The San Jose Mercury News reports: Despite having the second-highest per capita consumption in the Bay Area, the Bear Gulch District serviced by the California Water Service Co. has cut water use only 11.3 percent since 2013. The district includes Woodside, Portola Valley, Atherton and portions of Menlo Park and Redwood City.

In the Alameda County Water District, water use plummeted 20.5 percent compared with 2013.

“We can turn off their water if we need to,” said Stephanie Nevins, the Alameda district’s water conservation supervisor. “But we haven’t had to. We’re delighted about how responsive customers have been.”

A National Science Foundation-funded research study by UCLA scientists confirms the Bay Area pattern. Analyzing 10 years of data that linked water consumption with socioeconomic demographics, prices and other factors, the study concluded:

• Income is the primary driver of water consumption. Wealthier neighborhoods consume three times the amount of water that less affluent neighborhoods use.
• Single-family residential households overwater their grass, flowers and shrubs.
• “Tier pricing,” which sharply increases the cost of water as usage goes up, encourages conservation.

The greatest reduction of water use results from a combination of mandatory restrictions and price increases, supported by incentives and outreach, according to the UCLA study.

Woodside is filled with large estates owned by Silicon Valley luminaries that have included, in addition to Ellison, venture capitalist John Doerr, Intuit founder Scott Cook, investor Charles R. Schwab and Internet entrepreneur Jeffrey Skoll.

Landscape irrigation accounts for 70 percent of the district’s water usage, internal data show. The state average is about 50 percent.

Menlo Country Club in the Bear Gulch District, which uses potable water on its fairways, says it is seeking a recycled water source.

About 300 Woodside households use more than 75,548 gallons a month, according to Cal Water. Many of those residents use more than a million gallons of water a year — for just one home. [Continue reading…]

The Los Angeles Times reports: Water usage in Los Angeles was 70 gallons per capita. But within the city, a recent UCLA study examining a decade of Department of Water and Power data showed that on average, wealthier neighborhoods consume three times more water than less-affluent ones.

With Gov. Jerry Brown’s order requiring a 25% cut in water consumption, upscale communities are scrambling to develop stricter laws that will work where years of voluntary standards have not. Many believe it’s going to take a change in culture as well as city rules to hit the goal.

“Some people — believe it or not — don’t know we are in a drought,” said George Murdoch, general manager of utilities in Newport Beach, which is beginning to fine chronic water wasters. “We have people that own a home here but aren’t around a lot, so they could miss a leak.”

Stephanie Pincetl, who worked on the UCLA water-use study, said wealthy Californians are “lacking a sense that we are all in this together.”

“The problem lies, in part, in the social isolation of the rich, the moral isolation of the rich,” Pincetl said. [Continue reading…]
