The second method is to use a drop manhole. A drop manhole is a junction manhole that is equipped with a structure to allow liquid and solids in the wastewater to smoothly drop down to the channel inside the manhole. There are two types of drop manholes, vortex and plunging drop manholes. [26] In a vortex drop manhole, the flow from a higher ...
In water supply system drawing there will be hot water piping and cold water piping and hot water return piping also. In drainage system drawings there will be waste piping, Soil piping and vent piping. The set of drawing of each system like water supply, drainage etc is consist of Plans, Riser diagram, Installation details, Legends, Notes.

A manhole (utility hole, maintenance hole, [1] or sewer hole) is an opening to a confined space such as a shaft, utility vault, or large vessel.
The pumping station may be called a lift station if the pump merely discharges into a nearby gravity manhole. [4] From here the cycle starts all over again until the sewage reaches its point of destination—usually a treatment plant. By this method, pumping stations are used to move waste to higher elevations.
A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing. Usually, a number of drawings are necessary to completely specify even a simple component. These drawings are linked together by a "master drawing." This "master drawing" is more commonly known as an assembly drawing.
Parshall flumes require a drop in elevation through the flume. To accommodate the drop in an existing channel either the flume must be raised above the channel floor (raising the upstream water level) or the downstream channel must be modified. As with weirs, flumes can also have an effect on local fauna. Some species or certain life stages of ...
Shafts are often entered through a manhole and closed by a manhole cover. They are constructed for a number of reasons including: For the construction of a tunnel; For ventilation of a tunnel or underground structure, aka ventilation shaft; As a drop shaft for a sewerage or water tunnel
An exploded-view drawing is a diagram, picture, schematic or technical drawing of an object, that shows the relationship or order of assembly of various parts. [1]It shows the components of an object slightly separated by distance, or suspended in surrounding space in the case of a three-dimensional exploded diagram.
