With the 917/2017/R/idr Resolution of 27/12/2017, the Regulatory Authority for Energy, Networks and the Environment (ARERA) has introduced the new Regulation of the Technical Quality of the Integrated Water Service (RQTI).

The new RQTI introduces a set of performance indicators about six themes, that Italian utilities must measure and improve: water leaks, water service interruptions, supplied drinking water quality, adequacy of the sewage system, sludge disposal in landfills and quality of wastewater effluents.

For each theme, ARERA requires the implementation of a plan to improve the indicators, through an incentive mechanism based on bonuses and penalties.


The RQTI introduces new important competitiveness and efficiency challenges that, however, require the adoption of new technical solutions, in order to face the needs of performance improvement. In this sense, the RQTI represents a great opportunity to adopt innovation programmes in the utility investment planning.


The aim of the module is to present the contents of the new RQTI, analysing the complex system of prerequisites, specific and general standards, macro indicators and simple indicators, incentive mechanisms, as well as the potential impacts that will have for the utilities.

Secondly, for each of the six themes, some examples of innovative technical solutions currently available on the market and allowing to improve the indicators will be presented. The proposed technologies will be chosen among those of relatively recent development, but which have already found applications at international level with promising results.



  • Presenting the contents of the new RQTI introduced by ARERA and analyse the impacts for the water utilities
  • Showing examples of technologies available on the market, at national and international level, which can help to improve the indicators
  • Encouraging discussion, comparison and sharing of experiences among participants


Target audience

  • Technicians, specialists and innovation managers working in water utilities
