Customers are sensitive to the flavour of water. Customers evaluate drinking water based on their expectations, on experiences with their usual drinking water and on experiences with alternative waters. The Philadelphia Water Department provides one example of success in developing a better understanding of customer perceptions and attitudes about tap water taste and odour. Philadelphia found that customers do communicate in ways that water utilities can understand. Water utilities can enhance that communication and collect useful data. In addition, water utilities can characterise their tap water flavour, track it for changes and correlate changes to customer complaints.

Unlike the private concession model applied in urban zones, rural water sanitation services in Chile are managed by rural drinking water (RDW) committees or cooperatives, under a community governance model. This article seeks to understand the tensions and conflicts faced by RDW community governance in the peri-urban territories of regional capitals, which are at the frontier of the private drinking water management model. Based on a political ecology and hybrid governance approach, this research proposes the hypothesis that, on facing urban expansion and water scarcity, the neoliberal institutional framework tends to favour drinking water market governance in peri-urban territories. With this aim, and through semi-structured interviews and participatory observation, focusing on three RDW cases located in the peri-urban zone of Talca, this study develops a critical discourse analysis of community managers and government regulators, identifying their perceptions and positions on current socio-ecological transformations, and community governance tensions. Consistent with the proposed hypothesis, from discourse analysis, it is possible to infer the potential risks of privatization, derived from the implementation of Law No. 20,998, which regulates rural water sanitation services.

<p class="1Body">While progress has been made for providing drinking water through the completion of the Millennium Development Goals and other international programs, millions of people still do not have access to clean drinking water. This study examines how drinking water coverage is impacted using three regime ownership models. Using the framework of the privately-owned, publicly-owned, and decentralized regime models, the impacts of water production, non-revenue water, and unit operation cost are evaluated for drinking water coverage. A sample of 144 utilities across 33 countries were sampled using data from the International Benchmarking Network for Water and Sanitation Utilities. Using ordinary least squares modeling, results indicate that predicting water coverage from water production, non-revenue water, and unit operational costs provided weak explanations of variation for both publicly-owned and decentralized regimes. None of the three regime models established a significant relationship between water coverage and all three independent variables. For publicly- and privately-owned water regimes, decreasing non-revenue water by plugging leaks and improving infrastructure can translate into higher rates of water coverage. For decentralized water regimes, higher levels of unit operational cost can increase water coverage. The regression analyses also showed that broad claims about regime ownership, efficiency, and improved water coverage should be suspect. None of the three regime models established a significant relationship between water coverage and all three independent variables. This suggests that the competing claims that privatized drinking water utilities as being more efficient or more able to provide water coverage as compared to other types of utilities in the literature is not supported when compared across countries.</p>

La présente thèse porte sur une étude des petits systèmes municipaux du Québec (en l’occurrence, ceux desservant 10 000 personnes ou moins) et comporte trois volets. Le premier volet se focalise sur un portrait historique de la qualité de l’eau distribuée et sur les stratégies de gestion. Parallèlement, il met l'historique de la qualité et les stratégies de gestion en relation avec certains paramètres importants de la qualité de l’eau. Les résultats de ce volet montrent que pour les systèmes s’approvisionnant en eau de surface et pratiquant uniquement une chloration, la différence entre le nombre annuel moyen de rinçages des systèmes ayant connu des problèmes de qualité et ceux n’ayant pas connu de tels problèmes s’est avérée statistiquement significative. En plus, certains indicateurs de la pression agricole sur le territoire des municipalités concernées apparurent significativement corrélés avec les épisodes de coliformes. Le deuxième volet porte sur une étude de la variation spatio-temporelle de la qualité de l’eau dans dix petits systèmes. Ces systèmes furent répartis en deux groupes : quatre systèmes qui n’ont jamais ou ont rarement distribué de l’eau dérogeant aux normes microbiologiques provinciales relatives à l’eau potable et six systèmes qui ont très souvent dérogé auxdites normes. Les résultats montrent que les différences entre les deux groupes de systèmes sont essentiellement imputables aux teneurs en chlore résiduel libre et au nombre de colonies de bactéries hétérotrophes aérobies et anaérobies facultatives (BHAA) dans les réseaux de distribution correspondants et, dans une moindre mesure, aux doses de chlore appliquées. Le troisième volet inclut trois parties : la première est un portait des caractéristiques d’opération, de l’infrastructure et de la maintenance ; la deuxième est consacrée au développement d’indicateurs de performance pour les petits systèmes ; alors que la troisième traite des facteurs humains et organisationnels. Le portrait a révélé des tendances intéressantes qui ont presque toutes été confirmées par les indicateurs de performance des systèmes de distribution. Les facteurs humains et organisationnels dégagèrent des aspects tels que les antécédents scolaires, la formation complémentaire, l’expérience, la bonne conscience des nouveaux défis, le niveau de préparation pour y faire face, et l’appui des autorités locales. Dans son ensemble, cette recherche aura permis de procéder à une étude exhaustive des stratégies de gestion de la qualité de l’eau potable généralement mises de l’avant par les gestionnaires de petits systèmes et de développer des outils explicatifs pouvant guider utilement leur action, de même que celle des gestionnaires relevant des divers paliers gouvernementaux.
This thesis presents a study of small Quebec municipal utilities (i.e., serving 10,000 people or fewer) and includes three chapters. The first chapter focuses on a portrait of historical quality of distributed water and on management strategies. Concurrently, it puts historical quality and management strategies in relation to certain important water quality parameters. Results show that for surface water utilities using chlorination alone, the mean difference of annual system flushings between utilities that have experienced difficulties with historical quality and those not having experienced such difficulties proved statistically significant. In addition, some agricultural land-use indicators within the municipal territory appeared significantly correlated with coliform occurrences. The second chapter studies the spatial and temporal variation of drinking water quality in ten small utilities. These utilities were divided into two groups: four utilities that had never or rarely served water violating the provincial drinking water microbiological standards and six utilities that very often infringed upon said standards. Results show that the differences between the two groups of utilities are associated essentially with maintained chlorine residuals and heterotrophic plate count bacteria populations in corresponding distribution systems and, to a lesser extent, to the applied chlorine doses. The study includes three distinctive parts: the first one is a portrait of studied utilities’ operational, infrastructure, and maintenance characteristics; the second part is devoted to development of indicators of performance for the same utilities, whereas the last part deals with human and organisational factors. The portrait revealed interesting trends, most of which had been confirmed by utility performance indicators. As for human and organizational factors, they allowed highlighting such issues like educational background, supplementary training, experience, awareness of and preparedness to take up new challenges, and support from local authorities. Overall, this research enabled a thorough investigation of management strategies the most popular with small drinking water utilities and the development of explanatory tools that may usefully guide action from local managers and government bodies.

Energy efficiency is currently a hot topic on all regional, national, and global stages. Accurate measurements on how energy is being used over a period of time can improve performance of the drinking water utility substantially and reduce energy consumption. Nevertheless, the drinking water industry does not have a specific benchmarking practice to evaluate its energy performance of the system. Therefore, there are no standards to compare energy use between water utilities that have a variety of system characteristics. The goal of this research is to develop quantitative approach to select energy benchmarking parameters of the water system, so the drinking water utilities can use those parameters to improve their energy efficiency. In addition to a typical benchmarking of drinking water utilities, the energy benchmarking can specifically compare energy efficiency of a utility with other utilities nationwide. The research developed a regression model based on the statistical representation of the energy use and descriptive characteristics of the drinking water utilities data throughout the U.S. Methodologies to eliminate singularity and multicollinearity from collinear survey dataset are discussed. The all possible regressions were chosen as parameters selection methodology to identify a subset of most significant parameters, i.e. system characteristics, that can mathematically correspond to energy use across different utilities. As a result, the energy benchmarking would be able to calculate the predicted total energy use of the system from given system characteristics.

Research Doctorate - Doctor of Philosophy (PhD)
Providing adequate volumes of safe, clean drinking water to the world’s growing population is a continuous and increasing challenge for water utilities. While prime attention is placed on health aspects, consumers generally judge water quality by its aesthetic value. The presence of compounds which impart taste and odour (T&O) in drinking water supplies often leads to the misconception that the water is unsafe for consumption, triggering consumer complaints and high treatment costs for water utilities. Two biologically sourced compounds which respectively cause ‘earthy’ and ‘musty’ T&O in drinking water supplies worldwide are the secondary metabolites geosmin and 2-methylisoborneol (2-MIB). The research presented in this thesis was initiated and supported by Hunter Water Corporation (NSW, Australia) in response to earthy-musty T&O problems periodically experienced in drinking water supplies (Grahamstown and Chichester Reservoirs). A preliminary analysis of historical water quality data in these reservoirs revealed a close association between abundance of the cyanobacterial genus Anabaena and elevated concentrations of geosmin, while 2-MIB could not be reliably linked to any routinely measured parameter. Although T&O events are notoriously ascribed to cyanobacteria, the filamentous bacterial genus Streptomyces, major producers of geosmin and 2-MIB in soil, have long been suspected to also play a potential role in imparting these metabolites into drinking water supplies. There has been a distinct paucity of knowledge regarding their ecology in freshwater environments and consequently, their significance as contributors to T&O events is not well-established. This thesis presents both field- and laboratory-based studies which were conducted in order to examine the potentiality of Streptomyces to contribute to earthy-musty T&O problems in drinking water reservoirs. A temporal and spatial sampling program combined with the application of a molecular technique for Streptomyces quantification (qPCR targeting the 16S rRNA gene) established the widespread distribution and abundance of these bacteria within the water mass, bottom sediments and in marginal substrates of the reservoirs. The detection of significantly greater Streptomyces population densities in the water mass during prolonged wet conditions compared to extended dry conditions provided evidence to support the hypothesis that they are washed from surrounding marginal habitats into the reservoirs, consistent with them being ‘terrestrial’ bacteria. Contradicting widespread opinion in the literature that they are not ‘aquatic’ bacteria and survive only as dormant spores in water, vegetative cells (detected through a differential cell lysis protocol for DNA extraction) were found to comprise a considerable proportion of Streptomyces populations in the water mass. Together with the finding that sterilised reservoir water supported the growth and geosmin and 2-MIB production by Streptomyces spp. in the laboratory indicates the potentiality of these bacteria to be metabolically active in water and contribute to in situ production of T&O metabolites.Substrates at the margins of the reservoirs including soil, sediment and plant debris represented the major habitat of Streptomyces and the hypothesis that exposure of such substrates following water level recession during dry conditions stimulates the growth and activity of these aerobic bacteria, was largely supported by both field data and a laboratory simulation of these conditions. Together these studies indicated the potential significance of marginal substrates as a major source of Streptomyces and their T&O metabolites, which can enter the adjacent water mass following rain events. Confirmation that all Streptomyces reservoir cultivars could produce geosmin and 2-MIB provided additional evidence to support their role as potentially significant contributors to T&O metabolites in drinking water supplies. Multivariate laboratory studies examining the influence of physico-chemical factors on the production of geosmin and 2-MIB by Streptomyces spp. established that the production of these T&O metabolites was highly coordinated with the reproductive (sporulation) stage of the Streptomyces life cycle. Thus physico-chemical factors that trigger Streptomyces to cease vegetative growth and enter the reproductive developmental stage would conceivably allow elucidation of the conditions which also trigger significant production of their T&O metabolites. Such conditions included lowest concentrations of macronutrients (C, N and P) while higher concentrations of NaCl and copper were found to favour vegetative growth and thus inhibit T&O metabolite production. In consideration of these results, the levels of physico-chemical characteristics in the surface waters of Grahamstown and Chichester Reservoirs appear to be suitable for Streptomyces growth, differentiation and production of geosmin and 2-MIB. While the biological function of geosmin and 2-MIB is not currently known, many other secondary metabolites produced by Streptomyces function as antimicrobial compounds, produced during times of adversity to antagonise competing microorganisms and coincide with their initiation of reproductive growth. Having established that geosmin and 2-MIB production was stimulated under conditions which also trigger reproductive growth (e.g. nutrient limitation), it was hypothesised that they too may function as antimicrobial compounds, however subsequent co-culturing and antimicrobial assays led to the rejection of this hypothesis. Based on literature evidence, several alternative propositions are outlined regarding the possible biological function of these compounds related to regulation of the formation, germination and dispersal of Streptomyces spores. The findings of the studies presented in this thesis indicate the potential significance of Streptomyces as major contributors to the occurrence of geosmin and 2-MIB in drinking water supplies. Furthermore, understanding of the influence of environmental factors and Streptomyces life cycle stage on the biosynthesis of these compounds and their possible biological function has been extended.

The purpose of this dissertation was to identify factors that contribute to the sustainability of rural water supply facilities (WSFs). Twenty-four interviews were conducted: 16 from rural communities and 8 from water supply agencies. Key findings are that in order to achieve sustainability of WSFs, there is need to ensure that (1) there is an effective community organisation; (2) communities have the ability to operate and maintain WSFs; (3) communities are able to raise adequate user fees for purchasing spare parts; and (4) that there is a strong backup support at the district level to carry out major repairs. Major threats to the sustainability of WSFs include high poverty levels in communities, weak institutional framework and inability of communities to handle major breakdowns.

AbstractProvision of safe drinking water (DW) is one of the major requisites for human health, related to four Sustainable Development Goals (SDGs) of the United Nation 2030 Agenda: SDGs 3 (Good health), 6 (Clean water and sanitation), 11 (Sustainable cities) and 12 (Responsible production and consumption). However, this is hindered by the presence, especially in highly-anthropized contexts, of contaminants of emerging concern (CECs) in DW, that may pose a risk for human health. The present study aims at developing a holistic framework to support both (i) decision-makers for CECs prioritization in DW regulation and (ii) water utilities for the selection of appropriate monitoring and treatment interventions for the optimization of DW supply system. In detail, a quantitative chemical risk assessment (QCRA), including uncertainties related to both exposure and hazard assessments, was developed. Then, it was combined with testing and modeling of CECs fate in treatment processes and in distribution network, obtaining a robust tool to achieve the above-mentioned SDGs. Graphical Abstract

Abstract The water utilities established by the Tajikistan Water Supply and Sanitation (TajWSS) project, which is funded by Swiss Agency for Development and Cooperation and led by Oxfam in Tajikistan in collaboration with Government of Tajikistan focussed mainly on decentralization of drinking water services and ownership of the water supply assets by local governance bodies. However, owing to the increasing demand for water and pressures on water resources as a result of climatic variability, water utilities in rural areas are facing financial, operational and environmental challenges which prevent them from responding adequately. These challenges require highly resilient considerations in the design, construction and management of water supply and sanitation facilities and access to financial resources to overcome unforeseen risks. Oxfam's experience in Tajikistan shows that a community's socio-economic status and water utilities’ business operations were key factors for building the resilience of water and sanitation (WS) systems in rural areas. In this paper, the approach in building WS systems that are highly resilient to disasters or risks in rural areas is investigated along with how different factors such as demand and supply, institutional capacity, access to finance and community ownership affect the sustainability of WS services.

Utility services represent economic activities of special social importance, as they determine the quality of people's everyday work and life. The local self-governments need to provide utility services of acceptable scope and quality for their citizens. Among them, supplying the population with hygienically correct drinking water is one of the main tasks, but also an indicator of sustainability. The aim of this chapter is to investigate the current state of the public utility systems in the Republic of Serbia and consider their future perspectives. The secondary goal of this work is the analysis of sustainability trends related to SDG 6 in the Republic of Serbia. The main conclusion of the work is that there is certain significant progress in transformation and reorganization in the water sector, as well as positive progress in reaching the SDG 6 target, but further institutional and legislative reform is necessary as well as an increase in the volume of investments.

Cyanobacteria are a group of phytoplankton of marine and freshwaters. The accelerated eutrophication of water sources by agricultural and industrial run-off has increased the occurrence and intensity of cyanobacterial blooms. They are of particular concern because of their production for potent hepato-, neuro-, and dermatoxins, being hazardous to human health. Dissemination of knowledge about cyanobacteria and their cyanotoxins assists water supply authorities in developing monitoring and management plans, and provides the public with appropriate information to avoid exposure to these toxins. This chapter provides a broad overview and up-to-date information on cyanobacteria and their toxins in terms of their occurrence, chemical and toxicological characteristics, fate in the environment, guideline limits, and effective treatment techniques to remove these toxins from drinking water. Future research directions were also suggested to fill knowledge and research gaps, and advance the abilities of utilities and water treatment plant designers to deal with these toxins.

Technology and organizational leadership are a part of most major businesses, and this is no different for businesses in the water sector. Delivery of clean drinking water and the treatment of wastewater are priorities for utilities in the United States as they seek to serve their communities. Existing infrastructure continues to age and faces a challenging future ahead as delivery demands grow. Leaders need tools to adequately prioritize, support, and sustain water assets and services for their communities. Continuous improvement mechanisms that could help achieve desired outcomes point to ubiquitous utility themes, such as best practices, artificial intelligence (AI) applications, and regulatory considerations for pre-COVID-19 and post-COVID-19 periods. This chapter will consider the impact of the pandemic on the already strained water sector to determine what has been working for whom and when; this chapter will discuss interdisciplinary lessons learned and culminate in recommendations for effective utility management and optimization.
