To me it is a very silly and wasteful practice to water one's lawn during a drought. Water is such a precious commodity and using it for aesthetic purposes of keeping a green lawn is a sin. So much in this world depends on water for survival. To sprinkle gallons of fresh water on a patch of parched grass sends of message of the lunacy society has come to in order to keep up appearances. Mother nature will take care of the grasses during a drought and will restore the lawn to its former beauty when the rains finally come.
