Beregning av totalt forurensningsutslipp fra avløpssystem : optimalisering av totalutslipp i Høvringen avløpsdistrikt i Trondheim

The article presents an integrated model and some results of its application to optimise the total pollution discharge from the Høvringen wastewater system in Trondheim. The model is accommodated to the requirements of the new regulatory system for receiving water protection in Norway (total pollution discharge permit). The model shows the effect of different kind of measures to reduce the discharge of polluted water, including static measures like runoff retention, separation of storm water and sewage, waste water pumping, and dynamic measures by valve operation.
