From washing your car to watering the garden: Smart ways to use waste water generated by RO purifiers
Every year, the onset of monsoons leads to an increase in many water-borne diseases like diarrhoea and cholera. This is why it’s important to ensure you’re drinking clean water by either boiling it or using Reverse Osmosis (RO) water purifiers. While the purifiers come with many benefits, there is a certain amount of water that is wasted during the purification process. This occurs mainly due to its membrane technology that requires additional water to clean the filter, which is later discharged; the quantity expelled varies with the model of the unit. Due to the high content of total dissolved solids (TDS), this water is unsuitable for drinking, but you can put it to good use by taking some simple measures. However, it is best to determine the TDS level in the rejected water before doing so, because if it is too high, the waste water may not be suitable for reuse in most of the applications given below, as suggested by Vijay Babu, Vice President, Home Appliances, LG India.
Gujarat Government plans to reuse 100 million litres per day waste water

As per the policy the treated waste water will be used only for non-potable uses like construction activities, irrigation, maintenance of parks and gardens, rejuvenation of water bodies, among other uses.
