California is experiencing its fourth year of drought, with 2012-2015 being some of the driest years on record. The state water board has declared a drought emergency and issued mandates for water conservation across three categories: everyone, businesses, and water agencies. For everyone, outdoor water use is prohibited for activities like washing sidewalks and watering during/after rain. Businesses must only serve water upon request and hotels/motels must offer optional towel/linen washing. Water agencies are required to limit outdoor irrigation times and days, notify customers of leaks, and report on compliance.
