Sanitation is a vital yet too often ignored challenge, and the durability of buried sewerage system materials is rarely considered by municipalities. The city of Malmö, Sweden, conducted a 6 year test programme to assess the resistance of sewerage pipes materials to tree root penetration. The research marked a step change for the sustainability of these pipe systems by using welded PP-HM materials. Malmö’s analysis showed how closely economic, social and ecological benefits are linked together for a sanitation solution.
By preventing the contamination of clean water and the environment, sewage disposal dramatically reduces the outbreaks of waterborn diseases. In fact, sanitation was ranked by the British Medical Journal readers as the most important medical advance in the past 150 years. Yet the importance of keeping the buried sewerage system in good shape is often ignored by most people. Enhancing the performance and overall sustainability of sewage networks can deliver environmental, social and economic benefits to the communities.
Because of its exceptionally green design, Malmö is known as Sweden’s ‘Park City.’ However, while providing an attractive and healthy environment, over the years, the benefits of beautiful surroundings also had a growing and hidden cost to the community.
