In July, Gov. Gavin Newsom asked Californians to reduce residential water usage by 15% to help combat the drought. Back in 2015, then-Gov. Jerry Brown asked for a 25% reduction. A year later, residential water usage was down 24.5%. But now, some Californians who made those impactful changes half a decade ago — ripping out lawns, replacing old toilets and showerheads, letting the Prius develop a tactile layer of dirt and dust before hitting the car wash — are stumped as to how to cut back any more without risking a body odor apocalypse on top of the climate one.
