How does the performance in service of plastic pipe systems compare with other sewer pipe materials?
Plastic sewer pipes have one fifth of the number of defects compared with rigid sewer pipes.
- The above statistic is based on the findings of an extensive research project into the performance in service of existing sewer systems in Germany, Netherlands and Sweden.
- This study involved the examination of 1,800 kilometres of existing sewers using CCTV survey footage.
- All systems surveyed were less than 12 years old to ensure a like for like comparison.
- Defects were recorded in accordance with the coding system defined in EN 13508-2 "Condition of drain and sewer systems outside buildings Part 2 Visual Inspection coding system".
- Analysis of the data was conducted by the leading European consultants Stein & Partners.
- To ensure absolute objectivity the results and conclusions from the study were validated by an independent panel of European experts.
- Other findings in the report include :
- The environmental impact of an average section of plastic sewer is 15% of that for rigid pipe systems.
- When considering defects that can affect the environment (infiltration of ground water and exfiltration of effluent), defect rates in plastic sewers are on average 25% of the defect rates of rigid systems.
