In low-lying communities, wastewater is often conveyed by vacuum sewer. Pipelines range in size from pipes of 125 millimetres (4.9 in) in diameter up to 280 millimetres (11 in) in diameter. Vacuum sewer systems use differential atmospheric pressure to move the liquid to a central vacuum station. [10]
A vacuum sewer or pneumatic sewer system is a method of transporting sewage from its source to a sewage treatment plant. It maintains a partial vacuum , with an air pressure below atmospheric pressure inside the pipe network and vacuum station collection vessel.
Sanitary manholes should be constructed at locations where there is a change from a simple straight sewer line. These include all junctions that combine multiple lines into one or split from one, bends, changing in elevation, changing in pipe size, and changing in pipe type.
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
The Palmer-Bowlus flume has a u-shaped cross-section and was designed to be inserted into, or in line with, pipes and u-channels found in sanitary sewer applications. [1] As a long-throated flume, the point of measurement of the Palmer-Bowlus flume is anywhere upstream of the throat ramp greater than D/2 (D=flume size).
