ESTIMATION OF QUALITY AND POLLUTION LOAD OF COMBINED SEWER OVERFLOW DISCHARGE.
Summary, in English
The relative effect of combined sewer overflow (CSO) discharge into receiving waters has increased during the last decades due to improved efficiency at treatment plants. In association with the rapid urbanization in the sixties and early seventies, new areas were connected to old sewer networks with limited capacity, leading to an increase in overflow volumes and, thus to an increase in pollution load. In order to develop a responsible urban water quality management policy we must be able to describe CSO in terms of quality and quantity. To elucidate such problems extensive measurements were carried out in the city of Malmo with quality sampling and simultaneous flow measurements. This paper presents different aspects on the quality of CSO discharge and different available methods for calculation of the pollution load.
