Which material is often chosen for its durability in water distribution pipes?

The choice of PVC (Polyvinyl Chloride) for water distribution pipes is often based on its remarkable durability and resistance to corrosion. Unlike metals such as lead, which can corrode and pose health risks, or asphalt, which may not have the same structural integrity and longevity, PVC is designed to withstand the pressures and environmental factors associated with water distribution.

PVC is lightweight yet strong, making it easier to handle and install. It also has a long lifespan, often lasting for several decades without significant degradation. Additionally, PVC is resistant to a variety of chemicals and does not rust or degrade like metal pipes, further contributing to its durability in water systems.

In contrast, plastic film does not provide the same structural strength needed for water distribution and is not suitable for pressurized systems. Thus, the selection of PVC aligns with the requirements for a long-lasting and reliable water distribution infrastructure.
