California’s urban water use jumped 8 percent in September compared with a year ago, the fourth-straight month that conservation totals have plunged after drought regulators loosened mandatory restrictions. September’s cumulative savings totaled 18.3 percent over 2013 levels, falling well below the state’s 23 percent average since regulators implemented mandatory drought laws in June 2015. The California State Water Resources Board said that while a majority of Californians remain stingy at the tap during the state’s historic drought, there’s room for major improvement.
