AGS supports the implementation of methodologies for the reduction of infiltration and inflow in wastewater drainage systems, thus contributing to the optimisation of environmental resources and the economic and environmental efficiency of the water utilities of the water services.

The solution includes the following activities:

Preparation of diagnostics for wastewater drainage systems

Preparation of intervention plans for the reduction of infiltration and Inflow

Performance assessment of the systems

Managing the measurement of drainage systems

Monitoring hydraulic variables

Hydraulic modelling of the network

Technical training for operational teams

Implementing technological solutions:

Monitoring hydraulic variables in real time
