Skyscrapers are common nowadays around the world, especially in cities with limited development area. In order to pump water up to the higher level of a skyscraper, a cascade water supply system has to be installed. Currently, cascade water supply systems are mainly designed based on practical experiences or requirements of existing standards/guidelines that, in fact, are not specifically for skyscrapers. However, thorough studies on cascade water supply system designs are still limited in the literature. This study proposes mathematical models and uses Monte Carlo simulations to evaluate the design flow rate of a typical cascade water supply system that feeds various appliances in a residential skyscraper in Hong Kong. Graphs that showed the correlations between the inflow rate in the supply pipe and water volume in the tank are obtained. While tank storage volume is confirmed, the design flow rate of the cascade water supply system can be determined from these graphs. The proposed mathematical models can also be applied to evaluate the design flow rate of cascade water supply systems in other types of skyscrapers (e.g., office, commercial building) as well as with the changes in water demand patterns in the models.

ABSTRACTThe development of modern water supply systems has varied widely in terms of speed, paths and results, and each supply system has been strongly conditioned by its spatial, socio-economic and cultural context. Barcelona provides a useful illustration of how such a modern system came into being in a particularly dynamic southern European setting. Despite being Spain's leading industrial centre, the driving force behind the introduction of its new water supply system did not come from an industrial imperative but rather from the city's expansion plan, approved in 1859, which gave rise to a proliferation of private initiatives. Later, decisive changes around the turn of the twentieth century led to a concentration of water companies, sewer renewal projects and the entry of water into the domestic sphere, and the extension of the water supply to people's homes. The development of a modern water supply system in Barcelona, however, required a period of a hundred years – from 1867, when the first steam-powered pumping station was built, to 1967, when the water from the Ter River transfer reached the city, allowing new consumption patterns to spread rapidly.

High-rise housing, a trend in densely populated cities around the world, increases energy use for water supply and corresponding greenhouse gas emissions. With emphasis on improving the energy efficiency in the water supply systems, this paper proposes an energy efficiency evaluation measure for the water supply system designs and demonstrates its potential applications in a typical high-rise water supply system. In the proposed measure, the energy efficiency in a water supply system is defined as the potential energy required at the demand locations divided by the pumping energy of the supply system. The outcome of this paper provides useful benchmark references not only for the water supply system designs but also for the water demand management programmes in buildings. Practical application: An energy efficiency evaluation measure for the water supply system designs is used to establish benchmark references for not only the water supply system designs but also for the water demand management programmes in buildings.

Abstract PurposeThe article seeks to examine the understanding of regulation of Non-Utility Water Supply Systems (NUWSS) from perspective of water users in households, the behavioural dimensions of regulation and aspects of the non-utility water supply system that can be regulated.Research Method/DesignThe theory of planned behaviour was used to identify determinants to regulatory compliance across the groups of indicators identified for the regulation of water supply systems. To understand household perception of regulation, interviews were conducted, with questions put to water users in households. A qualitative research approach was adopted, using interviews, and focus group discussion with water users in households.FindingsThe findings indicate that households hold varied perceptions on regulation across the components of the water supply system. Specifically, regulatory compliance by households was influenced by crucial elements such as preferential compliance to regulation within specific aspects of the water supply system. Limitations and implicationsThe inference from this research is based on households from one state in Nigeria. Further exploration of this research in multiple cities and states would widen the applicability of the findings in different contexts.Originality/valueThe study examines regulation and regulatory compliance from the perspective of households who predominantly use Non-Utility Water Supply System (NUWSS) in sub-Saharan Africa.

Supply Systems

A drinking water supply system is an extraordinarily complex system—consisting of kilometers of pipes and various tanks, valves, pumps, and other equipment. This complexity makes it extremely vulnerable to physical, chemical, and/or biological hazards. Therefore, the vulnerability assessment of a drinking water supply system to identify the critical control points is absolutely necessary. This paper assesses the vulnerability of the drinking water supply systems. The assessment is elaborated in systems using water from surface water bodies and groundwater bodies. The critical control points are identified using a risk assessment methodology (identifying the probability of the hazard occurrence and its effect or severity) where the monitoring parameters, and the corrective actions are determined.

Water supply has become a priority for developed and developing nations of the world. Conventional water resources alone cannot meet the growing demand for water in urban cities. Management of the problem is amplified by uncertainty associated with different development strategies. Singapore has limited conventional water resources and progressively architects its water supply system through acquiring and sustaining multiple (alternative) water resources through innovative technologies. The full rationale and merits of such a policy cannot be properly understood based on traditional project valuation methods alone. This paper provides decision support using a real options approach by evaluating innovative water technologies from multiple perspectives under uncertainty. This paper demonstrates that incorporating innovative water technologies into water supply systems can concurrently improve water supply from the financial, political and socioeconomic perspectives. The development of innovative water technologies provides flexibility to the water supply system, and is a fundamental and effective means of risk management. The evaluation of innovative water technologies is based on an integrated real options approach, which provides decision support for architecting water supply systems under uncertainty. The approach gives specific tangible values for the water technologies and complements the general prescriptive Integrated Water Resources Management (IWRM) framework.

The Ancient Roman water supply systems still leave us astonished when admiring the solidity of the ruins of aqueducts surviving around Europe. Some parts of these systems are still in use at present and prove the practical efficiency of Roman hydraulics in the principles acquired from the populations living in the different regions of the Empire. In Pompeii the urban water supply system stands as a clear example of the Roman planning of urban complex networks by using small water towers to serve a limited numbers of users. This allowed to control the derivations and their maintenance and operated a disconnection from the high pressure mains and the low pressure pipes, maintaining a fixed maximum height of water over the final points of discharge. Considering the techniques for pressure reduction as a method to control leakages, this paper examines the ancient Roman water supply system to deduce some applications to modern urban networks built in new housing establishments.

Under the rapid growth of world’s economy and population, the demand for water and energy has been increasing accordingly. Moreover, water and energy are interrelated and form a reinforcing feedback loop. Energy is used not only onsite of water supply systems, but also indirectly for producing materials used in the water systems. As a result, it is important to understand and evaluate the energy embodiment of water supply for sustainable water and energy management. This study uses the Economic Input-Output Life Cycle Assessment software to estimate and compare the embodied energy of one China water supply system (System A) and one US water supply system (System B). It has been found that System B in the US has comparable direct operational energy consumption with System A in China; however, System B consumes much more indirect energy and constructional energy than System A. Possible reasons for the higher indirect energy use in System B might be more administrative and engineering (maintenance and repairing) services involved, lower transportation efficiency, more self water usage within the system and higher labor rates. To satisfy the water demand for the large population, China’s water supply systems have to reduce direct energy consumption during the operation phase by conducting energy budget and adopting energy efficient technologies.
