This sign at a private home in West Austin means 'do not call the water police when you see see this property violating whatever stage of water restriction we are observing now.' We have various restrictions on watering that involve certain hours and days of the week and methods and they become more draconian the longer we go without rain. Last summer was horrible. But there is ground water and if you have the bucks you drill a private well. Then you post this sign or otherwise people call the hot line to report you watering on Tuesday or something.
