Overall challenge – Recreational water is receiving water
3 wastewater treatment plants
75 combined sewer overflows (CSO)
58 storm water drains
50% of the flow in the river is from WWTPs

Solution - 50 mill. EUR project 2009-2013
• Infrastructure investment
− 9 retention basins
− Disinfection at WWTPs and basin
− Increased hydraulic capacity at
WWTPs
• Optimized control System
− Integrated real time
modelling/control (sewer
system/WWTP)
− Early Warning System

Model-baseret styring
Brug af dynamisk model af systemet
til optimering af styring
1. Styringsvariable optimeres over
given tidshorisont ved brug af
modellen
2. Den optimale styring
implementeres i den første del af
perioden
3. Ny optimering foretages ved brug
af nye målinger og nye
prognoser
