National Awards for Pure Water San Diego’s John Carroll

John Carroll, the City of San Diego’s Pure Water Treatment Plant superintendent, received the 2021 Robert O. Vernon Membrane Plant Operator of the Year Award from the American Membrane Technology Association and the American Water Works Association.

This award recognizes outstanding contributions to water supply improvement by an individual working at a membrane filtration, desalination, and/or water reuse facility. Carroll was selected in recognition of his service and dedication to membrane operations and for his leadership within the industry.

“My selection would not have been possible without the support of many dedicated and talented individuals, the fellow coworkers, consultants, and volunteers to whom I owe all my success,” said Carroll.

Carroll worked as the senior wastewater operations supervisor of the North City Water Reclamation Plant, where he oversaw the operation of the City of San Diego’s Pure Water Demonstration Facility.

“When Pure Water came along, we needed staff to step up,” said Tom Rosales, Assistant Director for the San Diego Public Utilities Department. “John established protocols and procedures. He participated in training incoming staff. He led public tours. I can’t overstate his involvement from day one.”

From student to teacher

“Since I had no operational experience with Advanced Water Treatment technologies prior to my role at the City’s Pure Water Demonstration Facility, my approach was that of a student, with the caveat of knowing I would need to become a teacher out of necessity to build our internal knowledge,” said Carroll.

In July, Carroll was promoted to be the first superintendent of the North City Pure Water Facility, currently under construction. It is the latest step in a career that started with a part-time job in the City’s Lakes Division. He studied water and wastewater treatment at Palomar College and completed the Water Authority’s Regional Water/Wastewater Internship Program in 2009, launching his career with the City of San Diego in plant operations.

“The encouraging and supportive public servants I’ve met throughout my career continue to add to my sense of community here,” said Carroll. “Ultimately, I like to think I am following in my mother’s footsteps who worked at the City’s Otay Water Treatment Plant.”

Each year, AMTA confers multiple awards to recognize exceptional individuals and organizations like John Carroll and Pure Water San Diego for their efforts in advancing the understanding and application of membrane technology to create cost-effective and reliable water treatment solutions.

“This is a national award,” noted Rosales. “John’s peers and others agree that he’s deserving of this award. You want someone like John to be on your team to stand it up and lead it.”

“Membrane technology continues to make considerable advances in creating safe, affordable and reliable water treatment solutions because of industry innovators and a dedicated network of forward-thinking membrane professionals,” said Jill Miller, AMTA President.

The award is named after the late Dr. Vernon, a professional geologist who contributed to water resources management at various levels of state and federal government in Florida and who was a former president of the American Water Works Association.

This year’s winners were announced at the 2021 Membrane Technology Conference hosted in West Palm Beach, Florida in July.

EPA Funding-East County AWP-Padre Dam MWD

EPA Funding Secured for East County Drinking Water Project

In a major milestone for water reliability, the East County Advanced Water Purification Program was awarded a $388 million federal loan from the U.S. Environmental Protection Agency to help advance the project’s completion.

Radhika Fox, U.S. EPA Principal Deputy Assistant Administrator for the Office of Water, joined Kyle Swanson, Director of the East County AWP, and Steve Goble, Joint Powers Authority Chair of the East County AWP, for the June 4 announcement at the demonstration facility for the project in Santee. Following the presentation, Fox joined local officials for a tour of the demonstration facility.

“EPA is proud to partner on this project, which uses proven technology to bolster drinking water supplies in this climate-stressed region,” said Fox. “Investing in water infrastructure is one of the best bets we can make to improve public health and the environment, create jobs and address pressing challenges that face our communities.”

The East County AWP is one of only 38 projects selected nationwide to receive a share of approximately $6 billion in federal water infrastructure investments. The Water Infrastructure Finance and Innovation Act (WIFIA) loan is the second-largest loan awarded to any San Diego County project.

“The East County Advanced Water Purification Program is the result of many years of strategic, long-term planning and this WIFIA loan marks a historic milestone in its development,” said Allen Carlisle, CEO and general manager of Padre Dam Municipal Water District. “By providing East County with local control and independence of both its wastewater and water, the program secures a long-term solution for increased stability in our communities and safeguards the vitality of our economy and quality of life. We are grateful to the U.S. EPA for partnering with us on this important program and investing in future generations.”

New, local, sustainable water supply

The East County AWP is a collaborative partnership between the Padre Dam Municipal Water District, Helix Water District, County of San Diego, and City of El Cajon. It will create a new, local, and sustainable drinking water supply using sophisticated technology to provide 30% of current drinking water demands for East County residents when it is completed in 2025, as much as 11.5 million gallons per day.

The project will recycle East San Diego County’s wastewater locally and purify the recycled water at a new 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.

Padre Dam Municipal Water District currently imports 100% of its drinking water supply. The agency treats two million gallons per day at its water recycling facility for irrigation and non-potable uses. Helix Water District imports approximately 85% of its drinking water supply with the remaining coming from local sources.

In addition to providing a new local water supply, the project will eliminate the need to send most of East County’s wastewater to the City of San Diego’s Point Loma Wastewater Treatment Plant, where it is currently treated and then discharged into the ocean. Keeping this water resource in east county provides water sustainability and it’s good for the environment.

San Diego Starts Monitoring Wastewater For Virus

San Diego is participating in a statewide program to monitor its untreated wastewater for the virus that causes COVID-19, it was announced Tuesday.

City staff have been monitoring for severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2, in untreated wastewater at the Point Loma Wastewater Treatment Plant this month.

Sanitary Wipes Suspected Cause of $190K Damage to Water Treatment Plant

Cornwall City Council approved paying $187,273 from the Wastewater Works Reserve to cover damages to the Waste Water Treatment Plant.

On Saturday, May 16, 2020 alarms notified staff at the WWTP that a traveling bar screen was not operating. The lower screen had been blocked and began to back up, which lead to an excess of 2,000 cubic meters of raw sewage spilling out into the St. Lawrence River.

Benefits Bubble Up: Wastewater Treatment

What makes Bear Republic Brewing Company special is just how conscious its chief operating officer and master brewer is of water’s impact on the business and its local community.

Bear Republic was established in Sonoma County, California, in 1995 by the Norgrove family, and opened its first brew pub in January of 1997 in Healdsburg, California. In November of that year, Peter Kruger was hired to the company, launching his career path to his current position as Bear Republic Brewing Company master brewer and chief operating officer.

At the time he was hired, Kruger said the wastewater from the beer making process was sent through the sewer system to the municipal wastewater treatment plant.

Wastewater Treatment Operator Featured As ‘Water Utility Hero’

Last week Escondido’s Wastewater Treatment Plant Operator, Carrie Selby was featured as the Water Utility Hero of the Week by the San Diego County Water Authority SDCWA. Shelby was interviewed for the Water News Network and talked about her career and work life during the pandemic.

Construction near San Marcos homes required creative thinking and community cooperation from the Vallecitos Water District to successfully complete the project. infrastructure

Community Outreach Makes Challenging Infrastructure Update a ‘Walk in the Park’

In its efforts to maintain its critical infrastructure, the Vallecitos Water District undertook a challenging update to a wastewater system pipeline constrained by its precarious location.

The existing eight-inch gravity sewer pipeline conveys wastewater from the intersection of Rock Springs Road and Bennett Avenue west through a greenbelt area to an existing 12-inch pipeline in Rock Springs Road at Lancer Park Avenue. To expand capacity for current and future growth, it was replaced with a new 15-inch PVC pipe west of Matthew Lane and a 12-inch PVC pipe north and east of Matthew Lane.

The District always prefers to perform work in a street or public right-of-way. Neither were possible for this project due to its greenbelt and park location within feet of residential homes.

“We took every environmental precaution prior to construction,” said Lito Santos, Vallecitos Water District Project Engineer. “We performed a nesting survey, a raptor survey, and we also worked to tunnel under the bridge,” within the Environmental Protection Agency’s “Clear Water Rule.”

San Marcos Woods Homeowners Association board member Ross Fisher acted as a liaison between homeowners and the HOA with the District. Fisher expressed concern about access to the work area by the District’s large combination truck. The original proposal to create a concrete strip to drive over wasn’t feasible.

Working together with Vallecitos Water District engineers, the group chose an alternative material called “grass-crete.” Grass-crete is a green porous paving solution that comes in easy-to-install rolls. It’s flexible, lightweight, durable and provides design versatility to the project. Due to its incredible strength, the grass-crete and existing lawns can handle the weight of a large service vehicle driving on it without significant damage.

Proximity to additional threats

Manholes were waterproofed, coated, and sealed as an additional precaution and to extend their longevity.

Vallecitos Water District engineers also worked with San Diego Gas & Electric to perform its work with enough safety clearance from a 16-inch transmission main artery gas line pressurized at 800 pounds per square inch. The District secured permission to dig within two to three feet from the line instead of the standard five feet.

The work area is also prone to flooding after large rain events, raising the water levels in the nearby creek high enough to infiltrate and inflow into the manholes. The District moved the manholes clear of the creek embankment, and lifted the manholes two feet above ground and clear of the flood plain to prevent runoff intrusion. Manholes were waterproofed, coated, and sealed as an additional precaution and to extend their longevity.

“Overall Vallecitos left the greenbelt area as good or better when they started,” said Fisher of the HOA. “On a scale of one to ten, I have to give them a 9.5 or a ten. Working with the inspectors and Lito Santos the engineer, everything we asked for was done in a timely manner.”

“The project was a huge success,” said Santos. “Working with the Vallecitos Engineering Team, the Inspection Team and Mr. Fischer, it was not just a Vallecitos highlight but a career highlight.”

Vallecitos Water District Employs Technology to Decrease TSS, pH and Algal Blooms

Vallecitos Water District provides 5.25 million gallons of recycled water for irrigation every day. To fulfill the demands of modern irrigation systems, it is important to maintain low TSS levels. This is a challenge during the warm months in California, as algae that occur with raising temperatures, increase the level of TSS and clog the filters that are meant to remove TSS before the distribution of water to the irrigation systems.

Vallecitos Water District is known for its’ sustainable and innovative focus when it comes to water and wastewater treatment.
