We all use RO water purifiers at our home to purify the drinking water, but do you know that around 75% of the water fed into RO water purifier is wasted, only 25% is extracted as drinking water. For 1 liter safe filtered drinking water in the RO tank, 3 liters goes rejected as hard water. This causes a tremendous Overhead on the Water Supply as well as Sewage Treatment system of Apartment Complexes.
Here is very simple solution for it, use it for washing clothes, kitchen utensils cleaning, floor moping, car washing, kitchen garden etc. Some people may say it is waste water how can we use it for anything.
Answer to that question is, Do you use purified water for anything else other than drinking? You don’t, right? You use untreated water directly for all other activities (other than drinking) and that water contains everything for which you are concerned while using RO waste water. So implement this idea at your home, apartment and save water, save money
