Water-wise tip: Use a broom

This seems so old-school, but using a broom to sweep down your driveway and sidewalks saves a lot of water. How much? One study from the Metropolitan Water District in Southern California estimated that sweeping instead of washing down pavement saves on average 150 gallons every time you clean. If you sweep once a week, that’s 7,800 saved gallons a year.
