Characterization of water demand can be of large value for the management of water supply systems. Especially when water resources are limited, permanently or seasonally, the identification of the types of consumers and its characteristics are essential to identify opportunities to promote efficiency and demand management options. For each customer category, information to be obtained includes individual uses, typical daily usage patterns (average and dispersion), specific characteristics and magnitude. Knowledge and systematization of water uses also provides data to improve water balance and thus allows reducing uncertainty in losses estimation. In this paper, a study carried out in Algarve, a region where stress on water supply resources has been increasing, is presented aiming at better characterise water consumption in the region to improve response both to normal and in emergency situations.

Developing data-driven models for bursts detection is currently a demanding challenge for efficient and sustainable management of water supply systems. The main limit in the progress of these models lies in the large amount of accurate data required. The aim is to present a methodology for the generation of reliable data, which are fundamental to train anomaly detection models and set alarms. Thus, the results of the proposed methodology is to provide suitable water consumption data. The presented procedure consists of stochastic modelling of water request and hydraulic pipes bursts simulation to yield suitable synthetic time series of flow rates, for instance, inlet flows of district metered areas and small water supply systems. The water request is obtained through the superimposition of different components, such as the daily, the weekly, and the yearly trends jointly with a random normal distributed component based on the consumption mean and variance, and the number of users aggregation. The resulting request is implemented into the hydraulic model of the distribution system, also embedding background leaks and bursts using a pressure-driven approach with both concentrated and distributed demand schemes. This work seeks to close the gap in the field of synthetic generation of drinking water consumption data, by establishing a proper dedicated methodology that aims to support future water smart grids.

The article discusses the elements of an automated system for collecting, storing and transmitting data on water consumption, modern metering devices, data collection and transmission devices. The author analyzes the shortcomings of existing accounting and analysis automation systems at Russian water utilities. A comprehensive approach to automated systems in the field of water consumption accounting is proposed. The article considers the experience of the State unitary enterprise “Vodokanal of Saint Petersburg” in the sphere development and application of a single automated complex for diagnostics, monitoring and management of the water supply network. The goals and main functions of the complex are revealed, the main stages and results of its implementation are presented.

This article discusses the hydraulic and technological features of calculating water consumption when designing water supply systems for high-rise buildings in order to increase the effi ciency of water supply and distribution in a given projected object. The basic criteria for the operation of water supply systems for high-rise buildings in accordance with modern requirements of regulatory documents are given. The technological need is justifi ed and completed operational, technological and feasibility analysis of the applicability of methods determination of water consumption to improve the effi ciency of water supply systems of high-rise buildings. Advantages and disadvantages of methods for determining the cost of internal water supply performed by various research and design institutes are indicated.

On the example of single-industry towns of the Republic of Karelia the article shows the possibility of restoring the activities of enterprises depending on the state of engineering support of water supply systems. There was a decrease in water consumption, high wear of water treatment plants, the lack of reagent treatment of colored water and, as a result, ineffi cient operation of facilities. It is shown that the reconstruction is possible with the application of the investment program. Projects have been developed for the reconstruction of the technological scheme for purifying low-turbid, high-color water and creating a circulating system for cleaning the wash water of contact illuminators.

During more than twenty years, survey of water supply systems in the cities of Donbass was conducted. The aim of the study was to develop a strategy for managing this sector, which allows for precise monitoring of water consumption and reducing water loss. In the course of the research, water consumption metering was carried out using counters, the operation of the devices was assessed taking into account the accuracy class and installation features. It is established that the actual value of water consumption is below the standard. The water consumption decreases with an increase in the percentage of installation of water meters and with an increase in the number of tenants in an apartment. The need to bring the general house and intra-apartment meters to the same accuracy class and regulate the installation position of the water meter was identified. Based on the optimization of conditions, the program management of water supply systems by means of zoning territories and the installation of ’’clever’’ meters was proposed. Approbation of the water supply management strategy allowed within the project to reduce water losses by 20% and use the technological reserve for the modernization of the water supply system.

The increased probability of occurrence of various hazards to water supply systems due to climate change requires the strengthening of their resilience through effective emergency preparedness planning. This paper introduces a method for the assessment of the resilience of water supply systems, including emergency supply measures. With 20 uniquely defined emergency situations, the technical constellations for possible impairments of the water supply are documented. The system analysis developed for each emergency situation is then used to determine and prioritise all suitable supply measures to reduce the supply deficit. Based on the data of a water utility close to Frankfurt, Germany, the developed system dynamics model was used to examine the resource utilisation for the respective emergency situations and to estimate the amount of water provided. The model allows us to scrutinize and compare emergency water supply measures as well as to identify required resources. Furthermore, the method helps us to prioritize measures as well as to make decisions when planning and providing emergency water supply (EWS).

In recent years, in the Russian cities there has been a decrease about 15-30% the total volume of water consumed and the specific indicator of water consumption per resident. However, this phenomenon is not taken into account in the SP 31.13330.2012, therefore the values of specific water consumption do not correspond to the modern level of sanitary equipment of the buildings and water consumption, which can not be the same for all cities and towns in Russia. Using the standard values of the design loads indicated in this code can lead to a significant increase in the cost of the project and operating costs. Their correction is necessary taking into account the assessment and forecast of the actual values of specific water consumption. This requires appropriate research and updating of specific water consumption standards for the design and reconstruction water supply and sewerage systems. The article describes the parameter justification method for the designed water supply systems under uncertainty of the prospective values of specific water consumption. The technique is based on the fuzzy sets theory and decision-making methodology under uncertainty of the initial information. This technique allows you to make decisions based on the minimum values of investment risks.
