The atmospheric river that deluged San Diego last week followed close on the heels of enormous waves that punished the California coast at the beginning of the year, with both weather events setting off alarms in more ways than one.
Local utilities are looking for new ways to make Southern California earthquake safe, and one way is by replacing aging water pipes.
The new pipes could help keep the water flowing after a big one hits. LADWP is replacing critical areas along its 7,000 miles of water pipes in Los Angeles with earthquake resilient pipes to ensure water is still flowing after the shaking stops.
East San Diego County firefighters and first responders will be better prepared to respond to emergencies due to improved communication capacity through a new partnership with the Helix Water District. The Heartland Communication Facility Authority recently installed a new radio repeater on Helix Water’s Calavo tank, located near Mt. Helix.
East San Diego County firefighters and first responders will be better prepared to respond to emergencies due to improved communication capacity through a new partnership with the Helix Water District. The Heartland Communication Facility Authority recently installed a new radio repeater on Helix Water’s Calavo tank, located near Mt. Helix.
“When public agencies work together to improve the lives of our citizens, everyone benefits,” said Helix Board President Mark Gracyk. “We are delighted with the outcome and are very proud to participate in making East County a safer place to live.”
Heartland’s goal is to provide its customers with the highest quality of public safety communications services. Heartland provides public safety communication services to 13 fire agencies throughout East San Diego County. It uses a universal radio system – known as a VHF radio – to communicate with fire agencies and first responders.

Though reliable, the hilly terrain of East County can interfere with VHF radio communications. As part of its effort to improve communication in El Cajon and Spring Valley, it needed a suitable location to install a radio repeater between the two communities. The Calavo storage tank was ideally positioned to play home to the new repeater. Heartland approached Helix to work out an agreement.
“Heartland Communications Facility Authority knows the needs of our local emergency communication infrastructure,” said Dan McMillian, Helix Water District board member. “When Heartland approached Helix, our board saw this as an opportunity for our two agencies to work together for the benefit of the communities that we serve.”
“The addition of a radio repeater on the Calavo Drive water tank will allow firefighters from throughout the state who respond to the East County to communicate with each other and the dispatch center using this repeater,” said Carlos Castillo, Director of Heartland Communications. “Communications are an integral part of the firefighting effort in suppressing wildland fires, and firefighter safety relies on an effective communication infrastructure.”

Construction started in March 2020 and was completed in June 2020. Improvements at the Calavo site included installing a new radio repeater and a four-foot antenna at the top of the tank. As part of the project, San Diego Gas and Electric installed a new electric service and meter at the site so Heartland’s equipment can operate independently from Helix’s pumps and monitoring equipment.
“Heartland Communications would like to thank Helix Water District for allowing us to install our VHF repeater on their water tank,” said Castillo. “This collaboration between Helix and Heartland is a win-win for the fire service and the community. It will provide the critical communications infrastructure needed to enhance public safety.”
The Heartland Communication Facility Authority provides emergency communication services for its member agencies, which include Alpine Fire, Bonita Fire, San Miguel Fire, City of El Cajon, City of La Mesa, City of Lemon Grove, Lakeside Fire, City of Santee, Barona Fire and Viejas Fire.
The Helix Water District treats and delivers water to 277,000 people in La Mesa, El Cajon, Lemon Grove, and parts of Spring Valley, Lakeside, and unincorporated San Diego County.
A magnitude 6.9 earthquake on San Diego’s Rose Canyon Fault could damage 100,000 residences, cause widespread road and bridge failures, and make parts of Mission Bay sink about a foot, according to the most detailed disaster scenario ever done on the region.
Such a temblor could also cut gas and water service between La Jolla and the Silver Strand for months, collapse key municipal buildings, and close the San Diego-Coronado Bridge, says a report by the San Diego chapter of the Earthquake Engineering Research Institute. Parts of the fault would rupture the Earth’s surface and shift the landscape 6 to 7 feet, damaging streets so badly it would make it hard for police, firefighters and paramedics to get around.
To protect its employees, members of the public, and the environment from any accidental chemical releases or exposure, the Vallecitos Water District has established its own internal Hazardous Materials Response Team or HAZMAT team.
To protect its employees, members of the public, and the environment from any accidental chemical releases or exposure, the Vallecitos Water District has established its own internal Hazardous Materials Response Team or HAZMAT team. Maintaining its own internal team allows a 24-hour response capability.
Common hazardous chemicals play vital roles in the water and wastewater industry for disinfection and odor control. They are also used in fueling and maintaining agency vehicles, generators, pumps, and motors.
A HAZMAT team is an organized group of professionals who receive special training to handle hazardous materials or dangerous goods. A HAZMAT team responds to oil, chemical and other liquid spills, industrial and military explosions and accidents during transportation, and similar incidents.

The Vallecitos Water District HAZMAT team consists of 20 members from different departments. They complete U.S. Occupational Safety and Health Administration Hazardous Waste Operations and Emergency Response training, which provides a set of guidelines regulating hazardous water waste operations and emergency services in the U.S.
When an emergency call requires HAZMAT team response, individual members move from their regular job assignments to the HAZMAT Response Trailer. The team then mobilizes to the site of the emergency.

“It’s a great honor just knowing we’re here to protect people in the surrounding areas, to protect the environment, and to know we’re here to jump into action in case there’s an issue,” said Matthew Wiese, senior plant operator at the Meadowlark Treatment Facility. “We’ve trained and we’ve gone through scenarios. Being able to act with confidence, it’s a great thing to be a part of that team.”
Vallecitos Water District HAZMAT team members wear specialized personal protective equipment and clothing to make safe entries into potentially hazardous areas. If a leak or spill of chemicals occurs, the HAZMAT team uses specialized tools and equipment to identify, and stop the release and spread of any contamination as quickly as safely possible.
Team members conduct monthly drills on common scenarios.
“If there was a release of chlorine gas which we use to conduct our wastewater treatment activities, we have specialized equipment and materials to lock down those cylinders so we can stop the release,” said Trisha Woolslayer, risk management supervisor. “We practice on a regular basis so we react quickly if an accidental release were to occur.”
Following each exercise, all team members hold a debriefing to discuss their observations, and how procedures might be improved.
Woolslayer said swifter response times and cost savings offset the investment in training and equipment by the District.
“It allows us to respond quickly, to stop whatever spill it is and protect the environment,” she said. “There are also cost savings. We spend on training and equipment, but it is a small amount compared to having a response contractor on call.”
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.
When residents in De Luz were forced to evacuate about 100 homes during the Rock Fire in July, an emergency generator installed by the Fallbrook Public Utility District proved its value by providing water to help firefighters extinguish the blaze. The generator was installed about a year ago at the Donnil Pump Station at a cost of about $140,000. Since then, several fires have sparked in the hilly backcountry community north of Fallbrook.
