  2. Vacuum sewer - Wikipedia

    en.wikipedia.org/wiki/Vacuum_sewer

    Trains, aircraft, buses, and many ships with plumbing generally have vacuum systems with vacuum toilets. The lower water usage (less than a quarter of a liter per flush) [4] saves weight, and avoids water slopping out of the toilet bowl in motion. [9] Aircraft toilets may flush with blue disinfectant solution rather than water. [4]

  3. Drain-waste-vent system - Wikipedia

    en.wikipedia.org/wiki/Drain-waste-vent_system

    Generally, a toilet outlet has the shortest trap seal, making it most vulnerable to being emptied by induced siphonage. An additional risk of pressurizing a system ahead of a waste stream is the potential for it to overwhelm a downstream trap and force tainted water into its fixture. Serious hygiene and health consequences can result.

  4. Sanitary sewer - Wikipedia

    en.wikipedia.org/wiki/Sanitary_sewer

    Where it is impossible or impractical to discharge sewage from a property into a gravity sanitary sewer, a pressure sewer may provide an alternative means of connection. A macerator pump in a pumping well close to the property ejects sewage through a small diameter high pressure pipe into the nearest gravity sewer. [9]

  5. Flushing trough - Wikipedia

    en.wikipedia.org/wiki/Flushing_trough

    The flushing trough was developed by Adamsez Limited and a patent was issued to MJ Adams in 1912 for a flushing trough that used the bell siphon flushing system. [1] A further patent was issued in 1928 to AH Adams for a flushing trough that used the plate siphon mechanism, [2] marketed as the 'Epic'. Advertisements by Adamsez stated that 25,000 ...

  6. Sanitary manhole - Wikipedia

    en.wikipedia.org/wiki/Sanitary_manhole

    This can be accomplished by having a flushing manhole at the head sewer. Flushing manholes are used to store water that can be released to flush solids in the sewers. A simple design is a manhole that allows a sanitary worker to open and close a value from the ground level to perform water filling and flushing operations.

  7. Troubleshooting - Wikipedia

    en.wikipedia.org/wiki/Troubleshooting

    Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms.

  8. Hand pump - Wikipedia

    en.wikipedia.org/wiki/Hand_pump

    The installation, maintenance and repair of deep well hand pumps is more complicated than with other hand pumps. A deep well hand pump theoretically has no limit to which it can extract water. In practice, the depth is limited by the physical power a human being can exert in lifting the column of water, which is around 30 m

  9. Low-flush toilet - Wikipedia

    en.wikipedia.org/wiki/Low-flush_toilet

    A low-flush toilet (or low-flow toilet or high-efficiency toilet) is a flush toilet that uses significantly less water than traditional high-flow toilets. Before the early 1990s in the United States, standard flush toilets typically required at least 3.5 gallons (13.2 litres) per flush and they used float valves that often leaked, increasing their total water use.
