County Water Authority Votes to Support $17B ‘WaterFix’ Proposal

/in , /by /Fox 5 San Diego

The San Diego County Water Authority’s Board of Directors Thursday unanimously voted to support current plans for California WaterFix, the state’s $17 billion proposal to address water supply constraints in the Sacramento-San Joaquin Bay-Delta.

The board’s backing is contingent on a financing plan that fairly allocates project costs to San Diego County taxpayers, according to the Water Authority. The Metropolitan Water District of Southern California, the sole source of Bay-Delta water for the San Diego region, is responsible for such allocations.

Water Authority Conditionally Backs $17 Billion Delta Tunnels Plan

/in , /by /Times of San Diego Mentioned: San Diego County Water Authority

The San Diego County Water Authority’s board of directors gave conditional support Thursday to the California WaterFix, the state’s $17 billion plan to upgrade key water infrastructure.

San Diego joins the Metropolitan Water District in Los Angeles and Santa Clara County Water District in Silicon Valley in backing one Gov. Jerry Brown’s signature long-term projects.

The massive project would divert water from the Sacramento River as it enters the Sacramento-San Joaquin Delta and carry it to existing federal and state pumping stations in the southern part of the delta through one or two 35-mile tunnels.

When It Comes To Lawns, Use it or Lose It

/in , /by

If you have a desire and a need to retain turf as part of your landscaping, consider adopting the most efficient and organic maintenance plan possible. Lawns that are maintained organically and with efficient irrigation can offer a cool, practical surface for active recreation, or just hanging out with your family.  

Most lawns suffer from inefficient maintenance. They require too much water and energy. They become major sources of pollution from fertilizers and pesticide runoff. For these reasons, lawns should be limited to accessible, usable, high-functioning spaces like children’s play yards, sports fields, and picnicking areas. 

It’s smart to rethink the idea of lawns as all-purpose, wall-to-wall groundcover. In many cases, there is no need to maintain so much lawn. If you decide to keep your grass areas, follow these guidelines to maintain it organically.

  • Apply a thin layer of compost annually. 
  • Aerate and de-thatch your lawn annually. 
  • Manage your irrigation carefully. Control overspray and fix problems promptly. 
  • Mow less frequently. Maintain 3 to 4 inches of height on cool season grass, and 1.5 to 2 inches of height on warm season grass.  
  • Grass-cycle every time you mow. 
  • Don’t allow seed heads to form on the grass, and remove those that do form. 
  • Consider over-seeding with clover to help make the grass more interesting looking and more drought-tolerant. 
  • Eliminate chemical inputs to your grass. 

What’s the difference between Cool Season Grass and Warm Season Grass? 

Cool Season Grass: 

  • Needs more water than warm season grass and is considered a high use plant. 
  • Requires watering in hot summers to prevent it from going dormant and turning brown 
  • Grows typically as bunch grasses and propagates by seed or weak stolons. 
  • Cool season grass is easily smothered by sheet mulching.
  • Varieties include: Bent Grass (Agrostis), Fescue varieties (Festuca), Kentucky Bluegress (Poa pratensis), Perennial Ryegrass (Lolium perenne) 

Warm Season Grass: 

  • Is a moderate water use plant. 
  • Peaks when temperatures exceed 80 degrees, but it will go dormant (brown) in winter months when it is rainy and cool. 
  • Grows from sturdy rhizomes extending deep underground. Warm season grasses require physical removal and/or extensive sheet mulching (up to 12 inches).
  • Varieties inclue: Bermuda Grass (Cynodon dactylan), Blue Grama (Bouteloua gracilis), Buffalo Grass (Buchloe actyloides), St. Augustine Grass (Stenotaphrum secundatum), Zoysia, and Seashore Paspalum.

Efficiencies Lower Long-Term Water Demand Forecast for San Diego Region

/in , /by by Water News Network Staff

Updated water-use projections for the San Diego region through 2040 are substantially lower than earlier forecasts due to efficiencies that have become standard practice at homes and businesses countywide.

That’s good news because it signals the potential for lower spending on water supply development and delivery in coming decades compared to previous forecasts.

The revised demand forecast by the San Diego County Water Authority also highlights how the region continues to align with state mandates for water-use efficiency even after nearly three decades of significant savings. Per capita potable water use in the Water Authority’s service area declined nearly 50 percent between fiscal years 1990 and 2017.

Changing Water-Use Habits Prompt ‘Reset’

Revisions to the region’s water demand forecast were designed to align the Water Authority’s planning document with current water-use trends. Through the Urban Water Management Plan, the agency updates demand forecasts every five years, with the next comprehensive update in 2020.

However, emergency state regulations related to the 2012-2016 drought combined with the ongoing transformation of the landscaping market toward low-water-use designs and other factors significantly lowered water use between the formal five-year planning periods. That change prompted the interim demand “reset” by the region’s water wholesaler.

Instead of projecting 588,000 acre-feet of demand in 2020, the Water Authority now anticipates demand will be at 537,000 acre-feet – a reduction of approximately 9 percent. Projections through 2040 follow suit, so that annual demand is projected to be 655,000 acre-feet at the far end of the Water Authority’s planning horizon instead of 719,000 acre-feet.

“We wanted the forecast to reflect current conditions and demand levels, and we also wanted to have an inclusive process for receiving input from our member agencies,” said Tim Bombardier, principal water resources specialist for the Water Authority. “The net effect is that the interim demand forecast reset shifts the entire line down by about 60,000 acre-feet for the entire 2020 to 2040 planning horizon.”

The demand reset is intended as a provisional update, and a comprehensive update of the forecast will coincide with preparation of the Water Authority’s 2020 Urban Water Management Plan. Decreased demands change the amount of supplies necessary in future years, an issue the Water Authority will assess in detail when developing the 2020 plan. That process will start in late 2018.

State Sen. Hueso’s Interest in Water Runs Deep

/in , /by

San Diego County is a leader in water conservation and management strategies that will become even more critical in coming years, state Sen. Ben Hueso (San Diego) said during an Aug. 1 Legislative Roundtable at the San Diego County Water Authority’s headquarters.

“San Diego is really a model in the state,” Hueso told an audience of about 90 water agency representatives, business and civic leaders and other stakeholders from around the county who attended the morning event. “San Diego leads the state in conservation. How we’re able to manage the system without an increase in the growth of consumption is just amazing. It’s just a testament to the great minds and people that we have managing our system, ensuring that we continue to have water … given the enormous challenges we have in providing for San Diego compared to other parts of the state.”

The Water Authority regularly hosts roundtables to hear from elected officials about water issues and other important developments in Sacramento and Washington, D.C., and to promote collaboration with civic, business and elected leaders in ensuring continued water supply reliability for the region.

“We’re so pleased Senator Hueso could join us today because he plays such an important role in water issues and water plays such a critical role in our region,” said Mark Muir, chair of the Water Authority’s Board of Directors. “Senator Hueso has been a true champion in protecting important independent water supplies for San Diego and has always been willing to work closely with us to balance all the important interests related to those water supplies.”

Hueso has been a leader on water issues since he was elected to the state Senate in 2013. He  chairs the Senate Committee on Energy, Utilities and Communications, and he also sits on the Natural Resources and Water Committee. His 40th Senate District includes cities in south San Diego County, the southern portion of the City of San Diego, and all of Imperial County. A former San Diego City Councilmember, Hueso was elected to the state Assembly in 2010 and previously chaired the Assembly Water, Parks and Wildlife Committee.

Finding Common Ground

Hueso’s commitment to water started as a youngster delivering newspapers. “Every morning when I used to fold those papers I would see ‘Drought,’ ‘Drought,’ ‘Drought.’ ‘Water scarcity.’ ‘Water scarcity,” he said. “If you’re a native San Diegan, that’s something you hear about a lot.”

Drought or no, water remains an important topic in the nation’s largest state, creating a complex challenge for policymakers. “It gets complicated when you consider that our water policy in California started in 1848 before our state was even formed with the Treaty of (Guadalupe) Hidalgo – the treaty with Mexico,” Hueso said. “There was actual language in that treaty that was aimed at protecting property rights and water rights for the people that owned property back then. And those water rights still apply.”

While those complexities can create division, they also create opportunity for bipartisan solutions. “The most important things that we’ve done in the state of California have been bipartisan,” Hueso said. “And that has taken effort. It has taken effort on both sides to come to a common ground and say we’re going to agree to do what’s in the best interest of the state in general. And when there has been an urgent matter facing the people of California, both sides have come together to forge relations and form solutions that truly help everyone.”

How that will play out in the Sacramento-San Joaquin Bay Delta is still unclear, even as the state pursues a $17 billion project called California WaterFix that involves routing water underneath the Bay-Delta in twin tunnels.

A sense of urgency at the Salton Sea

Salton Sea restoration – a legislatively mandated responsibility of the State of California – is another priority for Hueso.

“My focus is set on how do we solve this problem, what’s the best vehicle, and how can we do it in a way that still takes care of the public funds,” he said. “We have to be mindful of how to spend this money because we don’t have a lot of it. We have to stretch every penny, stretch every dime, and there’s really little room for error. And that’s how I think we need to proceed.”

Then he added: “I really believe in creating an agency that is going to focus on solving this problem. We really need an agency that has a sense of urgency.”

Historic Water Deal Provides Less Expensive, More Reliable Supplies

/in , /by /San Diego County Water Authorityby Mark Muir, Board Chair

A historic achievement for the San Diego region passed almost unnoticed when the San Diego County Water Authority’s Board of Directors adopted new wholesale water rates in late June.

The rate-setting process highlighted how the Water Authority’s independent water supplies from the Colorado River are now both less expensive and more reliable than supplies from the Metropolitan Water District of Southern California. It’s an accomplishment that the region’s water officials started working toward two decades ago, and one that will bear fruit for decades to come.

The value of our independent water supplies will grow in coming years given the rapid increases in MWD’s rates, which have risen far faster than the cost of the Water Authority’s Colorado River supplies secured in 2003 through a complex, multi-state pact known as the Quantification Settlement Agreement.

Historic agreeement secures San Diego economy and quality of life

From the start, that landmark deal helped secure our economy and quality of life by giving us a major new source of water with a higher priority – or legal right – to Colorado River water than MWD. The agreement allowed the Water Authority to transfer increasingly large amounts of conserved water from the Imperial Valley to San Diego, so that by 2020 it will meet about half of our region’s projected water demand.

That visionary agreement also minimized the impact of MWD’s water delivery cutbacks during the past two droughts. In 2015, for example, MWD reduced water deliveries by 15 percent, but the Water Authority’s independent supplies meant we had enough water to meet 99 percent of normal demand.

While the supply benefits of the conservation-and-transfer agreement have long been clear, the region is just now starting to feel the cost benefits as well.

Here’s why: At the start, our independent Colorado River supplies were more expensive than MWD water. However, the cost of the Water Authority’s independent Colorado River supplies is controlled by a contract linked to the rate of inflation, which means those costs are rising far more slowly than MWD’s rates and charges.

Millions in savings achieved

In addition, the Water Authority has benefited from lawsuits that forced MWD to drop illegal charges for delivering our independent Colorado River supplies. A 2017 appellate court ruling netted the Water Authority about $15 million in savings in 2019, with tens of millions of additional savings in years to come.

The combined effect is that the Water Authority’s independent Colorado River supplies are less expensive than MWD supplies by $44 per acre-foot this year. In 2019, the difference will grow to $68 per acre-foot, and in 2020 our independent supplies are projected to be less expensive by $121 per acre-foot.

That’s worth celebrating because it means regional wholesale water rate increases in 2019 are among the lowest in 15 years – a testament to the all those who have worked for decades to secure a safe, reliable and cost-effective water supply for everyone who calls this place home.

USS Midway: A History of Sustainable Water Management

/in /by

The USS Midway Museum, docked in San Diego, is the most popular naval warship museum in the United States and among the most visited museums in the country, with 1.4 million people annually coming aboard.

Those visitors discover the Midway made its own fresh water while at sea, from the first day it was commissioned in 1945 until it was taken out of active service in 1992. But when this venerable aircraft carrier found new life as the USS Midway Museum in 2004, its relationship with water entered a new era as well.

The USS Midway Museum served as host for the launch of the San Diego County Water Authority’s new education and outreach program: Brought to You by Water.

The program underscores the importance of water reliability for the region’s key industries such as tourism and the military — something the operators of the USS Midway Museum understand on multiple levels.

Supporting a floating city at sea with water supplies

When deployed at sea, sailors aboard the USS Midway produced 240,000 gallons of fresh water daily through 12 boilers to support the floating city of 4,500 men. From cooking pasta to feeding sailors, to propelling the catapult system launching aircraft off the flight deck, the Midway depended on a safe and reliable water supply to thrive, just as the San Diego region does today.

Two evaporator plants deep inside the ship took in seawater and produced fresh water via desalination. According to Scott McGaugh, Midway Director of Marketing, working in those “evap spaces” was among the toughest duty assignments aboard the Midway. When one of these plants went out of service, the Midway had to ration its water.

Even in the best of times at sea, sailors always lived with a limited water supply, and water conservation was standard operating procedure. Consider a “Navy shower” — getting wet for 30 seconds or less, shutting the water off, soaping up, and then a quick rinse. That was the lifestyle during deployment, including a stretch when the Midway set a deployment record for aircraft carriers — 327 consecutive days at sea.

Water conservation remains a priority

Four steam throttle boards such as this were the gas pedals aboard Midway. Sailors here in 1958 fed the proper amount of steam into the four turbines necessary for propulsion and a top reported speed of 30 knots per hour. That’s 34 miles an hour for the 65,000-ton aircraft carrier when active—fast enough to water ski behind Midway. Photo: Courtesy USS Midway Museum

While the USS Midway Museum doesn’t have to generate its own fresh water anymore, the conservation mindset is still a part of its daily life. Chief Engineer Len Santiago for the Midway says it is a priority for his team of 64 engineers to be good stewards of water and the ship deploys modern technology such as waterless urinals and sensors on faucets.

The most critical issue for the USS Midway Museum is water leaks. The Water Authority encourages homeowners to monitor their plumbing for leaks. Now imagine monitoring hundreds of miles of pipes aboard a floating museum.

“My staff and I have to make sure first, no leaks,” said Santiago. His team checks all systems regularly. “We have hundreds of spaces where pipes run through. We check all sensors in our restrooms for guests are working properly. Problems like a running faucet are reported immediately.

“As we grow as a museum, our infrastructure will continue to grow,” said Santiago. “In the 21st century, we’ll continue to leverage technology. I expect to have sensors that will alert me to water on the deck somewhere that might indicate a leak – even in things like air conditioning.”

 

 

 

 

U-T Publishes Response to Errant Story on Water Issues

/in , /by by Water News Network Staff

The San Diego Union-Tribune on July 28 published and In Response article by Water Authority Board Chair Mark Muir that addressed a serious omission in a July 1 story about the cost of the regional water supply diversification strategy.

Said Muir: “Unfortunately, the story omitted clear-cut evidence that the region’s supply reliability strategy is an unqualified success: Our independent water supplies from the Colorado River are both less expensive and more reliable than supplies from the Metropolitan Water District of Southern California, which have been cut twice in the past decade by drought.”

Click here to read Muir’s published response. In addition, the paper has posted two corrections to the story.

However, the paper’s In Response format didn’t allow enough space to address other substantive problems in the July 1 story that the Water Authority had raised with the U-T.

For instance, the story inaccurately presented MWD’s water costs, which are actually about 30 percent higher than cited in the story because MWD adds substantial fixed charges on top of its volumetric charges, requiring additional calculations to arrive at a valid comparison with the cost of water from the Water Authority’s other sources.

“Clearly, Water Authority investments in more reliable supplies and large-scale infrastructure have contributed to higher local water rates, and we have never said otherwise,” said Muir in the article submitted to the U-T that was edited for space constraints. “However, no factor has had a bigger impact on wholesale treated water rates in our region since 2008 than rate increases imposed on us by MWD – a fact that would have helped readers understand the value of reducing reliance on MWD.”

The story also failed to serve readers by presenting Steve Erie as an objective, disinterested academic. In fact, Erie has been a paid consultant and expert witness for MWD in two major lawsuits against the Water Authority. Mr. Erie is entitled to his opinions and the U-T is entitled to print them – but the paper should have disclosed his business relationship with MWD, in which he was paid $250 an hour for his services.

Finally, it’s important to note that the story significantly undercounted the amount of water produced locally. In 2020, for example, the Water Authority expects the San Diego region will generate 39 percent of its supplies locally (not 30 percent, as the article said).

“Converted to gallons, that’s approximately the annual production of the drought-proof Claude ‘Bud’ Lewis Carlsbad Desalination Plant – a critical component of a successful, cost-effective strategy to support our region’s economy and quality of life,” Muir said.

2003: Colorado River Agreement Signed

/in , /by

In 1995, the San Diego County Water Authority began negotiations with the Imperial Irrigation District (IID) for the transfer of up to 500,000 acre-feet of water per year from the fertile farming area in the southeastern corner of California. In 1998, the Water Authority and IID signed an agreement that provided for the transfer of between 130,000 and 300,000 acre-feet of water per year, depending on the exercise of certain options. Despite legislation signed in 1998 by then Governor Pete Wilson to encourage the transfer, its actual implementation took five more years to materialize.

Faced with the propsect of reduced sales to its largest customer, the Metropolitan Water District (MWD) responded to the Water Authority-IID deal with an all-out battle to protect its monopoly. In late 2003, pressure from the California State Legislature and the governor forced MWD to back down. It joined the Water Authority, IID, the Coachella Valley Water District, state of California, and the U.S. Department of the Interior in signing the historic Colorado River Quantification Settlement Agreement (QSA). The QSA created a plan for limiting the state’s use of Colorado River water to its basic annual appointment of 4.4 million acre-feet, instead of continuing to rely on surplus supplies that belonged to other fast-growing states in the Southwest.
