What type of piping is commonly utilized for wastewater drainage?

The use of ABS (Acrylonitrile Butadiene Styrene) piping for wastewater drainage is well-established in the plumbing industry due to its unique properties that make it suitable for this application. ABS is lightweight, has a high resistance to impact and temperature changes, and does not corrode. Its smooth internal surface allows for efficient flow and reduces the potential for blockages, which is crucial in drainage systems. Additionally, ABS piping is easy to install and is often preferred for underground and above-ground drainage applications because of its flexibility in various weather conditions and environments.

It's important to consider that other materials like CPVC, PVC, and galvanized steel are used in plumbing applications, but they have specific limitations or applications that make them less suited for wastewater drainage compared to ABS. For example, while PVC is also frequently used in plumbing for drainage, it doesn't possess the same impact resistance as ABS, especially in cold temperatures. Galvanized steel can corrode over time when exposed to wastewater, and its weight and difficulty in installation may hinder its use in specific drainage situations. Thus, ABS remains the most common choice in many drainage scenarios, making it the correct answer for this question.
