Qualitative short and long term result indicators
Reliable calculation of water losses, frequent access to detailed data and data security
Capacity building of Water Operators, simple software and easy integration into the WSN Application of innovative tools and methodological approach in the whole water supply network Highlight the importance of quantifying water losses in high touristic areas
Long term cost savings
Avoiding billing errors that end in consumers complaints
Decision-making based on reliable data and not on ' estimates ' or ' knowledge ‘or ‘ experience '
Better overall management of drinking water (consumption profiles per household day, period, region, etc.) Socially fair drinking water pricing in compliance with WFD Next Steps
• Application of the integrated monitoring system to the entire WSN of 1 Igoumenitsa’s water utility
2 • Redefinition of the existing DMAs and PMAs
• Application of an integrated monitoring system of water consumption through the replacement of obsolete water meters with smart water meters 3 of high metering accuracy
• Connection of the metering consumption system with the Central Control 4 Station through the utilization of specialized software
• Establishment & training of water operators using appropriate hardware and software for the system’s operation improvement (Maintenance Planning and 5 Asset Management) & the monitoring of appropriate indicators
• Decision Support Tool for the Development and Infrastructure Master 6 Planning Prioritization (short-term & long-term, ie pipeline replacement plan)
• Connection with existing accounting systems for the development of Full 7 Water Cost Recovery strategy and pricing policy according to WFD 60/2000 Next Steps NRW reduction issues and challenges to ensure Non-Intermittent Water Supply
