I’m not a native speaker. I just mean I use the city water supply when it’s not raining season, and when it starts raining (about half of the year here) I stop using (and paying for) it and use only rainwater. As I wrote in another comment here, my city has a lot of natural springs and I get water for drinking there.
There were a couple of years with extended drought season and the city’s water reserves got dangerously low and there was rationing. Since then, I got another five 260L barrels and tons of 5L bottles filled with rainwater under my stairs just for use on my lawn, garden, and houseplants. I don’t believe the climate is going to get any better in the future, nor that the population will get smaller or industry will use less water. Every year is hotter than the previous one. What I expect are longer and longer drought seasons, and I don’t think I’m prepared enough :P
