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.

The life quality of the world’s population and its development activities mainly depend on the availability, quantity and quality of fresh water. Water scarcity at many regions around the globe present challenges towards improving efficiency and rationalizing its use. The state of Baja California, México, is located at the northwestern corner of Mexico at a large semiarid region where rain incidence is very low (169 mm annually); thus, its water provision is also scarce. Federal and state governments have made efforts to guarantee water accessibility to its municipalities. The Río Colorado-Tijuana Aqueduct (ARCT) is a large water supply system that provides 5.33 m3/s of water to these cities. Its 6 pumping stations elevate the water 1,061 m through 147 km of pipes, canals and tunnels, and its total installed motor capacity is of 106,000 HP. Pumps are high energy consumers and represent a large fraction of operating costs in water supply systems. The volume pumped by the ARCT in 2010 was of 80.7 million of m3, while consuming 322.7 GWh annually at a cost of 23.8 million dollars. Implementing actions for the saving and efficient use of energy in hydraulic facilities is a worldwide priority to achieve rational water management and therefore national and regional sustainable development. Methodologies that improve energy savings while satisfying system performance criteria should be sought for better performance and management of the water supply systems. For building energy scenarios for such systems, it is necessary to integrate and adapt different methodologies for the simulation and assessment of behavior and performance taking in account hydraulic, electric and economic issues. This paper presents different approaches and results when these methodologies are applied for the case of ARCT.

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.

Abstract Water supply systems that operate intermittently rather than continuously are highly complex. This arises from the interaction of large numbers of internal and external factors that produce major consequences for system operation and management. Handling these problems requires understanding, and to some extent eliminating, their causes. In this paper, Lusaka Water and Sewerage Company, Zambia, is used as a case study that shows how poor governance, demographic and economic dynamics, hydrologic regime change, poor system management and operation, unplanned system extensions, limited skilled manpower, poor electricity supply and lack of customer awareness all contribute to sustaining intermittent water supply. Interdisciplinary approaches are recommended to explore interplays between governance, climate change and technical factors when developing solutions to intermittent supplies.
