During a two-year drought, reservoirs supplying Westbay dropped to record lows, and officials needed to cut water use quickly. The city launched two efforts at the same time: Westbay Leak Hunt Sensors and Westbay Recycled Water Lines. Westbay Leak Hunt Sensors used sensors to detect leaks in aging water pipes, and early checks suggested it stopped thousands of gallons from being lost each day. Westbay Recycled Water Lines expanded pipes that delivered treated recycled water to parks; planners predicted it reduced the need for drinking-quality water outdoors. Budget notes showed that the two efforts required different kinds of support. Westbay Leak Hunt Sensors required crews to dig up streets for repairs, while Westbay Recycled Water Lines required expensive infrastructure changes. Officials said the comparison mattered because a strategy that works fast is not always the one that lasts longest.
