Recycled Water Pipeline Projects Ensure Reliable Water Supplies for Olivenhain Municipal Water District

/in , /by

Olivenhain Municipal Water District is beginning construction on new recycled water pipelines in Encinitas. The pipelines are part of a larger expansion of OMWD’s recycled water distribution system that will result in the savings of more than 12.5 million gallons of imported drinking water each year.

This phase of the project involves installing pipelines on Summerhill Drive and Village Center Drive in Encinitas. Work is scheduled to take place Monday through Friday, 8:30 a.m. to 3:30 p.m. Additionally, restricted work hours of 9 a.m. to 2 p.m., Monday through Thursday, and 9 a.m. to noon on Friday, will be in effect for any work directly impacting Diegueño Middle School.

Other project phases involved the construction of recycled water pipelines around Park Dale Lane and Gatepost Road in Encinitas, which are now complete, and along Calle Barcelona in Carlsbad, on which work continues. This project is anticipated to be completed in spring 2025. No impacts to customers’ drinking water supplies are anticipated.

Minimizing Traffic Disruptions for Customers

OMWD is coordinating with the cities of Carlsbad and Encinitas on a traffic management plan to minimize traffic disruptions for residents and businesses during construction. Learn more in the video presentation below.

OMWD successfully secured approximately $900,000 in grant funding to make this project cost-effective for ratepayers. Specifically, both the US Bureau of Reclamation and the California Department of Water Resources are contributing grant funds to offset project costs.

OMWD receives 100 percent of its drinking water supply from the Sacramento-San Joaquin Delta and the Colorado River. These sources have become unreliable due to droughts and overuse.

Recycled water is locally produced, disinfected wastewater used for irrigation. It is a drought-resilient supply and costs less than potable water. In addition, using recycled water reduces the amount of treated wastewater discharged to the ocean and reduces our dependence on imported water from faraway sources.

OMWD has identified opportunities in Encinitas and Carlsbad to connect more customers to its recycled water distribution system. The completion of the pipeline extensions will result in the conversion of 28 water meters from potable to recycled water, saving more than 12.5 million gallons of imported drinking water every year.

OMWD produces up to two million gallons of recycled water daily at its 4S Ranch Water Reclamation Facility. Additionally, OMWD is the lead agency of the North San Diego Water Reuse Coalition, a group of nine North County agencies that coordinate across jurisdictional boundaries to expand the reach of the recycled water.

As a result, OMWD now serves up to 15 percent of its overall demand from recycled water and continues to identify additional ways to make recycled water available to eligible customers.

New Escondido Water Reuse Plant Supports Area Farmers

/in , /by

The City of Escondido achieved an important milestone in its efforts to create a high-quality alternative water source to support its local agricultural growers in August.

The city and its partners, including the Filanc Brown and Caldwell (FBC) Joint Venture, dedicated the newly completed water reuse treatment plant at an August 28 event. The AgX Membrane Filtration Reverse Osmosis Facility for Agriculture (MFRO Facility) is a first-of-its-kind facility producing water for agricultural use in California.

The new $65 million facility completed construction in November 2023.

Lowering costs, increasing water supply resilience

The AgX MFRO Facility takes water redirected from an ocean outfall, which was reaching capacity and would have cost hundreds of millions of dollars to upsize. Water is now redirected to the MFRO Facility and treated for beneficial reuse by producing water with salinity (salt) levels ideal for agriculture, such as avocado growers.

Farmers benefit from paying lower water rates. With agricultural water use shifted to this new supply, potable water the farmers previously used is now available for other users, increasing local water resiliency.

This project is a rare win-win water solution for augmenting supply while alleviating demand. In an era of water scarcity, it provides a sustainable, local supply and a cost-effective alternative to potable water.

“This is an important milestone for Escondido’s recycled water system,” said Angela Morrow, City of Escondido Director of Utilities. “The MFRO Facility will provide a reliable, affordable, and high-quality water supply to our agricultural community for generations to come while beneficially reusing wastewater and reducing our reliance on imported water.”

Escondido water reuse project funded through multiple agreements

Water Authority Welcomes MWD Chair to Discuss Regional Water Future

/in , , , /by

On Thursday, Metropolitan Water District of Southern California (MWD) Chairman Adán Ortega and Interim General Manager Deven Upadhyay addressed collaboration between two of the largest wholesale water agencies in Southern California in light of MWD’s major long-term planning effort. This process aims to chart a course for meeting Southern California’s water resource management needs while rising to the challenges of a changing climate and maintaining its financial sustainability.

Speaking to the Board of the San Diego County Water Authority, Ortega praised the work of Water Authority Board Chair Mel Katz, Vice Chair Nick Serrano and General Manager Dan Denham during an era of change at both agencies.

“Through your leadership, barriers between our member agencies are coming down opening new possibilities for greater interdependence in our region that can result in greater reliability, value for our residents, and fiscal health for the entire water supply chain,” Ortega said.

Members of the Metropolitan Water District join the August 2024 SDCWA Board meeting for a robust discussion.

This spring, Katz and Denham spoke to the MWD Board about growing the agencies’ relationship based on water security, affordability and mutual benefits.

Ortega touched on similar themes regarding MWD’s ongoing effort to prepare for a changing climate over the next century via its Climate Adaptation Master Plan for Water effort. MWD is trying to chart a course forward with its 26 member agencies that meets the needs of the region while keeping water affordable all in the face of uncertainties caused by the changing climate. Through this process, MWD will consider potential multi-billion-dollar supply projects.

Ortega said the work of the San Diego region’s delegates to the MWD Board have been crucial for helping to chart Southern California’s water future. He thanked Director Tim Smith for leading MWD’s Finance and Asset Management Committee in implementing a two-year budget that was approved without opposition ; Director Marty Miller for his efforts to ensure financial accountability; MWD Secretary Lois Fong-Sakai for establishing a tone of civility at the MWD Board; and MWD Vice Chair Gail Goldberg for her work on MWD’s complex climate adaptation plan.

“Together, during the last two years we have made great progress in steps that are modernizing Metropolitan in the task of climate adaptation,” Ortega said.

East County Advanced Water Program Summer Progress Report

/in /by

Significant work has been completed on the East County Advanced Water Purification Program (East County AWP) since construction began more than two years ago in June 2022. Multiple milestones have been achieved through the first half of 2024, with construction continuing at multiple East County locations through 2025.

The East County Advanced Water Purification Program is an important water project for East San Diego County. When complete, it will deliver a clean, reliable and local water source.

Construction reached a significant milestone in July, completing 58% of the purified water pipeline installation. This 10-mile pipeline will transport purified water from north of Santee Lakes to Lake Jennings.

Elements currently under construction in parts of Santee and Lakeside include:

  • Installing a 10-mile purified water pipeline
  • Constructing wastewater/residual pipelines and pump station upgrades
  • Building water treatment facilities, operations center, laboratory, and public education center

Work underway at Lake Jennings

Crews are working to connect the purified water pipeline to Lake Jennings on the north end of the lake in Half Moon Cove. In April 2024, Helix Water District temporarily lowered Lake Jennings by approximately 23 feet to make this work possible. Helix completed its work on the reservoir’s outlet tower and is refilling the lake.

The lake is expected to be restored to full capacity later this summer. Click here for additional lake updates. Minor work nearby will require occasional, short-term closures of the Flume Trail.

Purified water is expected to start flowing into Lake Jennings in 2026. The water will mix with local and imported water, followed by treatment at the R.M. Levy Water Treatment Plant and then distributed to the community.

Treatment facilities taking shape

Construction of the treatment facilities north of Santee Lakes is progressing, with roughly 80% of the concrete (42,000 cubic yards) poured. Once complete, 52,400 cubic yards of concrete will be used—enough to fill 16 Olympic-sized swimming pools.

The advanced water purification, water recycling and solids handling facilities are being built, as well as an operations center to house the operation controls, laboratory, and education center. The public will be invited to visit the interactive lobby and to tour the facilities once the program goes online.

Wastewater and residual pipelines currently under construction run parallel to each other and are each 3.5 miles long. They will connect the water recycling facility north of Santee Lakes to the pump station near the westbound onramp to Route 52.

The residuals pipeline has been successfully installed under the Carlton Oaks Golf Course and San Diego River using a trenchless construction method called horizontal directional drilling. This method is used instead of digging a conventional open trench, minimizing environmental impacts.

More than 100,000 pounds of pulling force was required for this operation. The installation of the wastewater pipeline running parallel, using the same method, is anticipated by early 2025.

Water from this project will be provided to customers in Padre Dam Municipal Water District, Helix Water District, Lakeside Water District service areas, and the northern portion of the Otay Water District.

Traffic affected in Santee and Lakeside construction zones

Construction has affected traffic in several areas.

In Santee, wastewater pipeline construction is underway on Fanita Parkway near Lake Canyon Road.  When traveling in the area, expect one-way traffic control with delays of up to five minutes. Flaggers are assisting drivers in navigating around the construction zone.

Elsewhere, purified water pipeline construction continues from Park Center Drive, heading west toward Fanita Parkway in Santee. Road paving is complete between Magnolia Avenue and Park Center Drive, and between Cambury Drive and Halberns Boulevard. All of this work has resulted in traffic control with lane closures.

Drivers should plan additional traveling time on Mapleview and Ashwood Streets. Work will continue in this area over the next few weeks. Photo: East County AWP East County Advanced Water

In Lakeside, temporary traffic control with reduced lanes is also in place next to El Capitan High School. Drivers should plan additional traveling time on Mapleview and Ashwood Streets. Work will continue in this area over the next few weeks. On Riverside Drive, construction recently got underway near Rio Camino and is expected to last for the next couple of months.

Purified water pipeline installation along the Channel Road Bridge is complete. Crews will soon shift work locations to State Route 67 and on the west side of the freeway on Mapleview. Pipeline installation under State Route 67 will be achieved using another trenchless construction method called ‘jack and bore.’

Tijuana Water Deliveries, Explained

/in , , , /by

Over the last few weeks, several stories have come out about water deliveries being made to the city of Tijuana. Here’s some of the basics behind this unique international agreement.  

Whose water is it? Mexico’s. Water delivered through the Emergency Deliveries Agreement is a portion of the Colorado River supplies allotted to Mexico under the 1944 Treaty.  

Where does it come from? Under normal conditions, Tijuana’s supply of Colorado River is diverted from the Morelos Dam, about 1 mile downstream of the California and Baja California boundary, south of Yuma, Ariz. Water is transported west through the Alamo Canal to Mexicali, and then through the Tijuana Aqueduct to Tijuana, for a total of about 150 miles.  

Under emergency conditions, Mexico’s Colorado River supply to Tijuana is diverted at Lake Havasu and transported through Metropolitan’s 242-mile Colorado River Aqueduct before being conveyed through MWD, Water Authority and Otay Water District distribution systems. 

Daytime papel picado framed view of the iconic landmark arch of downtown Tijuana, Baja California, Mexico.

When did deliveries start? The Agreement was signed in 1972, and several amendments (minutes) were signed since then that document the authorization of emergency deliveries to Mexico. Delivery volumes have varied from 0 to nearly 10,000 acre-feet per year; the maximum annual delivery volume, per the agreement, is 14,400 acre-feet.  

Emergency deliveries occurred throughout the 1970s and stopped from 1981-2002. Deliveries started up again from 2003-2012, with another hiatus from 2013- 2017. Most recently, Mexico has requested emergency deliveries every year from 2018 -2024, except for 2021. 

How many agencies are involved? A number of agencies from the federal, state, local and Mexico governments are involved. On the U.S. side, this includes the Bureau of Reclamation, the U.S. International Boundary and Water Commission, Metropolitan Water District of Southern California, San Diego County Water Authority and Otay Water District. South of the border, the National Water Commission, Mexico’s International Boundary and Water Commission, State Public Utility Commission of Tijuana (CESPT) and other agencies are involved. 

What does the current agreement include? The current agreement, which expires in 2027, includes procedures and schedules for annual emergency delivery requests, capacity determination by the California Agencies, base cost of deliveries calculation and fund balance requirements.   

With each annual request by Mexico, the California Agencies must agree to deliver the requested delivery volumes based on available capacity within their respective systems. Additionally, funds must be provided by Mexico in advance of water deliveries.
