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.

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.

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.

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.
