We use a great deal of water just by going about our everyday lives. Bathing, doing the laundry, and washing dishes are all tasks that use a lot of water. The wastewater resulting from these activities is known as greywater and, while it is not potable, it can still be used for things like irrigation and flushing the toilet, etc. It is important to note, however, that greywater is a lot different from blackwater which should never be reused in an untreated state. Blackwater contains high levels of contaminants.
There are two categories when it comes to greywater, treated and untreated. When greywater is properly treated it can be stored for a period of time. Untreated greywater on the other hand must be reused immediately.
Opinions are often mixed regarding the use of greywater in homes. While some people view it as an excellent way to conserve our precious water, by using it for things like irrigation which uses a lot of water, others are concerned that greywater increases the risk of spreading disease-causing bacteria.
What should we take from these differing opinions? If you are wondering if greywater could be used in your home, do a lot of research into the matter and make sure you consult with your local council to see what regulations they have in place regarding greywater usage.
