I have two 10,000 liter water tanks in my basement that I use to harvest rainwater, and another 2,000 liter tank on my roof. From October to around May I close the city water and use only rainwater. I’ve been doing that for a bit more than 10 years now, and it paid for the installation cost in about 4 or 5 years. I also have solar water heaters, but it’s hard to tell how long they took to pay for themselves because I also have on-grid photovoltaic panels for energy generation. My energy bill is about 1/6 of my neighbors’, and the photovoltaic panels paid for themselves in about 5 years as well.
When you say "I close city water', sounds like you are also drinking that water? Sounds like a cool idea that I too have been thinking about. That water needs disinfection though
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.
