� In 2019, the Hera Group partnered with Israeli startup Kando to develop a smart system made up of control units placed at strategic points in the sewer network, capable of continuously monitoring the level of pollution in the networks in real time. This new system of control units instantly reports polluting events, often of industrial origin, and provides information to help identify their source. The pilot project on the Castelnuovo Rangone network in the Modena area, which started in 2019, reduced the concentration of significant pollutants found in wastewater by 50%, and further reduced energy consumption. In 2020, the project was extended and is currently also being implemented in Sassuolo. The aim of the project, which is included in the business plan, is to implement and monitor �critical� urban areas in terms of the quality of treated wastewater or sewage sludge.
