STATEMENTS
• Digitization is a very lengthy process
• Digitization of «function» and «silent knowledge» is the key
• The real challenges of digitization is not technology
• A full functional GIS system is the base for digitization
• ICT / Data security should not prevent the «use-value» of the information
=> Complexity, Integration and Holistic
Why Holistic?

How To ....
Proactive reaction & optimize operation
Locate and eliminate vulnerabilities
Fact based decision tool
Training
..access, integrate and analyze all data using a holistic approach?
How can Online Hydraulic Modelling/ system contribute?

«Silent Knowledge» retires
Online Project • Using Aquis (by Schneider Electric) + HOMIS as the online system
• Pilot project characteristics- Maximum flow ~ 1500 m³/h - 60,000 inhabitants- 5,660 pipes – 246 km- 160 SCADA tags (online measurements)- Update frequency 10 minutes
• Pilot project implemented during 2015=> evaluation (completed 2016) => full implementation (2017 - 2020)
• Full scale project – Oslo (2017 – 2020)- Maximum flow ~ 6500 m³/h - 700,000 inhabitants- 1550 km pipe-length and 70 DMA- 900 SCADA tags (online measurements)- Update frequency 10 minutes
