OPINION: San Diego Is Ready For Some Big Water Solutions

/in , /by /San Diego Union-Tribuneby Jim Madaffer

Back in the early 1990s — near the start of my career at San Diego City Hall — the San Diego County Water Authority launched a historic effort to sustain the region’s economy and quality of life by diversifying our water supplies so that we didn’t depend on one source for 95 percent of our water. That effort took many forms, many billions of dollars and more than two decades — but it paid off in spades. Even though we are at the literal end of the pipeline, today we have among the most diversified and secure water supply systems anywhere.

Cash Rebates Increase for Grass Removal in San Diego Region

/in , /by

Removing grass can generate rebates of at least $2 per square foot for San Diego residents under new enhanced incentives that started this month.

As of April 1, the Metropolitan Water District is offering $2 per square foot for every square foot of grass removed from yards and replaced with sustainable landscaping.

Rebates may vary by water agency, but an online incentive calculator identifies the current rebate amounts.

To increase participation, MWD also updated program rules. The rules are listed at the application site.

All San Diego County residents are eligible for the $2 rebate.

But, that’s not all. The San Diego County Water Authority is offering an additional $1.75 per square foot to customers in its service area, with grant funds provided by the California Department of Water Resources.  And, the City of San Diego offers city residents $1.25 per square foot. That means some homeowners can earn as much as a $5 rebate for each square foot of turf removed.

Turf rebate programs have proven popular in Southern California, and funds could go quickly.

Water Authority offers free landscaping classes

While rebates can provide a big boost to landscaping makeover projects, it’s also important to start planning before you start planting.

That’s where the Water Authority’s WaterSmart Landscape Makeover Program comes in. Free resources are available to upgrade turf yards.

For instance, the Water Authority offers free landscape makeover classes that help homeowners make smart choices to reduce outdoor water use by designing beautiful and climate-appropriate landscapes for our region.

“San Diego County homeowners and businesses know that sustainable landscapes are key to water reliability in our region,” said Joni German, who manages the Water Authority’s WaterSmart Landscape Makeover Program. With the help of local landscape architects and designers, our WaterSmart Landscape Makeover Program gives them the knowledge and skills they need to be successful. WaterSmart landscapes are an upgrade, not a compromise.”

Water Authority Seeks Statewide Solution to Drinking Water Woes

/in , /by

The San Diego County Water Authority’s Board of Directors on March 28 threw its support behind a coordinated statewide approach to ensure that all communities in California have daily access to safe, reliable drinking water.

The California State Water Resources Control Board has identified 329 water systems statewide that serve contaminated drinking water or cannot provide reliable water service due to unsound infrastructure or lack of resources. Most of the systems are in rural areas and serve fewer than 10,000 people.

More than a half-dozen bills have been introduced in Sacramento this legislative session to provide safe and reliable water supplies for disadvantaged communities in the Central and Salinas Valleys.

The Water Authority Board supports a plan to combine several measures into a unified legislative package.

“By amending several components of the relevant bills and linking them in a modified single reform package, we would advance a more comprehensive fix to drinking water quality issues throughout the state,” said Glenn Farrel, government relations manager for the Water Authority.

Safe Drinking Water Trust Fund

In addition, the Water Authority Board voted to support Senate Bills 414 and 669, both of which provide alternatives to water tax proposals in the Legislature that the agency helped defeat last year.

  • SB 414 would establish the Small System Water Authority Act of 2019 and authorize the creation of small system water authorities that could absorb, improve and competently operate public water systems that are chronically out of compliance with drinking water standards.
  • SB 669 would create the Safe Drinking Water Trust Fund to collect federal contributions, voluntary contributions, gifts, grants, bequests, transfers by the Legislature from the General Fund and the Greenhouse Gas Reduction Fund, funding from authorized general obligation bond acts, and other sources. Revenues would help community water systems in disadvantaged communities that chronically fail to meet federal and state drinking water standards and do not have the money to pay for operation and maintenance costs to comply with those standards.

The Water Authority Board voted to oppose SB 200, unless it is amended to address numerous concerns that are outlined in the staff report to the Water Authority’s Board.

A fourth legislative measure, an Administration Budget Trailer Bill: Environmental Justice – Safe and Affordable Drinking Water and Exide Cleanup, would impose a tax on water and agricultural activities to finance safe drinking water efforts. The Board voted to oppose the budget trailer bill unless it is amended, among other things, to remove water tax provisions and instead appropriate $1 billion in budget surplus funds to the Safe Drinking Water Trust Fund.

East County Advanced Water Purification Project on Track for 2025

/in , /by

The East County Advanced Water Purification Project is moving forward toward its anticipated completion date after the Padre Dam Municipal Water District’s Board of Directors approved the required environmental report.

“The approval of the environmental report for this project brings us another step closer to producing a local water supply for East County and improving the reliability of the water service for our community,” said Allen Carlisle, Padre Dam CEO/General Manager. “We are on track for the project to begin providing water to the East San Diego communities by 2025.”

The East County Advanced Water Purification Project is a collaborative partnership between the Padre Dam Municipal Water District, Helix Water District, County of San Diego and City of El Cajon. The partnership’s purpose is bringing a new, local, sustainable and drought-proof water supply to the East County, using state-of-the-art technology.

Advanced technology improves water reliability for East County

The project will recycle East San Diego County’s wastewater locally, and then purify the recycled water at an advanced water treatment facility using four advanced water purification steps. The purified water will then be pumped into Lake Jennings, treated again at the Helix Levy Treatment Plant and then distributed into the drinking water supply.

The water recycling project will help diversify East County’s drinking water supply, reducing the region’s dependence on imported water. It also helps the region in achieving long-term compliance with the Clean Water Act (CWA), the primary federal law in the U.S. helping to restore and maintain the integrity of the nation’s waters by addressing pollution and improving wastewater treatment. It is one of the United States’ first and most influential modern environmental laws.

Upon its completion, the East County Advanced Water Purification Project will produce up to 12,900 acre-feet per year, or 11.5 million gallons per day of new local drinking water supply.

“This project is forward-thinking, innovative and promises to give East County greater water independence and reliability,” said San Diego County Supervisor Dianne Jacob, who represents the East County region. “It will give us more local control over our most precious resource — and that’s great news for residents and businesses.”

Padre Dam offers tours of the East County Advanced Water Purification Demonstration Project. To schedule a tour or for more information on the East County Advanced Water Purification Program, visit www.EastCountyAWP.com.

High-Tech Tools Help Detect Possible Pipeline Problems

/in , /by

It’s a whole new ballgame for the San Diego County Water Authority when it comes to finding leaks in major pipelines with cutting-edge technology.

One new tech tool deployed for the first time in February actually looks like a tennis ball that floats through water-filled pipelines scanning for potential trouble.

Of course, the new device is much more complex inside than a tennis ball – in fact, the Nautilus is among the most advanced tools of its kind in the world.  It not only detects defects that are invisible to the human eye, it does so without requiring pipes to be drained, which saves a significant amount of water and disruption to customers.

Innovation Leader

The Nautilus is just the latest component of the Water Authority’s cutting-edge Asset Management Program that has been adopting and developing innovative tools for more than two decades. In fact, the Water Authority has been recognized by the American Water Works Association as a leader in the water industry for its focus on asset condition assessment, risk management, proactive pipeline replacement, and use of cutting-edge technology that saves ratepayers money.

“These high-tech tools are cost-effective and fit perfectly with our proactive approach to managing our infrastructure, including 310 miles of large diameter pipelines and 1,400 pipeline structures,” said Nathan Faber, an operations and maintenance manager with the Water Authority. “Our mission is to find potential failures in the system in advance, rather than react after a failure.”

‘Listening’ for leaks

The Nautilus uses acoustic feedback to detect leaks or abnormalities in active pipelines without causing any disruption to water service or supply, Faber said. About the size of a tennis ball, the Nautilus is placed inside a larger, sterilized foam ball, to float through operating pipelines.

For the First Aqueduct scan, 26 sensors, called synchronizers, were installed on various structures on the outside of the pipeline. Those sensors relayed information to the Nautilus as it floated between checkpoints. No leaks were discovered in the tested portions of the pipeline.

Leveraging new technology to gather data and pinpoint pipeline problems saves water and money.

“Responding or reacting after failures can cost up to six times the cost of proactive repairs,” Faber said.

He pointed to a recent pipeline repair project in La Mesa, where a Light Detection and Ranging device, or LIDAR, was used inside a pipe to provide highly-accurate digital measurements.

“The LIDAR took 1,600 measurements in five seconds,” Faber said. “The high-resolution images showed stressed pipe and verified cracking issues that allowed crews to make an efficient, proactive repair.”

Water Authority Adapts to Overheated U.S. Construction Costs

/in , /by

Construction costs have surged across the nation over the past year as prices for materials used in construction have risen. At the same time, contractors are struggling to meet project deadlines due to a shortage of skilled workers, construction trade industry publication Constructive Dive reported on March 18.

Those higher construction costs are impacting local agencies, including the San Diego County Water Authority. Agency staff briefed the Board of Directors’ Engineering and Operations Committee in mid-March on how those market changes are driving up costs of infrastructure and maintenance projects.

“The Water Authority will monitor market trends and adjust individual project budgets as required,” said Gary Bousquet, the Water Authority’s deputy director of engineering. “Our planning process includes prioritizing projects, and evaluating the timing or need and scope of projects. We will adjust our project cost estimates to meet changing market conditions.”

Labor shortage adds to increasing costs

A labor shortage in the construction industry is one of several factors increasing costs.

“While construction hiring remained very widespread through January [2019], industry employment gains nationally slowed in February—possibly an indication that the pool of qualified workers has dried up in many markets,” Ken Simonson, chief economist with the Associated General Contractors of America, said in a new report.

The report showed that construction employment declined by 1,300 jobs in the San Diego region from January 2018 to January 2019.

“There are many large-scale construction projects underway in Southern California, while at the same time, there is a shortage of skilled and unskilled labor, which means greater competition for those workers,” said Brent Fountain, a principal engineer with the Water Authority. “In addition, increasing prices for materials are impacting the costs for both maintenance and capital projects.”

Water Authority project bids from contractors in 2018 ranged from $200,000 to $6 million over the project costs estimated by the Water Authority, according to Fountain.

“We’ve received fewer bids at higher bid amounts from contractors for several projects in the past eight months,” he said. “The Water Authority generally had more bids and bid amounts closer to our project cost estimates, from 2014 through 2017.”

In previous years, bid amounts were typically closer to project cost estimates and sometimes the bids came in well below the estimates.

Bousquet said the agency will monitor construction industry cost trends as it continues pioneering projects to serve the region.

“The Water Authority has made an array of innovative infrastructure investments over the past 25 years, including some of the largest projects in the history of the agency, to sustain the $231 billion regional economy,” said Bousquet. “We will continue to develop cost-effective projects to provide a safe and reliable wholesale water supply to San Diego residents.”

Historic Pipeline Project Boosts Long-Term Water Reliability

/in , /by

San Diego County Water Authority crews successfully completed the first of three coordinated shutdowns of the First Aqueduct in early March to launch a major renovation of dozens of structures on two pipelines, including the historic Pipeline 1 that first delivered imported water to the region in 1947.

The series of shutdowns was carefully planned for nearly four years to minimize impacts on the community and retail water agencies during retrofits of Pipelines 1 and 2, which comprise the First Aqueduct.

“The First Aqueduct has been a very reliable source of imported water for more than 70 years,” said Chris Castaing, operations and maintenance manager at the Water Authority. “These critical upgrades will make sure we can operate and maintain the pipelines for another several decades to transport water to the region for future generations.”

Started during the Water Authority’s 75th anniversary year, the $30 million First Aqueduct structure and lining renovation project is among the most complicated pipeline retrofits in agency history.

During the next two years, upgrades include replacing the lining on the steel pipe sections; removing 19 associated structures; and retrofitting 41 structures – all without jeopardizing water service to the region.

Project will enhance reliability and flexibility of regional water system

Pipeline structures that will be rehabilitated include valves, blowoffs, pump wells and access ways.

Approximately 4 miles of failing pipeline lining on the steel pipe sections will be carefully removed and replaced with new cement mortar lining. Cement mortar is the preferred material, because it protects the interior of the steel pipe from corrosion and premature failure, has a longer life, and is easier to maintain. The project also will add redundant connections to six flow control facilities between the two pipelines, greatly improving the aqueduct’s operational flexibility.

During the first shutdown between February 24 and March 5, crews isolated sections of the pipeline and took them out of service so work can be safely performed on those sections throughout the year. In late 2019, a second 10-day shutdown will allow crews to switch flows to the upgraded sections of pipe and isolate other sections for repairs.

In addition to completing the First Aqueduct structure and lining renovation project, the Water Authority also will perform assessments of 27 miles of the pipeline to determine if additional upgrades will be needed.
