Otay Water District Invests in Preventive System Maintenance

/in , /by

As part of its preventive maintenance program to safeguard its water supply and reduce water loss, the Otay Water District is conducting leak inspections of its pipeline system. Leak detection and repair programs save water by ensuring water system integrity. The District uses state-of-the-art equipment to inspect its water distribution system for leaks in pipelines, meters, and valves. The equipment is designed to “listen” for leaks and can pinpoint the location of even the smallest water leak. Once identified, crews will schedule the needed repairs.

Otay’s contractor, Utility Services Associates, will inspect approximately 173 miles of potable water mains in Rancho San Diego, El Cajon, and Jamul, along with potable and recycled water mains in areas of Chula Vista. The work is now underway.

Water leaks often account for a substantial portion of lost revenue in water utility systems. If just small single-digit percentages of water carried by the Otay Water District’s pipelines were lost to leaks, it would cost hundreds of thousands of dollars per year and waste a precious resource.

Otay Water District customers may see workers inspecting the meter in front of their home or business, typically between 7 a.m. and 5 p.m., Monday through Friday. Some weekend and night work may also be required. The duration of the inspection can range from a few minutes to one day.

Workers will be wearing a Utility Services Associates logo and carry company identification. They will not need access to customers’ homes or property but may contact customers if they need to momentarily shut off their water supply for further testing. They will not shut off the water supply without permission from someone at the home or property.

Workers may be lifting water meter covers, inspecting, and attaching equipment to meters or valves. If a leak is suspected, the Otay Water District will contact the customer and advise them of the potential leak.

The inspection has an estimated completion date of Friday, April 29, 2022, subject to weather and other circumstances.

Customers with questions on the Leak Detection Program can contact Otay Water District’s customer service representatives at (619) 670-2222.

New Video Highlights Olivenhain Municipal Water District Achievements in 2021

/in , /by

In its ongoing effort to keep ratepayers and the community informed, the Olivenhain Municipal Water District produced its first “Year In Review” video report for 2021.

The video showcases key achievements of the District, using an accessible digital video format to share details, images, and key facts with ratepayers through a familiar, trusted online platform posted to the District’s YouTube channel.

“Most customers are not aware of the numerous projects and developments ongoing at OMWD, so this video is a great way to package all our wins into one place for easy viewing,” said Joe Jansen, OMWD administrative analyst.

Jansen said many of the District’s fiscal accomplishments aren’t readily visible to the public like infrastructure projects.

“Videos are great informational tools to help keep our residents informed of everything we do and to help build trust with us as their water provider,” said Jansen.

Eight achievements highlighted in the video

  1. OMWD received an AAA bond rating from Fitch Ratings.
  2. OMWD received over $3.6 million in refunds to be credited to customers over the next several years. Funds will be added to the Rate Stabilization Fund and applied as a direct credit to customers’ water bills over the next several years.
  3. OMWD achieved over $1.3 million of state and federal grant funds. Funding will offset the costs of important projects for ratepayers.
  4. OMWD continues to receive the highest recognition from industry groups. Awards recognize the District for its fiscal governance and infrastructure projects.
  5. Water quality continues to exceed state and federal standards. In addition, due to preventative maintenance, overall water loss decreased in 2021.
  6. OMWD completed a pilot study on developing a local water supply through groundwater desalination. Results were favorable from the grant-funded project and the District will continue to assess the project’s feasibility.
  7. OMWD completed several replacement and upgrade projects at its 4S Ranch Water Reclamation Facility.
  8. Proactive measures were taken to combat the spread of COVID-19. As a result, OMWD had no interruption to customer service and has completed all vital projects during the past year.

Joint Project By Olivenhain MWD and City of Encinitas Reaches Final Phase

/in , /by

The El Camino Real Potable Water Pipeline Replacement and Green Bike Lane Striping Project has reached its final stage. After the Olivenhain Municipal Water District Board approved filing of a notice of completion for the pipeline portion of the project, the City of Encinitas will finish restoring the street and complete new bike lane striping.

The original pipelines were installed in 1961 and 1974 and fast approaching the end of their lifespan. OMWD replaced approximately 4,700 linear feet of existing 12-inch diameter potable water pipeline along North El Camino Real from Encinitas Boulevard to Garden View Road, and approximately 650 linear feet of existing 12-inch diameter pipeline between Via Molena and Mountain Vista Drive. Water service lines and fire hydrant laterals served by the existing pipelines were also replaced.

The pipeline replacement will reduce water loss and prevent emergency shutdowns due to leaks. This is vitally important for water conservation and to ensure water supply reliability for businesses and residents, more important than ever due to drought conditions in the region.

“Proactive maintenance is a big part of what we do,” said Olivenhain Municipal Water District Board President Larry Watt. “Replacing aging infrastructure before it breaks helps to avoid emergencies, which are more costly and more impactful to customers.”

Coordination minimizes community inconvenience

To mitigate the impact to the surrounding community, OMWD coordinated with the City of Encinitas on its green bike lane project along the same route. The District implemented the lane restriping portion of the project on behalf of the City of Encinitas concurrently with the pipeline replacement project as an efficiency measure.

As a result, the two agencies combined what would normally be two separate, unrelated infrastructure improvement projects into a single effort to improve operational efficiency and reduce the temporary inconvenience of disruptions to area residents and businesses.

The bike lane will provide traffic calming measures, including improvements to safety and mobility for bicyclists along North El Camino Real from Encinitas Boulevard to Leucadia Boulevard by restriping and narrowing travel lanes. In addition, green-colored striping will augment some areas on the bike lanes and new signage and pavement markings will be installed.

“It was very important to us from the outset of the project to mitigate its impacts to the community, while also keeping costs down,” said Watt. “To that end, the partnership with the City of Encinitas was critical. They coordinated closely with us every step of the way.”

At the start of the project, the City of Encinitas requested that work be done at night to further reduce traffic impacts. Capitalizing on the reduced traffic as a result of the statewide stay-at-home order, OMWD was able to shift construction to the daytime for a portion of the project. Working during the day is more efficient and safer than night work, and minimized noise impacts to the surrounding neighbors. However, as traffic returned to normal levels, the City shifted work hours back to overnight.

New bike lanes due by December

The final work effort will include buffered bike lanes on the east and west, and fully restoring three lanes of traffic. Work is anticipated to occur through early December. Traffic controls will be in place during the day and at night with the most significant work occurring at night. Residents and businesses should anticipate lane closures and consider alternative transportation routes.

Manchester Pipeline Projects Begin with Replacement of Potable Water Pipeline

/in , /by

Encinitas, CA — Olivenhain Municipal Water District is beginning construction this week to replace aging water infrastructure near the intersection of Rancho Santa Fe Road and Encinitas Boulevard.

OMWD takes a proactive approach in repairing and replacing aging water infrastructure. These proactive measures help prevent disruptive and costly main breaks to ensure continued water service to customers. The pipelines that will be replaced are approaching the end of their lifespan. The pipelines were originally installed in 1961.

Vallecitos Water District Taps Tech for Pipeline Inspection

/in , /by

The Vallecitos Water District is using a specialized camera and sonar to evaluate the condition of a sewer pipeline between San Marcos and Carlsbad.

The Land Outfall West pipeline is a large sewer line that stretches from El Camino Real to the Encina Water Pollution Control Facility in Carlsbad. Originally installed in 1986, an evaluation of the pipeline’s current condition using closed-circuit TV (CCTV) cameras and sonar will help the District identify and prioritize its ongoing pipeline renewal and maintenance activities.

Inspections help ensure system reliability

The pipeline ranges in size from 24-inches to 54-inches in diameter and is approximately 3.2 miles long. Project Manager Susan Bowman said today’s technology allows the District to perform thorough inspections without digging up streets and disrupting neighborhoods.

“We want to make sure the pipeline is still in good shape,” explained Bowman, who is the District’s asset management supervisor. “We’re going to be taking a look at the inside of the pipe using an advanced CCTV tool. It looks at all of the insides of the pipeline and identifies any flaws or maintenance issues that may need to be addressed.”

Bowman said the District regularly inspects manholes and performs routine inspection activities. Using cameras and sonar will provide more detailed information to help the District plan ongoing maintenance and repair to ensure the pipeline will continue to perform well.

District staff, consulting staff, pipeline inspectors, and environmental inspectors will be onsite during the work. Work started at the east end of the pipeline in Carlsbad, and will follow along Palomar Airport Road under Interstate 5, and end at the Encina Wastewater Treatment Plant.

Cost-effective and less disruptive

To minimize traffic impacts and to take advantage of lower flow levels, all work is scheduled at night between 9 p.m. and 6 a.m. and will occur on weekdays through June 18. Bowman said most of the work should have limited impact on businesses and residents in the area, with minor compressor noise and limited street blocking along Palomar Airport Road.

Pipeline inspections tap tech

“We want to be good neighbors,” said Bowman. “But it is critical to ensure a pipeline is performing well, it is safe, and it is able to continue to do its job. It’s a cost-effective way to ensure the District’s assets are performing well. The technologies have really improved in the last 15 to 20 years.”

Previously, the only way to inspect a pipeline was to take it out of service and dig it up.

“If you’re going to dig something up to see what shape it’s in, you might as well be replacing it,” said Bowman. “We are definitely looking at a lot of these different noninvasive type of technologies. It helps the system perform better by reducing unplanned emergencies which are disruptive to all of us.”

Water Main Breaks Decline in San Diego for Fourth Year in a Row

/in , /by

Increased maintenance efforts by the City of San Diego of its water system infrastructure is paying off for ratepayers. For the fourth year in a row, the number of water main breaks has decreased in the City of San Diego. Thirty-three water main breaks were reported in 2020, the lowest total in more than 15 years.

The City credits its aggressive multi-year program to replace aging pipelines for bringing the numbers far below the peak of 131 breaks in 2010.

“The City’s Public Utilities Department has worked very hard to improve the reliability of our water system infrastructure,” said Shauna Lorance, director of public utilities. “Our citizens benefit greatly from fewer main breaks because it means less water loss and lower emergency repair costs.”

Fifty-five miles of pipeline replaced in next four years

San Diego’s continuing program to replace old cast iron water mains has played a major part in the decrease in breaks. Some cast-iron pipes had been in service for more than a century. Since 2013, the city has replaced approximately 180 miles of water pipelines. By 2025, the last 55 miles of cast iron water mains are scheduled to be replaced with water mains made of durable polyvinyl chloride.

Water infrastructure maintenance programs also deliver a benefit to our region’s overall economy. According to the Economic Policy Institute, $188.4 billion spent on water infrastructure investments over five years would yield $265 billion in economic activity and create 1.9 million jobs.

“Improving and maintaining our water infrastructure is an important part of our commitment to serving our customers,” said Lorance. “We will continue to provide reliable water services our customers deserve.”

Vallecitos Water District Valve Maintenance Program Ensures Reliable Service

/in , /by

Just as owners perform routine maintenance to keep their cars running smoothly, water systems need regular maintenance to provide reliable service. The Vallecitos Water District’s Valve Maintenance Program ensures these vital components in its water distribution remain in good working condition throughout the District. Valves left without proper maintenance for long periods can become a serious problem, especially in an emergency water shutdown.

VWD’s Construction Department manages the program. Two-person teams use maps to familiarize themselves with the location of the 4,959 valves in the system, not including fire hydrants and fire services. Critical valves serve hospitals and businesses. Between 300 and 500 valves are serviced monthly, following American Water Works Association standards.

Small but vital parts monitored

Construction worker Justin Shutt explains valves are isolation and shutoff point for water mains along streets.

“If we have a main break, where a main ruptures, we need to be able to isolate those certain sections without taking too many people out of water” by shutting the valves, said Shutt.

Valve Maintenance Technician John Truppa runs the valve maintenance program. He trains crew members how to use the valve exerciser machine, read maps properly, and respond to customer calls. Customer service is a priority. When a customer reports a water line leak in their home, the valve maintenance crew helps by shutting off the water at the meter.

The Vallecitos Water District’s geographic information system provides a written record of valve location, condition, maintenance, and inspection records for each valve serviced. Reliable recordkeeping is vital to ensure all valves receive regular maintenance and are replaced before coming to the end of their service life to reduce the percentage of failures and inoperable valves. The District monitors valve life span to replace them prior to failure. Areas prone to water main breaks and valves on mains serving large groups of customers get added attention.

Taking turns

Valve maintenance involves performing a prescribed number of turns to “exercise” or test the valve. Turns are calculated in part by the size of the main. Larger transmission water mains require more valve turns, both up and down. Turning speed is also important. If valves are closed too quickly, it creates “water hammer,” or sudden pressure forcing water down the line, potentially triggering water main breaks. You may have heard a water hammer in your house when you shut off a household valve suddenly.

Regular valve maintenance prevents unanticipated shutdowns of water service to Vallecitos customers.

“We want to take as few people out of water at a time as we possibly can,” said Shutt. “We keep up on the upgrades and make sure the valves are working the way they’re supposed to.”

The proactive approach by the Vallecitos Water District ensures the reliable delivery of quality water to its customers while ensuring all systems are working properly.

Residents are kept up to date on construction impacts to streets and other infrastructure through several outreach efforts including an interactive construction map, detailed online schedule, regular newsletters, and virtual open house presentations live on the City of Oceanside’s YouTube channel, offering residents the opportunity to ask questions.

“We understand living and commuting near a construction site is not easy,” said Cari Dale, water utilities director for the City of Oceanside. “Everyone involved with the project is thankful to those residents and business owners who live and work in the construction zone for their patience and cooperation. It is crucial to the successful on-time completion of this vital infrastructure project.”

Pipeline construction

Pipeline installation is now taking place at North River Road and the Douglas Drive intersection, and moving towards Pala. Lane closures on Douglas Drive allow access to the businesses through the entrance on North River Road.

In addition, pipeline installation on Pala Road is now underway. The road will remain open both ways but will require lane closures.

Well construction, which includes injection and monitoring wells, requires closing a section of Coco Palms Drive (south of Cherrystone Street), which will reduce construction time and impacts to nearby residents. Well drilling will continue 24 hours a day, seven days a week for approximately three weeks until early 2021. During this time, 16-foot sound walls have been installed around the drilling site to direct sound waves up into the atmosphere and away from residents. Night construction lighting will also be mitigated by the sound walls.

After drilling is complete, additional work will be conducted for testing and to install well infrastructure. The post-drilling work will take place weekdays during business hours and occasional Saturdays.

River Bike Trail remains open

Olivenhain Social Media Solves Water Infrastructure Mysteries

/in , /by

If you’ve ever driven past pipes sticking out of the ground and wondered, “What is that thing?” you aren’t alone. While sitting at a red light one day, Olivenhain Municipal Water District Customer Services Manager John Carnegie glanced at a pipe and realized there were probably members of the public who are unaware of the role key water infrastructure objects in their neighborhoods play in delivering safe, reliable water.

“OMWD’s #WhatIsThatThing social media campaign is a great way to inform our customers who may be unaware of all the water and wastewater infrastructure around them,” said OMWD Board Secretary Bob Kephart. “It’s a fun way to create a better understanding of the district’s work.”

Water infrastructure mysteries

“It’s easy to forget the long path it takes to get safe and reliable water to your tap,” said OMWD Board President Ed Sprague. “Most people think only as far as their water meter, not to the infrastructure all around them.”

Posts feature a photo and description provided by Olivenhain field service technicians who are out in the district working on service assignments. District spokesman Arman Tarzi says they pass contributions along when they see something the public might want to know more about.

“Our field services staff are happy to contribute ideas and are strong partners in this project,” said Tarzi.

#WhatIsThatThing provides community education

Tarzi said the images help members of the community understand how infrastructure in their area functions.

“For example, you might see a pipe with water coming out of it, and think its leaking,” he said. “But it may be a vault relief doing its job properly, so the social media campaign can help relieve concerns while providing information in a fun way.”

Tarzi said as the public increasingly engages in outdoor activity during the COVID-19 pandemic, the public may be curious of all the infrastructure around them, which is maintained by OMWD’s essential employees.

“The #WhatIsThatThing creates an appreciation for everything OMWD does to build and maintain our water infrastructure,” said Kephart. “With these posts, we are showing that water infrastructure is everywhere and OMWD is always proactive in maintaining our system.”

#WhatIsThatThing? Inside this tan enclosure is a 2-inch Air Relief Valve that is installed on the distribution water main. The purpose of this valve is to release air pockets that collect at each high point of a fully pressured pipeline. Water infrastructure is all around you!

Lake Poway Water Level Temporarily Reduced for Maintenance

/in , /by

Lake Poway’s water level is lower today, but it isn’t due to the current heatwave. The lake is being temporarily reduced to complete a planned maintenance project to replace a transducer.

Lake Poway serves as the City of Poway’s main water storage reservoir, with a capacity to hold more than one billion gallons of water. A transducer measures the lake’s water level and remotely sends data to the city.

The city typically takes advantage of lower summer lake levels every year as part of a process to maintain the water quality and for maintenance.  Water drawn down from Lake Poway is sent to the Lester J. Berglund Water Treatment Plant for treatment. Replacement water is added back in from supplies the city purchases from the San Diego County Water Authority.

Drinking water is not being discarded. Instead, the City of Poway is moving drinking water into the delivery system for treatment, and holding back on replenishing the lake until the maintenance project is complete.

The work creates a bonus for San Diego County’s avid fishing fans.

“It’s not unusual for the water level to be down in the lake this time of year,” said Allie Margie, Recreation Supervisor at Lake Poway. “Our night fishing and catfish restocking schedule aren’t affected – and with less water and more fish in the lake, your chances of making a catch might be better than ever.”

Three billion gallons of drinking water safely treated annually

Poway operates a modern water treatment and distribution system. Lake Poway serves as a storage reservoir for imported water from both the Colorado River and Northern California.

Water flows through the Berglund Water Treatment Plant, where approximately three billion gallons of drinking water are treated every year for the citizens of Poway. Once treated, the drinking water enters a system of pipes, pump stations, reservoirs for delivery to customer’s homes and businesses.

Did you know?

  • The City of Poway maintains about 294 miles of water pipe.
  • There are approximately 2,345 fire hydrants throughout the city.
  • There are over 5,044 valves in the water system.
  • Employees working in the water system are required to be certified by the State of California to work in a water system.
