What is a common material used for building sewer pipes?

Polyvinyl chloride (PVC) is a widely used material for building sewer pipes due to its numerous beneficial properties. One of the primary reasons for its popularity is its resistance to corrosion and chemicals, which is essential in a sewer system where exposure to various substances is inevitable. PVC pipes are lightweight, making them easier to transport and install compared to heavier materials like concrete or cast iron. Additionally, PVC has a smooth interior surface that minimizes friction and reduces blockages, allowing wastewater to flow more efficiently.

Moreover, the ease of joining PVC pipes using solvent cement or rubber gaskets enables quick installation and repairs, which is particularly valuable in municipal sewer systems that require maintenance. Overall, the combination of durability, cost-effectiveness, and ease of handling makes PVC a preferred choice for sewer piping applications.
