Gray Water: An Overview

Gray water is defined as any water used for washing purposes in the home.  It includes water from dishwashers, sinks, washing machines, and showers, but excludes water from toilets.  While people have gross impressions of the water and think that it goes straight to sewage plants along with societ's other detriment.  However, there are actually several benefical uses of gray water.

 

One obvious use of gray water is the possibility of reusing the water for other things around the house.  One common application is redirecting the gray water into toilets.  Not only will this reduce a person's water bill, but also it will reduce the demand for fresh water.  This lessen's the strain on the environment's water resevoirs and ultimately benefits the environment.  Reusing gray water for plumbing also reduces the volume of water that must be treated, since the water originally from both gray water and toilet water is now consolidated into one volume unit.

 

Another perhaps less obvious use of gray water is for irrigation of plants and yards.  Some may think that the chemicals present in gray water cannot possibly be healthy for the plants.  However, studies have shown the opposite.  Some chemicals in gray water contain nutrients essential to plant growth.  Certain plants even thrive off of gray water.  Using gray water for irrigation will also reduce the total demand for fresh water, thus reducing the strain on the resevoirs.

This new contraption displays a possible means of reusing gray water.  The water used in the washing machine is diverted directly to the toilet.  This both eliminates the need for new water for the toilet and the need to treat the extra water.

Graywater (also spelled greywater, graywater, gray water)

The web's information central on all aspects of graywater
systems.

Gray water is all washwater from homes, excluding toilets.  Gray water can be resused for other purposes, lowering the demand for fresh water, energy, and chemicals.  Despite some legalities, the reuse of gray water is generally safe.  Reusing gray water offers many benefits, such as reducing strain on treatment plants, recharging ground water, and reclamation of otherwise wasted nutrients.

Some plants thrive on gray water, study says

Some plants thrive on gray water, study says | APES: Gray Water Uses and Technologies | Scoop.it

Many plants used for landscaping benefit from being watered with household gray water, according to a study released Monday by the nonprofit organization Water Environmental Research Foundation.

One may think that all the chemicals present in gray water cannot possibly be good for the environment.  It turns out otherwise.  Some plants actually thrive off of gray water.  The nutrients that the gray water contains will help plant growth, although it can be harmful for humans. If gray water is handled properly, it can be really successful with plant growth. Learn more.
