N: 1. – black (adj): Old English blæc “absolutely dark, absorbing all light, the color of soot or coal,” from Proto-Germanic *blakaz “burned” (source also of Old Norse blakkr “dark,” Old High German blah “black,” Swedish bläck “ink,” Dutch blaken “to burn”), from PIE *bhleg- “to burn, gleam, shine, flash” (source also of Greek phlegein “to burn, scorch,” Latin flagrare “to blaze, glow, burn”), from root *bhel- “to shine, flash, burn.”
– water (n): Old English wæter, from Proto-Germanic *watar (source also of Old Saxon watar, Old Frisian wetir, Dutch water, Old High German wazzar, German Wasser, Old Norse vatn, Gothic wato “water”), from PIE *wod-or, suffixed form of root *wed- “water; wet.”
2. The waste water and excreta from water closets excluding waste water from baths, showers, handbasins and sinks.
3. The household wastewater discharged into the septic tank usually contains the toilet wastes or the so called “black water” mixed with the “grey water,” which includes the discharge from the kitchen sink, tub and shower, bathroom lavatory, dishwasher, and clothes washing machine.
4. black water: term and definition standardized by ISO.
5. The terms ‘wastewater’ and ‘sewage’ are regularly used interchangeably, however there are differences between both. In fact, ‘sewage’ is considered a subset of wastewater.
Although the term ‘sewage’ usually brings toilets to mind, it is used to describe all types of wastewater generated from domestic dwellings. There are two types of sewage: blackwater, or wastewater from toilets, and graywater, which is wastewater from all domestic sources except toilets. Blackwater and graywater have different characteristics, but both contain pollutants and disease-causing agents that require treatment.
Wastewater from non-residential sources generally require additional treatment steps than what is needed for sewage. For example, to prevent flooding of treatment plants during bad weather, stormwater should be collected separately. Screens often remove rubbish and other large solids from storm sewers. In addition, many industries produce wastewater high in chemical and biological pollutants that can burden treatment systems. Dairy plants and breweries are perfect examples of this. To combat any issues these types of wastewater sources tend to provide their own treatment or preliminary treatment to protect the main wastewater treatment system.
6. Medical definition of blackwater: Any of several diseases (as blackwater fever or Texas fever) characterized by dark-colored urine.
