Quality control - the key to sewer success
Aug 28, 2006
Well-respected pipe expert Professor Stein urges network operators to think of future generations and ensure long-term pipeline sustainability.
Most European countries are facing the shared challenge of aging sewer lines, and in the years to come, network operators across the continent will have to deal with rather extensive rehabilitation and replacement projects. It is highly important that this task is handled responsibly.
- The Sustainable Municipal Pipes Study from 2005 examines the environmental effects of leakage and defects in sewer systems and compares the performance of flexible versus rigid pipe materials – that is, plastic versus non-plastic pipes. The study looks at sewer pipe lines in Germany, Sweden and the Netherlands.
- The study found the overall defect rates of flexible pipe systems to be, on average, 20 % of the rates of rigid pipe systems. The study furthermore found that the environmental impact caused by infiltration or exfiltration for flexible pipes was only 15 % of that for rigid pipe systems.
