What material is commonly used for modern water distribution pipes?

Modern water distribution systems predominantly use PVC (polyvinyl chloride) plastic for their pipes due to its numerous advantages. PVC is lightweight, making it easy to transport and install, which reduces labor costs during installation. It is also resistant to corrosion and has a long service life, which enhances the durability of the water distribution system. Additionally, PVC has a smooth interior surface that minimizes friction loss and better facilitates the flow of water compared to materials like steel or wood.

Furthermore, using PVC helps to reduce the risk of contamination since it does not leach harmful substances into the drinking water, unlike lead pipes. The adoption of PVC in water distribution systems reflects a shift towards safer, more efficient, and cost-effective materials that meet modern public health and infrastructure requirements. This is why PVC plastic is the preferred choice in contemporary water distribution systems.
