Well.. if your grass would dry out and become yellow without watering it, then watering is a luxury. The water in deep wells will eventually run out. Why waste it on grass?
All that said, I mean, if your HOA requires this, is the problem with the city charging for water use to upkeep the infrastructure required to deliver it? Or is the issue really just that your HOA has rules that it shouldn't?
And this is why I don't live somewhere where I'm ruled by an HOA
Or ripping up the lawn to plant something more sensible.
Or just not living somewhere where an HOA can tell me what to do with my own house
That's a different regulation issue. We shouldn't be overdrawing from those deep wells at almost any price, outside of extreme emergency.
