Southern California Edison signed seven contracts for a total of 770 megawatts of lithium-ion battery-based energy storage — to enhance the regional grid’s reliability and replace four large coastal once-through cooling plants.
It’s one of the nation’s largest energy storage procurements and an indication of utility acceptance of massive-scale battery storage. Late last year, the California Public Utilities Commission urged California’s power providers and community choice aggregators to procure 3.3 GW of storage and PV-plus-storage systems to solve grid congestion and to compensate for gas and coal plant retirements.
Remarkably, SCE wants these energy storage resources online by August 2021, an aggressive timeline unthinkable for any type of fossil fuel project of this size.
The coronavirus pandemic forced the City of Escondido’s Water Quality Laboratory to rethink its lab operations without compromising community health or employee wellbeing while ensuring the clean, safe, and efficient operation of the city. Through teamwork and creative thinking, the lab found success in maintaining its essential work.
“Whether we have a pandemic or not, people still want to open their taps and have clean drinking water,” said Ralph Ginese, supervising chemist with the City of Escondido.
Hale Avenue Resource Recovery Facility Laboratory Superintendent Nicki Branch says employee safety was addressed first.
“We immediately enforced the six-foot social distancing requirement and frequent handwashing,” said Branch. “The facility cleaning staff increased disinfection wipedown of all surfaces. We stopped having group staff and safety meetings by switching to online. We have changed our work schedule, essentially cutting it in half on a rotating schedule and allowing all employees to be able to telecommute from home periodically.”
The 14 employees have been provided additional personal protective equipment including facemasks.
“Staff is able to do administrative work, lab paperwork, study for exams, safety training, research on the industry and attend webinars,” said Branch.
Half of the staff members remain at the lab facility full-time, where they conduct analyses to verify the quality of wastewater treatment processes to safeguard community health, as well as required monthly and quarterly testing.
Unseasonal rainfall creates additional challenges

Recent heavy rains in Escondido complicated the testing process. Branch said several lab staff were placed on call in the event additional testing was needed due to a possible emergency-permitted tertiary discharge to nearby Escondido Creek due to high flows after five days of rain.
“They were all game to come in if needed on a Saturday to assist, but fortunately the operations staff worked miracles to keep us from discharging,” said Branch. “Heavy rains also caused a situation where additional sampling of lakes for drinking water analysis occurred, and the lab staff responded immediately to help the drinking water division with sampling and analysis.”
The Escondido lab routinely tests six sample sites along the outfall line.
“It’s a full-blown scan, so getting samples to contact labs would have been a real challenge,” said Ginese, crediting the work of the city’s operations staff to prevent any discharge into the creek.
“I am so proud of all the staff at the HARRF Laboratory for responding to this Covid -19 pandemic in a professional manner, adapting quickly to our City policies requiring social distancing, and for offering to come in on emergency situations when needed,” said Branch.
The San Diego County Water Authority and its 24 member agencies have increased regional coordination and communication to ensure the coronavirus pandemic does not impact safe and secure water service for San Diego County.
The San Diego County Water Authority is making progress on the construction of a new 5 million gallon underground reservoir in Mission Trails Regional Park. The underground reservoir is also known as a flow regulatory structure.
Classified as a “critical or essential” infrastructure project during the COVID-19 response, the project is moving forward to stay on schedule. Water Authority and contractor staff are taking heath protection precautions to maintain public safety by following COVID-19 safety guidelines, including wearing face masks, using hand sanitizers, and disinfecting fencing, work tools and equipment.
Construction preparation underway for water project
Recent work includes the installation of temporary office trailers at the east end of Clairemont Mesa Drive in the City of San Diego, delivery of materials, installation of eight-foot fencing around the major construction sites and placement of silt fencing around environmentally sensitive areas.
Topsoil is being removed and saved where digging is planned. This topsoil will be placed back in its original location after construction is done to encourage plant re-growth, help hold water and prevent soil erosion. Construction crews are working Monday through Friday between 7 a.m. and 7 p.m.
Trail closures to ensure safety of public and essential workers
Some trails in the western portion of the park are closed to ensure the safety of the public and essential workers on site. Several trail closure signs with maps have been strategically placed to help park users navigate the trails and take detours to avoid the construction area.
The project is in the western part of Mission Trails Regional Park near the Tierrasanta community. It includes building the new underground covered reservoir, a flow control facility and pipeline interconnections to upgrade the system that delivers water to treatment plants serving the central and southern areas of San Diego County. The project is anticipated to be complete in early 2022.

Seventeen above ground steel tanks and two underground concrete reservoirs play a vital role in the Vallecitos Water District’s mission to provide clean, safe, and reliable water to its 105,000 district residents. Maintenance and cleaning of the tanks and reservoirs is a critically important process.
Without regular washouts, tanks can accumulate large amounts of sediment, prohibiting proper inspections.
California State Water Resources Control Board Division of Drinking Water standards require that tanks must be cleaned every three years.
Vallecitos Water Operations’ team cleans up to six tanks annually. Regulations call for the district’s six certified water operators to empty and enter the tanks for inspection to ensure there is no structural damage or other concerns prior to the tank washout to ensure continued operation of the water distribution system. Vallecitos adheres to a strict inspection schedule as part of its preventative maintenance program.
“We want customers to know we’re being diligent protecting the water infrastructure,” said Richie Arballo, senior water systems operator. “If we find an issue where a tank needs to be refurbished, we want to correct it as soon as possible, before it becomes an emergency.”
Coordinating tank cleaning a complex operation

Vallecitos staff schedules tank cleaning during winter months when water demand decreases. Initial steps include how to best reroute water delivery while tanks are taken out of service for cleaning. After the tank is drained, water operations staff enter the tank for a thorough inspection, followed by cleaning and disinfection.
When the process is complete, staff refills the tank near its spill level and allows the water to stand for 24 hours before conducting water quality analysis. Once lab results are reported and submitted to the state’s Division of Drinking Water, it will determine when the tank can be placed back in service.
Tank cleaning began in March but was put on hold due recent rains and the coronavirus pandemic, with the the need for physical distancing. See the cleaning process depicted in this video.
Safety and environmental stewardship
During draining, water is discharged to a storm drain or dirt area where it is absorbed back into the ground naturally. Once the tank is removed from service, it is isolated from the water distribution system. Valves are secured and double-checked to be sure they are completely closed. Staff members wear respiratory protection due to chemicals used during the disinfection of the tank interior.
Cleaning and disinfecting the large reservoirs requires teamwork. The Water Operations team calls on staff from the Vallecitos Water District Collections and Construction departments to augment and support its personnel.

“When we all work together it really shows how much of a team we are here at the District,” said Shawn Askine, water systems supervisor. “We are very fortunate at Vallecitos to have employees willing to come out and help us clean the tanks properly and effectively, so we are utilizing customer dollars as efficiently as possible.”
Due to the amount of equipment and coordination required, the Vallecitos Water District created a customized trailer specifically for conducting tank cleaning. The small investment allows all required equipment to be stored on the trailer, ready to go on the day of the scheduled cleaning. The trailer and equipment significantly streamline the process and ensures all parts, fittings, and washout equipment are available to get the job done effectively.

An effort to bolster food bank supplies and fight hunger in San Diego County is getting a helping hand from the region’s public water agencies.
The San Diego County Water Authority and its member agencies are supporting a virtual food drive in partnership with the Jacobs & Cushman San Diego Food Bank. The campaign allows donors to select and purchase items such as canned meats, vegetables, fruits, peanut butter and oatmeal for distribution to needy residents. To donate, go to www.bit.ly/SDWaterAgencyFoodDrive.
The Water Authority Board leadership launched the effort for staff and Board members about two weeks ago, then expanded it by inviting 24 retail member agencies countywide to join the effort to fight hunger. So far, nearly $6,000 has been contributed through that portal, and some member agencies are setting up their own portals for their service areas.
Help fight hunger
In addition, water agencies have partnered with the Food Bank to inform its clients that it is unnecessary to purchase bottled water when convenient, clean drinking water is available 24/7 at the tap for about a penny a gallon.
“The region’s water industry is committed to sustaining our community in this time of acute need,” said Water Authority Board Chair Jim Madaffer. “The San Diego region has come together time and again to meet challenges such as wildfires, and we’re doing the same to provide hunger relief during this crisis.”
Demands for food increase during pandemic
The San Diego Food Bank typically helps feed 350,000 people each month at 200 distribution sites — and demands have skyrocketed as the economic impacts of coronavirus closures ripple across the region.
Donations to the San Diego Food Bank are tax deductible to the extent allowed by law. The San Diego Food Bank is a 501(c)(3) organization.
Essential workers on the job
In response to the pandemic, the Water Authority and its 24 member agencies have increased regional coordination and communication to ensure continued delivery of safe and reliable water service for San Diego County. Public water supplies in the region remain safe to drink due to numerous robust treatment processes used by local and regional water providers.
As essential workers, the region’s water and wastewater system employees will continue to work to ensure safe and reliable water services.

The City of San Diego’s public utilities team including water treatment plant employees continues to work to provide its customers with high-quality drinking water during the coronavirus pandemic.
Following efforts to increase safety measures throughout all City departments to stop the spread of COVID-19, San Diego Mayor Kevin Faulconer toured the Alvarado Water Treatment Plant on Friday to observe increased safety protocols. He also thanked City employees as they continue to deliver safe, reliable water to over 1.4 million San Diegans.
Increased safety measures ensure continued water supply safety

Mayor Faulconer kicked off his visit Friday morning by meeting maintenance staff on duty.
“Like many San Diegans, our City employees are adapting as we take on the COVID-19 crisis,” said Faulconer. “They’re working under increased safety measures so we can continue to deliver essential services, including a safe, clean and reliable water supply.
“I stopped by the Alvarado Water Treatment Plant today to thank the employees there and let them know how proud we are of all they’re doing to keep the water running for San Diegans.”
More than a month into the coronavirus crisis in California, water and wastewater treament employees, continue to work around the clock to deliver essential services to San Diego County residents.
“I am so grateful for the employees that come to work daily to make sure the City residents have access to a safe and reliable water supply,” said Shauna Lorance, City of San Diego public utilities director. “While you might not be able to go out to a restaurant, visit the beach or any of the usual activities all of us in San Diego have learned to enjoy, you do not have to worry about the safety of the water supply. The water continues to be treated and tested just like always.”
The San Diego County Water Authority and its 24 member agencies have increased regional coordination and communication to ensure the coronavirus pandemic does not impact safe and secure water service for San Diego County.
Treatment plants employ innovative disinfection and filtration

The City of San Diego has three water treatment plants that use several treatment methods to provide safe drinking water to the public. The plants are managed by the City’s Public Utilities Department.
San Diego’s drinking water treatment plants use a combination of innovative disinfection strategies and filtration. This multi-step process provides multiple barriers against elements that could make the city’s water unsafe or impact taste.
When the Alvarado Water Treatment Plant began operation in 1951, it replaced old water treatment plants at University Heights and Chollas Heights. Located near the Murray Reservoir, Alvarado today provides drinking water to customers in the central section of the City. Plant capacity is 200 million gallons of treated drinking water per day and is operated by 16 City employees.
A multi-phase expansion and upgrade project for the plant was completed in 2011. The Alvarado Plant began its first year of active participation in the American Water Works Association’s Partnership for Safe Water Program in 2013 and has implemented several optimizing projects.
Alvarado is also home to the City’s Water Quality Laboratory, which continuously monitors the City’s drinking water to make sure it is always safe and meets all state and federal health standards.

San Diego – An effort to bolster food bank supplies in San Diego County is getting a helping hand from the region’s public water agencies.
The San Diego County Water Authority and its member agencies are supporting a virtual food drive in partnership with the Jacobs & Cushman San Diego Food Bank. The campaign allows donors to select and purchase items such as canned meats, vegetables, fruits, peanut butter and oatmeal for distribution to needy residents.

This week, crews are installing a carbon fiber lining inside Pipeline 5 in North San Diego County between Fallbrook and Escondido. The work is essential to maintain the 96-inch pipeline that delivers untreated water from Lake Skinner in southwest Riverside County to the Lower Otay Water Treatment Plant in southern San Diego County.
The work began at the end of March when Pipeline 5 was shut down for the installation of two internal steel bulkheads. The bulkheads allow the rest of the pipeline to stay in service while work is performed in an isolated section.
“Ensuring that water supplies continue to be reliable for all of the region’s 3.3 million residents and businesses is our priority,” said Jim Fisher, director of operations and maintenance at the Water Authority. “We are performing this essential repair to one of our largest pipelines to make sure that there are no interruptions in service to our member agencies.”
The carbon fiber installation is anticipated to be complete by the end of next week. Carbon fiber is a highly effective solution to reinforce the stressed areas of the pipe and extend its lifespan.
Proactive asset management program detects issues before they arise
Pipeline 5 was built in 1982 and is a part of the Water Authority’s Second Aqueduct, which includes Pipelines 3, 4 and 5.
In August of last year, Water Authority staff detected a leak in nearby Pipeline 4 at Moosa Creek and inspected the other two pipelines at that location. During that inspection, Pipeline 5 showed signs of stress, where the operating pressure within the pipe exceeds 400 pounds per square inch. A failure of the large-diameter pipeline would cause significant damage to the environment and nearby pipelines.
The proactive and timely repair to Pipeline 5 is part of the asset management program, which is a key element of the Water Authority’s commitment to providing a safe and reliable water supply to San Diego County. Making preventative repairs to large-scale infrastructure ensures that regional water service will continue uninterrupted.
After installation of the carbon fiber is complete, a second shutdown to remove the isolation bulkheads is anticipated to take place in May, after which the pipeline will return to normal service.
Protecting the health of essential workers during COVID-19
To ensure safety and health, most Water Authority employees have been working from their homes since mid-March. For those employees who need to be at work sites, strict precautions are being taken by limiting the number of people present, maintaining physical distance, requiring all employees to wear protective gear and providing hand washing stations where possible.

Now that most of us are at home more, you may be wondering “how much more water am I using?” The good news is, it’s probably less than you think. This is because the activities that use the most water – such as outdoor irrigation, showering and doing laundry – happen at the same weekly frequency regardless if you and the family are spending your days at home or not.
Your water use will increase only slightly
Unlike our use of electricity, which we use continuously as we light our rooms, run our computers or stream shows, our use of water is more intermittent. This means that although we are home the entire time, using water may be limited to bathroom visits, washing our hands, cleaning dishes or doing laundry. This is good news for your water bill.
What about all the handwashing?
Surprisingly, washing your hands for the recommended 20 seconds does not use that much water. If you have faucet aerators or a newer faucet, each 20-second hand wash with the water running uses less than half of a gallon. Even still, faucets are responsible for 18% of the typical indoor water consumption. It takes 24 extra handwashing events per day over a 60 day billing cycle to increase your bill by one unit, which equals 748 gallons and costs you $4.98. You can use less water if you shut the faucet off while you soap up your hands, but you don’t have to. Public health is more important than water conservation. Wash your hands and stay safe.
What about additional toilet flushing?
Since you are at home and not at work, you are flushing your toilets more, this is where you may see a slight increase in your indoor use. After all, toilets make up an average of 20% of the typical indoor water consumption. The good news – it takes a lot of flushes to really increase your bill. The most common toilets in everyone’s homes use 1.6 gallons per flush, while newer toilets use 1.1 gallons per flush or less. It will take 467 flushes of al 1.6 gallon per flush toilet to use one unit of water. Note that older toilets can use 4-6 gallons per flush, and that changes the picture dramatically.
Do not flush ‘flushable’ wipes
It’s also important to note that you should not use your toilet as a garbage can. Do not flush “flushable” wipes, paper towels or disinfecting wipes down the toilet. These items wreak havoc on sewer systems. The last thing any of us need at this time is a backed up sewer.
What about the dishes from extra cooking and snacking?
You may be creating more dishes due to extra cooking and snacking, but fortunately, dishwashing does not use much water either. If you want to use less water, use the dishwasher. Dishwashers recirculate water and are highly efficient, only using 4-5 gallons per load.
Showering and laundry at home
The good news is that even though you and your family are home all day, you’re most likely not showering any more than you typically would. Showers are a larger portion of our indoor consumption, around 21 percent. The same is true for your laundry, which can be around 22 percent of indoor water use. But, not dressing for work each day may reduce your weekly laundry, offsetting increased us of water for other needs.
Our home’s ‘other half’
The big piece that is missing is what we use on our landscapes, and thankfully, this should not change. Outdoor watering is responsible for half of Helix Water District customers’ total use. So, while we may be concerned that being home will increase our indoor use, the largest potential for savings is still outdoors. An irrigation controller has more to do with the typical home’s water consumption than our indoor behaviors. If you have not been outside lately, the soil is still wet and most of us can leave our irrigation controllers in the off position for the time being.
This article was written by Helix Water District Conservation Technician Vince Dambrose, whom is currently working from home to keep his coworkers safe and healthy so that the district can keep your water flowing.
