What is the standard material used for water service lines?

Copper is widely recognized as the standard material for water service lines due to its excellent reliability and durability. It has a long history of use in water distribution systems because it is resistant to corrosion, which minimizes the risk of contaminants leaching into the water supply. Copper also has inherent antimicrobial properties that help prevent the growth of bacteria, making it a safe choice for drinking water. Additionally, it is flexible enough to withstand ground movement and temperature changes, an important characteristic for enduring performance in varying environmental conditions.

While other materials such as polyethylene, PVC, and steel are used in certain applications within the water distribution system or in specific regions, they do not possess the same extensive benefits as copper for service lines specifically. Polyethylene, for example, is often used for flexibility and resistance to certain environmental factors but may not offer the longevity that copper provides. PVC is typically utilized for its cost-effectiveness and chemical resistance but is not suitable for high-temperature applications. Steel, while strong, is prone to corrosion unless properly coated, making it less desirable for long-term use in drinking water systems.
