Undue inflows pose a critical challenge to wastewater systems. These refer to volumes of water that enter public wastewater drainage networks in an uncontrolled manner – either from precipitation (direct inflow) or via groundwater infiltration (indirect inflow). This phenomenon undermines infrastructure efficiency, increases both operational and capital costs for drainage networks and wastewater treatment plants (WWTPs), and hinders the sustainability of sanitation systems.

Mitigating these impacts requires a thorough assessment of the scale and origin of each component of undue inflows. It is within this context that the W2DS project was established, aiming to support managing entities (EG) in the smart monitoring and efficient management of their wastewater drainage networks, enabling the implementation of the most appropriate measures to address this issue.

The W2DS project focuses on flow rates monitoring inside inspection chambers, allowing EG to assess the quantity and quality of water entering the system inappropriately. Moreover, the solution enables a distinction between direct and indirect inflows components, supporting more targeted interventions. All field data are transmitted remotely and processed through a digital platform developed under the project, providing EG with clear, reliable, and real-time information.
