From The Rocky Mountain Collegian (Anna Mitchell):
I do not live in a country where safe drinking water is difficult to come by. Not only is my apartment’s water treated, but I have the means available to take my tap water and purify it further. We have so much clean water that it is used for things that purification is not even necessary for, such as flushing a toilet.
I am fortunate to have access to potable water on command. But that access could be unnecessarily excessive.
For water to be deemed potable, it must undergo an energy-consuming treatment to meet the Environmental Protection Agency’s standards of what is deemed safe to ingest, cook with, and bathe in. However, we use potable water for things like toilet flushing and irrigation despite there being no standards saying our toilet water must be safe to drink.
Greywater, or wastewater that consists of low levels of organic waste, is what drains from bathroom sinks, showers, and washing machines. While graywater is not deemed safe for drinking, there does not seem to be any problems for uses like plant irrigation. Greywater also does not require the same energy-consuming treatment that potable water necessitates.
Water conservationists, led by state Rep. Randy Fischer, have proposed a bill that will recognize graywater systems as a legal process in regions that decide to permit it as such. The bill was recently endorsed by the Colorado Water Congress. While I find water rights to be one of the most infuriating legal institutions in existence, I overall applaud these efforts in sustainability…
My support comes with a few conditions. The amount of effluent, or pollutant run-off, must be kept absolutely minimal. We cannot be initiating sustainability efforts for environmental conservation at the cost of harming the environment in other ways.
There should be absolutely no health concerns that result from having graywater around. The practicality and costs of initiating a system that separates greywater from potable water and black water (water containing large amounts of organic waste, such as from kitchen sinks and flushed toilets) should also be taken into consideration…
Perhaps a gray future is not such a bad thing, after all.
Graywater bill passes House Ag unanimously. Failed on a party-line vote last year. #coleg
