The project concerns the modernisation and improvement of the operation of the lake-water pumping stations of the Municipality of Kastoria. These pumping stations are an integral part of the sewerage system of the Municipal Units of Kastoria, Macedonia and Vitsi, which end up in the sewage treatment plants of Kastoria. The modernisation of pumping stations ensures the smooth operation of the sewerage networks of the lake settlements in order to protect the wider ecosystem of Lake Kastoria.
