  2. Palmer-Bowlus Flume - Wikipedia

    en.wikipedia.org/wiki/Palmer-Bowlus_Flume

    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).

  3. Hydrostatic test - Wikipedia

    en.wikipedia.org/wiki/Hydrostatic_test

    Hydrostatic testing is the most common method employed for testing pipes and pressure vessels. Using this test helps maintain safety standards and durability of a vessel over time. Newly manufactured pieces are initially qualified using the hydrostatic test. They are then revalidated at regular intervals according to the relevant standard.

  4. Sanitary manhole - Wikipedia

    en.wikipedia.org/wiki/Sanitary_manhole

    Exfiltration testing uses water to fill up a manhole and measurements are taken to detect leaks. In a modern time, vacuum testing is performed to check integrity of manholes and identify for leaks. [32] Another common testing method is smoke testing. In this method, sandbags are used to seal a sewer section, then smoke is pumped into a manhole.

  5. Leak detection - Wikipedia

    en.wikipedia.org/wiki/Leak_detection

    Methods of detection include hydrostatic testing, tracer-gas leak testing, infrared, laser technology, and acoustic or sonar technologies. Some technologies are used only during initial pipeline installation and commissioning, while other technologies can be used for continuous monitoring during service.

  6. Smoke testing (mechanical) - Wikipedia

    en.wikipedia.org/wiki/Smoke_testing_(mechanical)

    In plumbing a smoke test forces non-toxic, artificially created smoke through waste and drain pipes under a slight pressure to find leaks. [4] Plumes of smoke form where there are defects. This test can be performed when the plumbing is brand new, but more often it is used to find sewer gas leaks that may plague a building or an area. [4]

  7. Pipeline video inspection - Wikipedia

    en.wikipedia.org/wiki/Pipeline_video_inspection

    With modern video equipment, the interior of the pipe may be inspected - this is a form of non-destructive testing. A small diameter collector pipe will typically have a cleanout access at the far end and will be several hundred feet long, terminating at a manhole. Additional collector pipes may discharge at this manhole and a pipe (perhaps of ...

  8. Sanitary sewer - Wikipedia

    en.wikipedia.org/wiki/Sanitary_sewer

    A sanitary sewer is an underground pipe or tunnel system for transporting sewage from houses and commercial buildings (but not stormwater) to a sewage treatment plant or disposal. Sanitary sewers are a type of gravity sewer and are part of an overall system called a "sewage system" or sewerage .

  9. Infiltration/Inflow - Wikipedia

    en.wikipedia.org/wiki/Infiltration/Inflow

    Groundwater entering sanitary sewers through defective pipe joints and broken pipes is called infiltration. [4] Pipes may leak because of careless installation; they may also be damaged after installation by differential ground movement, heavy vehicle traffic on roadways above the sewer, careless construction practices in nearby trenches, or degradation of the sewer pipe materials.
