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.

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.

In this paper, the water pumping regime, as well as the water consumption regime with regard to the required quantities and the example of water consumption, with an emphasis on changes in water volume, are examined. This aims to show the functioning of the regime of water consumption, water pumping, as well as finding functional relationships between the mentioned sizes and the volume of the water reservoir. The analysis focuses on questions such as how and in what way, changes in the onset and duration of pumping, as well as different water consumption regimes affect the size of the reservoir volume. The entire analysis in this paper was done to develop a scientifically innovative, but also applicable mathematical model, which is a contribution to the profession and a good basis for further scientific research to improve the operation of the urban water supply system.

There are so many diseases which are caused because of unfiltered water. In the market many products are available for filtration of water, but all that product needs a huge amount of cost for maintenance and installation process. So there is the need for filtration of water at low cost and efficiently. For that there will be an automated system which takes payment in advance and then supplies the water according to the purchased plan ,which is based on the user's needs. Hence the purpose of this project is to develop a system which is based on prepaid payment for water supply and monitoring water supply system for housing society. Water supply is measured by using flow control to control the flow of water according to the usage of the user. By doing this we can decrease the rate of human errors. All payment transactions are recorded in the system for further reference. This System evolves Automatically because it detects the recharge details from the message. After that it will give supply to that user according to their recharge details. This System is fully automated which can overcome the problems of improper bill creation, delay in bill availability and delay in payment process. Also system notify users for upcoming recharge and for water consumption.

Water Network

CWSS in Kotamobagu has various problems such as, pipe water network that has not been operated optimally since its completion in 2012. The number of house connections was merely 424 out of 7,600 targeted until 2016. Other problems in Kotamobagu were related to the supply, backwash, insufficient electrical power supply, no water meter, reservoir leakage, and intake pipes leakage in Poyowa and Bilalang. This research aims to find the root of the problem in terms of Clean Water Supply System (CWSS)'s network system, organization, regulation, and management. The research focused on Poyowa Besar's CWSS and Bilalang-1's CWSS networks in Kotamobagu. The research methods included observation, survey, and policy analysis where respondents were required as sources of information. The respondents were from Sia's and Pontodon's CWSS that represented 162 house connections. Additional respondents representing 30 house connections were selected randomly at Poyowa Besar's and Bilalang-1's CWSS for comparison. The results indicated that the community, CWSS managers, and the Central Government support the existence of Kotamobagu CWSS management. The 30 house connections at Poyowa Besar's and Bilalang-1's CWSS have never been served with water, but the respondents positively hope that the matter will be solved in the near future. They were willing to keep waiting for the water network of Kotamobagu's CWSS. The root of the problem in the Poyowa Besar's and Bilalang-1's implementation was due primarily to a network system that was built by the Ministry of Public Works for the Municipal Government of Kotamobaguwas reportedly not in accordance with procurement regulation. There was disagreement between the Ministry of Public Works and Housing (MPWH) and the CWSS managers related to the items that have to be fulfilled for network infrastructure handover.

Purpose – The chaotic growth of cities results in numerous problems related to public health and urban environment. One of these problems is the crisis in urban water supply systems. The objective of this paper is to develop a mathematical model for the water supply system crisis in urban environment (WSC) able to tackle with the ambiguity of the real available data.Design/methodology/approach – The applied methodology comprises the following steps: (1) identification of the influencing factors in WSC; (2) proposal of a conceptual model for WSC description; (3) gathering and simulation of the necessary and available data; (4) optimization of the conceptual model parameters; and (5) verification of the proposed model performance.Findings – The results indicated that there is a great amount of influencing factors in WSC (showed in the complete text); the conceptual model that was developed is composed by two others partial models ( ). The first partial model explained the water consumption ( ),and the second partial model explained the water availability ( ), in which functions are related to influencing factors in water consumption (i.e. temperature, relative humidity, rainfall, revenues collected, unemployment indicator), and functions are related to the influencing factors in water availability (i.e. total water-loss, intermittence in water supply system). The proposed conceptual model has showed good agreement to the simulated data.Originality/value – The paper is among the first works to describe a WSC model and to analyze the possibility of applying fuzzy logic to deal with the ambiguity of the real data. The water supply crisis in urban environments was adequately modelled.

Daily Water Consumption

Quarterly water consumption data collected in a small water supply system were used for elaboration of a new water consumption modeling approach. In this paper, multi-distribution statistical analysis was performed. As the Anderson-Darling test proved, at least a half out of the ten tested theoretical probability distributions can be used for description of the water consumption. The application of the PWRMSE criterion made it possible to determine, which of the tested theoretical distributions is the best-fitted to the empirical data set. In the case of total daily water consumption for the group of the households, it was Johnson distribution, whereas for the average daily water consumption per capita, it was GEV distribution. Based on the best-fitted probability distribution, a 25-year water consumption simulation with the Monte Carlo method was conducted. Because methodology of this study is based on the probability distributions, even if the type of theoretical distribution of the water consumption will change, it will be still possible to use this simulation method by assuming the other distribution.
