Otay Water District Instagram Contest Winners Get Social About Water

/in , /by

The Otay Water District named eight winners of its first Instagram photo contests, asking customers to depict two distinct themes.

In the first contest, four Otay Water District customers were selected winners of the agency’s first Instagram photo contest, “Thankful for Water.” During the 2019 holiday season, Instagrammers were invited to submit photos reflecting their appreciation for water.

“It might be formula, but it’s also tap water! Keeping baby healthy!” wrote first place winner Alisha Woodman. Instagram photo contest

“It might be formula, but it’s also tap water! Keeping baby healthy!” wrote Alisha Woodman, who won for the most “likes.”

One photo captured the use of water preparing for a holiday meal. Many people submitted wildlife and landscape photos. And, of course, there were selfies. Though the entry image choices varied, all depicted a precious resource — water — needed during the holiday season and year-round.

The second contest in December asked participants to submit photos with the theme “Drink Tap December.”  The focus was the importance of drinking safe and reliable tap water. Entries included a photo of the ocean beneath a pier, representing how tap water helps keep the ocean plastic-free; a toddler enjoying a bottle of milk made with water from the tap; and a photo from a demonstration in Tanzania on the difference between clean and unclean water.

“A moment that truly touched my heart. Seeing the difference between clean and unclean tap water, making a clay pot that will filter tap water and getting to meet the Masai family who will benefit from my gift that prevents typhoid and water borne diseases. We are fortunate to live in a country that has clean water. Only half of Tanzania’s 22 million people have access to clean drinking water,” said winner Margaret Meyer of Chula Vista.

Lake Jennings Hosts Kids Fishing Day

/in , /by

Hundreds of pounds of rainbow trout were biting for participants on Saturday during the sixth annual Kids Fishing Day at Lake Jennings in Lakeside.

The event started in 2015 has been an annual highlight ever since its inception. Kids ages 9 and under fished for free all day Saturday at the Kids Pond, which is a 20-by 20-foot cube within the lake.

Recreation Manager Kira Haley says Lake Jennings was stocked with 2,000 pounds rainbow trout from Wright’s Rainbows in Thatcher, Idaho the week of February 3. Eight hundred pounds went directly into the Kids Pond, which is then attached to the floating accessible fishing dock.

“Kids don’t remember their best day in front of the television, but they remember the first day they caught a fish with a proud parent cheering them on,” said Haley.

Two hundred kids got to catch and take home a trout. Haley says kids as young as two years old participated with a little adult help, including volunteers from the Lakeside Optimist Club, who helped prepare the fishing rods for the kids. Bait choices included nightcrawlers, cheese, white power worms, and mealworms.

Operated by the Helix Water District, Lake Jennings stocks 20,000 pounds of trout annually on a biweekly schedule between November and April when water temperatures are cool enough for trout to survive and 10,000 pounds of catfish in the warmer summer months.

In addition, large-mouth bass, red-ear sunfish and bluegill, as well as channel and blue catfish live in Lake Jennings. Sign up for the Lake Jennings Fish Report online to see what fish are biting.

Recreational fishing is the second most popular leisure activity in the U.S., second only to running. While the majority of avid fishermen and women are over 45, approximately 11.25 million youth ages six to 17 participate in fishing in the U.S. annually

‘Baking Skills’ Used for Repair at Lake Hodges Pumped Storage Facility

/in , /by

You might not think ‘baking skills’ would come in handy to fix a recent problem at the Lake Hodges Hydroelectric and Pump Station Facility. But those skills, along with initiative and ingenuity, were demonstrated by San Diego County Water Authority staff as part of the creative and complex repair.

The facility connects the City of San Diego’s Hodges Reservoir with the Water Authority’s Olivenhain Reservoir. The connection provides the ability to store up to 20,000 acre-feet of water at Hodges for emergency use.

The Lake Hodges Hydroelectric and Pump Station Facility moves water between Olivenhain and Hodges, and is able to generate up to 40 megawatts of energy on demand, helping to manage electrical demands throughout the County. It also generates revenue and helps offset energy costs.

Ground fault alarm alerts staff

A ground fault alarm on August 25, 2019 alerted staff to a potential problem with Unit 2, one of the facility’s two 20-MW pump-turbine units. A series of tests and inspections by staff with the Water Authority’s Rotating Equipment team discovered the insulation on the copper bus bars of the generator’s rotor were worn and damaged. The bus bars are part of a system that provides DC power to the 12 electromagnets which surround the outer surface of the pump turbine unit’s rotor.

The rotors are designed to spin at 600 revolutions per minute and it’s the rotor’s electromagnets acting upon the stators windings that generates power. The electromagnets are connected together by copper bus bars located on top of the rotor and the bus bars are secured to the rotor by clamping plates and rim studs. The bus bars are insulated to ensure the copper does not touch any other metal surface and cause an inadvertent ground fault.

“Although a single ground fault may not damage the pump-turbine unit, it may prevent it from starting, if two ground faults were to occur, significant damage to the pump-turbine unit would occur and would also be an extreme danger to anyone within the facility,” said Jim Fisher, Water Authority director of operations and maintenance.

Creative solutions and ingenuity save time, money

Among various factors, the primary cause of the insulation failure was determined to be improper wrapping and curing of the insulation during initial installation.

Water Authority staff developed solutions and also took on the repair tasks in September. By doing the work in-house, the Water Authority avoided a more extensive outage due to long lead times required by contractors and vendors to perform the same work, saving time and money.

“Staff did an excellent job maintaining the operation of Unit 1 while making the repairs to Unit 2,” said Fisher, “which allowed the Water Authority to avoid a total shutdown and loss of all revenue during this period.”

‘Baking skills’ come in handy to create new bus bars

New copper bus bars were fabricated, and each had to be precisely wrapped by 5 different types of insulating tape materials. This wrapping process alone took approximately 8 hours per bus bar. The bus bars were then baked for ten hours within newly designed and fabricated aluminum molds to ensure proper pressure was applied to the insulation layers during the baking and curing process.

Staff efficiently re-purposed and utilized an oven that had been retained from the San Vicente Dam Raise Project to perform the baking. The Rotating Equipment team’s efforts produced excellent quality results which would have been difficult even for a vendor to meet. The newly insulated bus bars were re-installed, and the unit has been operating safely and without issues.

“The initiative, ingenuity, and highly technical skills and knowledge of our staff were once again on display throughout the repairs,” said Fisher. “Their dedication, talents and outstanding efforts continue to ensure the Facility’s efficient and safe operation.”

Unit #2 was tested and placed back into service on November 17, 2019.

Along with the bus bar insulation and curing process repair, staff also performed many other highly technical, innovative and precise processes to complete this repair work.

Imperial Valley Conservation Efforts Benefit San Diego, Southwest

/in , /by

The San Diego County Water Authority’s Board of Directors visited the Imperial Valley January 30 for a day-long tour that highlighted areas critical to the agency’s Regional Conveyance System Study.

Board members approved a study in July 2019, to evaluate a new regional water conveyance system that would deliver water from the Colorado River to San Diego County and provide multiple benefits across the Southwest.  The Board will hear results from the first phase of the study this spring before deciding whether to move ahead with Phase B.

Imperial Valley tour of potential routes for regional conveyance

The tour started in southwestern Imperial County, where the All-American Canal meets the Westside Main Canal, an historic location where, starting in 1919, water from a canal system in Mexico first flowed into the western half of the Imperial Valley. It is also the place where three potential routes for a new water conveyance system, now being analyzed in the study, would begin.

“The goal of the study is to determine first, whether there is a cost benefit to the Water Authority and its member agencies in the long-term to build a regional conveyance system to transport our independent Colorado River supplies from the Imperial Valley directly to San Diego County,” said Dan Denham, the Water Authority’s deputy general manager.

One specific benefit to the Water Authority, the Imperial Irrigation District, and farmers in the Imperial Valley, would be the proposal to build an operational storage facility in the valley’s western area. The facility could help manage water deliveries to serve the needs of agriculture in the valley, while helping the Water Authority manage its transfer supply.

The trip included visits to several agriculture fields for a first-hand look at the latest conservation techniques used by farmers under the 2003 Colorado River Quantification Settlement Agreement.

Tom Brundy: Conservation is ‘extremely important’

Tom Brundy has been farming in the Imperial Valley for more than 40 years, and today he grows hay on 4,000 acres. Most of the hay produced by the farm is sold to customers in San Diego County, one of many connections between Imperial and San Diego counties.

“Every farmer in Imperial County is conserving water, and quite a bit,” said Tom Brundy, president of the Imperial County Farm Bureau. “I have subsurface drip on alfalfa, we’re using soil monitors and soil sensors to help us in our water scheduling, and we continue to modify our methods using new technology that saves water.”

Farmer Alex Jack: ‘out of the box thinking’

Jack Bros. Inc. also is an innovator in on-farm conservation. Alex Jack is a third-generation farmer using pump back systems and permanent drip irrigation. Many of his crops, from lettuce to cauliflower, are grown with zero water runoff.

Jack calls his progressive approach “out of the box thinking.”

“My goal is to be the best farmer possible,” said Jack. “If I happen to conserve water, that’s fantastic, but most of the new high-technology methods are conserving water.”

Salton Sea Restoration Program

The east side of the Salton Sea was the final stop on the Imperial Valley tour. Board members got an update on restoration efforts, including the 500-acre Red Hill Marina Wetlands Project, one of the first Salton Sea Management Program projects.

Representatives from the California Department of Water Resources, the California Department of Fish and Wildlife, and the Imperial Irrigation District described how the area was once a prime bird-watching location before the Salton Sea began receding. The 500-acre project will decrease dust emissions by creating a shallow marine habitat using water from the Salton Sea and a nearby river.

The project is a partnership between the federal and state government, and the Imperial Irrigation District – with a portion of the funding coming from a federal assistance program that the Quantification Settlement Agreement Joint Powers Authority helped fund. Work is expected to be completed by the end of this year.

The Imperial Valley tour, which highlighted the partnerships between San Diego and Imperial County, was part of an on-going series of tours led by the Water Authority’s Colorado River Program.

New Inspection Tool Aids Vallecitos Pipeline Assessments

/in , /by

A new pipeline inspection tool being used by contractors working for the Vallecitos Water District to determine pipeline integrity could become a standard tool saving time and money.

After nearly completing construction in 2008, developers walked away from the 500-acre High Point subdivision in the City of Escondido. Water facilities installed for the subdivision were left unused for ten years.

Two developers CalWest and TrueLife Communities recently decided to complete the project. They approached Vallecitos to determine what is needed to complete water service.

The mains for the project, made of ductile iron pipe, had not been used for ten years. Vallecitos needed to determine the condition of the pipes. Infrastructure Engineering Corporation and subcontractor PICA Corporation are now testing and assessing the integrity of the water main including the pipeline appurtenance (blow-offs, air vacs, and fire hydrants) connections to the main pipeline.

Early damage detection prevents pipeline failures

Several processes are included in the High Point Pipeline Assessment project. Crews insert a tool developed by PICA Corporation called a “SeeSnake” into the pipeline, and data indicates the condition of the pipes. The SeeSnake uses an electromagnetic method on iron pipes, which can “see” past cement mortar, epoxy, or polyethylene lining to detect and size any corrosion damage to the iron structure of the pipe itself.

The SeeSnake tool is pulled through the pipe at 17 feet per minute, delivering data as the inspection is being performed in real-time. The technology helps expedite information, saving time and costs by accelerating the process without sacrificing attention to detail. Vallecitos is then able to assess the pipeline’s wall thickness, potential iron loss, and any other anomalies to determine the condition of the existing pipeline.

See video demonstrating the SeeSnake pipeline assessment.

“Good decisions start with good information,” said Kris Embry, PICA regional manager. “Our ultimate goal in testing this new system is to quickly and efficiently secure accurate condition assessment information, allowing the Vallecitos Water District to address any weak links and prevent potential pipeline failures long before they happen.”

When the inspection is completed, the repair process begins.

Two water pipelines are being inspected for the condition analysis, one running along Woodland Heights Glen starting at Briar Patch Glen, and one running along Elderwood Glen, totaling approximately 3,067 feet. The larger 2,300 feet section of pipe is near the District’s existing Palos Vista.

Preventive measures save water and costs

Over time, pipelines are exposed to corrosion from aggressive soils, electrical currents, damage to coatings or linings, physical force, or other factors. The result could be a pipeline break which could case other infrastructure damage, interruption to water service, a loss of water, or monetary losses.

When an inspection finds corrosion, the affected section of iron pipeline is isolated, removed, and replaced by PVC pipe. Because iron pipelines can be susceptible to corrosion from multiple causes, they are no longer installed in the Vallecitos Water District.

The inspection found two badly corroded areas of pipeline and excavations verified the accuracy of the data. The Vallecitos Water District continues testing the new process and the accuracy of the data to determine whether to adopt the new technology for future working pipeline assessments.
