Urban Water Districts Consider Mandatory Conservation as Drought Deepens

/in , , /by /Politicoby Debra Khan

Urban water agencies are planning to impose mandatory conservation orders after federal water managers slashed deliveries this week amid a rapidly deepening drought.

The Bureau of Reclamation cut water deliveries from the Central Valley Project by about half. That has prompted the Santa Clara Valley Water District, which serves 2 million residents in the Silicon Valley region, to consider a potential conservation order at its board meeting next month. And the Contra Costa Water District, which serves 500,000 residents in the East Bay, is now planning to vote on one in July.

Water Authority Board Approves 2020 Urban Water Management Plan

/in , /by

The San Diego County Water Authority Board of Directors May 27 approved the Water Authority’s 2020 Urban Water Management Plan for timely submission to the state. The plan highlights how regional investments in a “water portfolio approach” to supply management and a sustained emphasis on water-use efficiency mean that San Diego County will continue to have reliable water supplies through the 2045 planning horizon – even during multiple dry years.

The Board approved the final plan following a public hearing on March 25 and a 60-day public comment period which ended May 6. The final 2020 UWMP will be submitted to the California Department of Water Resources by the July 1, 2021, deadline.

“Successful efforts to create a reliable water supply coupled with the development of new local sources by the Water Authority and its 24 member agencies ensure that the region will weather dry times over the next two decades,” said Water Authority Board Chair Gary Croucher. “We continue to collaborate with our member agencies on investments in infrastructure and local supply sources to benefit the region’s ratepayers now and in future years.”

Collaboration with member agencies

The Water Authority started the current UWMP process in September 2018, coordinating closely with its 24 member agencies, most of which must submit their own plans to the state. Member agencies provided input into the final plan as part of the Water Authority’s ongoing effort to align local and regional projections as closely as possible while still following applicable guidelines and using regional models. The plan’s long-range demand forecast shows an increase in regional demands of less than 1% per year through 2045. This change in demand is consistent with the change forecasted by other large water suppliers in the state, including the City of San Diego and the Metropolitan Water District of Southern California.

Multiple supply and demand projections factor into Urban Water Management Plans, which are mandated by the state to ensure sufficient supplies over 25 years. The plans are not used to set water rates; rates are set annually based on multiple financial factors at the time, not long-term projections about water supplies.

Water supply availability

Urban Water Management Plans are dictated by statutory guidelines, Water Authority Board direction and an agreement with the San Diego Association of Governments to use its regional growth forecast. The plans also support state laws that link approval for large housing developments to water supply availability.

By law, the plans must be updated every five years. Per state guidelines, the Water Authority’s Urban Water Management Plan includes:

  • Projected water demands under normal weather and dry weather scenarios
  • Conservation savings information
  • A process to conduct an annual water supply and demand assessment
  • Supply reliability analysis

The demand forecast accounts for changes in socio-economic factors, such as the number of projected housing units, the mix of single-family and multi-family dwellings, and employment growth.

Investments in local water supply

Conservation projections account for continued adoption of water-use efficiency measures, compliance with landscape water-use ordinances for new residential construction, and continued installations of sustainable landscapes at existing homes. Since 1991, San Diego County ratepayers have conserved more than 1 million acre-feet of water, and per capita potable water use in the region decreased nearly 50% between fiscal years 1990 and 2020.

The 2020 UWMP also highlights the value of the Water Authority’s long-term strategy to invest in highly reliable and locally controlled supplies from the Claude “Bud” Lewis Carlsbad Desalination Plant and the nation’s largest conservation-and-transfer agreement, which provides high-priority, low-cost water from the Colorado River.

In addition to the UWMP, the Water Authority also regularly updates its Regional Water Facilities Optimization and Master Plan, which focuses on the infrastructure necessary to meet projected long-term demands, and its Long-Range Financing Plan. Those documents work together to ensure the right mix of supplies and facilities to meet the region’s needs at an affordable cost.

Federal Government Slashes Water Deliveries to Farms, Cities as California Drought Worsens

/in , , /by /The Sacramento Beeby Dale Kasler

California’s water supply got cut again Wednesday, with the federal government reducing allocations to cities and farms as the drought intensified.

The U.S. Bureau of Reclamation announced that municipal water agencies that rely on the Central Valley Project will have this year’s allocations slashed from 55% down to 25% — a level not seen since the drought of 2015.

That could put additional pressure on the municipalities around greater Sacramento that depend on supplies from Folsom Lake, whose water levels have sunk dramatically this spring. The reservoir is at 46% of its usual capacity for late May.

Hoover Dam has helped store Colorado River water since 1935, but reservoir levels are nearing the lowest point since Lake Mead was filled.

Hoover Dam towers more than 700 feet above Black Canyon on the Arizona-Nevada state line, holding back the waters of the Colorado River. On top of the dam, where visitors peer down the graceful white arc of its face, one of its art deco-style towers is adorned with a work of art that memorializes the purposes of the dam.

California Water: Mandatory Restrictions Coming to Santa Clara County as Feds Cut Water Supply

/in , , /by /The Mercury Newsby Paul Rogers

In the latest and possibly most severe evidence yet of California’s worsening drought, the federal government on Wednesday announced it will cut water deliveries to urban areas it serves by more than half — and to zero for many farmers across the Central Valley.

The move will result in mandatory water restrictions across Santa Clara County, said Rick Callender, CEO of the Santa Clara Valley Water District, which provides water to 2 million people.

“We are truly in an emergency situation,” Callender said. “We’re going to be seeking everything we can do to address this emergency. The public should expect tighter restrictions.”

As Drought Worsens, Tensions Erupt Over Control of SoCal’s Largest Water Supplier

/in , , /by /Los Angeles Timesby Sammy Roth

Southern California’s biggest water supplier has chosen a new general manager — but the selection isn’t yet final, and the fiercely contested vote is exposing deep disagreements within the powerful agency as a severe drought grips the region.

The Metropolitan Water District’s board of directors voted this month to select Adel Hagekhalil to lead the agency, The Times has learned, replacing longtime head honcho Jeff Kightlinger, who is retiring. Hagekhalil runs L.A.’s Bureau of Street Services and was previously second-in-command at the city’s sanitation department.

Metropolitan finds itself at a crossroads after 15 years under Kightlinger’s leadership. The agency delivers huge amounts of water from the Colorado River and Northern California, and has prided itself on hammering out complex deals to protect the region’s water rights and investments. But those far-flung resources are becoming less dependable as the planet heats up.

Arizona’s Current Historic Drought May Be ‘Baseline for the Future’

/in , , /by /Cronkite Newsby Alyssa Marksz

Arizona and other Western states just lived through the driest year in more than a century, with no drought relief in sight in the near future, experts told a House panel Tuesday.

The period from last April to this March was the driest in the last 126 years for Arizona and other Western states, witnesses said. It caps a two-decade stretch that was the driest in more than 100 years that records have been kept – and one of the driest in the past 1,200 years based on paleohydrology evidence, one official said.

Valley Communities Lost Water in Last Drought. Are Small Water Systems Ready This Time?

/in , , /by /The Fresno Beeby Danielle Bergstrom

Arturo Rodriguez and his colleagues on the Poplar Community Services District board are responsible for keeping clean water flowing to 2,500 residents in the middle of a global pandemic and drought.

Of the community’s three wells, two are in production right now, although Rodriguez doesn’t know how long they’ll last through another drought. The other well is inactive because it is contaminated with nitrates. As the aquifer lowers this summer, even if the wells don’t run dry, they run a greater risk of becoming contaminated. Water suppliers are often forced to choose between a contaminated well or no running water.
