2. Sewage pumping - Wikipedia

   en.wikipedia.org/wiki/Sewage_pumping

   Three classes of submersible pumps exist: Smaller submersible pumps, used in domestic and light commercial applications, normally handle up to 55 millimetres (2.2 in) spherical solids and range from 0.75 to 2.2 kilowatts (1.01 to 2.95 hp). Larger submersible pumps, handle 65 millimetres (2.6 in) and larger solids and normally have a minimum of ...

3. Submersible pump - Wikipedia

   en.wikipedia.org/wiki/Submersible_pump

   A 0.75 HP bore-well submersible pump which had been used to pump groundwater One style of submersible pump for industrial use. Outlet pipe and electrical cable not connected. A submersible pump (or electric submersible pump (ESP) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in ...

4. Submersible mixer - Wikipedia

   en.wikipedia.org/wiki/Submersible_mixer

   The mixer is being installed in an anoxic sludge tank at a sewage treatment plant. A submersible mixer is a mechanical device that is used to mix sludge tanks and other liquid volumes. Submersible mixers are often used in sewage treatment plants to keep solids in suspension in the various process tanks and/or sludge holding tanks. [1]

5. Pumping station - Wikipedia

   en.wikipedia.org/wiki/Pumping_station

   When the sewage level rises to a predetermined point, a pump will be started to lift the sewage upward through a pressurized pipe system called a sewer force main if the sewage is transported some significant distance. The pumping station may be called a lift station if the pump merely discharges into a nearby gravity manhole. [4]

6. Sewerage - Wikipedia

   en.wikipedia.org/wiki/Sewerage

   Sewerage (or sewage system) is the infrastructure that conveys sewage or surface runoff (stormwater, meltwater, rainwater) using sewers. It encompasses components such as receiving drains , manholes , pumping stations , storm overflows, and screening chambers of the combined sewer or sanitary sewer .

7. Vacuum sewer - Wikipedia

   en.wikipedia.org/wiki/Vacuum_sewer

   Sewers can be laid in flat terrain, and parts may flow uphill (within limits). A saw-tooth profile keeps sewer lines shallow; [5] in frost-free climates, trench depth can be about 1.0 – 1.2 m. By contrast, gravity sewers need a monotonically falling slope of at least 0.5 - 1.0%, which can mean that expensive trenching and pumping stations are ...
