The Municipality of Noia implements “smart water” technologies in the context of the Aquamundam project

The entities Augas de Galicia (Waters of Galicia), Galicia Institute of Technology (GIT) and the Municipality of Noia have been moving forward with the work of implementing a sustainable management system for the municipality’s entire water cycle

The collaboration of the Municipality of Noia with the partners of the Aquamundam project, financed by the POCTEP program, has allowed the implementation of geographic information technologies (GIS) and Internet of Things (IoT), aimed at achieving a sustainable management of the entire water cycle. One of the three pilots of the Aquamundam project, a European-wide initiative, will make available to small populations, technological solutions, typical of large smart cities.

The GIT coordinates the development and implementation of a solution that will enable a better patrimonial management of the infrastructures, the timely resolution of incidents through an agile mathematical model, among other benefits, such as:

  • Consultation of the characteristics of the geo-positioned components of the drinking and collected water distribution networks and waste water treatment;
  • IoT tools for processing the data collected through the network sensors, allowing a real-time knowledge of the operation parameters, configuration of alerts and graphical analysis of all information;
  • Management of incidents related to water services, including the traceability of the entire resolution process;
  • Connection with software for modelling the supply and sanitation network, in order to characterize the current performance of the network, as well as to study its operation in the face of other contexts, such as the extension or improvement of existing systems;
  • Cost analysis and purchasing module associated with the management of water services, with tools for summary and identification of the main investments.

Analysis of Noia’s sanitation and supply networks

The municipality of Noia and the consortium of the Aquamundam project, of which the GIT and the Augas de Galicia entity are part, have been working, in recent months, on digitizing the information collected in the municipal sanitation and supply networks. The sanitation network was inspected and mapped under the direction of the Augas de Galicia, reaching more than 60 km of examined network.

From this collected information, mathematical models were generated to study the current functioning of the collector network and propose measures to improve it. Also, the municipality’s supply network was digitized with the collaboration of the municipality’s technicians, which simplifies the consultation and update of data on the network components and provides greater agility in the operation and maintenance of infrastructure.

In the last few months, test studies were carried out to install sensors that measure, in real time, the functioning of the system, and send its data to the web platform for geographic information, Aquamundam.

Pilot of smart water meters

In the last few months, an IoT network has been installed that will connect sensors to the Aquamundam platform. Among these sensors, we highlight the domestic meters with remote reading stand out, for which a coverage test was carried out in early November. The installation of this equipment will facilitate reading the water consumption without the need to access the interior of the houses, which is of particular relevance in the current pandemic situation due to COVID-19.

These counters also allow you to obtain more daily information and help to identify potential malfunctions, such as leaks and ruptures, more quickly. This pilot was implemented in the historic Center of Noia, and will serve to verify, in a real context, the advantages that this equipment offers to contribute to a better provision of the supply service.

A local experience with global reach

The Noia pilot complements other studies carried out under the same project in cities in the north of Portugal and in Castile and León, thus allowing the Aquamundam project to focus, not only on the management of the water cycle, but also in exchanging experiences and good practices to achieve the most sustainable maintenance of this scarce and precious asset. Likewise, Aquamundam is a project in line with the UN’s Sustainable Development Goals (SDGs), whose Goal 6 is precisely “Clean water and sanitation”, promoting equitable access to drinking water and promoting preventive measures that prevent your waste.
