Preventive Maintenance Policy

Must the water networks be fail-proof or must they remain safe during a failure? What must water system managers try to achieve? The present paper introduces a methodology for the hierarchical analysis (in time and space) of the preventive maintenance policy of water supply networks, using water supply system performance indices. This is being accomplished through a technical–economic analysis that takes into account all kinds of costs referring to the repair or replacement of trouble-causing parts of the water supply network. The optimal preventive maintenance schedule suggested by the methodology is compared with the empirically based maintenance policy applied to the Athens water supply system.

The City

The city of Istanbul has important water system remnants from old civilizations among which water line systems begun with Byzantine period and continued during Ottoman era, including Kırkçeşme water supply system. The original gallery structure within the Kırkçeşme system has been altered with time at some places as a result of necessary planning activities, restoration and repair works. All these activities helped to keep almost the system originality. Since its first opening in 1564, its discharge increased steadily as a result of additional drainage feeding line connections to the main gallery. However, through time only a couple of the 570 additional lines have remained in operation. Although other similar establishments have perished in time without leaving even traces, the Kırkçeşme system is its vivid and harmonious appearance in front of eyes even today. Four dams were constructed at the most convenient locations along the water supply lines from 1620 to 1818. The water from the streams was collected during the rainy season and discharged to the city at times of need with increasing capacity. In general, the Kırkçeşme system has two branches: one extends towards the east, which seemed to have more water, due to its feedback from the Kirazlı, Topuz and Paşa tributaries of the Kağıthane stream; the other branch is westwards which is fed by the Ayvad Deresi, Orta Dere and Bakraç Dere tributaries of the Kağıthane stream. All the water are brought together at Başhavuz (main pool) south of Kemerburgaz, where they collectively enter the main supply line crossing the Alibey Stream over the Mağlova Aqueduct, and then joining a branch from the Cebeciköy Stream and finally flow in towards the south. In a historical document called Tezkiret'ül Bünyan, (The Book of Structures) the author states that Sinan pledged to the Sultan about the existence of some old waterways. However, the Roman waterway still remains in the vicinity of Cebeciköy, which is located at a higher elevation than the Kırkçeşme water supply line but ran parallel to it. The water supply system should have integrated perspective for operation and maintenances. On the other hand, standing structures give to humanity the impression that the stability and design carry not only water, but also valuable cultural heritage. Moreover, they connect many civilizations with each other and also past as well as future.

<p>Water supply system is a critical infrastructure. Main task of urban water system is to provide consumers with drinking water in adequate quantity, at the required quality and pressure corresponding to current standards.</p> <p>For the purposes of this paper, operational reliability of the water supply system is defined as the ability to supply a constant flow of water for various groups of consumers, with a specific quality and specific pressure, according to consumers demands, in specific operational conditions, at any or at a specific time.</p> <div> <p>The main aim of this paper is to present a method for risk analysis using Bayesian process. The proposed method made it possible to estimate risk associated with the possibility of partial or total loss of the ability of water supply system operation. The paper proposes to consider two types of risk: the first type, associated with the possibility of interruptions in water supply and the second type, associated with the possibility of tap water contamination.&nbsp;</p> </div> <p>&nbsp;</p>

Water supply system in the urban type sett lement Volzhsky of Samara Region has typical structures: water intakes from wells, water treatment plants, a pumping station of the second elevation with clean water reservoirs, elevated tanks and water supply network. Water supply system plays a signifi cant role in providing consumers with water. Water supply pipelines in the urban type sett lement Volzhsky have considerable deterioration, some emergency pipelines have been replaced with new ones, but with a smaller diameter. Today, the sett lement water system proves equal to its tasks, but if we take into account the new trends in water consumption and putt ing new facilities in operation it will be clear that this system requires substantial modernization.

The water supply in sufficient quantity and quality is one of the priorities for populations. Due to the shortage of resources and the priority in the costs with the water supply and the expenses with commercial available GIS, the application of open and/or free geo-technologies is relevant. This study aims to combat losses in a water supply system, made a composition in a GIS databank, focusing on the spatial display of repair and maintenance services in the water network. The patterns in the demands of the work that led to the establishment of preventive maintenance routines were identified, resulting in the gradual reduction of losses in the municipality of Coronel Sapucaia / Mato Grosso do Sul State

Supply Systems

Water supply systems are dynamic in nature, owing to the effect of climate change and consumer demand uncertainties. The operation of such a system must be managed effectively to meet up with the uncertainties, thus posing a key challenge. Unfortunately, previous information and communication technology (ICT) solutions could not provide the necessary support for applications to deal with the dynamics of the changing physical environment. Nevertheless, tremendous growth in technology offers better possibilities to enhance water supply systems’ operations. As a result, development in technology in sensing and instrumentation, communication and networking, computing and control is now jointly integrated with water supply system infrastructures to enhance the water system operations. One such technological paradigm shift is the cyber-physical system (CPS). In this paper, we present the concept of the CPS in the water system context and investigate the CPS applications to water supply system monitoring. Also, the various applications of CPSs and the application domain requirements are outlined. More importantly, research studies on its application to water system monitoring are scrutinized. As such, key challenges sounding the applications in WSSs are identified. We then outline the areas of improvement for further studies.

Hot Water Supply System

With energy saving and comfort as top priorities, a hot water supply system is designed with solar energy and gas as compound heat sources. In the design, mathematical models are set up for the solar energy and gas compound hot water system and for its economic evaluation. Taking a three-bedroom flat building in Guangzhou City for example, a whole years energy consumption for domestic hot water is simulated; the gas consumption is calculated; comparisons are made between the new system and the gas hot water supply system in terms of their technique, economy and energy efficiency. Results show that the solar energy and gas compound hot water supply system effectively saves energy and has good economic benefits.

Abstract The most unusual aspect of Byzantine Constantinople's water system was the large number of cisterns throughout the city. This research integrates the two most recent in-depth studies of the cisterns to determine that there have been at least 211 cisterns attributed to the Byzantine city. The distribution of the cisterns indicates that the size and number of cisterns constructed reduced over time, with more and larger cisterns developed prior to the 7th century. Cisterns are concentrated in the older area of the city and sparser on the periphery, but with later ones more common in the peripheral areas, suggesting that water provision was extended over time, and although the majority of cisterns are small, most storage volume is concentrated in the three largest open-air cisterns. The extended, detailed list produced will allow more in-depth investigations to proceed. Analysis of the distribution of cisterns across the city creates a framework for understanding the development and functioning of Byzantine Constantinople's complex water supply system.
