What material is typically used for the distribution pipes in a septic system?

Plastic is commonly used for the distribution pipes in a septic system due to its durability, resistance to corrosion, and lightweight nature, which makes it easy to handle and install. Plastic pipes, typically made from materials like PVC (Polyvinyl Chloride) or HDPE (High-Density Polyethylene), are not only cost-effective but also offer a smooth interior surface that helps reduce the risk of clogs and blockages as wastewater flows through them.

In addition to being less prone to leaking compared to other materials, plastic pipes are resistant to chemical degradation from the various substances they may encounter in wastewater. This makes them a reliable choice for ensuring the long-term functionality of septic systems. The selection of plastic over metals or organic materials enhances the overall efficiency and longevity of the septic system.
