06/11/2024A recent study presented at the 16th International Conference on Urban Drainage (June 2024) highlights the environmental advantages of PVC pipes in sewer network renovation. The research compared Global Warming Potential (GWP) and Cumulative Energy Demand (CED) for PVC and high-density polyethylene (HDPE) across two renovation methods: the traditional Open-Cut Method (OCM) and the Pipe Bursting Method (PBM).
Key findings include:
- Lower GWP and CED for PVC: PVC exhibited significantly reduced environmental impacts compared to HDPE.
- Efficient Renovation Methods: PBM, when paired with PVC, reduced GWP and CED by approximately 50% compared to OCM, highlighting the benefits of trenchless technology.
PVC liners: a safe and sustainable solution for trenchless sewer repair
In addition, polyvinyl chloride (PVC) liners are transforming trenchless sewage repair. This no-dig method involves pushing a compressed PVC liner into damaged pipes, where it is expanded with steam to create a tight, durable seal. The result is essentially a new PVC pipeline with an extended lifespan. Compared to other liner materials, PVC offers safer installation by avoiding exposure to harmful chemicals.
The availability of bio-attributed PVC liners further enhances sustainability by offering an solution with an even lower environmental impact.
