If you’ve ever driven past pipes sticking out of the ground and wondered, “What is that thing?” you aren’t alone. While sitting at a red light one day, Olivenhain Municipal Water District Customer Services Manager John Carnegie glanced at a pipe and realized there were probably members of the public who are unaware of the role key water infrastructure objects in their neighborhoods play in delivering safe, reliable water.
Olivenhain Municipal Water District’s Recycled Water Pipeline Extension 153A was recognized September 10 as a 2020 Project of the Year by the San Diego and Imperial County Chapter of the American Public Works Association at its virtual awards event. The pipeline extension connected the Surf Cup Sports youth soccer fields in San Diego to OMWD’s recycled water distribution system. By allowing Surf Cup to convert the irrigation of 55 acres of grass fields to recycled water, OMWD has reduced potable water demands for irrigation by up to 100 million gallons per year.

“OMWD’s board is honored to receive this award for a collaborative project, which expanded the use of recycled water while protecting the environment,” said OMWD Board Treasurer Larry Watt. “Additionally, state grant funding helped pay for the project, reducing costs for our ratepayers.”
The project involved the installation of 1,600 feet of 8-inch PVC pipeline that required specialized drilling and interagency cooperation to be completed. The pipeline needed to cross the San Dieguito River, causing design, permitting, and construction obstacles. OMWD’s design team used horizontal directional drilling to install the pipeline more than sixty feet below the river bottom.
Horizontal directional drilling reduces not only surface area damage, but also environmental impacts from construction site dust, making it less impactful to nearby habitat and communities than traditional excavation work.
OMWD worked with the California Department of Fish and Wildlife on a streambed alteration agreement to ensure the protection of fish and wildlife habitat. OMWD also worked with the U.S. Fish and Wildlife Service to protect nesting birds such as the federally listed clapper rail and barn owl.
By OMWD taking proactive steps, such as daily biological sweeps of the project and inspections of the trenchless process, there was no adverse impact to habitat or species in the project area.
Interagency cooperation was also required for the project. The property is served water by Santa Fe Irrigation District and owned by the City of San Diego. While SFID did not have nearby recycled water infrastructure, it wanted to provide Surf Cup fields with a drought-resilient water supply. The OMWD pipeline project meets that need. The San Diego City Council approved a permanent utility easement allowing crews to access the property.
California’s Department of Water Resources awarded $202,300 for the project in Proposition 84 funding, which is administered by water wholesaler San Diego County Water Authority through the Integrated Regional Water Management program. The San Diego IRWM Program supports collaborative water management to increase regional self-reliance throughout California.
APWA is a professional association of public works agencies, private companies, and individuals dedicated to promoting public awareness through education, advocacy, and the exchange of knowledge. The APWA San Diego and Imperial County chapter annually recognizes the best public works projects and professionals in San Diego and Imperial Counties. The Project of the Year award is also intended to highlight the collaboration and cooperation between public and private agencies, contractors, and consultants, to complete public works projects.
Encinitas, Calif. — Olivenhain Municipal Water District’s Board of Directors voted unanimously at its August meeting not to raise water capacity fees in Fiscal Year 2021. After a comprehensive review, the board determined that current fees adequately cover OMWD’s planned capital expenditures through June 30, 2021.
Capacity fees are one-time charges to new development connecting to OMWD’s water system. Capacity fees are collected to fund necessary system expansion, replacement, and improvement projects to provide current and future ratepayers with a safe, reliable water supply.
Earlier this month Olivenhain Municipal Water District announced they began supplying locally produced recycled water to the Seagate Village Homeowner Association in Encinitas.
The project is a collaboration between OMWD and San Elijo Joint Powers Authority since 2014 to bring recycled water to the Village Park neighborhood. San Elijo Water Campus, located in Cardiff-by-the-Sea, uses a combination of sand filtration, microfiltration, and reverse osmosis to produce high-quality water for irrigation and industrial uses.
The City of Encinitas and the Olivenhain Municipal Water District are working together on a project that keeps water supply and traffic flowing.
To prevent water main breaks and ensure reliable service to its customers, Olivenhain Municipal Water District is proactive in its repair and replacement of aging water infrastructure.

In early April, OMWD began construction to replace aging water infrastructure along El Camino Real in Encinitas. The work marks the start of the El Camino Real Potable Water Pipeline Replacement and Green Bike Lane Striping Project. Construction is expected to last about one year.
During the project, OMWD will replace approximately 4,700 linear feet of existing 12-inch diameter potable water pipeline along North El Camino Real from Encinitas Boulevard to Garden View Road and approximately 650 linear feet of existing 12-inch diameter pipeline between Via Molena and Mountain Vista Drive. Water service lines and fire hydrant laterals served by the existing pipelines will also be replaced.
The two pipelines being replaced were originally installed in 1961 and 1974, and are approaching the end of their lifespan.
The American Society of Civil Engineers estimates that there more than 240,000 water main breaks in the United States every year. The main breaks waste over two trillion gallons of treated drinking water, but also interrupt water service to homes and businesses, and require costly and disruptive emergency repairs.
After OMWD’s pipeline work is complete, the City of Encinitas will implement traffic calming measures and improve safety and mobility for bicyclists along North El Camino Real from Encinitas Boulevard to Leucadia Boulevard by restriping and narrowing travel lanes.
The work will include adding bollards to existing bike lanes, applying green color to some areas on the bike lanes, and additional signage and pavement markings will also be installed.
OMWD will implement the lane restriping portion of the project on behalf of the City of Encinitas, which will take place concurrently with the pipeline replacement project.
The two agencies have combined efforts to maximize operational efficiencies and to reduce impacts to area residents and businesses.
Originally, OMWD’s project was scheduled to begin in 2021. Encinitas Council Member Joe Mosca and OMWD Board Treasurer Larry Watt identified the opportunity to streamline the two projects, maximizing efficiencies and minimizing impacts to the community. Because the City’s project had a deadline for grant funding, the two agencies ultimately decided it would be more efficient to advance the timeline of OMWD’s project.
“El Camino Real is a major thoroughfare and any work done there needs to be executed with maximum care and efficiency in mind to keep impacts to businesses and residents low,” said Larry Watt, OMWD board treasurer. “By coordinating the pipeline replacement project with the City’s project, the community can enjoy a continued safe and reliable water supply and improved road safety with the least disturbance possible.”
“The City of Encinitas is continuing its track record of environmental responsibility by making our streets safer for bicyclists and pedestrians through the Active Transportation Enhancing Project,” said Encinitas Councilmember Joe Mosca. “The City’s partnership with OMWD on this project highlights the benefits of collaboration between neighboring public agencies on critical infrastructure projects.”

In addition to the partnership, OMWD has taken steps to minimize the impact of the project on residents and businesses along North El Camino Real. A City-approved traffic management plan will be implemented during construction. All work was originally scheduled to be completed at night to minimize traffic impacts.
As a result of the reduced traffic from the statewide stay-at-home order, the agencies adapted hours in April to 7:30 a.m. to 6 p.m., Monday through Friday. The change allows work to be completed more efficiently and safely.
Olivenhain will work closely with the City to monitor the project’s impact on traffic on a week-by-week basis and modify the schedule as needed along with project contractor Teichert Energy and Utilities Group while still maintaining efficient operations.
OMWD anticipates a single shutdown of water service for most businesses/residences, kept as short as possible. Project updates are posted on its website. Email questions to or call 760-632-4235.
