A study by the Public Policy Institute of California in 2019 found that per capita urban water use in the state has dropped consistently over the years, from 231 gallons per day in 1990 to 180 gallons per day in 2010, then dropping to 146 gallons per day during the drought in 2015. This clearly bodes well for addressing the next drought, which could be on the way, but doesn’t address the challenges posed by suburban households with yards, which tend to use far more water than average.
In 2014, as Californians coped with the last severe drought, the Pacific Institute compiled data from the water districts serving urban consumers across the state in order to report per capita water use by region. The findings indicated that suburban households in the drier parts of the state were consuming water a per capita rate nearly three times the average; well over an acre foot per year per household.
Confronting this challenge addresses one of the key arguments of the anti-suburb movement: If every one of California’s 13 million households consumed an acre foot of water per year, residential water consumption in the state would be 13 million acre feet per year instead of the current 5 million acre feet per year.
There are many answers to this challenge, but exploring these answers, and the attendant policy solutions, should not merely rest on draconian restrictions on water use combined with a war on new suburban development. The other […] Read More
