Vallecitos Water District Training Preps Firefighters for Wastewater Plant Emergencies

North San Diego County fire agencies teamed up in November with the Vallecitos Water District for confined space training drills. The drills, held over a two-week period, prepare firefighting professionals to respond to emergencies in facilities such as wastewater treatment plants and maintain their confined space certification.

The recent training took place at the Vallecitos Water District’s Meadowlark Reclamation Facility. Firefighters saw how the wastewater plant operates while getting a walk through of the facility. Fire personnel worked with Vallecitos staff and both groups benefited from the opportunity to understand each other’s equipment and protocols.

“The confined space training with the fire agencies has helped prepare us for future scenarios that could happen at the plant,” said Dawn McDougle, wastewater plant supervisor.

The Meadowlark facility was chosen because it provided both vertical and horizontal confined spaces for training drills. McDougle suggested the facility storm wet well be used for the confined space exercise since it is relatively environmentally clean.

Eight different fire agencies trained during morning or afternoon sessions, breaking up groups for various skill set station drills. Stations included an “Arizona vortex,” a new piece of equipment fire agencies use for rescues; a review of confined space rescue equipment; and training in confined space permit requirements. Confined space permits are required by OSHA before making any kind of confined space entry or rescue.

Meadowlark staff reviewed the conditions and possible actions within filter station space with fire crews. Staff also explained decision-making for confined space entry, and conditions they might encounter, such as chemical exposure, and lock-out/tag-out requirements.

The training wrapped up with an all-hands mock confined space drill scenario at the Meadowlark storm wet well. Participants were required to respond to a simulated mechanical failure with a station pump, leaving Vallecitos staff “trapped” in a hole. First responders needed to “rescue” Vallecitos staff. Fire department personnel used the vortex system to rescue personnel trapped in the stormwater wet well. As part of the rescue scenario, fire teams incorporated Vallecitos staff involvement in the rescue mission.

Vallecitos wastewater collection crews also completed the confined space training with the firefighters.

Fire agencies were impressed with the staff and their operation of the Meadowlark Reclamation Facility. As a result of training, fire agencies can now respond more efficiently and with confidence.

“We appreciate the collaboration with fire agencies and the time they took to explain their procedures to Vallecitos District staff,” said McDougle. “We look forward to future training with the fire agencies.” 

Firefighting agencies participating in the training included crews from the cities of Carlsbad, San Marcos, Del Mar, Vista, Escondido, Oceanside, Encinitas, Solana Beach, Rancho Santa Fe, Valley Center, and crews from North County Fire (Fallbrook), San Pasqual and Rincon.

Del Mar Seeks Solutions To Preserve Beaches

California is Feuding With This SoCal City Over ‘Planned Retreat’ From Sea Level Rise

Del Mar is gearing up for a tussle with the California Coastal Commission over the best way to adapt to rising sea levels, an issue with statewide implications.

The city north of San Diego has taken the position that one of the Coastal Commission’s basic strategies, called “managed retreat” or sometimes “planned retreat,” will not work in Del Mar.

The San Diego County Water Authority’s Board of Directors celebrated the agency’s 75th anniversary.

Water Authority Celebrates 75 Years of Service to San Diego County

The San Diego County Water Authority’s Board of Directors celebrated the agency’s 75th anniversary during today’s Board meeting, which included 20 proclamations honoring the agency for its service to the region dating back to 1944.

Cities across the region joined the state Assembly and Senate, the San Diego County Board of Supervisors and other state and local leaders to formally mark the occasion. The San Diego City Council and the San Diego County Board of Supervisors even proclaimed today “San Diego County Water Authority Day” in honor of the agency’s legacy of water supply reliability.

75 years of service

“Starting with the historic first water deliveries in the 1940s, the Water Authority has partnered with our member agencies to build, operate and maintain the vital infrastructure that supports our region’s $231 billion economy and unparalleled quality of life,” said Board Chair Jim Madaffer. “Our collective investments have created extraordinary advances in water supply reliability that are sustained by the daily vigilance necessary to operate and maintain such a complex system.

“While today we celebrate the past, the Water Authority and its 24 member agencies continue to focus on the future by fostering innovative solutions to ever-changing water resource challenges,” Madaffer said. “Together, we will supply the San Diego region with safe and reliable water supplies for generations to come.”

Since 1991, the Water Authority and its 24 member agencies have deployed one of the most aggressive water supply diversification strategies in the nation to improve regional water supply reliability. In the years ahead, member agency projects will play an increasingly important role in continuing to ensure reliability for the San Diego region.

Forward thinking on water

The Water Authority’s current forward-thinking efforts include developing water storage capacity in Lake Mead to provide additional drought resilience for San Diego and the Southwest.

The agency also is working closely with the City of San Diego to assess a potential pumped storage project at San Vicente Reservoir that could help meet clean energy goals and benefit water ratepayers. In addition, the Water Authority is analyzing the costs and benefits of a regional water conveyance system that could help San Diego County and the entire Southwest to more effectively manage water resources.

Profound impact

During today’s ceremonies, water agency, civic and business leaders noted the Water Authority’s profound impact on the San Diego region and wider water issues over the past 75 years.

  • “A reliable water supply is critical for San Diego’s regional economy and for maintaining a competitive business climate. The business community applauds the Water Authority and its 24 member agencies for their leadership, and for increasing the county’s water supply reliability with investments that keep our economy growing.” — Mark Cafferty, president and CEO, San Diego Regional Economic Development Corp.
  • “It is a pleasure to celebrate the San Diego County Water Authority’s 75th anniversary. We share a common history and a common vision for water supply reliability that has been essential to the economic vitality and prosperity to all San Diegans. We look forward to strengthening our relationship to meet the future needs of San Diegans.” — Gloria D. Gray, chair, Metropolitan Water District Board of Directors
  • “Farming is a foundational piece of our regional economy and quality of life – but it doesn’t happen without a reliable water supply. Our farmers are constantly innovating to use water more efficiently by adopting new technology and planting more-efficient crops.” — Eric Larson, executive director, San Diego County Farm Bureau
  • “On behalf of the Imperial Irrigation District Board of Directors, I salute the San Diego County Water Authority on its 75th anniversary. Our two agencies are partners in the nation’s largest agriculture to urban transfer and in the process, we have forged a durable alliance at the Salton Sea. It is a relationship that the IID highly values.” — Erik Ortega, president, Imperial County Irrigation District Board of Directors
  • “By combining a diversified set of water supply sources with greatly enhanced storage capacity, we are developing a more robust safety net for San Diego County.” — Jerry Sanders, president and CEO, San Diego Regional Chamber of Commerce

On June 9, 1944, San Diego voters approved the Water Authority’s formation under the County Water Authority Act. Imported water arrived three years later to slake the thirst of a growing population just weeks before local supplies would have run out.

The modern era of the Water Authority started during deep, drought-induced water supply cuts in the early 1990s. Since then, Water Authority and its 24 member agencies have deployed one of the most aggressive water supply diversification strategies in the nation to improve regional water supply reliability.

At the same time, the agencies have aggressively helped to reduce per capita water use so that the total regional water use today is well below 1990 levels despite significant growth in the population and economy.

75th anniversary milestones

The Water Authority reached several major milestones over the past two decades. They include:

  • In 2003, Olivenhain Dam was the first major new dam built in San Diego in more than 50 years. At 318 feet, it was the tallest roller-compacted concrete dam at the time.
  • In 2008, the Twin Oaks Valley Water Treatment Plant north of San Marcos began operations. It was the largest submerged membrane water treatment plant in the world when it was commissioned.
  • In 2011, the San Vicente Tunnel and Pipeline Project – an 11-mile long, 12-foot diameter tunnel with an 8-1/2-foot diameter pipeline – created a link from the City of San Diego’s San Vicente Reservoir to the Water Authority’s Second Aqueduct, greatly improving the Water Authority’s ability to distribute water and store water in the reservoir.

  • In 2012, the Lake Hodges Hydropower Facility started serving the dual purposes of connecting the lake to the Water Authority’s aqueduct system and generating 40 megawatts of clean, on-demand electricity.
  • In 2014, the San Vicente Dam Raise Project, the tallest dam-raise project in U.S. history, expanded the reservoir’s capacity by more than 157,000 acre-feet.
  • In 2015, the $1 billion Claude “Bud” Lewis Carlsbad Desalination Plant, distribution pipeline and related facilities started commercial operations as the largest seawater desalination project in North America.
  • The Water Authority’s Asset Management Program, which includes a multi-year project to reline 82 miles of large-diameter prestressed concrete cylinder pipelines with new steel liners, helps to prevent pipeline failure and extend their lifespans by 75 years or more at significantly less cost than traditional pipeline replacement programs.
