo a Algoritmos Genéticos, integrando as restrições relativas à pressão mínima e às velocidades máxima e mínima como penalizações na função objetivo. A aplicação da metodologia a um caso de estudo real resulta em três soluções de dimensionamentos distintas com objetivos contraditórios.

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.

Urban water services make use of extensive networked infrastructures

Rainwater harvesting systems (RWHS) can result in important benefits, but there are a number of potential negative risks. The risks associated with RWHS depend on several factors and duly consideration is required to ensure that risks associated with this type of solutions are low. Therefore, a generic and systematic approach to manage risk is required. This chapter introduces a brief overview of concepts and terminology adopted. Subsequently, an overview of common approaches to risk management is presented. The chapter focuses on specific aspects for the application of these approaches to RWHS, with emphasis on risk identification, specific risk treatment action, and monitoring. Different approaches on how to determine risks such as water safety plan (WSP), risk management process (RMP), and hazard analysis and critical control point (HACCP) can be used, but all of them have some common steps.

Conventional treatment processes for the removal of cyanobacteria and cyanotoxins are thoroughly described in this chapter, including chemical treatment (heavy metals, herbicides, and photosensitizers), coagulation/flocculation combined with air flotation, and various adsorption processes.

Water scarcity and asymmetric space-time distribution is driving many countries to seek nonconventional water sources. Treated wastewater is an emerging alternative water source but, depending on its use(s), it may require an increased level of water treatment. At the same time, the list of emerging contaminants (ECs), including pharmaceutical compounds (PhCs), of great relevance to the environment and to public health continues to grow. Further, many of these contaminants are partly or strongly resistant to conventional treatment in water and wastewater treatment plants (WTPs and WWTPs). Therefore, advanced treatment processes are being developed or optimised for improved PhC control. Amongst them, hybrid processes of adsorption

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 evaluated in order to reduce the online monitoring investment costs.

Municipalities and/or sewer operators have to decide investment strategies to rehabilitate and upgradeboth the efficiency and quality of their sewer systems. Frequently, such decisions are based on limitedinformation and do not consider simultaneously the sewer pipes, the wastewater treatment plant andthe receiving environment, especially groundwater. In order to provide some basic working elements tohelp operators in making such decisions, Work Area 4 (WA4) within the APUSS project, described in thepresent chapter included three topics:i) the definition of a set of infiltration/exfiltration specific performance indicators, PIs;ii) the proposition of a generic multi-criteria methodology to compare investment strategieswhich is elaborated separately in Chapter 10 and;iii) the analysis of cost structures of sewer systems and costings for the new tracer methods proposed in the APUSS methodology (as outlined in Chapter 2).

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.
