DWP orders two-day-a-week watering restrictions citywide

Nearly 4 million Angelenos will be reduced to two-day-a-week watering restrictions on June 1 under drought rules released by the Los Angeles Department of Water and Power on Tuesday.

The highly anticipated announcement came two weeks after the Metropolitan Water District of Southern California called for the strictest-ever water cuts in the region due to worsening drought conditions and reduced supplies from the California State Water Project. The MWD action left many to wonder just how the rules would be applied in LA

Unlike some water agencies affected by the district’s order for a 35% reduction, the DWP opted not to scale back to one-day-a-week watering rules. Instead, it will focus on staying at or below a monthly volumetric allocation, top officials said.

“We’ve elected to use the allotment number because we do still have our own aqueduct supplies, our own groundwater, and we have the ability to shift some of our demands on to the Colorado River where there’s not a restriction,” said Martin Adams , the DWP’s general manager and chief engineer. “We believe that going to two-day-a-week watering and getting people to really pay attention and ramp down their water use will keep us within the allotment that Met has offered us.”

The new Phase 3 rules will apply to everyone in the DWP’s coverage area — not just those that are dependent on State Water Project supplies, Adams said.

Under the rules, residents will be assigned two watering days a week based on even- and odd-numbered addresses, with watering capped at only eight minutes. Those who don’t comply will receive a warning, followed by escalating ends for each subsequent violation, he said.

The outdoor watering plan released Tuesday is less restrictive than those of other nearby agencies — including Three Valleys Municipal Water District’s, which will move some areas to Phase 5 of its ordinance. Mayor Eric Garcetti told The Times that this was because Angelenos have already made progress conserving water. For example, DWP customers have been in Phase 2, which includes three-day-a-week watering rules, since 2009.

“If you just fixate on the watering days a week, it feels like less, but if you look comprehensively, DWP has consistently, is and will do more than most of those agencies collectively in all sorts of different places,” Garcetti said, noting that the city has also invested heavily in rebate programs for turf replacement and appliance upgrades to improve residents’ water efficiency.

The mayor also said he hopes to get away from the notion of “feast and famine” when it comes to water in LA

“I’m not going to ever back away from the urgency and focus, but I don’t think that means [we need] the stress and the nihilism of ‘LA can’t do this,’” he said. “We absolutely can, we should and we must.”

Garcetti’s message was more optimistic than the one delivered by MWD officials only weeks ago, when General Manager Adel Hagekhalil said that “we are seeing conditions unlike anything we have seen before,” and urged serious reductions in water use. He and other water officials said the cuts were necessary because the driest January, February and March on record had left California with meager snowpack and depleted reservoirs.

Hagekhalil said the goal was to reduce water use among State Water Project-dependent areas from about 125 gallons per person per day — including in residential, commercial and industrial sectors — to 80 gallons in order to avoid stricter cuts. If conditions don’t improve, he said, a full outdoor watering ban could come as soon as September.

DWP officials said their customers are already averaging about 112 gallons per person per day, less than half of that of some other nearby agencies. The combination of two-day-a-week watering across the entire service area, enhanced conservation efforts and other local supplies means they can cap residents at about 105 gallons per person per day and still stay within the MWD’s allotment.

“That number would be I think very successful in getting us through this drought,” Adams said.

The move to Phase 3 also triggers other measures, including a call for residents to use pool covers to decrease water loss from evaporation. Exceptions for drip irrigation and hand watering will remain in place.

The DWP will also ramp up patrols to look for people violating rules or wasting water. However, Adams said, the plan is less about punishment and more about proactivity.

“You tell people how much water they use in a day and they’re shocked,” he said. “People generally have no concept of that, but once they know, people pay attention…. What it takes is continual messaging to customers to get people to realize that this is important, they need to make these changes, and those will result in real savings.”

Anselmo Collins, senior assistant general manager of the water system for the DWP, said the city is also looking ahead toward longer-term solutions, including encouraging the MWD to build a conveyance system that would allow the entire DWP service area to gain access to regional storage supplies.

Other long-term plans include enhanced capabilities for groundwater remediation, stormwater capture and water recycling, Collins said. One major initiative, Operation Next, aims to recycle as much as 100% of purified wastewater from the Hyperion Water Reclamation Plant by 2035.

The agency is also replacing aged infrastructure and has set a goal of replacing about 200,000 linear feet of pipe each year, he said. Though several major water main breaks during a previous drought were attributed to shifting watering rules in Los Angeles, Collins said that wasn’t the case, and the DWP’s water loss remains “one of the lowest in the entire country.”

The restrictions will now move to the City Council for final approval, officials said. Collins said he believed Angelenos could achieve the needed savings under the new rules.

“We use as much water today as we did 50 years ago with over a million people more in the city, and that’s because of conservation,” he said. “We believe that all the efforts that Angelenos have made throughout all these decades is the reason we can go to this phase — two days a week — and be able to meet the challenge.”
