    • Automatic distribution of PRVs for leakage reduction 

      Pérez Magrané, Ramon; Roca Puntí, Guillem; Grau Torrent, Sergi (Multidisciplinary Digital Publishing Institute (MDPI), 2024)
      Conference report
      Open Access
      In this work, an automatic distribution of the pressure reduction valves (PRVs) is proposed. First, a well-calibrated hydraulic model is required. The model of Manresa, a city of Catalunya in the Mediterranean area, was ...

    • Chlorine concentration modelling and supervision in water distribution systems 

      Pérez Magrané, Ramon; Martínez Torrents, Albert; Martínez del Álamo, Manuel; Grau Torrent, Sergi; Vinardell Magre, Laura; Tomàs Puig, Ricard; Martínez Lladó, Xavier; Jubany Güell, Irene (Multidisciplinary Digital Publishing Institute (MDPI), 2022-07-26)
      Article
      Open Access
      The quality of the drinking water distributed through the networks has become the main concern of most operators. This work focuses on one of the most important variables of the drinking water distribution networks (WDN) ...

    • Data setup for water distribution system supervision 

      Pérez Magrané, Ramon; Grau Torrent, Sergi; Jimenez, Victor; Martínez, Xavier; Tomas, Ricard (2017)
      Conference report
      Open Access
      The availability of on-line data coming from the water distribution systems (WDS) allows the monitoring of such critical infrastructures. Nevertheless the huge amount of data that come to the control centre implies an ...

    • Development of a graph dynamic sectorization tool using QGIS/PostgreSQL to plan and operate water distribution networks 

      Torret Requena, Xavier; Grau Torrent, Sergi; Pérez Magrané, Ramon (Universitat Politècnica de València, 2022)
      Conference report
      Open Access
      This paper presents a definition of different types of sectorization used by water distribution companies, as well as a methodology for their identification and application in the dynamic zoning of water distribution ...

    • Development of an integrated system for efficient water resource management using ESP32, MicroPython and the IoT 

      Lloys Llobet, Marina; Dragoste, Claudia; Cots, Jordi; Escobet Canal, Teresa; Grau Torrent, Sergi; Guixà, Josep Lluís (MDPI, 2024)
      Conference report
      Open Access
      This article describes the development and implementation of a water resource management system utilizing open technologies such as the ESP32 microcontroller and MicroPython. This system stands out for its low cost, high ...

    • Flow Data Based DMA Characterisation 

      Grau Torrent, Sergi; Pérez Magrané, Ramon (2019)
      Conference lecture
      Restricted access - publisher's policy
      Data in water companies have been collected since sensors (level, pressure, flow, Temperature, chlorine concentration, etc.) have been gradually introduced. Supervision and control of processes were the first drivers of ...

    • Leak detection in a DMA, a real application of flow modelling 

      Jiménez, Víctor; Grau Torrent, Sergi; Pérez Magrané, Ramon (2017)
      Conference report
      Open Access
      This paper presents a versatile methodology to calculate parameters that characterise the demand of a DMA. This parameters are used for the leak modelling so that a predictive model is built and trained with historical ...

    • Leak localisation methos using a detailed hydraulic model combined with high resolution pressure sensors applied to a real network 

      Grau Torrent, Sergi; Pérez Magrané, Ramon; Torret, Xavier; Casado, David (Universitat Politècnica de València, 2022)
      Conference lecture
      Restricted access - publisher's policy
      The objective has been the elaboration of a method of locating specific and background leaks in hydraulic models. We have worked with high-resolution hydraulic models with high resolution pressure sensors. The method has ...

    • Long and short term demand forecast, a real application 

      Grau Torrent, Sergi; Luis, Anna; Saludes Closa, Jordi; Pérez Magrané, Ramon (2019)
      Conference report
      Restricted access - publisher's policy
      Two of the main purposes of a water supply company are the operation of the network and its planning. One of the critical elements for the planning and the operation is the demand forecast. There are multiple methods for ...

    • Model calibration and leakage assessment applied to a real Water Distribution Network 

      Roma, Josep; Pérez Magrané, Ramon; Sanz Estapé, Gerard; Grau Torrent, Sergi (Elsevier, 2015)
      Conference report
      Open Access
      The use of water distribution network models depends highly on the confidence that the operators have on them. Models generated automatically from the Geographical Information System using the hydraulic equations integrated ...
