|The task of the project was to prepare the Project needed for the building permit and the Project for execution of the sanitation of the waterworks in Zaboršt and Zajelše. These two settlements and the area around lie southeast from Ljubljana between the river Sava and Kamniška Bistrica and the rivulet Mlinščica. The existing waterworks are cca. 40 years old. The pipes are old and don’t meet the law requirements. There are many breaks of the pipelines and therefore high costs of the repairing and loss of water. The existing household connections are old as well.
