Tree Roots in Sewer Systems in Malmo, Sweden

Three sites with root intrusion problems in the City of Malmo were inspected to find different solutions to the problems. All sites had high maintenance costs due to the roots. Alternative measures for each site were selected. Each site was treated differently depending on the technical, aesthetical, cultural and economical values. At one site, pipes were relined, at another the trees were replaced with less aggressive species and at the third a decision is yet to be made.
