A row broke out yesterday between the Prefecture of Piraeus and the Environment and Public Works Ministry over who is responsible for checking whether untreated waste is being dumped into Athens’s main river, the Kifissos. Yiannis Michas, the Piraeus prefect, told Skai Radio yesterday that the ministry, as well as the Athens Water and Sewage Company (EYDAP), are responsible for checking whether pollutants are being dumped into the water. The ministry’s general secretary, Dimosthenis Katsiyiannis, responded by saying that the prefecture is responsible for conducting the checks. He also denied that a stream which the ministry is planning to divert into the Kifissos is already heavily polluted. Residents living in the southern Athens suburbs of Moschato and Neo Faliron are opposed to the plans to divert more water into the Kifissos. The Athens and Piraeus prefectures are also against the plans to divert a sewage pipe, the Ilissos River as well as the Profitis Ilias stream into the Kifissos.
