Recycling Greywater

Greywater Recycling(1)

Have you ever thought about how to reduce your water bill? What is the best way to consume less water from the tap? Well, with a little bit of effort and a couple of good ideas, this is quite easy. Utilizing greywater is your answer and not only that your wallet will thank you for this, but you will also treat your environment better by spending less clean, drinkable water.

Greywater represents all kinds of water houses or office buildings produce, but which is not contaminated with fecal matter.All water which leaves a household is about 60% greywater.All water streams excluding the wastewater from toilets are considered greywater. These involve water from the sink, shower, bath, washing machines and dish washers and so on. Greywater is easier to treat than wastewater because it contains fewer pathogens. Therefore, it is easier to handle and reuse right onsite, for example, for toilet flushing and irrigation.

If wastewater contains toilet waste, as well, it is usually named black water. Black water is not safe for usage because it contains fecal matter. Many web sites give out information about greywater recycling methods and procedures and one of the leading authorities on this matter is Vladislav Davidzon, an expert in the area of permaculture.

Advantages of greywater recycling

There are numerous advantages from recycled greywater. Primarily, conventional water supply system will suffer much less pressure if we use greywater. Also, sewage systems are under less pressure. Reuse of greywater also means that less wastewater will enter watercourses through sewage systems. It lowers environmental endangerment risks. Finally, sustainable agriculture, among other things, revolves around recycled greywater.

Potential benefits from using greywater also include reduced freshwater consumption, reduced energy use, reduced chemical pollution, improved nutrient reclamation and better water quality (surface and ground water).Greywater

Common ways of greywater reuse

One of the easiest ways to make the best use of greywater is irrigation. Of course, some precautions are necessary. Whenever it is possible, greywater should be applied below the surface of the ground. If greywater is sprayed over the soil, there is a significant danger of inhaling the water in the form of aerosols. Of course, if greywater contains high levels of contaminants in the form of bleaches, dyes, bath salts, solvents, and acids or alkali, it should firstly be treated accordingly. Furthermore, since the soil can become high in pH, it should be treated with calcium sulfate.

Another good way to re-utilize greywater is toilet flushing. If greywater could be directed to toilets on a mass scale, water use could drop in 30% or more, for every household. Of course, some precautions need to be applied. These include control mechanisms which will control the flushing of water which has been stored for too long and cleaning tanks.

Finally, modern technology allows us to reclaim heat from greywater. It is a process most commonly called water heat recycling. These methods allow us to recycle the heat found in greywater which would otherwise go to waste.
