Which of the following materials is typically used for water distribution pipes?

PVC, or polyvinyl chloride, is commonly used for water distribution pipes due to several advantageous properties. It is lightweight, making it easier to handle and install compared to heavier materials like concrete or steel. PVC is resistant to corrosion and does not rust, which is particularly beneficial since water distribution systems must endure exposure to a variety of environmental conditions and water types. Additionally, PVC is cost-effective, allowing for lower installation and maintenance costs, which is a critical consideration for municipalities or companies managing water distribution systems.

The durability of PVC contributes to the longevity of water distribution systems, reducing the frequency of repairs and replacements. Its smooth interior surface also aids in maintaining water flow and reducing the risk of sediment build-up, which can hinder water quality and distribution efficiency. Overall, PVC's combination of durability, resistance to environmental factors, and economic benefit make it a widely preferred material in the construction of water distribution systems.
