A California town’s wastewater is helping it battle drought

Standing under a shady tree drooping with pomegranates late last year, Brad Simmons, a retired metal fabricator who has lived in Healdsburg, California, for 57 years, showed off his backyard orchard. Along with the apple, cherry, and peach trees, he’s packed one pear tree, two lemon trees, and a century-old olive tree into his bungalow’s compact garden. Of course, the small grove requires plenty of water — an increasingly scarce resource in a state that continues grappling with a historic drought despite recent torrential rains. Yet Simmons, like many of his fellow 12,000 residents, has managed to keep much of this wine country community north of San Francisco looking verdant while slashing the city’s water use in half since 2020.

California water: Metropolitan Water District offering rebates to residents looking to transform gardens to conserve water

As the state continues to deal with a historic drought, Southern California homeowners are getting the chance to transform their thirsty grass and gardens. The Metropolitan Water District offers rebates to residents ripping up their lawns and putting in plants that don’t need a lot of water to survive. Krista Guerrero, who works for MWD, took advantage of the offer and now has a native pollinator garden at her Rowland Heights home. It uses less water and will likely draw in more a more nature-friendly atmosphere. … She even had crews install a drip irrigation system. ”By changing out my irrigation system from a traditional spray-sprinkler to a drip irrigation system, I expect to see at least a 50 to 60 percent reduction in the amount of water that I use, and a reduction in my water bill anywhere from 30 to 70 percent,” she said. Guerrero said she paid around $8,000 for it all and will get $3,000 in return.
