The water situation is much better this year than last - more reserves in the reservoirs.
Questions from householders generally are these.
Q.How much water do you use in a day?
Honest answer: About 100L or 20/25gallons a day - (I work say 16 days a month x 12 = 192 days a year @ 200L a day = 38400L divided by 365days in a year = 105L a day. The waste from the R/O I don't "use")

Q. Where do you get your water from?
I collect rainwater
By definition all water has been rain at some point(undergone the cycle of evaporation and precipitation), so technicaly that would be correct.
during the winter months in water butts. I've got a filter system
that "distills" it to a pure state.
