Water Discovery Day at the Sacramento River Water Treatment Plant

Finally, the most terrifying Halloween-themed event of them all: learning about the city’s water treatment plant. Register and show up, then be greeted by the unholy knowledge of the methods the city uses to alchemize river water into drinking water, 100 million gallons every day. Your guide will fill you in on the plant’s workings—and you’ll even be able to taste water fresh off the line. 301 Water Street, cityofsacramento.org/Utilities/Water/Water-Discovery-Day.
