Types of wastewater

Ocean dumpingWastewater comes in three main types namely Blackwater, Graywater and Yellow water.


Blackwater

This is wastewater that originates from toilet fixtures, dishwashers and food preparation sinks. It is made up of all the things that you can imagine going down the toilets, bath and sink drains. They include poop, urine, toilet paper and wipes; body cleaning liquids, anal cleansing water and so on. They are known to be highly contaminated with dissolved chemicals, particulate matter and is very pathogenic.

Graywater
This is wastewater that originates from non-toilet and food fixtures such as bathroom sinks, laundry machines, spas, bathtubs and so on. Technically it is sewage that does not contain poop or urine. Graywater is treated very differently from Blackwater and is usually suitable for re-use.

Yellow water
This is basically urine collected with specific channels and not contaminated with either blackwater or graywater.

Sources of wastewater

Domestic Sewage
This includes all wastewater generated by home dwellings, public restrooms, hotels, restaurants, motels, resorts, schools, places of worship, sports stadiums, hospitals and other health centers, apartments and the like. They all produce high volumes of wastewater.

Non-sewage
These include water from floods (stormwater), runoff (rain water running through cracks in the ground and into gutters), water from swimming pools, water from car garages and cleaning centers. They also include laundromats, beauty salons, commercial kitchens, energy generation plants and so on.

Wastewater is also generated from agricultural facilities. Water used for cleaning in animal farms, washing harvested produce and cleaning farm equipment.
