ABSTRACT Many projects have been made to reduce CSO to the harbour areas of Copenhagen but \342\200\223 according with the time schedule of the master planning \342\200\223 not all the receiving areas have the required bacteriological standards as to admit bathing guests. The public interest is intense, and an effort was made to establish the first public bathing facility in 2002. In 2003, the second facility opened. The spots were picked in areas with CSO-structures with low overflow frequency \342\200\223 approx. 1-3 per year. Because of the insecurities of the water quality, the Environmental Protection Agency (EPA) of Copenhagen, Copenhagen Energy, Sewerage Department (KE) and Danish Hydraulic Institute (DHI) have established an alarm system. The EPA has the authority and the coordinating role and is responsible for the informations. KE has the SCADA system and thereby the information of overflows from the sewer system. DHI receives the SCADA information continuously and makes prognoses with the MIKE-model of all the harbour areas. If an overflow is registered in the SCADA system, a red flag is raised in the public bath and bathing is then forbidden. The EPA has the final decision to hoist the green flag and controls estimations when bathing is allowed.
