What does a soil pipe convey?

A soil pipe specifically conveys sewage, which is the waste produced from toilets and similar plumbing fixtures. It is designed to handle human waste and is a crucial part of the plumbing system in residential and commercial buildings.

The design and function of soil pipes are tailored to ensure that they can efficiently transport the solids and liquids contained in sewage, preventing blockages and ensuring the sanitary disposal or treatment of waste.

Other options, while they refer to important types of drainage, do not accurately describe the primary function of a soil pipe. Rainwater typically flows through gutters and downspouts, while gray water refers to wastewater from sinks, showers, and other sources, which are handled by different types of drainage systems. Therefore, the primary specialty of a soil pipe is its role in conveying sewage.
