In January 2017 the EIB-CM received an appeal against the construction of a connecting sewage channel, the sewage collector, in the City of Ljubljana part of the upgrading the wastewater collection and treatment in the municipalities of Ljubljana, Medvode and Vodice in Slovenia. The appeal was addressed at the European Commission and the JASPERS office in Vienna and referred to the EIB-CM who declared the appeal admissible as a complaint. The complainant alleges that construction is planned through a protected area for drinking water supply that violates provisions for the protection of the underground aquifer. The aquifer is close under ground level. The projected sewage channel would cross an area that has remained uninhabited due to strict law enforcement and is, moreover, a grave pollution risk also due to its design (insufficient gradient). The complainant further alleges that the projected sewage channel runs across a geological fault with permanent seismic movements.
