Water Crisis

At a time when major cities across India like Bangalore and Delhi are experiencing a major water crisis, critical interventions are the need of the hour. For what could work one should look at fellow nation South Africa for their handling the Day Zero crisis. The day when there is no more portable water available for use by the citizen. Here's some related coverage "Day Zero: Where Next?" (https://www.nationalgeographic.com/science/article/partner-content-south-africa-danger-of-running-out-of-water) & "Bengaluru is dying of thirst because it’s drinking its own Kool-Aid" (https://the-ken.com/the-nutgraf/bengaluru-is-dying-of-thirst-because-its-drinking-its-own-kool-aid/).

Reverse Osmosis (RO) water purifiers are both a boon & bane for the average household. Whith supply water TDS remaining way way above the palatable levels, ordinary non-RO basic filteration machines are rendered useless. But then RO machines end up throwing away waste water to the levels of about 5 - 10 litres (depending upon various factors) for every litre of drinking water purified. A criminal waste of the precious resource!

Now we've been recycling the RO Waste water for other household cleaning, watering, etc purposes. This process might take you back in time to the days of filling up buckets of water from the supply line (a reality for many to this day), well, etc for use. Though a bit cumbersome this recycling bit works. In a span of one day we may be able to collect about 2 - 3 buckets (30 - 40 litres) of water which would otherwise have gone down the drain. All said and done, it's well worth the effort!
