The availability of potable water is a key resource which is in very short supply now a days. This summer season we have heard about the crisis of water supply in many rural and urban areas of India (including various countries of world). The reasons are manifold and i am not indulging myself for the different causes. Today my post is towards the use of “Water Filters” for purifying drinking water. These purifiers are being used since a long time for various industrial, commercial and most importantly household purposes to save the cost of canned water & tanker supplies.
RO filters provides clean, healthy, better tasting water by removing bacterial contaminants, excess of solid particles and chlorine reducing the risk of gastrointestinal diseases, rectal cancer, colon cancer etc. By using this technology even briny water or brackish water can be made for the drinking purpose. but this technique is also magnifying the problem of water shortage.
The quantity of water wasted through purifier is the same as the amount it produces. Sometimes with the most inefficient RO the ratio becomes 4:1, means for producing 1 litre of potable water 4 litre of water is wasted. The wasted water could have been used for non drinking applications.
In most of the household i have seen that the waste water pipe giving out waste water is left in the kitchen sink. Here are few suggestions which can be followed or implemented by every individual actually could contribute towards their service towards the environment and their country.
1)Collect the waste water in buckets or cans and later can be used for mopping floors, cleaning bathrooms.
2) We can use the waste water to fill the “to be washed vessels” in sink. That’s what i do at my place.
3) We can use it for watering plants, gardening if the TDS-Total dissolved Solids is below 1000 (which we can ask RO maintenance guy to test).
4) For cleaning our vehicles.
5) For washing clothes.
On an average around 10 litre of water is wasted per person for making potable water for drinking, if every person started utilising the waste water as for the above given purposes we can save thousand litres of water per day. In my opinion its a very small effort which every single person can contribute.
We always don’t require big sacrifices to make the changes but a single effort by every individual can change the world.
If I change myself, I can change the world.
