San Diego Told to Cut Water Usage by 15%
Faced with a five-year drought approaching epic proportions, the San Diego County Water Authority announced Tuesday that beginning Feb. 1, it will call upon all county residents to reduce their water use by 15%--up from a 7.8% cut approved last month.
The announcement came on the heels of the Metropolitan Water District’s decision Tuesday to require Southern California water agencies to reduce their consumption by 17%--a step that officials said will force mandatory rationing throughout most of the region.
The decision came just five weeks after the giant water agency imposed a 10% conservation requirement on the 27 water agencies that serve 15 million customers from Ventura County to the Mexican border.
Local governments have the ultimate say over rationing plans, but Tuesday’s decision effectively limits the amount of water that cities and counties can expect from local water agencies. Officials said that MWD’s action will force many jurisdictions to adopt mandatory rationing to make up for the shortage.
“It’s always hard to generalize, but the decision to implement this stage (of conservation levels) makes it likely you’ll see mandatory rationing throughout Southern California,” said MWD General Manager Carl Boronkay.
San Diego officials, meanwhile, said that the stiffer rationing will present a challenge for the city, which is the county water authority’s largest consumer. San Diego is the only one among the county’s 24 member agencies to have thus far rejected mandatory conservation.
Milon Mills, the city water utilities director, acknowledged Tuesday that the MWD’s new guidelines will be difficult--especially since the city’s voluntary program, widely hailed as successful, averaged only a 10.7% savings over four months last summer.
“There’s no doubt that this is a challenge,” he said, “It’s going to take greater discipline. But the people have proven that they will respond, and I think they’ll do it again.”
Under the new conservation requirements, mandatory cutbacks in water usage will rise to 10% for residential consumers and 30% for agricultural users. Last month, already worried about the possibility of a fifth drought year, the MWD adopted cutbacks of 5% for residential users and 20% for farm irrigation.
San Diego County, which received 95% of its water from the MWD last year, requires equal cutbacks for residential and agricultural users, according to James R. Melton, a San Diego County Water Authority spokesman. Water officials said the stricter MWD measures would translate into a 15% cutback across the board for San Diegans.
For residential water users, the new cutback levels on residential users would require a typical family of four to conserve between 16,000 and 20,000 gallons of water a year, said Don Adams, director of resources for the MWD.
“That’s about the size of a residential-sized swimming pool,” Adams said.
The new conservation levels will go into effect Feb. 1 for all locales. The MWD had planned on a March 1 start-up date, but Metropolitan officials advanced the date after hearing a gloomy assessment of state water storage levels during a a briefing Monday by California Department of Water Resources officials.
High-ranking MWD officials said they were particularly concerned by reports that the Oroville and San Luis Reservoirs, which normally store 3.3 million acre-feet of water, now hold no more than 980,000 acre-feet of water. Even in 1977, the last drought year that forced mandatory rationing in Southern California, the two reservoirs held 2.2 million acre-feet of water. (An acre foot is 326,000 gallons, about what two average families use in a year).
“The reservoirs are essentially empty,” said Duane Georgeson, MWD assistant general manager.
Boronkay and other water experts said that in Los Angeles, which obtains water from other sources as well as the MWD, mandatory rationing now appears more of a certainty. City officials still cling to hopes of getting by on a voluntary conservation plan. But they acknowledge that without a last-minute blizzard in the eastern Sierra Nevada--a key city water source--rationing may well be inevitable.
“At this point, no one could accuse us of being imprudent in saying that mandatory rationing is becoming much more of a possibility,” said John Stodder, Mayor Tom Bradley’s environmental policy assistant.
Such a program could begin as early as March 1, Stodder said. City Department of Water of Power officials have been asked to brief the City Council on Feb. 1 about the state of the city’s water reserves.
“If the bad news we see now stays as bad as it’s been, there’ll be a discussion of mandatory rationing at that point,” Stodder said.
Normally, the city gets most of its water through the Los Angeles Aqueduct, which carries water here from the Owens Valley. This year, because of the drought and recent court rulings against the city, the flow from the Owens Valley is minimal. As a result, Los Angeles now relies on the MWD for about 60% of its water.
The MWD--which serves Los Angeles, Orange, San Diego, Riverside, San Bernardino and Ventura counties--gets most of its water from two sources--the State Water Project and the Colorado River. Neither supply will be as great as last year’s.
MWD officials said the cutbacks approved Tuesday are Phase III of a five-phase plan. Phase I, implemented last Dec. 1, was designed to achieve voluntary cutbacks of 10% for residential and industrial use. On Dec. 7, the MWD board voted to go to Phase II--mandatory cuts of 5% for residential and 20% for agriculture.
With worsening conditions, the cuts adopted Tuesday would rise to 15% residential and 40% agricultural in Phase IV, and 20% and 50% in Phase V.
Before the vote Tuesday, MWD resources director Adams warned that Phase IV looms as a “distinct possibility” if there is as little precipitation in January and February as there was in December.
Water authorities say that the 15% figure is about as high as residential users can easily conserve. Cutbacks beyond the 15% level would “start to really pinch,” Adams said, adding: “We hope we don’t have to go that far.”
Between April and September of last year, a voluntary program of water conservation reduced consumption in Los Angeles by about 11%. Conservation dipped to about 5.5% in October and about 7% in November.
If Los Angeles residents were required to conserve 10% under a mandatory program, “most people won’t feel a great hardship,” said Jerry Gewe, a senior engineer for water resources planning at the city’s Department of Water and Power.
“If you stop hosing down the drive, wash your car with a bucket instead of a hose, stop any leaks and use low-flow plumbing, that’ll probably do it,” Gewe said.
In Orange County, officials from about 30 agencies that supply water to local consumers said that mandatory rationing is unlikely in most of the county.
Water experts said that the county’s large supplies of reclaimed water and water stored in subterranean ground-water basins and reservoirs would enable many communities to stay with voluntary rationing programs.
“My impression is yes, voluntary will still be enough,” said Keith Coolidge, public affairs manager of the Municipal Water District of Orange County.
