I am writing to express my concern about the significant wastage of water by the RO (Reverse Osmosis) water purification systems. These systems typically waste 3-4 liters of water for every liter of purified water produced. This is a substantial loss, especially in regions where water scarcity is a pressing issue.

I believe it is important for us to explore more efficient water purification methods or find ways to utilize the waste water effectively. Simple measures such as using the waste water for gardening or cleaning can help mitigate the wastage to some extent.in my family we always save this waste water and use it in cleaning or watering plants
