Water is a commodity that most of us take for granted. What’s troubling though is that the consumption of water is much more than its rate of renewal. Using water carefully is a part of the solution to this problem. But what about partially-waste water, like water from sinks, laundry and general sewerage that does not contain fecal matter? This water cannot be filtered to be drinkable again, but it can be reused for a lot of other important purposes. This kind of water is called graywater.
Graywater usually goes to water-treatment plants where it is treated to be used again in sinks and laundry systems. What’s even better is that it can also be used for irrigation purposes. Graywater usually contains fewer levels of pathogens than home sewage from toilets, and thus is easier to treat. In fact, home owners can setup their own graywater treatment systems so that the burden on urban water systems can be lessened. The applications for this ‘recycled’ greywater are numerous, the most obvious ones being for flushing toilets and general irrigation.
There’s one catch to treating graywater at your own place – it has to be used within a short span of time or else it quickly putrefy due to its recycled nature. It is never advised to use this treated graywater for drinking purposes. If you intend to use the recycled graywater for irrigation purposes, it is generally advisable that the graywater should not be very chemical-heavy. What that means is that the detergents being drained with the graywater should generally be non-toxic.
