Furthermore, one of the main causes of the deficient control of the UWwSs is the lack of data in each subsystem and the lack of coordination within institutions to share the information and take decisions based on it. Even though, there are sensors available for water quantity and water quality, advanced microprocessors and hydroinformatics tools for information management, the lack of information is still one of the causes of the poor control of UWwSs. One way to tackle these problems is by defining clear and documented guide lines that allow the education institutions to fill the gab in the transfer of knowledge and technology to the practitioners in charge of design, operate and manage the UWwSs. Thus the aim of Data Net project is to develop guidelines and educational material that can be used to fill the knowledge gaps in data acquisition and data exchange used to control UWwSs. The starting point of the project is the recover of experience in the field based in the diagnosis of two urban wastewater systems, one in Cali - Colombia and the other correspond to Gouda in the Netherlands. This report presents the results of the diagnosis of the existing monitoring networks for each component of the UWwS of Gouda. The urban wastewater system was selected within the region of influence of Rijnland Water Board. In order to select the system 12 communities where analyzed and the Urban Wastewater System of Gouda was found as the must appropriated system to develop the research. From the institutional point of view is a system in which its optimization is of relevant interest to Rijnland Water Board and the Municipality. There is an interdisciplinary group confronting the problems of the system with an integrated vision, although the focus is more to optimize the performance of the sewer system, jointly measures are been considered. Within those prioritized measures the information is one on the top ten. The diagnosis of the monitoring system status includes an inventory of the UWwS components, and inventory of the existing monitoring networks focusing in answer the questions: who is in charge of monitoring?, what is measured?, where? And when?. Also the flow of information within the institutions is assessed considering how data is transmitted, quality controlled, stored, retrieved and used. The diagnosis of Gouda, shows the need for increase the awareness of practitioners in advanced sensors for automatic monitoring of water quality gauges, improve the transmission of data to the operational level, improve the processing and generation of information useful for control purposes and the need for improve the sharing and integration of information from different institutions.
