The Sewer Research and Monitoring Station in Frejlev

The sewer research and monitoring station in Frejlev jointly financed by Aalborg Municipality and Aalborg University. The long-term measurements in the station will comply with the objectives to create the basis of knowledge on e.g.: a) long term time series containing seasonal as well as diurnal variations in dry weather flow and concentrations of pollutants, b) rainfall - runoff relationship, c) the distribution of storm water concentrations of relevant pollutants - including relationships of the level of concentration with rainfall as well as sewer system characteristics. Furthermore, the measurements can form the basis of a better understanding of transport and transportations of particulate and soluble pollutants in combined sewers including suspended and bed load characteristics and information on processes like sedimentation, resuspension and microbial transformations. Day by day operations and management of the station are performed as a teamwork between The Department of Civil Engineering and The Department of Life Science, Aalborg University.
