Which piping is acceptable for underground water distribution?

Ductile Iron is an excellent choice for underground water distribution due to its strength, durability, and resistance to various environmental conditions. This type of piping can withstand high pressure and is known for its structural integrity, making it suitable for applications where significant loads may be present, such as in industrial or municipal water systems.

Furthermore, ductile iron has a protective coating that helps prevent corrosion, which is essential for piping buried underground where it may come into contact with soil and water that can contain various corrosive elements. This longevity and reliability contribute to its widespread acceptance in underground water distribution systems.

While other materials like stainless steel, PVC, and polyolefin have their advantages in certain contexts, ductile iron's overall combination of strength, flexibility, and resistance to external factors makes it the preferred material for underground applications.
