In the National Water Loss Initiative, the approaches and tools developed and consolidated in the AWARE-P and iGPI projects will be adopted and implemented, in order to support: network sctorization and monitoring; analysis of large non-residential consumers; water and energy balances; analysis of night flows and consumption patterns; calculation of performance indicators, and the identification and planning of measures to improve efficiency. Alike in iGPI, this initiative aims to contribute to a reliable, organized and auditable process of calculating all the required information needed to improve management in water loss and energy control and efficiency.
