Bäume und Leitungen - untersuchungen zur Einwurzelung in moderne PVC- und Betinabwasserleitungen

Functional sewage systems and aesthetic tree environments are both essential elements of modern urban construction. However, during the greater part of the 20th Century, urban environments were designed without regard to how trees and sewage pipes were positioned in relation to each other. The penetration of tree roots into sewage pipes has therefore become a problem that is creating an ever-increasing financial burden for urban society. To be more effective at preventing root intrusion into sewage systems, today’s planners and constructors of urban environments must improve their knowledge, be aware and have an understanding of growing site conditions and their significance, of variations between tree species in their demands on growing site, of vulnerable points in the sewage system, of variations between tree species in their capacity to penetrate vulnerable points of sewage pipelines and of significance of tree placement in relation to the type, depth and placement of pipelines
