Abstract:
This study examines the critical issue of water scarcity in the Dharan Sub-metropolitan city, analyzing the various factors that are driving factors driving water demand and proposing strategies and ensuring water security. This study finds that factors replace with the rapid expansion of residential areas, increasing population, steeper slopes, changing lifestyles, natural hazards, technical and management leakage are major contributors to the growing water shortages in the area, leading to a situation of water instability. However, the study also identifies that factor such as precipitation, geology, soil types, potential water sources in the area offer opportunities for stabilizing the water supply in Dharan Sub-metropolitan. This study highlights the combined effect of these various active factors that led to an increase in per capita demand of water from 71 to 100 lpcd. This increasing water demand and shrinking of surface water led to Interrupted Water pumping and overexploitation. Additionally, the study indicates that due to high level of Non-Revenue Water (NRW) up-to 40%, certain parts of the city’s residents are facing major difficulties in accessing clean drinking water. The study also finds that positive changes in precipitation, supportive soil types and geology in the city of Dharan increases the potential for water recharge and harvesting. In order to achieve a sustainable and climate-resilient water supply, the study recommends implementing Water management tools likewise protective measures for critical water zones, stabilizing stream banks and gullies for surface water source improvement, artificial recharge of the city through Climate Adaptive Recharge Pits (CARP) and slope interception methods, as well as community-based water harvesting for groundwater source improvement. Furthermore, the study suggests establishing R&D unit involving national and local level experts and stakeholders for better planning and management.

Abstract:
This article highlights various features of risk and resilience standard developed by the ASME-ITI and American Water Works Association. The American Water Works Association and ASME Innovative Technologies Institute have jointly developed an American National Standard to enhance the security and resilience of drinking water and wastewater systems. The ASME-ITI, under the Department of Homeland Security’s sponsorship, initiated discussions with the water sector to consider the development of sector-level guidance based on RAMCAP Plus. The RAMCAP Plus process is composed of seven interrelated analytic steps, which provides a foundation for data collection and interpretation, analysis, and decision making valuable for understanding and managing risk and resilience. The process is designed to guide the selection of options that reduce risk and increase resilience, including informing funding decisions. The joint standard fulfils the need identified in the water sector-specific plan. It facilitates the reduction of risk and the enhancement of resilience at water and wastewater systems across America.

Abstract:
Water supply system is a complex system. Aimed at the puzzle of being very heavy in energy consumption of system control and being not better in water supply quality resulted from being inappropriate in control strategy, The paper researched on the energy conservation strategy and control mechanism of water supply system. It discussed the cybernetics characteristic of water supply process, proposed the intelligence based fusion control strategy and the energy conservation executing strategy, and analyzed the control model of water supply purifying process and the control algorithm of constant pressure control system. Based on the comparative study of simulation experiment, the display of response curve demonstrated that the intelligence based control strategy would be better than conventional PID control method. The simulation results show that the proposed strategy combined intelligence based fusion control with speed control by frequency variation has better application prospect in water supply system.

Abstract:
With the fast development of economy in China, some questions have come out gradually, and more and more obviously. For instance the energy in short supply, the water resource exhausted. I have made a simple analysis on the issue that some extant energy is wasted and the water resource wasted in the water supply and sewerage engineering in China, and have put forward some corresponding measures, such as full use of available municipal water supply network head, reasonable control of the flow of overpressure and decompression cost saving measures, promotion of the technology of water reuse and rainwater reuse and other measures. These measures can effectively reduce the energy and water waste in the water supply and sewerage engineering.

Abstract:
Before this research study began, relatively little was understood of the water supply in Constantinople, particularly within the walls of the city. Archaeological work had focused on collecting details of 160 cisterns and a small number of channels and pipes were incidental finds in other excavations. Although no-one had considered the water supply in Constantinople as a whole, the evidence seemed to indicate a sophisticated water management system. With the available data fragmented, and the potential for more evidence limited to serendipitous finds associated with construction work, the only way to move the understanding of the water supply forward is to take a radically different perspective: civil engineers are well placed to envisage the water supply as a working system and make use of their modern design skills and tools to fill in the gaps between the fragmented data. This reimagining of the water supply system was driven by a key piece of knowledge: the water supply worked, and worked for many centuries. That fact, combined with the fragments of physical and literary evidence, the largely unchanged landscape and the fundamental physical laws governing gravity-fed water systems, are enough to start filling in the information to create a complete system. The core work in reimagining the water supply system has been developing an understanding of the physical infrastructure of the distribution system. Although the two most recent and comprehensive studies appeared to agree that there were about 159 cisterns in the city, close examination of the available data showed that there were actually 209 with the possibility of more. An evaluation of the aqueduct routes in previous studies highlighted inconsistencies with newly available evidence: alternative routes were designed that tied together the available evidence, providing a consistently downhill route, shorter and more straightforward to construct. Having established the number and spread of cisterns and the locations of the aqueducts, it was possible to create a network delivering water from the aqueduct channels to the cisterns for collection by the public. Consideration has also been given to what occurs at either end of this physical infrastructure. At the upstream end, quantifying and characterising the water source defines the water available to distribute and helps to indicate the purpose of the cisterns. At the downstream end, developing even a basic model of water consumption has enabled the distribution network to move from a static artefact to a system with a quantifiable purpose. The combination of the physical infrastructure, inflow data and demand assumptions in an agent-based model demonstrate that the decisions and assumption made within each element work together and allow a fourth element, management, to be considered. The agent-based model of the water supply enables consideration of a dynamic system and the exploration of a number of 'what if?' scenarios. This exploration concludes that the cistern-based distribution system probably developed because of fluctuations in inflow. It may have been possible for the city to use a merged arrangement on the Aqueduct of Valens inflow, but the burden of pro-active management required to make it successful suggests that a parallel arrangement is more likely. There was likely to be an interconnection between the two main aqueducts, which would have enabled the use of water stored in the largest open-air cisterns.

The United Nation's Millennium Development Goal Target 7.C is to "halve, by 2015, the proportion of the population without sustainable access to safe drinking water". While the UN claimed to have met this goal, studies have shown that the "improved" sources used as a metric to track progress do not always supply safe water. One example of these improved sources is the piped water in Tamale, Ghana, which is an intermittent system. The question raised and goal of this research is to determine whether this water source is indeed safe. The Ghana Water Company Ltd. in Tamale had handwritten notebooks containing almost ten years of water quality sample data. This data was entered into a computer database so it could be analyzed for seasonal and geographic trends as well as to gain an understanding of overall water quality. From this analysis, it was concluded that seasonal trends do impact the pH and turbidity of source water which influences the water provided to consumers. In addition, 42% of samples did not comply with accepted World Health Organization guidelines for residual free chlorine concentrations. Total coliform was present in 2% of samples. Observations of environmental factors made during field work in Tamale found five "no" answers to a sanitary survey indicating at least a medium contamination risk. Overall, these observations indicate that water from the piped network in Tamale is not always safe. Contamination also happens very readily during storage due to high usage of unsafe storage containers in Tamale combined with the low chlorine residuals.

This thesis considers several options for improving the sustainability of Kuwait's water supply system. The country currently relies heavily on desalination and brackish groundwater extraction. The options considered for increasing the flux of potable water into Kuwait include expanding the desalination capacity, importing water from other countries, expanding the uses of reclaimed wastewater, and rainfall harvesting. Options for water storage are also considered, including both aquifer and surface systems. Case studies are presented which demonstrate the potential for indirect potable use of Kuwait's highly purified wastewater, and the importance of a storage reservoir as part of such a system. In order to assess the feasibility of rainfall harvesting, a model was constructed to simulate the runoff processes in the Rawdhatain drainage basin in northern Kuwait. Due to the coarse resolution of the input data, reasonable results could not be obtained using the input parameters gathered from available data.
(cont.) However, through sensitivity analysis, it was discovered that relatively minor variations in soil properties throughout the watershed could produce significant volumes of runoff during extreme rain events. Storage was considered for the small lens of fresh groundwater beneath the Rawdhatain basin or in a surface reservoir constructed in the drainage depression there. All of these options should continue to be considered as Kuwait attempts to expand its water supply in a sustainable manner, though further study will be needed especially in order to understand the hydrologic system at Rawdhatain more thoroughly.

Water distribution systems in cities throughout South Asia (and many other countries) only supply water on an intermittent basis (currently averaging less than 5hrs/day in most Indian cities). Intermittent Water Supply (IWS) creates inequities in water availability and carries public health risks associated with the ingress of contaminants from the surrounding ground through flaws in the aged piping systems. It is a major challenge to upgrade from intermittent to continuous water supply (CWS) as this involves an increase in the operating water pressures which promotes higher rates of leakage. There are currently no reliable computational models for characterizing the transient hydraulic behavior of IWS systems (including pipe filling and draining events) and hence, it is difficult to understand and control IWS systems. In a recent PhD thesis, Lieb (2015) developed an open-source code to solve the dynamics of IWS pipe networks through finite volume solution of the governing 1-D Saint Venant equations using the Preismann slot approximation. The current thesis extends and refines the algorithms proposed by Lieb to enable more robust simulations for pipe networks. Specific modification include algorithms for dry pipes and three-pipe junctions. The thesis proposes a new algorithm for representing the conservation of fluid mass, momentum and energy at a three-pipe junction which is validated by comparing computed loss coefficients with measured data reported in the literature. The research also validates predictions of mixed flow conditions (open-channel and pressured pipe flow conditions) with results from laboratory model tests. The proposed formulation has been applied to simulate a skeletonized pipe network (at a test site in Delhi), where simulations are compared with water pressures during intermittent water supply periods. The proposed analysis represents a first step towards comprehensive modeling of IWS that can be used to improve understanding and control of these systems and to manage the upgrading process for CWS operations.

Abstract:
Includes bibliographical references.
Bulk water supply systems are usually designed according to deterministic design guidelines. In South Africa, design guidelines specify that a bulk storage reservoir should have a storage capacity of 48 hours of annual average daily demand (AADD), and the feeder pipe a capacity of 1.5 times AADD (CSIR, 2000). Nel & Haarhoff (1996) proposed a stochastic analysis method that allowed the reliability of a reservoir to be estimated based on a Monte Carlo analysis of consumer demand, fire water demand and pipe failures. Van Zyl et al. (2008) developed this method further and proposed a design criterion of one failure in ten years under seasonal peak conditions. In this study, a method for the optimal design of bulk water supply systems is proposed with the design variables being the configuration of the feeder pipe system, the feeder pipe diameters (i.e. capacity), and the size of the bulk storage reservoir. The stochastic analysis method is applied to determine a trade-off curve between system cost and reliability, from which the designer can select a suitable solution. Optimisation of the bulk system was performed using the multi-objective genetic algorithm, NSGA-II. As Monte Carlo sampling can be computationally expensive, especially when large numbers of simulations are required in an optimisation exercise, a compression heuristic was implemented and refined to reduce the computational effort required of the stochastic simulation. Use of the compression heuristic instead of full Monte Carlo simulation in the reliability analysis achieved computational time savings of around 75% for the optimisation of a typical system. Application of the optimisation model showed that it was able to successfully produce a set of Pareto-optimal solutions ranging from low reliability, low cost solutions to high reliability, high cost solutions. The proposed method was first applied to a typical system, resulting in an optimal reservoir size of approximately 22 h AADD and feeder pipe capacity of 2 times AADD. This solution achieved 9% savings in total system cost compared to the South African design guidelines. In addition, the optimal solution proved to have better reliability that one designed according to South African guidelines. A sensitivity analysis demonstrated the effects of changing various system and stochastic parameters from typical to low and high values. The sensitivity results revealed that the length of the feeder pipe system has the greatest impact on both the cost and reliability of the bulk system. It was also found that a single feeder pipe is optimal in most cases, and that parallel feeder pipes are only optimal for short feeder pipe lengths. The optimisation model is capable of narrowing down the search region to a handful of possible design solutions, and can thus be used by the engineer as a tool to assist with the design of the final system.

Growing demand for water due to increasing populations, industrialisation and water consuming lifestyles puts stress on existing water supply systems. To cater for the rising demand, water distribution networks are expanded beyond their design capacities and this creates transient “low-pressure-open-channel flow” (LPOCF) conditions. Current water supply models use “demand driven approach” (DDA) methodology which is not able to simulate transient LPOCF conditions, that poses an impediment to management/analysis of pressure-deficient networks. With a case study of the water supply network of Kampala City, LPOCF conditions were studied in this research. A “pressure/head driven approach” (PDA/HDA) was used in order to determine what demand is enabled by particular nodal pressures. Conversion of free surface to pressurised flow was analysed and modelled, with a view to clearly understanding occurrence of this phenomenon. The research demonstrated that if adequate pressures and flows are to be maintained, effectiveness of the water distribution network should be given as much attention as water production capacity. The research also indicated that when network pressures are low, the head-driven approach to water distribution modelling gives more accurate results than the traditional demand-driven methodology. Coexistence of free-surface and pressurised flow in networks prone to LPOCF conditions was confirmed and modelled. Results obtained highlighted the advantages of developing fully dynamic and transient models in the solution of transient LPOCF conditions in water distribution networks. Models developed allow application of PDA/HDA and DDA methodologies in systems that may exhibit LPOCF conditions thus enabling identification, understanding and analysis of the status of all sections of the network. These culminated in the development of a DSS to guide operational decisions that can be made to optimise network performance.

Abstract:
The water hammer induced by abrupt velocity change of fluid flow is inevitable for nuclear power plant systems because of the sudden opening or closing of valves, the sudden startup or shutdown of the pumps and the rupture of pipes. The water hammer pressure wave can damage the pipes and cause the abnormal shutdown of Nuclear Power Plant (NPP). The object of this study is a Parallel Pumps Water Supply system (PPWS) adopted in a NPP. The PPWS is composed of two parallel mixed-flow pumps connected with a check valve separately, a container, a throttle flap and pipe lines. The Method of Characteristic line (MOC) was adopted to evaluate the water hammer behaviors of the PPWS during the alternate startup and shutoff conditions of two parallel pumps. A code was developed using Fortran language to compute the transient behaviors including he peak pressure, the flow velocity and the movement of the valve plate. The results indicate that the water hammer behaviors under low speed startup condition differ from that of high speed startup condition. The maximum pressure vibration amplitude is up to 5.0MPa occurring under high-high speed startup condition. The computation results are instructive for the optimization design of the PPWS so as to minimize the damage potential induced by water hammer.

Abstract:
Civil infrastructure systems—facilities that supply principal services, such as electricity, water, transportation, etc., to a community—are the backbone of modern society. These systems are frequently subject to multi-hazard events, such as earthquakes. The poor resiliency of these infrastructures results in many human casualties and significant economic losses every year. An outline of a holistic view that considers how different civil infrastructure systems operate independently and how they interact and communicate with each other is required to have a resilient infrastructure system. More specifically a systems engineering approach is required to enable infrastructure to remain resilient in the case of extreme events, including natural disasters. To address these challenges, this research builds on the proposal that the infrastructure systems be equipped with state-of-the-art sensor networks that continuously record the condition and performance of the infrastructure. The sensor data from each infrastructure are then transferred to a data analysis system component that employs artificial intelligence techniques to constantly analyze the infrastructure’s resiliency and energy efficiency performance. This research models the resilient infrastructure problem as a System of Systems (SoS) comprised of the abovementioned components. It explores system integration and operability challenges and proposes solutions to meet the requirements of the SoS. An integration ontology, as well as a data-centric architecture, is developed to enable infrastructure resiliency toward multi-hazard events. The Federal Emergency Management Agency (FEMA), and infrastructure managers, such as Departments of Transportation (DOTs) and the Federal Highway Administration (FHWA), can learn from and integrate these solutions to make civil infrastructure systems more resilient for all.

Abstract:
There is much to learn from the recent New Zealand and Japan earthquakes. These earthquakes produced differing levels of liquefaction-induced ground movements that damaged buildings, bridges, and buried utilities. Along with the often spectacular observations of infrastructure damage, there were many cases where well-built facilities located in areas of liquefaction-induced ground failure were not damaged. Researchers are working on characterizing and learning from these observations of both poor and good performance. The “Liquefaction-Induced Ground Movements Effects” workshop provided an opportunity to take advantage of recent research investments following these earthquake events to develop a path forward for an integrated understanding of how infrastructure performs with various levels of liquefaction. Fifty-five researchers in the field, two-thirds from the U.S. and one-third from New Zealand and Japan, convened in Berkeley, California, in November 2016. The objective of the workshop was to identify research thrusts offering the greatest potential for advancing our capabilities for understanding, evaluating, and mitigating the effects of liquefaction-induced ground movements on structures and lifelines. The workshop also advanced the development of younger researchers by identifying promising research opportunities and approaches, and promoting future collaborations among participants. During the workshop, participants identified five cross-cutting research priorities that need to be addressed to advance our scientific understanding of and engineering procedures for soil liquefaction effects during earthquakes. Accordingly, this report was organized to address five research themes: (1) case history data; (2) integrated site characterization; (3) numerical analysis; (4) challenging soils; and (5) effects and mitigation of liquefaction in the built environment and communities. These research themes provide an integrated approach toward transformative advances in addressing liquefaction hazards worldwide. The archival documentation of liquefaction case history datasets in electronic data repositories for use by the broader research community is critical to accelerating advances in liquefaction research. Many of the available liquefaction case history datasets are not fully documented, published, or shared. Developing and sharing well-documented liquefaction datasets reflect significant research efforts. Therefore, datasets should be published with a permanent DOI, with appropriate citation language for proper acknowledgment in publications that use the data. Integrated site characterization procedures that incorporate qualitative geologic information about the soil deposits at a site and the quantitative information from in situ and laboratory engineering tests of these soils are essential for quantifying and minimizing the uncertainties associated site characterization. Such information is vitally important to help identify potential failure modes and guide in situ testing. At the site scale, one potential way to do this is to use proxies for depositional environments. At the fabric and microstructure scale, the use of multiple in situ tests that induce different levels of strain should be used to characterize soil properties. The development of new in situ testing tools and methods that are more sensitive to soil fabric and microstructure should be continued. The development of robust, validated analytical procedures for evaluating the effects of liquefaction on civil infrastructure persists as a critical research topic. Robust validated analytical procedures would translate into more reliable evaluations of critical civil infrastructure iv performance, support the development of mechanics-based, practice-oriented engineering models, help eliminate suspected biases in our current engineering practices, and facilitate greater integration with structural, hydraulic, and wind engineering analysis capabilities for addressing multi-hazard problems. Effective collaboration across countries and disciplines is essential for developing analytical procedures that are robust across the full spectrum of geologic, infrastructure, and natural hazard loading conditions encountered in practice There are soils that are challenging to characterize, to model, and to evaluate, because their responses differ significantly from those of clean sands: they cannot be sampled and tested effectively using existing procedures, their properties cannot be estimated confidently using existing in situ testing methods, or constitutive models to describe their responses have not yet been developed or validated. Challenging soils include but are not limited to: interbedded soil deposits, intermediate (silty) soils, mine tailings, gravelly soils, crushable soils, aged soils, and cemented soils. New field and laboratory test procedures are required to characterize the responses of these materials to earthquake loadings, physical experiments are required to explore mechanisms, and new soil constitutive models tailored to describe the behavior of such soils are required. Well-documented case histories involving challenging soils where both the poor and good performance of engineered systems are documented are also of high priority. Characterizing and mitigating the effects of liquefaction on the built environment requires understanding its components and interactions as a system, including residential housing, commercial and industrial buildings, public buildings and facilities, and spatially distributed infrastructure, such as electric power, gas and liquid fuel, telecommunication, transportation, water supply, wastewater conveyance/treatment, and flood protection systems. Research to improve the characterization and mitigation of liquefaction effects on the built environment is essential for achieving resiliency. For example, the complex mechanisms of ground deformation caused by liquefaction and building response need to be clarified and the potential bias and dispersion in practice-oriented procedures for quantifying building response to liquefaction need to be quantified. Component-focused and system-performance research on lifeline response to liquefaction is required. Research on component behavior can be advanced by numerical simulations in combination with centrifuge and large-scale soil–structure interaction testing. System response requires advanced network analysis that accounts for the propagation of uncertainty in assessing the effects of liquefaction on large, geographically distributed systems. Lastly, research on liquefaction mitigation strategies, including aspects of ground improvement, structural modification, system health monitoring, and rapid recovery planning, is needed to identify the most effective, cost-efficient, and sustainable measures to improve the response and resiliency of the built environment.
