Vocabulary

Wastewater (click here) 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 (rainwater 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.

The real danger facing most communities in the USA today is stormwater runoff. Flooding is happening in most states and communities around the USA. Planning for floods is a matter of reality and the safety of Americans come first. But, taking a look at wastewater and how it is handled is an important concept. I do believe when federal government flood maps (click here) are assessed when flooding unexpectedly occurs, they will be found to be incorrect. 

The federal maps are incorrect because the federal government never recognized the climate crisis. Those in FEMA and other US agencies required to use science and math are handicapped to realize the full understanding of the climate crisis to their work. As a result there are going to be floods in areas where the maps state they could never happen. I would think the insurance companies would sue these agencies demanding accuracy with additions of the climate crisis be included.
