Many municipal governments are currently confronted with the need to restructure water supply systems. This paper examines how municipalities are restructuring water supply utility management in the province of Ontario (Canada), which has recently experienced significant and rapid legislative and regulatory reform in the water sector. The paper analyses restructuring in six different municipalities (Hamilton, Kingston, Peel, Peterborough, Toronto and York). It identifies six distinct business models adopted as an outcome of the restructuring process (delegated management to a private operator, corporatization of services provision, delegated management to a public operator, a municipal commission, a municipal ‘business unit’ and a municipal department) and examines the different approaches to governance adopted during the restructuring process. The case study is conceptualized through a discussion of the governance and restructuring challenges faced by municipalities. As municipalities are often confronted with a bewildering array of business models, governance frameworks and contract types when engaging in a review of restructuring options, the paper situates the analysis of the Ontario case within a general survey of business models for networked water supply. The paper concludes with a discussion of “lessons learnt” relevant to municipalities and higher orders of government when engaging in restructuring of networked water supply provision.

Due to the accelerated industrial and urbanization development, climate change, and increasing populations and life quality expectations, the issue of drinking water shortage has raised much public awareness. The desalination system has been widely applied to accommodate the growing demand for clean water resources despite the continuous concerns about its relatively higher energy consumption and environmental footprints. This research conducted a case study in the Tampa Bay Regional Surface Water Treatment Plant and Tampa Bay Seawater Desalination Plant in Florida, U.S. It analysed the performance and environmental impacts of conventional and desalination water supply systems on three sides: energy consumption, carbon footprint, and solid waste. Potential negative effects of both water supply systems are generally associated with surface water ecology, groundwater aquifers, coastal environment, and marine organisms. Various environmental impact mitigation plans have been proposed to prevent or restore the detriments caused by carbon dioxide emissions, plant construction, and concentrated brine discharge. Due to the deficiency in freshwater resources, desalination technology is more promising through proper regulations and regional sustainable development.

A review of advances in our understanding of the significance of viruses as a cause of waterborne infections is presented. Emphasis is placed on problems associated with failures in water supply systems and the hazards of consuming raw or inadequately cooked molluscan shellfish. Recent developments in laboratory methods for the diagnosis of infections caused by the édiarrhoeal viruses are discussed and many papers cited for further reference.

ABSTRACT Centrifugal pumps are widely used in water supply systems and account for more than 90% of the electricity consumption of water pumping stations. Studies that seek to generalize the characterization of performance curves of centrifugal pumps are extremely useful. A study was carried out on the dimensionless characteristics of the operating conditions of centrifugal pumps for preliminary design estimations of water supply systems aiming at energy efficiency. The research consisted of the analysis of performance curves of centrifugal pumps from which data was collected regarding the point of maximum yield (PMY). The curves and the equations obtained were made dimensionless so that the information could be extrapolated to other situations. A case study was conducted in the Water Supply System of Vale Campus of the Federal University of Rio Grande do Sul (UFRGS) to demonstrate the application of those equations and curves developed. The dimensionless equations were useful to determine which discharge should be adopted so that the system would be more efficient hydro and energetically and, also, to determine how much more energy would be consumed in the case of alteration of the point of operation of the pump by a throttling valve.
