Grey Water Definition 3 Easy Colour Codes

Grey Water Definition 3 Easy Colour Codes

Grey water definition 3 easy colour codes. Save potable water. Good enough to drink. Then, water classification by colour is necessary for effective use of conservation methods. The definition of grey water. Three colours for the types. A system to identify and use resources appropriately.

Easier to clean up. Know what we can use and what we cannot use. Avoid contamination. Keep each type separate. Save the good stuff for our own consumption. Find other uses for non-drinking. Some grey water may be good enough to water plants. In fact, washing cars on your lawn is a tip for homeowners sustainable gardening.

Efficient use of water resources. Know the various types. What they are. How they can be used. Conservation of our potable water supply. Preservation of land that supplies drinking water.

Potable Water Supply

Ecofriendly living Millennials. Students studying in school. Employees working from home and on site. Sustainable water usage. At home when turning on faucets. In the yard harvesting rain. Outside to keep contaminated liquids away from sewers and drains. When our actions affect potable water. Taking a shower. Washing our hands. Brushing your teeth.

Potable water supply is opposite of grey water definition. Free from pollution is potable. Many do not have access. Others have been exposed to contamination that causes immediate harm. Also, industrial chemicals are known to cause higher cancer rates in nearby residents.

Filtering the sea to make it drinkable is being researched. Restricted use is under way in some areas. Efficient use is why we have the colours.

Water Classification

Water classification for fresh potable H20. Thus, our limited supply. 3% is fresh. 1% of potable is accessible. So, classify with colour.

Classes of H20 exist. In any event, we are dealing with our own consumption. Classification colours. Potable water supply.

Classification colours are standard. Hence, correct to use. It follows, others use the code. As a result, we know how to get the most out of it. Therefore, use it efficiently.

  • Blue irrigated from lakes and ground.
  • Green rain.
  • Grey includes waste.


Blue is as it should be. Clean for drinking. Safe for human consumption. Sometimes referred to as the open sea. Here, this classification is different. Sea is not potable. Cannot drink it. Blue water is drinking water for classification.


Green is generally good to use. Air quality can make bad. Rain is fresh. It follows, we collect and harvest. Soil water is green. Comes from the rainfall. Plants use it.

Grey Water Definition

Grey water definition is previously used. Can be contaminated. Also, known to get into municipal supplies. Grey is treated sewage, storm water, stuff like that. Moreover, bath, sink, or shower. Black water is untreated sewage. Not safe for consumption. Needs treatment. Bad. No good.

And so, colour codes tell us how to. Accordingly, they are intuitive. Thus, associated with different uses. Drink. Use, Avoid. For example, public waterways are grey.

In any event, we can take a lot of action. To illustrate, sewer drainage is reused. Thus, we clean it. And so, no littering. Also, reuse green water for non-consumption.

There are many conservation techniques. Use less more efficiently is how to use the colour classifications. That way, we know what type we are dealing with.

Throw away wastewater. Use less harmful soaps and chemicals. Going forward, we should keep the colour code in mind. Reuse as much as possible. Drink good, clean, fresh water. Enjoy the benefits. Cleanse our bodies with it. We are lucky to have it.
