SDG 6: Clean water and sanitation

Sustainable Development Goal

Ensure access to water and sanitation for all

Policy and sustainability plan

Circular economy


Smartness in networks and services

People innovation



To implement actions aimed at reducing water consumption in the collection and distribution processes, so as to improve water quality and reduce water dispersion

KPI 2017 2018 2023 plan objective
Linear water losses (m3/km/days) - Group average 27.6 27.8 22.5
Percentage of population equivalent without access to sewage treatment (% of total AE at 12/31/2016 in the municipalities served) 21.7% 21.7% 8%

2018 Performance


checks were carried out per million m3 of water delivered


samples taken and 284,500 parameters analysed.


m3 released for the Minimum Vital Flow shows


m3  of water was recovered within the production cycles within the BU Reti e Calore

Water resources used (thousands of m3)


  • Enhanced the  plan to reduce grid losses di riduzione delle perdite della rete idrica, 2/3 of the network were analysed
  • In the plants of the Generation BU, about 1.3 million m3 of water was recovered, equal to 31% of the supplied water.
  • A feasibility study is currently underway for a pilot project that envisages the recovery of heat, dispersed from the electrical stations in the district heating circuit by means of heat pumps, while avoiding the use of primary water

2018 Performance


GW of electric capacity installed



MWt of installed thermal energy capacity in the waste-to-energy plants


MWe of installed electricity capacity in the waste-to-energy plants



MW installed photovoltaic capacity purchase of new systems (+65 GWh of annual production)


km of water supply replaced

Elecricity generated by type of source (2018)

* For non-hazardous waste, a renewable fraction of 51% was assumed (ref. Decree of the Ministry of Economic Development of December 18, 2008). As a result, the non-renewable fraction considered was 49%.


  • Numerous activities for the monitoring and safety of dams.
  • Completed the activities of flexibility of the CCGT of Sermide and Ponti sul Mincio and started the process for the CCGT of Cassano.
  • 77% of Milan's electricity distribution network joints replaced to improve resilience.
  • IA system for the efficiency of gas preheating activities has been implemented in order to reduce gas consumption. – –The first 30 km of the sewerage system for connection to the new Valtrompia purifier have been built.
  • A2A was awarded the tender for the gas distribution of te Municipality of Milan, investments in energy efficiency and modernization of networks.
  • Work on the new Nuvolera purification plant has been completed and will come into operation in 2019.
  • The design phase for the thermal storage tanks for district heating in Brescia has been completed.
