Water Colours

In my world, people frequently talk about different types of water, in colours. If you ever hear or read the terms, this is what they mean:

Blue water is freshwater found on the earth’s surface (rivers, lakes, swamps and streams), in aquifers (groundwater) and in glaciers. Of all the water in the world, blue water accounts for approximately 3%, however only less than 1% of the 3% is easily accessible.

Green water is found in the soil’s pores after precipitation (rain) or irrigation. Yes, soil has pores.:)… The water helps in dissolving nutrients for the plant’s uptake.

Grey water is the wastewater found after domestic use (bathing, laundry and even washing dishes) or agricultural use because of pesticides and/or the nutrients from fertilizers. Grey water can be recycled and reused for domestic use and irrigation.

The final and least exciting is,

Black water AKA Sewage is wastewater that contains feaces (that sounds disgusting, huh? especially since I’m thinking of it in Swahili)…wastewater that contains feacal matter (sounds better).

Have a colourful week! 😀
