“…According to the previous requirements, the authors have designed a strategy to develop and maintain a Digital Twin of the water distribution network, integrating the hydraulic model with all the information sources (Bartolín et al 2006) (Figure 2). The application GO2HydNet has been developed to obtain from the different information sources an Epanet-based detailed model for a selected area and a certain time period, which can include all the pipes, operating elements and auxiliary elements that affect the water flows, such as tanks, pumps, air valves, drains, hydrants and house connections.…”

Building and Exploiting a Digital Twin for the Management of Drinking Water Distribution NetworksDigital Twins (DTs) are starting to be exploited in water distribution systems as a tool to improve their management and, in the future, they will be crucial for decision making. In this paper, the authors propose several requirements that a DT of a water distribution system should accomplish. However, the development of a DT is a challenge, and a continuous process of adjustments and learning is required. Due to the advantages of having a DT of the water distribution system, during the last years a strategy to build and maintain a DT of the water distribution network of Valencia (Spain) and its Metropolitan Area (1.6 million inhabitants) was developed. This is one of the first DTs of a water utility.The great benefits of their use in the daily operation of the system ensure that they will begin to be habitual in the most advanced smart cities.

“…Certain advanced information technology methods have been adopted for WDSs. For example, in [30], the authors suggested that GIS is a powerful tool for managing WDSs. GIS can be used to perform certain tasks such as layout and map plotting, demand forecasting, counter-meter installation, pipe connection, leakage and breakdown controls, planning maintenance operations, and asset assessment.…”

An important function of a water distribution system (WDS) is to supply drinking water to each demand point using a pipe network that has minimal impact on the surroundings. To produce a reliable WDS, planning usually requires a significant amount of geo-spatial information. Current planning practices for pipeline systems, which gather geographic information based on maps, are time-consuming and cumbersome. With the rapid developments in computer and information technology, it is necessary to propose a new WDS planning method that enhances the current planning practices and facilitates the decision-making process. The proposed method allows project information in building information modeling (BIM) to be incorporated into a geographic information system (GIS) model, using semantic mapping to incorporate WDS project data and geo-spatial information to facilitate the WDS planning process. Moreover, a 3D visualization model of the proposed WDS project and its surroundings is provided. In addition, topological rules are set to identify any conflicts between the WDS project and its surroundings. A real WDS project was used to validate the method. The proposed method can help project participants better understand the WDS project and its surroundings and identify any errors in the planning process, thus improving sustainable development.

“…This is particularly important today when it is possible to develop very detailed models that include all elements so that pipes are divided into several segments to take into consideration the house connections, manual valves, etc. Nowadays, the tools available for the development of models and the information contained in Geographic Information Systems (GIS) make it possible to build very accurate, detailed models in which all network elements are reflected [29,30]. This is essential, as the hydraulic behaviour of each component directly affects the mixing and transport processes, which have a great impact on the simulation of water quality in the distribution network, where it deteriorates the most.…”

In this paper, several methods for the calculation of water quality evolution in drinking water distribution networks are analysed. The Lagrangian Time-Driven method has been implemented in the Epanet simulation software since version 2.0. In version 2.2, some improvements were implemented to deal with mass imbalances (Lagrangian Time-Driven improved method). However, it sometimes presents inaccuracies in calculations, especially when there are short-length pipes. To solve this problem, the implementation of the Lagrangian Event-Driven method is proposed, which provides more accurate quality results. In order to detail the differences and similarities of the results of the different methods and to determine under what conditions the results provided by Epanet are sufficiently adjusted, two practical examples have been carried out, one of them on a hydraulic model of a real network.
