Urban Water Supplier Conservation Tiers (Excel)
This spreadsheet lists the conservation standard assigned to each urban water supplier (suppliers serving more than 3,000 connections) as part of the Water Board’s emergency regulation to address specific provisions in Governor Brown’s April 1, 2015 Executive Order, which included a mandatory 25 percent statewide reduction in potable urban water use between June 2015 and February 2016. More information is available in the fact sheets about implementing the emergency regulation and assessing compliance with the conservation standards.
