Water Usage Rate Remains Relatively Stable
Given San Bernardino County’s arid climate, effective water management is essential to ensure that the county has an ample water supply now and in the future. Statewide mandatory urban water restrictions, which went into effect in July 2014 and were lifted in November 2017, imposed water usage limits and prompted increased conservation and recycling. This indicator measures estimated residential water consumption in gallons per capita per day from larger water suppliers serving San Bernardino County.1 It also shows the percentage of water saved since the baseline year of 2013. The water suppliers providing usage data serve an estimated population of just over 1,700,000 (or roughly 78% of the San Bernardino County population).2
