San Diego County residents joined Americans across the country marking Thursday, October 21 as “Imagine A Day Without Water.” The nationwide awareness campaign offered opportunities to learn about our nation’s water systems and the hard work that goes into ensuring a day without water doesn’t become a reality for their community.
The day-long event is sponsored by the U.S. Water Alliance, the only national nonprofit organization with a diverse membership base representing the range of water champions, including water utilities, public officials, the business community, environmental organizations, community leaders, policy organizations, and researchers.
The Vallecitos Water District partnered with the City of San Marcos to promote Thursday’s awareness efforts among its residents. San Marcos Mayor Rebecca Jones starred in a video produced by VWD to highlight its water infrastructure investments. In the video, Mayor Jones encourages residents to conserve water. The San Marcos City Council officially proclaimed October 21, 2021 as “Imagine a Day Without Water.”
California Governor Gavin Newsom extended the state’s drought emergency on October 19, appealing to all Californians to do more to conserve water in the face of one of the state’s most severe droughts on record. The declaration added eight remaining counties, including San Diego County, not under the original declaration made in July.
In the United States, aging infrastructure, intensified weather events, and a lack of investment have kept more than two million residents from accessing safe and reliable water and wastewater services. Member agencies, including the Vallecitos Water District along with the San Diego County Water Authority, continue to develop and maintain safe, reliable water supplies and critical infrastructure through strategic planning, long-term investments, and state-of-the-art technologies.

The San Marcos Interceptor Replacement Project remains on schedule, with Phases 1 and 1A completed according to the Vallecitos Water District. The project replaces the District’s 1960s era 21-inch diameter sewer interceptor with more than 12,000-feet of 42-inch diameter sewer pipeline between Twin Oaks Valley Road and Pacific Street.
The Interceptor is a large trunk sewer pipeline receiving and conveying wastewater by gravity to the Encina Wastewater Authority. In Phases 1 and 1A of the project between 2002 and 2014, portions behind the Creekside Marketplace from State Route 78 to Grand Avenue, from Twin Oaks Valley Road to east of Johnston Lane, from Grand Avenue to Via Vera Cruz, and east of Johnson Lane to the south side of State Route 78 were completed.
Phase 2 will complete the remaining 3,400-feet of the westernmost project corridor extending from Via Vera Cruz to Pacific Street. The project budget is $8.5 million. The completion of Phase 2 of the Interceptor project has been in the works for more than 30 years, with the project exchanging numerous hands in planning, design, and construction.
“This is a milestone project for the District both in size and significance,” said Ryan Morgan, capital facilities senior engineer.

The project used state-of-the-art trenchless technology to install a 115-ft long tunnel under an existing concrete culvert under the Pacific Street and San Marcos Boulevard intersection. The 42-inch diameter fiberglass reinforced plastic Interceptor sewer was installed inside a 60-inch diameter steel casing pipe.
Using a process known as “microtunneling,” contractor TC Construction and sub-consultant JW Fowler used a MicroTunnel Boring Machine (MTBM) inside an excavation in the eastbound lanes of San Marcos Boulevard and be received in a smaller excavation in the westbound lanes of San Marcos Boulevard at Pacific Street.
The MTBM is larger than 60-inches in diameter to be large enough to bore through native soils, rock, and backfill along the Interceptor alignment. The new tunnel’s wall is pressurized internally using hydraulic fluids before the steel casing is permanently installed. The MTBM is remote-controlled by an operator on the surface and is laser-guided to ensure it stays within the designed horizontal and vertical alignment (line and grade).
The MTBM’s high level of accuracy makes it especially useful when a project needs to avoid conflicts with existing underground utility lines, including a 16-inch diameter high-pressure San Diego Gas & Electric gas line in this project. The microtunnel installation was a 24-hour, 7-day-a-week process.
The microtunnel allowed the District to “thread the needle,” and the tunnel was completed in under a week (plus setup). There was no damage to any of the existing utilities in San Marcos Boulevard, and traffic impacts were minimized.

The Interceptor project required biological monitors and archeological monitors for work adjacent to San Marcos Creek or predetermined environmental sensitive areas. Special mitigation measures and biological monitoring were required for construction during bird nesting season between February 15 and September 15. Additionally, tribal paleological monitors from Native American tribes of significance in the area were represented during excavation work in the creek.
The final leg of the project will begin in the easements adjacent to the creek between Via Vera Cruz and McMahr. Construction completion is expected in June 2021.
This replacement project was originally identified in the District’s 1991 Master Plan and has been phased to be completed prior to City of San Marcos development of the Creek District.

Vallecitos Water District crews sprang into action to repair and rehabilitate a manhole in danger of failing, successfully preventing a spill, which could have resulted in significant environmental damage.
Located just off Palomar Airport Road in a shared 30-foot easement with the Buena Sanitation District in Carlsbad, the manhole is part of a 30-inch outfall providing a main sewage drain for the City of San Marcos. The line feeds directly into the Encinas Wastewater Treatment plant a half-mile from the project site.
Vallecitos Water District crews sprang into action to repair and rehabilitate a manhole in danger of failing, successfully preventing a spill, which could have resulted in significant environmental damage.
Located just off Palomar Airport Road in a shared 30-foot easement with the Buena Sanitation District in Carlsbad, the manhole is part of a 30-inch outfall providing a main sewage drain for the City of San Marcos. The line feeds directly into the Encina Wastewater Treatment plant a half-mile from the project site.
Originally constructed in the 1980s, turbulence generated by a hard right-turn along the sewer easement creates hydrogen sulfide gases. These gases corrode concrete and weakened the manhole over the years. Flooding also occurs in the area and allows rainfall to infiltrate the manhole.
Vallecitos Water District staff became concerned the structure could fail. The result would be a major sewage spill affecting the nearby Encinas Creek Habitat Conservation Area, ultimately spilling into the Pacific Ocean a mile downstream. The Habitat Conservation Area is owned by the Center for Natural Lands Management, which supports its management through an endowment.
The Encinas Creek HCA is also part of the City of Carlsbad’s habitat management preserve. It includes riparian habitat and is known to be home to state and federally protected species. The Center for Natural Lands Management works to protect the property from trespassing, nonnative invasive plant and animal species, and other issues.
The District determined emergency repairs were required. Although the Vallecitos Water District has proper easement rights to access, operate, and maintain the pipeline, the agency must avoid any impact to the existing habitat while repairing the manhole. This required some creativity by the work crews.

The District kept all construction activities within its existing easement to avoid any impacts to existing riparian vegetation. Crews constructed a temporary bridge over an existing stream obstructing access to the manhole. The bridge installation was designed to be temporary, and not affect the existing stream with footings or other supports. Constructing the bridge for access turned out to be the most complex part of the repair project.
District crews working with a contractor team took advantage of the lower sewage flow during the early morning hours, starting work at 3 a.m. to get as low into the waterline as possible. Repairs like this take advantage of the low flows to keep critically important sewer systems in operation.
Instead of replacing the manhole, the District used a polymer concrete replacement product to build a new manhole within the old manhole. As a result, no excavation was needed. Unlike regular concrete, the new material is corrosion-proof and should provide District customers in San Marcos with many years of reliable service while protecting the environment.
Mission Hills High School student Jordan Chan of San Marcos won third-place in the statewide 2020 California Special Districts Association video scholarship competition. The “Districts Make The Difference” contest is designed to promote public awareness and understanding of the special districts providing communities with essential services like water, sanitation, healthcare, fire protection, and parks.
Chan received his $500 scholarship prize at the February Vallecitos Water District board meeting. He received recognition from state legislators and CSDA representatives. Chan was honored with a proclamation from San Marcos Mayor Rebecca Jones, and certificates of recognition from the offices of State Senator Brian Jones and State Assemblywoman Marie Waldron.

“Jordan is clearly a talented young Californian whose academic career the California Special Districts Association is proud to support,” said Kyle Packham, CSDA advocacy and public affairs director. “Jordan’s video will raise awareness and understanding of the special districts serving our community and encourage other students like him to become more civically engaged.”
Chan’s video showcased his skill and creativity by using a Wild West time travel theme to illustrate the importance and variety of special districts serving San Marcos and other communities throughout California, which includes the Vallecitos Water District.
CSDA’s statewide “Districts Make the Difference” video contest encourages high school and college students to learn about the local governments serving their classmates and families. Students were challenged to create a 60 to 90-second video highlighting how special districts have enhanced the lives of Californians through the delivery of local services and infrastructure to their community.
Students throughout California participated in the 2020 contest. Entries were scored by CSDA officials based on four criteria: accuracy and effectiveness, creativity and originality, production quality, and entertainment value. The five videos with the highest overall scores competed for public votes at the Districts Make The Difference website, where all the winning videos are posted.
In addition to Chan’s third-place win, Erubiel Monterosa of Bakersfield won first place, and Maryam Aslam of Sacramento placed second.
“Districts Make the Difference” is a public outreach campaign sponsored by CSDA to increase public awareness and understanding of special districts and promote civic engagement.
The Vallecitos Water District is moving beyond traditional bill mailers and tri-fold brochures to communicate with its customers in a more effective and dynamic way by using video.
Vallecitos Board President Hal Martin conceived the idea to create “Work We Do” videos to help customers see and understand first hand the complex work Vallecitos water professionals perform to ensure reliable water and wastewater services. Viewers see and hear from the workers in the field as they complete tasks such as replacing outdated equipment or using smoke testing to detect sewer leaks and protect the environment.
“I’ve seen the quality of staff videos and I realized it was the perfect way to show our customers exactly what we do,” said Martin of the series and the initiative.
Watching crews in action providing the community with reliable drinking water and wastewater services, protecting the environment, and developing the next generation of water workers, makes customers better informed citizens about the area’s vital infrastructure in a transparent way.
The video series also includes helpful information such as how to read water meters.

“We’re working to change our Public Information Department and keep up with current technology,” said Chris Robbins, Vallecitos public information and conservation supervisor.
Robbins said the goal is to feature each department within the district and focus on topics that lend themselves to visual communication. Videos run three minutes or less to keep the audience engaged.
Finished videos are posted to the district website, YouTube, Facebook and Twitter. The videos can also be seen on the City of San Marcos news channel, San Marcos TV. Videos are also shared through water industry news websites such as Water News Network.
Alicia Yerman, a Vallecitos public information representative, shoots and edits the video series. She schedules time to join crews at work when performing a specific task. She also plays talent scout, finding a knowledgeable employee who can describe the work on camera.
Not all staff want to talk, but Yerman is able to coax at least one Vallecitos staff member to be the ‘on camera talent,’ and she also has a knack for bringing out their best. She finds ways to make staff more comfortable being on camera—either by asking questions or placing staff members in comfortable settings.
Yerman and Public Information Representative Lisa Urabe were recently certified as drone pilots. Future videos will feature district work from a bird’s eye point of view.
