Abstract:

This thesis presents the results of an investigation into the development of quality management in Thailand. The research was conducted in order to draw up an overall picture of quality progress in Thai industry, to provide useful insights for Thai companies and policy-makers, as well as to compare Thailand with other developing countries. This research has adopted an integrated approach to research methodology comprising both survey and case study methods. Four linked empirical research projects were conducted to obtain an insight into quality management, particularly the ISO 9000 series of quality systems standards, Total Quality Management (TQM), and a 'foundation level' quality system, within Thai industry. The in-depth study of ISO 9000 implementation identifies the driving forces encouraging Thai industry to pursue ISO 9000; four types of ISO 9000 implementation process; implementation factors and obstacles; the impact of implementation process and future plans after a company has achieved ISO 9000 registration. The study of TQM implementation in companies located in Thailand reveals that the companies studied have each adopted different, but successful, approaches to TQM implementation. The Thai Foundation Quality System Standard (TFQSS) has been proved to be suitable for Thai SMEs. Findings from the four individual research project together provide some new insights into the development and implementation of quality management in a Thai perspective. As a result of the study, a TQM framework was developed. The framework identifies three broad dimensions of quality management in a Thai organisation, which are: - Three aspects of quality management; Five stages of development; and Four implementation paradigms. An organisation that wishes to embark on a quality journey can examine its status against the framework in order to start, or to improve a particular aspect that is found to be unsatisfactory. After identifying some criteria for the assessment of national quality development, a simple model of quality management in developing countries is proposed to depict comparative characteristics of quality management within these countries. It is concluded that, among developing countries in South and East Asian region, Thailand is in the middle of the spectrum of development.

Abstract:

Knutsford redevelopment is part of the Local Government’s agenda to incorporate sustainable living into the residential sector at affordable prices. This development follows on from the newly established White Gum Valley (WGV) and currently constructing East Village. Both of the sites have newly developed technology to demonstrates sustainable living in a density wise design. East Village is being developed to show similar results with more sustainable and saving initiatives such as the use of solar energy, rainwater harvesting on a lot scale, and a community battery to provide for the residents. Knutsford is stage 4 of the development plan that is occurring in Fremantle. This site will follow along the footsteps of previous establishments with improvements to show better results. In order to achieve this, the site needs to meet specific criteria that allow the usage of the natural resources, and if those are not met, the savings initiatives will need to be reconsidered to the basic options that are used by the homes around Perth. Perth is one of the top cities per capita that has the highest usage and consumption of water in Australia with 123000 L/person (Water Corporation 2019). The Water Corporation is currently working on ways to reduce water usage by 15% before 2030 in order to ensure we have a healthy supply of water for future generations. The Water Balance Model that will be developed for the site at Knutsford needs to show and demonstrate that the reduction in consumption can occur not just in a household scale but a community-wide scale in Perth and that it is readily achievable when specific steps are taken into consideration.

ENGLISH ABSTRACT: The processes of monitoring, modelling and managing the water quality of a catchmerit system including all its unique complexities and interrelationships requires an innovative tool or set of tools to help water managers with their decision making. Numerous methods and tools have been developed to analyse and model the real world. However, many of these tools require a fair degree of technical expertise and training to operate correctly and their output may have to be translated or converted to meaningful information for decision-making using a further set of analytical and graphical display tools. A more appropriate technique for management would be to combine all these functions into a single system. The objective of this research was to develop one such tool, an integrated water quality information system (WQIS). A review of the literature revealed that there has been extensive research and development of tools for the management of individual aspects of water resource distribution, augmentation and quality. However, these tools have rarely been integrated into a comprehensive information system offering decision support to a wide variety of river users and managers. Many of the literature sources also noted that a process of interactive development and integration (i.e. including the intended users in the decision of which components to include, the interface design and the graphical display and output) was vital to ensuring the information system becomes an integral part of the users routine work and decision-making. The WQIS was developed using the recommendations from numerous knowledgeable persons in response to questionnaires, interviews and a prototype demonstration. It includes the results of hydrodynamic river and reservoir simulations and the ability to perform operational river scenario testing. However, the development process is continual and always evolving based on the current or local requirements of water managers. These further developments and research needs are discussed in more detail in the conclusion.
AFRIKAANSE OPSOMMING: Die proses om die waterkwaliteit van 'n opvanggebied, met al die unieke kompleksiteite en onderlinge verhoudings van so 'n stelsel te monitor, modelleer en bestuur, vereis 'n innoverende instrument om waterbestuurders te ondersteun in hul besluitnemings. Talle instrumente en metodes vir die ontleding en modellering van die werklikheid is reeds ontwikkel. Die gebruik van hierdie instrumente vereis gewoonlik 'n redelike mate van tegniese kundigheid en opleiding. Dit mag verder nodig wees om die uitvoer van sulke instrumente te vertaal en/of om te skakel na betekenisvolle inligting vir besluitneming deur die gebruik van bykomende analitiese en grafiese vertoon instrumente. 'n Meer toepaslike bestuurstegniek sou wees om al die funksies in 'n enkele stelsel te kombineer. Die doel van hierdie navorsing was om een so 'n instrument, naamlik 'n geïntegreerde waterkwaliteit inligtingstelsel (WQIS), te ontwikkel. 'n Hersiening van bestaande literatuur het getoon dat daar omvattende navorsing en ontwikkeling van instrumente gedoen is vir die bestuur van individuele aspekte van waterbronverspreiding, waterbronaanvulling en waterkwaliteit. Integrasie van hierdie instrumente, in 'n uitgebreide stelsel wat besluitnemingsondersteuning aan 'n verskeidenheid riviergebruikers en bestuurders bied, kom egter selde voor. Verskeie literatuurbronne het ook aangedui dat 'n proses van interaktiewe ontwikkeling en integrasie (m.a.w. in agname van die voorgenome gebruikers se behoeftes in die kense van komponente, die gebruiker raakvlak ontwerp en grafiese vertoon instrumente en uitvoer) noodsaaklik is om te verseker dat die inigtingstelsel 'n integrale deel word van die gebruiker se daaglikse roetine en besluitnemingsproses. Die WQIS is ontwikkel deur gebruikmaking van die insette en aanbevelings van verskeie kenners in reaksie op vraelyste, onderhoude en 'n demonstrasie van 'n prototype. Dit sluit in die resultate van hidro-dinamiese rivier en dam simulasies en die vermoë om operasionele rivier scenario ontledings uit te voer. Die ontwikkeling is egter 'n deurlopende proses, gebaseer op huidige of plaaslike behoeftes van waterbestuurders. Hierdie verdere ontwikkelings- en navorsingsbehoeftes word meer breedvoerig in die gevolgtrekkings bespreek.

Abstract:

Many organisations invest a considerable amount of capital and resources, implementing new techniques to improve their operating performance. Many approaches and techniques are available. New fashionable methods tend to displace older approaches, which may still have value. An effective strategy for selecting and implementing improvement initiatives is an important issue to ensure stakeholder satisfaction. This research aims to investigate quality management and continuous improvement practices, study and analyse several approaches leading to continuous improvement (CI), then construct a framework to assist senior management teams, by providing a decision aid for selecting improvement initiatives. Six key improvement approaches including Total Quality Management (TQM), Six Sigma, ISO9001, Business Process Reengineer (BPR), Lean production (Lean), Business Excellence framework (BE) were selected as the focus in this study. The research was carried out in three phases. Phase One established a conceptual background for the adoption of CI initiatives based on qualitative and quantitative studies of the literature. It described the two decision criteria of fashion setting and pay-offs. Phase Two provided empirical studies of the Quality Management (QM) approaches adopted in three case companies in Thailand. Different decision criteria for the selection of CI approaches were identified from these case studies, together with suggestions from fourteen quality experts and two additional case companies. In-depth analyses of each case study plus interviews with quality experts provided a context and guidance in development of the decision-aid framework for selecting CI approaches. Then in Phase Three the decision-aid framework was proposed, verified, and refined in testing with a multinational case company of four different plants in the Asia Pacific region and two groups of Small and Medium Size Enterprises (SMEs) using action research and assessment questionnaires. The primary outcome of this research is a decision-aid for selecting CI approaches, which demonstrated high utility in practice. The main contributions of this research are a decision-aid for selecting CI initiatives, which was developed and tested, and a number of advancements to the theory of QM and CI, the theory of management fashion, and the application of operations strategy in the QM context.

Abstract:

Air quality in urban areas of Chiang Mai Province, Thailand has seriously deteriorated as a consequence of population growth and urbanization and due to a lack of effective air quality management (AQM). As a result, respiratory diseases among Chiang Mai residents have increased in these affected areas. The health status and experiences of air pollution of both children and adults in Chiang Mai was assessed and improvements recommended to the developing AQM scheme. Air quality modelling, using ADMS-Urban was used to identify probable air polluted and control sites for further study. The polluted sites were found to be located along major roads in the city. However, ADMS-Urban was unable to predict air pollutant concentrations accurately because it could not cope with the very low wind speeds and complex topography of Chiang Mai. As a result, the utility of other air pollution modelling programmes should be investigated. The results of a questionnaire survey conducted with adults showed that urban respondents had a higher percentage of respiratory diseases than suburban respondents. However, later investigations were unable to establish a statistical linkage between air pollution concentrations and respiratory diseases. An ISAAC study was conducted among children attending schools located in the selected sites to assess the potential impacts of air pollution on health. The results showed that the prevalence of asthma was similar in all of the schools (approximately 5%) but that the prevalence of rhinitis (24.3% vs. 15.7%) and atopic dermatitis (12.5% vs. 7.2%) was higher in the urban schools which were considered to be more polluted. Logistic regression analysis identified other factors which may be involved in addition to pollution, including some components of the diet and contact with animals. In order to investigate the adequacy of the AQM system in Thailand, a comparative study was conducted between Hong Kong and Thailand. Both countries were investigated with respect to conformance to Good Urban Governance. The comparison showed that there are significant differences between the two countries and the AQM system in Hong Kong was more highly developed. For example, in contrast to the system in Hong Kong, it was found that there was insufficient involvement of the population in the development and implementation of AQM systems in Thailand. In order to better understand the reasons why the AQM system in Thailand is poor at both the provincial and local levels in Chiang Mai, prioritisation of AQM was assessed for major national environmental policies and plans; at the provincial level, fund allocations to development projects were reviewed; and at the sub-district level; a questionnaire survey was conducted among local government officials. It was concluded that AQM was not given sufficiently high priority in national plans and was generally ineffective and that, due to the non-specific nature of guidelines and frameworks in these plans, it was difficult for government organizations at the lower levels to establish AQM action plans for effective implementation. A range of appropriate measures to improve air quality in Chiang Mai were recommended. These included a more effective management of air pollution, an identified need for training and major changes in the transport system in the city.

Abstract:

Water is most essential but scarce resource in developing countries. Presently the quality & the availability of the fresh water resources is the most pressing of the many environmental challenges on the national horizon. The stress on water resources is from multiple sources and the impacts can take diverse forms. Geometric increase in population coupled with rapid urbanization, industrialization and agricultural development has resulted in high impact on quality and quantity of water in developing countries. The situation warrants immediate redressal through radically improved water resource and water quality management strategies.

Abstract:

Hawaii’s pristine ocean and tropical environment is a keystone of Hawaii tourism and the state economy. Water pollution from stormwater and development threatens the beach quality to both residents and tourists. In order to understand the lost nonmarket value, we assess changes in quality of beach characteristics including water and sand quality, swimming safety conditions, and congestion using a Discrete Choice Experiment of recreational beach users. Further, we study willingness to pay (WTP) for water management strategies in Hawaii using another discrete choice experiment, including structural and nonstructural Best Management Practices, testing, monitoring, and educational efforts. Using a mixed logit model, beach quality results suggest similar preferences among resident and tourists. Both groups consistently have higher WTP to avoid poor quality levels versus obtaining excellent levels. Additionally, water quality is the single most important attribute. For the policy discrete choice experiment, both parties exhibit similar ranking of WTP to initiate water quality management strategies, with improved testing methods followed by education having the highest WTP. Lastly, we use Benefit-Cost analysis to find that all significant management strategies may be viable, since WTP is greater than the predicted cost of implementation based on expert opinion of Hawaiian policy leaders.

Abstract:

Agricultural nonpoint source pollution is recognised as a major cause of water pollution. The characteristics of nonpoint source pollution suggest that an efficient approach should focus on a source control and hence land-use management. Recently, the concept of Payments for Ecosystem Services (PES) has been advanced as an efficient market-based approach to protect in-stream water quality, while simultaneously supporting agriculture. Farmers can be rewarded for the adoption of certain ‘Best Management Practices’ (BMPs) in farming systems. But little is known about the adoption of BMPs in the context of Thai agriculture. This thesis examines the adoption of twelve BMPs on citrus farms in the Ping river basin in northern Thailand. In the context of potential PES development, three studies were undertaken using frameworks from economics and psychology. The first study used a bottom-up engineering approach to estimate economic costs of twelve BMPs at the farm-scale. The total annualised costs, including installation, maintenance, and land opportunity costs of each BMP were compared. The results indicated that land opportunity cost was the largest proportion of total costs. These estimates provided a basis for discussion on how the farmers’ perception of cost may influence their stated adoption intention. The second study used the Theory of Planned Behaviour (TPB), to investigate farmers’ intentions on adoption of twelve BMPs. A survey of 218 citrus farmers was undertaken in the application. Descriptive statistics and frequency of BMP selection were presented. The results showed that soil analysis was the most preferred BMP. A graphical analysis of other preferred measures suggested that these were not always consistent with the known cost information derived (above) and thus farmers’ perceived costs might not be the most important factor influencing adoption decisions. Further analysis based on TPB investigated other factors thought to be significant in farmers’ decision-making. Other potential external and psychological factors influencing adoption were investigated using a multinomial logistic model. The results indicated that the probability of adopting BMPs was associated with other psychological factors and external factors, rather than perceived costs. The significant psychological factors were farmers’ attitudes towards consumers and perception about farm returns, while the significant external factors were, for example, access to information and contribution of family labour to farm workload. The third study was based on the application of Q-Methodology, and aimed to obtain a deeper understanding of farmers’ perception towards BMPs. Seventy two participants were purposively selected from the 218 TPB observations. The results revealed four distinctive farmer groups holding different perceptions towards BMPs. The four groups were conservationist, traditionalist, disinterested, and risk-averse. These provided a specific segmentation to guide policy towards influencing attitudes and behaviours. The results suggested that farmers were not motivated solely by a profit maximisation goal. Overall, key findings from these three studies revealed some fundamental requirements for developing a water-related PES programme. These were: i) factors affecting eligibility to participate; ii) factors affecting desire to participate; and iii) factors affecting ability to participate. This information provided the basis for a set of recommendations addressing the development of the water-related PES programme in the Ping river basin.

Abstract:

Two of the most important environmental challenges in the 21st century are to protect the quality of fresh water resources and to utilize renewable energy sources to lower greenhouse gas emissions. This study contributes to the solution of the first challenge by providing methodologies for optimal design of real-time water quality monitoring systems and interpretation of data supplied by the monitoring system to identify potential pollution sources in river networks. In this study, the optimal river water quality monitoring network design aspect of the overall monitoring program is addressed by a novel methodology for the analysis of this problem. In this analysis, the locations of sampling sites are determined such that the contaminant detection time is minimized for the river network while achieving maximum reliability for the monitoring system performance. The data collected from these monitoring stations can be used to identify contamination source locations. This study suggests a methodology that utilizes a classification routine which associates the observations on a contaminant spill with one or more of the candidate spill locations in the river network. This approach consists of a training step followed by a sequential elimination of the candidate spill locations which lead to the identification of potential spill locations. In order to contribute the solution of the second environmental challenge, this study suggests utilizing available excess energy in water distribution systems by providing a methodology for optimal design of energy recovery systems. The energy recovery in water distribution systems is possible by using micro hydroelectric turbines to harvest available excess energy inevitably produced to satisfy consumer demands and to maintain adequate pressures. In this study, an optimization approach for the design of energy recovery systems in water distribution networks is proposed. This methodology is based on finding the best locations for micro hydroelectric plants in the network to recover the excess energy. Due to the unsteady nature of flow in water distribution networks, the proposed methodology also determines optimum operation schedules for the micro turbines.

Full text

Abstract:

This thesis focuses on local water institutions and practical management arrangements in North West Thailand through the lens of governance in order to begin to establish how the transition to more sustainable water management might be undertaken. Adaptive governance is advanced as a potent means of delivering more sustainable management by providing the flexibility and adaptability to respond to abrupt environmental change, while enhancing participatory and learning opportunities for stakeholders. Insights from the literature on socio-spatial relations are employed to compliment the use of governance concepts by providing insight into the territorial organization of water supply and delivery within the study area, specifically the all-important role of space and socio-spatial relations on day-to-day water management. Data collection methods comprised: (i) 192 face-to-face in-depth semi-structured interviews with key actors; (ii) 20 questionnaires distributed to actors from Joint Management Committee for Irrigation (JMC); (iii) four group discussions with actors from a state-led irrigation project; and (iv) 20 remote interviews with four administrator groups. The analysis identifies the importance of ‘middle ground’ organization as a strategic policy goal to encourage more sustainable water management, set against the pragmatic reality of escalating future demand for water from multiple users at different levels and scales.

Abstract:

The Quinnipiac River Basin, located in South-Central Connecticut, flows 38 miles from its headwaters in New Britain and Plainville, Connecticut to its mouth in New Haven Harbor. The basin is heavily developed, with the majority of the land in the basin classified as residential and urban. The five municipal water pollution control facilities and one large privately-owned water pollution control facility operating in the Quinnipiac Basin are responsible for maintaining acceptable levels of water quality in the Quinnipiac River. While the current water quality management practices within the Quinnipiac River basin are capable of meeting the various water quality standards, changes in the water quality management system may require an adjustment or alteration of the current management practices. The focus of this study is the identification of possible improvements to the current water resources management practices in the Quinnipiac Basin and a discussion of the feasibility of the proposed improvements.

Abstract:

Crop production, soil system, water quality, and economic impacts of four corn silage production systems were compared through a field study including 16 plots (4 replications of each treatment). Systems included a rye cover crop and application of liquid dairy manure in the spring and fall. The four management systems were: 1) traditional, 2) double-crop, 3) roll-down, and 4) undercut. In the fourth system, manure was applied below the soil surface during the undercutting process. In all other systems, manure was surface-applied. In the third system, the rye crop was flattened with a heavy roller after manure application. Simulated rainfall was applied within 48 h of manure application. Measured constituent concentrations in runoff were compared with water quality criteria. Costs and returns of all systems were compared. The undercut system reduced loadings of all nutrients, but increased total suspended solids (TSS) concentration as compared with all other systems. The mean volume of runoff from the undercut system was less than half that from any other system, which influenced all constituent loadings. Mean TSS concentration in runoff from the undercut system was over three times the mean of any other system. The roll-down system had no significant effect on water quality as compared to the traditional system. The undercut system was reasonably effective in keeping phosphate phosphorus levels below the criterion set for bathing water. None of the systems generally exceeded nitrate nitrogen concentration criteria. However, total phosphorus, orthophosphate, fecal coliform and e. coli criteria for drinking, bathing, shellfish harvest, and aesthetics were regularly exceeded by all of the systems. There were no differences among the treatments in effects on bacterial concentrations. The double-crop system produced significantly higher net returns than all other systems only if the value of the rye crop was $92.31/Mg or more. There were no significant differences in net returns of the traditional, roll-down, or undercut systems.

Abstract:

The Maketu Estuary is a shallow intertidal estuary (2.3 km2) located in the Bay of Plenty, North Island, New Zealand. The Kaituna River contributes the largest freshwater flow into the estuary through control gates. Lake Rotoiti and indirectly Lake Rotorua supply the base flow to the Kaituna River, with tributaries along the 50 km reach also significantly contributing to the flow. Water quality within the river is affected by elevated nutrients, faecal coliforms, high oxygen demand and algae concentrations derived from the lakes as well as contributions from tributaries and industrial and urban discharge. Through the use of a coupled hydrodynamic-biogeochemical numerical model ELCOM-CAEDYM, this study aims to examine the nutrient, phytoplankton and hydrodynamics of the Maketu Estuary and lower Kaituna River. Water quality and hydrodynamic measurements were sourced from Environment Bay of Plenty's data archives as well as a number of instrument deployments to collect water velocity, tidal elevation and salinity and temperature measurements during the course of this study. Included in the field work was a survey of the lower river and estuary bathymetry. Model simulations predicted that the maximum residence time in the Maketu Estuary is 1.5 days, occurring in the inner western region. Residence time in the lower river (mouth to 8.5 km upstream) is in the order of hours although some variations were predicted near the river mouth. Growth rates of four phytoplankton groups where assessed over a 15 day period in January 2004. In the Kaituna River ELCOM-CAEDYM predicted that the community growth rates were small with the exception of a slight increase in biomass of the two freshwater groups in a semi-detached river bend. The increase in the loop was correlated with an increase of residence time. In the estuary, marine diatoms showed the highest growth rates in the western region which is expected to relate to retention time and available nutrients. Dinoflagellates showed the smallest variation in predicted growth rates, most likely due to their broad salinity tolerance. The two freshwater species showed a reduction in abundance when mixed with marine water. A principle limiting factor to phytoplankton growth in both the river and estuary is the low residence time. A number of scenarios were simulated in the river and estuary by altering the forcing conditions in the model. A simulation of the increased nutrient load associated with the Rotoiti diversion wall revealed that phytoplankton growth in the river and estuary will not be significantly affected. Because of the close proximity of the control gates to the river mouth, a proportion of water drawn through the structure can be marine. By opening the old river channel, model simulations predicted that a reduction in salinity would be possible, however the outcome of complete freshwater is probably not achievable. Increasing the discharge volume from the river into the estuary was also simulated. The results indicated that increasing the freshwater inflow at Fords Cut would reduce the salinity in the estuary while increasing the net (residual) flow towards the estuary mouth. Increasing the flow would also result in a greater range of salinity in regions of the estuary. Changing the inflow location to the historic Papahikahawai Channel also affected the salinity in the estuary. The most significant effect of an inflow at this location was a reduction of the residual currents in the western region of the estuary.

Abstract:

Lake restoration and management strategies focus on reducing the negative impacts of enriched or polluted inflows. These strategies become of paramount importance when lakes are used for recreational and/or drinking water purposes. Long term control of eutrophication and turbidity problems associated with large inflow loads is usually oriented to catchment management. Although it has been suggested that this is the correct long term approach, public concerns usually require a short term solution. In addition, due to political and economic costs related to changes in catchment management, in-lake restoration technologies have been emerging as a viable pretreatment option, complementary to water treatment plants, both reducing the operational costs of the water treatment plant and ameliorating the water residing in the lakes. This research investigates the effects of two in-lake technologies on the dynamics of inflowing rivers, where basin shape plays a significant role. The three lakes in this study suffer from eutrophication combined with a distinctive water quality problem: from turbidity in Silvan Reservoir (Australia), to heavy metal loads in Coeur d'Alene Lake (USA) and industrial wastes in Lake Como (Italy). Firstly, the influence of basin morphology, wind speed, and wind direction on the fate and transport of two rivers flowing into the L-shaped Coeur d'Alene Lake was examined, and it was shown that transport and mixing patterns in a lake can be greatly influenced by the shape of the lake, leading to important consequences for the plankton ecology in the lake. Secondly, in Silvan Reservoir we investigated the potential to modify the basin shape using vertical barriers, increasing the retention time and hence the barrier capacity to microbial pollution. A final in-lake technology was tested for Lake Como, using a downward pointing impeller to remove polluted water from the coastal margin. Lessons from these three examples indicate that there is significant potential for in-lake remediation at relatively low cost, over relatively short timescales.

Abstract:

A two-year field study was carried out in eastern Ontario to investigate the effects of water table management (WTM) on water quality and crop yields. Corn (Zea mays L.) and soybean (Glycine max Merr.) were planted in alternate strips across the three treatments of 50 cm controlled water table (CWT), 75 cm CWT and free drainage (FD). Drainflow volume and nitrate-N concentration of the drainage water were measured. Soil samples were collected and analysed for total N, P, K, available N, soil moisture and organic matter levels. Chlorophyll-meter readings and plant harvest parameters were also measured. Rainfall, soil and air temperatures were recorded throughout the growing seasons.
The obtained data show that in 1995, the CWT plots significantly increased total drainflow, as compared to FD. In 1996, overall drainflow and nitrate concentrations were significantly reduced. Both the corn and soybean yields were higher with WTM than with FD for both years. (Abstract shortened by UMI.)

Abstract:

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.
