Improving wastewater quality is necessary to ensure healthy ecosystems as well as human and animal health. At the same time, wastewater management - the discharge, collection, and purification of water - represents a high cost for municipalities and municipal service providers. To address challenges for ensuring wastewater quality as well as increasing water scarcity, municipalities can turn to various smart technologies. In wastewater treatment, sensors and data analysis can improve the efficiency of processes and thus save costs and energy. Resources are freed up, for example, for the modernization of plants. Awareness campaigns directed at citizens are also an effective means of improving wastewater quality. Smart wastewater networks provide information on which types of pollution are a problem.
In order to create globally sustainable structures, the member states of the United Nations have set themselves 17 goals by 2030, which are set out in the 2030 Agenda for Sustainable Development.
