Water Conservation

Inside the Home
  • Wash only full loads of clothes and dishes
  • Never leave water running while brushing your teeth
  • Repair leaky fixtures such as faucets and toilets
Outside the Home
  • Water plants and yard only when necessary
  • Never water or use sprinklers during the heat of the day
  • If feasible, wash the vehicle on your lawn, not in the driveway where the runoff will be lost to the sewer
