Invert level affects flow from drainage pipes. In civil engineering, the invert level is the base interior level of a pipe, trench or tunnel; it can be considered the "floor" level. [1] The invert is an important datum for determining the functioning or flowline of a piping system.
Drainage pipes should be shown with slope. For water supply, pump capacity and number of pumps will be attached as drawing file. For drainage, manhole schedule which consist of each manhole name, Invert level, Cover level, Depth are also attached as drawing file.
Critical culvert parameters in terms of fish passage are the dimensions of the barrel, particularly its length, cross-sectional shape, and invert slope. The behavioural response by fish species to culvert dimensions, light conditions, and flow turbulence may play a role in their swimming ability and culvert passage rate.
The channel is in a U shape formed by a "half pipe" as if a pipe is cut in half and left with the bottom half. The width of the channel should match the inside diameter of the inlet and outlet pipes. The lowest point of the channel is called the invert. The invert should have a slope to allow wastewater to pass through easily.
