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?

«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
