What is mean by invert elevation?

Invert elevation refers to the lowest inside point of a drainage pipe or channel, measured from a defined reference point, usually above sea level. It is important for ensuring proper flow and drainage in plumbing and civil engineering projects, as it helps determine the slope and capacity of the system. Accurate invert elevation measurements are crucial for preventing issues like backflow and ensuring effective wastewater management.


How do i find actual invert elevation on a sewer pipe?

To find the actual invert elevation of a sewer pipe, you can use a level or surveying equipment to measure the height of the pipe from a known reference point, such as a manhole rim or ground surface elevation. The invert elevation is calculated by subtracting the measurement from the reference point's elevation. Additionally, you may refer to construction plans or as-built drawings that typically document the invert elevations. If necessary, verify the measurements with multiple points along the pipe.

What are technical orders?

Technical orders (TOs) are official documents used by military and aerospace organizations to provide detailed instructions for the operation, maintenance, and repair of equipment and systems. They ensure that personnel follow standardized procedures and adhere to safety protocols. TOs can include various forms of documentation, such as manuals, checklists, and specifications, tailored to specific equipment or tasks. Their primary purpose is to enhance operational efficiency and ensure the reliability of systems and equipment.


Is the invert elevation of a pipe related to sea level?

Not quite. The invert elevation of a pipe is measured at the flow line which is the bottom inside of the pipe. The bottom of pipe elevation should be the bottom outside of the pipe. The difference betwen the two measurements is the thickness of the pipe wall.
