The development of sewage systems inevitably leads to the need for finding new types of materials for the production of sewer pipes. The old types of materials that have been applied so far have been increasingly squeezed out by the new types of materials that are produced on the basis of plastic masses. New types of pipes are produced by P.V.C. polyethylene P.E., PP polypropylene and GRP polyester. These types of metrics are increasingly extruding old types of matnirials such as clay, concrete, reinforced concrete and asbestos cement.The development of the Skopje sewerage system provides a good opportunity to analyze the development of a system that is separating and which has recently been built by old types of pipes such as clay, concrete and reinforced concrete pipes. But in the latest practice almost exclusively use new types of pipes made of plastic masses.
