El Camino Real Potable Water Pipeline Replacement and Green Bike Lane Striping Project

The American Society of Civil Engineers estimates that there are over 240,000 water main breaks in the United States every year. Not only do these main breaks waste over two trillion gallons of treated drinking water, but they interrupt water service to homes and businesses, and require costly and disruptive emergency repairs.

To prevent water main breaks and ensure reliable service to your property, Olivenhain Municipal Water District is proactive in its repair and replacement of aging water infrastructure.

Two aging distribution mains located beneath El Camino Real were originally installed in 1961 and 1974, and are approaching the end of their lifespan. OMWD plans to replace these pipelines in the coming months, with construction anticipated to begin this winter.

The project will replace approximately 4,700 linear feet of existing 12-inch diameter water pipeline in North El Camino Real from Encinitas Boulevard to Garden View Road and approximately 650 linear feet of existing 12-inch diameter pipeline in North El Camino Real between Via Molena and Mountain Vista Drive. Water service and fire hydrant laterals served by the existing pipelines will also be replaced.

In addition to the pipeline replacement, the City of Encinitas will implement traffic calming measures along El Camino Real from Encinitas Boulevard to Leucadia Boulevard. Measures will include restriping and narrowing current travel lanes, and will improve safety and mobility for bicyclists by adding buffers to existing bike lanes. Buffered areas will be delineated with traffic reflective and re-erectable bollards. Green color will be used at certain areas on the bike lanes to further notify the users of the potential areas of conflict between bicycles and motor vehicles. Additional signage and pavement markings will also be installed as needed.

On behalf of the City of Encinitas, OMWD will implement the lane restriping portion of the project which will take place concurrently with the pipeline replacement project. The interagency cooperation on this effort will minimize expenses and the duration of traffic impacts to El Camino Real.

OMWD will be taking several steps to reduce the impact of the project to residents and businesses along North El Camino Real. Areas of focus will include:

  • Traffic control
  • Access to businesses and residences
  • Pedestrian access
  • Continuity of water service
  • Noise and light during night construction
  • Access for services such as:
    • Deliveries
    • Mass transit
    • Emergency vehicles

A city-approved traffic management plan will be implemented during construction and most work will be done at night to minimize traffic impacts. OMWD anticipates there will only be one shutdown of water service for most businesses/residences, the duration of which will be kept as short as possible.

Manchester Avenue Recycled Water Pipeline Project

To expand the availability of OMWD’s recycled water, OMWD is planning to connect to San Elijo Joint Powers Authority’s recycled water transmission pipeline near Interstate 5 and Via Poco. From that connection, OMWD will construct a new recycled water pipeline along Manchester Avenue.

The Manchester Avenue Recycled Water Pipeline Project involves the construction of approximately 1.4 miles of six-inch diameter recycled water pipeline. The new pipeline will expand recycled water service to the corridor along Manchester Avenue and South El Camino Real from Interstate 5 freeway to Tennis Club Drive.

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.

The pipeline will deliver recycled water supplied from San Elijo Joint Powers Authority’s San Elijo Water Reclamation Facility. The Project is part of the larger North San Diego Water Reuse Coalition’s Regional Recycled Water Project, which coordinates resources across the jurisdictional lines of nine North County agencies.

This project has been awarded $600,000 in Proposition 84 grant funding for a portion of the project. An additional $750,000 in grant funds from Proposition 1 has been secured for the remainder of the pipeline. Construction is anticipated to begin in summer 2020 and will take approximately seven months to complete.

 OMWD staff presented project details, as well as the benefits and requirements of using recycled water for landscape irrigation purposes, at a citizen’s participation meeting on January 7.

If you have questions about the project, please contact our Engineering Department or call 760-632-4235.

Environmental Public Comment Period & Public Hearing

OMWD has prepared an Initial Study/Environmental Checklist and Mitigated Negative Declaration that addresses the potential environmental impacts of the Manchester Recycled Water Pipeline Project in accordance with the California Environmental Quality Act. The analysis in the Initial Study supports the conclusion that with the inclusion of mitigation measures, the project would not result in significant environmental impacts.

On November 13, 2019, OMWD’s Board of Directors approved the release of the IS/MND document for public review and comment. The comment period ended January 15, 2020.

A public hearing was held in OMWD’s boardroom on Wednesday, January 15, 2020 at 5:30 p.m. to receive comments on the IS/MND for the Project.

Rancho Santa Fe Road Pipeline Condition Assessment

To ensure water supply reliability, crews initiated a pipeline condition assessment of a potable water pipeline under Rancho Santa Fe Road in Carlsbad in January. Pipeline Inspection and Condition Analysis Corporation’s “See Snake” technology is being utilized for this project. The results of the condition assessment and data analysis will allow OMWD to make informed decisions for pipeline upgrades, renewal, or continued maintenance.

OMWD has over 500 miles of pipeline in its 48-square-mile service area, which are subject to extreme environments, including high pressure and shifting or corrosive soil. Unmonitored pipelines that silently reach the end of their useful life can create problems in the community.
