What is the lowest point inside a pipe known as?

The lowest point inside a pipe is known as the invert. This term is used in the context of sewer and drainage systems, where the invert represents the bottom of the pipe's interior. The significance of the invert lies in its role in fluid flow; understanding the invert elevation is crucial for ensuring that gravity can effectively move water or wastewater through the system. Moreover, proper grading and pipe placement are essential to maintain adequate flow and prevent issues such as blockages or backups.

The use of specific terminology like "invert" aligns with industry standards and practices in civil engineering and water distribution fields, emphasizing its importance in designing and maintaining effective piping systems. It also aids in clear communication among professionals in the industry.
