What is the primary material used for sewer pipes in most collections systems?

The primary material used for sewer pipes in most collections systems is PVC (Polyvinyl Chloride) and RCP (Reinforced Concrete Pipe). PVC is widely favored in sewer applications due to its lightweight, corrosion resistance, and ease of installation. It is also resistant to many chemicals found in wastewater, making it a practical choice for long-term use in various environmental conditions.

Reinforced concrete pipe is another common choice in sewer systems due to its strength and durability, which is essential for withstanding the pressure and loads experienced in underground installations. RCP can handle high traffic loads and earth pressures, making it suitable for larger sewer projects and systems that require significant structural integrity.

Overall, the combination of PVC and RCP caters to the diverse needs and challenges faced by modern collections systems, providing reliability and longevity in sewage transportation.
