Os sedimentos ocorrem em todos os sistemas de distribuição de água. Umavez acumulados, podem ser ressuspensos e chegar à torneira do consumidor,dando lugar ao aparecimento de água com turvação amarelo-acastanhada. Ofenómeno, que pode ser provocado por variações repentinas de velocidade,pode causar alterações de qualidade da água, difíceis de prevenir, ecomprometer a qualidade do serviço prestado e originar reclamações. Paragerir os sedimentos nos sistemas de distribuição é necessário conhecer assuas principais origens e compreender os processos que determinam a suaacumulação e ressuspensão. Neste artigo, resume-se o estado doconhecimento do âmbito desta problemática, nomeadamente no queconcerne às características e comportamento dos sedimentos específicos doaparecimento da água com turvação amarelo-acastanhada, e às condiçõeshidráulicas para a sua acumulação e ressuspensão. Além de metodologiaspara amostragem representativa e estudo dos sedimentos, descrevem-semedidas para a sua monitorização. São relevados e discutidos os aspetospráticos para gestão dos sedimentos, nomeadamente ações possíveis(descargas na rede) para prevenção ou remediação do problema.

Sludge (or biosolids) management is highly complex and has a significant cost associated with the biosolids disposal, as well as with the energy and flocculant consumption in the sludge processing units. The sludge management performance indicators (PIs) and indices (PXs) are thus core measures of the performance assessment system developed for urban wastewater treatment plants (WWTPs). The key PIs proposed cover the sludge unit production and dry solids concentration (DS), disposal/beneficial use, quality compliance for agricultural use and costs, whereas the complementary PIs assess the plant reliability and the chemical reagents' use. A key PI was also developed for assessing the phosphorus reclamation, namely through the beneficial use of the biosolids and the reclaimed water in agriculture. The results of a field study with 17 Portuguese urban WWTPs in a 5-year period were used to derive the PI reference values which are neither inherent to the PI formulation nor literature-based. Clusters by sludge type (primary, activated, trickling filter and mixed sludge) and by digestion and dewatering processes were analysed and the reference values for sludge production and dry solids were proposed for two clusters: activated sludge or biofilter WWTPs with primary sedimentation, sludge anaerobic digestion and centrifuge dewatering; activated sludge WWTPs without primary sedimentation and anaerobic digestion and with centrifuge dewatering. The key PXs are computed for the DS after each processing unit and the complementary PXs for the energy consumption and the operating conditions DS-determining. The PX reference values are treatment specific and literature based. The PI and PX system was applied to a WWTP and the results demonstrate that it diagnosis the situation and indicates opportunities and measures for improving the WWTP performance in sludge management.

Wastewater services are fundamental for the protection of public health and environment, population wellbeing and sustainable development of communities. The value of urban water assets represents a major part of all public infrastructures. These assets must be managed rationally and efficiently, justifying investment priorities in a clear and straightforward way. Effective decision-making requires a comprehensive approach allowing the incorporation of desired performance at acceptable risk levels, considering investment and operational costs. Advanced sewer infrastructure asset management (IAM) is key to achieve and ensure adequate future levels of service, in issues such as flooding of urban areas, pollution prevention, balancing performance, risk and cost. The paper illustrates the integration of different support tools and methods by implementation of the AWARE-P procedure for planning IAM, demonstrated by the experience of fourteen wastewater utilities.

Abstract An overview is presented on the projects that are being carried out by Water Quality and Treatment Laboratory team of LNEC which uses activated carbon based technologies for treating water or wastewater. Emphasis is given to the chemical enhancement of conventional wastewater treatment using

Methods to detect outliers in network flow measurements that may be due to pipe bursts or unusual consumptions are fundamental to improve water distribution system on-line operation and management, and to ensure reliable historical data for sustainable planning and design of these systems. To detect and classify anomalous events in flow data from district metering areas a four-step methodology was adopted, implemented and tested: i) data acquisition, ii) data validation and normalization, iii) anomalous observation detection, iv) anomalous event detection and characterization. This approach is based on the renewed concept of outlier regions and depends on a reduced number of configuration parameters: the number of past observations, the true positive rate and the false positive rate. Results indicate that this approach is flexible and applicable to the detection of different types of events (e.g., pipe burst, unusual consumption) and to different flow time series (e.g., instantaneous, minimum night flow).

Concerns over the efficiency of household water use have been increasing worldwide: water is intensively consumed with high inefficiencies. Detailed methodologies for the assessment of consumers

The energy costs usually represent the second largest part of the running costs of a wastewatertreatment plant (WWTP). It is therefore crucial to increase the energy efficiency of theseinfrastructures and to implement energy management systems, where quantitative performancemetrics, such as performance indicators (PIs), play a key role. This paper presents energy PIs whichcover the unit energy consumption, production, net use from external sources and costs, and theresults used to validate them and derive their reference values. The results of a field study with 17Portuguese WWTPs (5-year period) were consistent with the results obtained through aninternational literature survey on the two key parcels of the energy balance

Water smart metering enables the measurement and reporting of water consumption at sub-daily intervals. However, assuming that increased availability of consumption information will necessarily result in changed behaviour is simplistic. The main scientific challenges for iWIDGET project are the management and extraction of useful information from vast amounts of high-resolution consumption data, the development of customized information to influence awareness and support behavioral change, and the integration of iWIDGET concepts into a set of decision-support tools for water utilities and consumers. In this paper, it is described the evaluation general framework, the iWIDGET system

This paper presents a novel methodology for evaluating the efficiency of indoor domestic water use based on performance assessment functions that convert state variables (e.g. flow rate, volume) into performance indices ranging from 0 (the lowest performance) to 300 (excellent performance). Performance functions have been developed for the most common water use devices in the household. An overall household water use index was obtained from the individual water use device indices by weighting each device in accordance with the consumption structure of the household. The application of this methodology to 43 households allowed the quantification of potential water savings and the identification of device-specific measures to increase the water use efficiency

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.

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

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.
