With four straight days of rain, the Los Angeles River has come alive. Thanks to Measure W, which was passed by voters last November, projects will be funded and infrastructure will be built to capture, treat and recycle all this rain water. “We lose trillions of gallons of water out to the ocean every year, and if we were able to capture it, we could supply about half of our water needs locally,” said Jill Sourial with The Nature Conservancy.
