The term used in the Omaha Plumbing Code to describe the fall of the invert of a sewer is known as what?

In the Omaha Plumbing Code, the term used to describe the fall of the invert of a sewer is referred to as "slope." Slope indicates the degree of incline of the sewer line, which is a critical factor in ensuring proper drainage and wastewater flow. Having the correct slope is essential for maintaining the efficiency of sewer systems, as it allows gravitational forces to assist in moving wastewater through the pipes without causing backups or sluggish flow.

The concept of slope plays a vital role in plumbing design, permitting systems to function effectively while adhering to building codes and standards. Correctly identifying and applying the slope helps prevent potential issues such as clogs or overflows, ultimately leading to safer and more reliable plumbing installations.

In contrast, terms such as grade and fall may connote similar ideas but do not specifically encapsulate the defined measurement used for sewer systems as outlined in plumbing codes. While “rise” would refer to an upward incline, it does not apply in this context of sewer design, as the focus is on downward gradients for effective waste movement.
