The continuity of the water service

The water network control activity index is expressed as a percentage of the network inspected for leaks.

On the whole, in 2017 over 9,300 kilometres of network were inspected by the Group, (including over 4,000 kilometres inspected using innovative satellite leak detection technology) amounting to 26.8% of the total network. In Emilia-Romagna the organization of the leak search activity was based on a criticality analysis in terms of network losses, breakage indexes of the pipes and possible issues concerning the availability of water resources (in particular during the summer). Thanks to the satellite-based leak search technology, 100% of the network in Trieste was inspected; the operation will be replicated for Padua in 2018.

The index of the status of the water network is expressed as the number of breakages per kilometre of network and has slightly increased for Hera Spa, compared to last year. The meter replacement figure is also up (15,357 in 2017 against 11,149 in 2016).
