2. Sanitary engineering - Wikipedia

   en.wikipedia.org/wiki/Sanitary_engineering

   An example of a wastewater treatment system. Sanitary engineering, also known as public health engineering or wastewater engineering, is the application of engineering methods to improve sanitation of human communities, primarily by providing the removal and disposal of human waste, and in addition to the supply of safe potable water.

3. Sanitation worker - Wikipedia

   en.wikipedia.org/wiki/Sanitation_worker

   Sanitation workers carrying out manual pit emptying (in Durban, South Africa) with personal protective equipment. A sanitation worker (or sanitary worker) is a person responsible for cleaning, maintaining, operating, or emptying the equipment or technology at any step of the sanitation chain.

4. Septic drain field - Wikipedia

   en.wikipedia.org/wiki/Septic_drain_field

   Septic drain fields, also called leach fields or leach drains, are subsurface wastewater disposal facilities used to remove contaminants and impurities from the liquid that emerges after anaerobic digestion in a septic tank. Organic materials in the liquid are catabolized by a microbial ecosystem.

5. Wastewater treatment - Wikipedia

   en.wikipedia.org/wiki/Wastewater_treatment

   Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges. [5]

6. Waste management - Wikipedia

   en.wikipedia.org/wiki/Waste_management

   Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment.

7. Mound system - Wikipedia

   en.wikipedia.org/wiki/Mound_system

   If the soil permeability is too low, the liquid is not absorbed fast enough. If the soil permeability is too high or is exposed to fractured bedrock, the wastewater reaches the water table before the biofilm has time to purify the water, contaminating the aquifer. In either situation, the mound system provides an ideal habitat for the biofilm ...

8. Sanitary sewer - Wikipedia

   en.wikipedia.org/wiki/Sanitary_sewer

   The maintenance requirements vary with the type of sanitary sewer. In general, all sewers deteriorate with age, but infiltration and inflow are problems unique to sanitary sewers, since both combined sewers and storm drains are sized to carry these contributions.

9. Sewerage - Wikipedia

   en.wikipedia.org/wiki/Sewerage

   The main interest of dry shotcrete is the capacity to pump the mortar over a long distance and this is needed when the access points are distant. Perhaps the longest dry shotcrete distance is a job site in Australia in 2014, where 100% calcium aluminate mortar was air transported over 800 meters before being sprayed. The main drawback with dry ...
