And I should have figured it out. Our sprinkler system was set before we bought the home, and I NEVER checked the timing! Derrick, from the water company, said that when a home is for sale, the sales person may jack up watering times to keep the lawn greener. As I posted in another thread, I am embarrassed about not finding the problem myself.

Anyway, ours was set to water two extra full cycles a week! 1900 gallon a time =16,000 gal a month!

Thanks to all, and especially VillageThinker-you are brilliant!
