Manchester Avenue Pipeline Replacement Project Underway in Encinitas

/in , /by

Work is progressing toward completion on the first of two pipeline replacement projects in Encinitas by Olivenhain Municipal Water District.

Replacement of an existing drinking water pipeline is wrapping up at Rancho Santa Fe Road and Encinitas Boulevard, with completion expected in early 2022. The original pipeline was installed in 1961 and was approaching the end of its lifespan. Proactively replacing aging water pipelines prevents leaks and avoids emergency shutdowns.

“Water main breaks can waste millions of gallons of treated water while requiring costly emergency repairs,” said Bob Topolovac, Olivenhain Municipal Water District Board director. “That is why this project is critical in ensuring safe and reliable water delivery to our customers.”

Pipelines being replaced include:

  • Approximately 1,900 linear feet of 12-inch pipeline in Manchester Avenue from Colony Terrace north to Encinitas Boulevard
  • Approximately 450 linear feet of 12-inch pipeline in Encinitas Boulevard west of Rancho Santa Fe Road
  • Approximately 500 linear feet of 12-inch pipeline in Rancho Santa Fe Road north of Encinitas Boulevard
  • Approximately 850 linear feet of eight-inch pipeline in South Rancho Santa Fe Road

Recycled water pipeline helps reduce drinking water demand

In early 2022, the water district will begin its second project, installing 1.4 miles of six-inch recycled water pipeline under Manchester Avenue and S. El Camino Real. When completed, recycled water will be connected to the San Elijo Joint Powers Authority’s Recycled Water Pipeline and North Plant. It will be part of the North San Diego Water Reuse Coalition’s Regional Recycled Water Project.

Homeowner associations, schools, and businesses along the project alignment that are currently using potable water for landscape irrigation will be able to take advantage of this lower-cost, drought-resistant local source of water for irrigation. These new customers connecting to this pipeline will reduce the need for 10 million gallons of potable drinking water per year.

Multiagency coordination on pipeline replacement

The pipeline will be installed along Manchester Avenue between Via Poco and Tennis Club Drive. Since Caltrans is working at I-5 and Via Poco, the water district is coordinating its work with Caltrans to minimize traffic impacts to the Manchester Avenue Corridor.

Construction is expected to take nine months. The project received approximately $1.75 million in state and federal grant funding, reducing costs for its ratepayers.

Prior to construction in summer 2021, the Olivenhain Municipal Water District hosted a virtual neighborhood meeting. Staff provided project details and steps that will be taken to reduce impacts to the community and sought input from members of the public. Video of the meeting can be viewed here. (NOTE: some of the scheduling information has changed).

The project is expected to be completed in early 2023. Project updates can be found at www.olivenhain.com/projects. For questions or concerns, email or call 760-632-4235.

Biden Administration Moves to Scrap Cadiz Water Pipeline Right-Of-Way Permit, Cleared by Trump

/in , , /by /Los Angeles Timesby Alex Wigglesworth, Ian James

Federal authorities have moved to reverse a Trump administration decision that cleared the way for Cadiz Inc. to pipe water across public land in the California desert.

The request filed in federal court Friday, which must still be granted, could deal a blow to the company’s decades-long effort to pump groundwater from beneath its desert property 200 miles east of Los Angeles and sell it to urban Southern California. The project is fiercely opposed by conservationists, who say it will dry up desert springs and seeps relied upon by Indigenous tribes and rare wildlife. Cadiz insists its plans won’t harm springs in the area.

The new infrastructure law signed by President Biden includes almost $50 billion to protect communities against climate change, the largest such investment in United States history and a recognition that the effects of warming are outpacing America’s ability to cope.

Mr. Biden has insisted that at least 40 percent of the benefits of federal climate spending will reach underserved places, which tend to be low-income, rural, communities of color, or some combination of the three.

City and Caltrans crews remained at work in downtown Tuesday, cleaning up the mess after two water main breaks on Sunday closed freeway on-ramps and flooded businesses.

The first break came from a 76-year-old cast iron pipe near 11th and A street, which flooded local businesses and snarled traffic. Some time later, a 62-year-old concrete steel cylinder pipe failed near balboa park.

Infrastructure Bill Seen as Way to Pay Farmers to Cut Water Use

/in , /by /Bloomberg Lawby Tripp Baltz

Four states in the drought-wracked West considering whether to pay farmers to cut their water use see federal infrastructure legislation as a possible revenue source.

The $550 billion bipartisan legislation approved in the Senate includes $25 million for the four states—Colorado, New Mexico, Utah, and Wyoming.

“There’s that bucket, and a lot of other buckets, in the federal infrastructure bill that could come into play for drought contingency planning implementation,” said Amy Ostdiek, interstate and federal manager in the Colorado Department of Natural Resources.

Joint Project By Olivenhain MWD and City of Encinitas Reaches Final Phase

/in , /by

The El Camino Real Potable Water Pipeline Replacement and Green Bike Lane Striping Project has reached its final stage. After the Olivenhain Municipal Water District Board approved filing of a notice of completion for the pipeline portion of the project, the City of Encinitas will finish restoring the street and complete new bike lane striping.

The original pipelines were installed in 1961 and 1974 and fast approaching the end of their lifespan. OMWD replaced 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 were also replaced.

The pipeline replacement will reduce water loss and prevent emergency shutdowns due to leaks. This is vitally important for water conservation and to ensure water supply reliability for businesses and residents, more important than ever due to drought conditions in the region.

“Proactive maintenance is a big part of what we do,” said Olivenhain Municipal Water District Board President Larry Watt. “Replacing aging infrastructure before it breaks helps to avoid emergencies, which are more costly and more impactful to customers.”

Coordination minimizes community inconvenience

To mitigate the impact to the surrounding community, OMWD coordinated with the City of Encinitas on its green bike lane project along the same route. The District implemented the lane restriping portion of the project on behalf of the City of Encinitas concurrently with the pipeline replacement project as an efficiency measure.

As a result, the two agencies combined what would normally be two separate, unrelated infrastructure improvement projects into a single effort to improve operational efficiency and reduce the temporary inconvenience of disruptions to area residents and businesses.

The bike lane will provide traffic calming measures, including improvements to safety and mobility for bicyclists along North El Camino Real from Encinitas Boulevard to Leucadia Boulevard by restriping and narrowing travel lanes. In addition, green-colored striping will augment some areas on the bike lanes and new signage and pavement markings will be installed.

“It was very important to us from the outset of the project to mitigate its impacts to the community, while also keeping costs down,” said Watt. “To that end, the partnership with the City of Encinitas was critical. They coordinated closely with us every step of the way.”

At the start of the project, the City of Encinitas requested that work be done at night to further reduce traffic impacts. Capitalizing on the reduced traffic as a result of the statewide stay-at-home order, OMWD was able to shift construction to the daytime for a portion of the project. Working during the day is more efficient and safer than night work, and minimized noise impacts to the surrounding neighbors. However, as traffic returned to normal levels, the City shifted work hours back to overnight.

The final work effort will include buffered bike lanes on the east and west, and fully restoring three lanes of traffic. Work is anticipated to occur through early December. Traffic controls will be in place during the day and at night with the most significant work occurring at night. Residents and businesses should anticipate lane closures and consider alternative transportation routes.

Opinion: Priced Out and Shut Off: Tackling Water Affordability

/in , , /by /The Hillby Michael Mcafee and Susana De Anda

Right now, Congress is debating needed investments in our water system decades in the making. While the Senate’s compromise bill passed earlier this month includes billions for lead pipe replacement and helping communities prepare for future drought and floods, the bill falls short of ensuring all families can turn their tap on and access safe, affordable water.

Infrastructure spending isn’t enough. We must pair new water spending with bill assistance to ensure the water flowing through our upgraded pipes serves all households in America. This is especially true as the country faces another rise in COVID-19 cases.
