Now coming to the main crux of this post, the grey water recycling done with the help of this Canna plant can save you from water scarcity. This is what I have read about just few days back.
What is Grey water ?
Grey water is nothing but the waste water that is being produced from baths, sinks and washing machines. This grey water completely differs from black-water which is a sewage. Hence grey water is safe to use and recycle.
Grey water recycling (GWR) :
Grey water recycling (GWR) is done in many ways. The recycled water is used widely used for irrigation purposes , indoor reuse and in critical situations. The vital point to be noted is not all kind of purification methods is potable. Some of the recycling methods were done without purification and some were done with purification.
The grey water recycling process that I have read in 'The Hindu' Newspaper just few days back comes under the recycling method with purification that is done in the biological way which includes this Canna plant as a main source for purification.
Here's the link from 'The Hindu' newspaper where I read about this process :

If you go through that entire article, you can understand how much benefits we would get through this process. It is mentioned that this GWR process was already mentioned along with the rain water harvesting system that was implemented in the year 2002. But very few are aware about this till date. Today, almost many cities including Chennai are in quest for uninterrupted water supply especially during the summer. An apartment in Adyar, Chennai is said to be free from this quest as they have implemented this process with the help of the Canna lily plant.
I hope that this process would be a solution for water scarcity, pollution free environment and for an adequate ground water source.
