Now that the East Bay water district has imposed mandatory 19 percent cutbacks on water use, the San Francisco Chronicle's Carolyn Jones wandered around the suburbs, asking homeowners how or even whether they'll comply with the ruling. First up: a Danville contractor who says he's keeping the lawn and the pool. Good luck with that, Danville contractor! Maybe you can fight off the water cops with your nail gun. Batting second: Pleasant Hill mom, who promised to turn off her automatic lawn sprinkler. Attagirl, Pleasant Hill mom! You get our conscientious cul-de-sac consumer of the day award! If anyone wants to rat out their neighbors for gobbling down the dihydrogen monoxide, the tipline is 866-403-2683.
