Oceanside Leads County With Plan to Make Recycled Water Safe to Drink

Oceanside celebrated the start of construction Wednesday on a project that could make it the first city in San Diego County to be drinking recycled water by 2022.

At least two other cities or water districts are close behind on similar projects, and several more agencies are considering plans to make potable recycled water a significant portion of their supply.

“We are one step closer to completing a project that will supply 30 percent of Oceanside’s water,” said Cari Dale, the city’s water utilities director, to guests at the city’s San Luis Rey Water Reclamation Facility.

Water Board OKs $3.2M Live Oak Water Plant Land Purchase

CAPITOLA — A planned water recycling plant project took a leap forward this week after approval of a new land purchase.

The Soquel Creek Water District board voted unanimously Tuesday night to exercise its $3.2 million option to purchase nearly 2 acres of Live Oak light industrial property at the corner of Chanticleer and Soquel drives. The site at 2505 Chanticleer Ave. will be the future home of an advanced purification water plant, which the district’s dubs its Pure Water Soquel project.

First Advanced Water Purification Facility in San Diego County is On the Map

City of Oceanside officials and regional water industry leaders gathered today to break ground on Pure Water Oceanside, the first advanced water purification facility in San Diego County. The $67 million project – scheduled to be completed in 2021 – will purify recycled water sourced from the San Luis Rey Water Reclamation Facility.

“Today, we put Pure Water Oceanside on the map and are one step closer to achieving the goal of greater water-independence for our city, residents and businesses,” said Cari Dale, Oceanside’s water utilities director. “This future-focused project will provide multiple benefits by reusing our water resources to their full potential.”

Reducing dependence on imported supplies

The local project will reduce Oceanside’s dependence on imported water by more than 30%. The purification process is inspired by the natural water cycle and reduces the amount of recycled water discharged into the ocean.

The project is partially funded by the Local Resources Program through the San Diego County Water Authority and Metropolitan Water District of Southern California.

“The tremendous conservation focus, water infrastructure planning and investment by the Water Authority and its 24 member agencies has put our regional supplies in solid standing,” said Water Authority General Manager Sandra L. Kerl. “The mission of providing reliable water supplies to San Diego County can be likened to a puzzle; there are many pieces that fit together to create an overall solution. Our next increment of supply in the San Diego region is from potable reuse projects.”

Improving local resources in a sustainable way

During today’s ceremony, city leaders and water experts placed a giant Google Maps “location pin” into the ground at the San Luis Rey Water Reclamation Facility, which marked that the new recycled water project is now officially on the map. Guests were invited to take tours of the existing facility to see the location of the new infrastructure and learn how purification technology works.

“Being on the map signifies not only that this project will be an historic landmark, but also a symbolic one that will serve as an example for other cities and agencies that are interested in initiating this type of program,” said Jack Simes, acting area manager at the United States Bureau of Reclamation.

In addition to reducing dependence on imported water supplies, the project will improve groundwater resources and help protect the environment by reducing dependency on imported supplies that can disrupt ecosystems.

“We need to pursue new and innovative solutions to protect our land and water for future generations,” said Congressman Mike Levin, whose district includes coastal North County. “Pure Water’s commitment to providing over 30% of the drinking water in the City of Oceanside in a way that is clean, safe, sustainable and environmentally sound is commendable.”

Technologically advanced water purification process

Pure Water Oceanside will use state-of-the-art water purification technology that replicates and accelerates nature’s natural recycling process.

First microfiltration filters remove bacteria and suspended solids from reclaimed water. Then ultra-fine reverse osmosis filters remove salt, viruses, other bacteria, pharmaceuticals and chemicals. Next, the water is treated with ultraviolet light and advanced oxidation technologies that neutralize any remaining substances.

Minerals are injected back into the water before the water is added to Mission Basin in Oceanside. Water can then be extracted from the aquifer, treated once again at the Mission Basin Groundwater Purification Facility and finally, distributed to residents and businesses.

Ensuring water for future generations requires investing and investigating big ideas, according to Sandy Kerl.

Kerl, acting general manager of the San Diego County Water Authority, shared some of those ideas today in San Diego, as she delivered the opening remarks at the California-Nevada Section of the American Water Works Association annual fall conference, which runs through Thursday at the Town and Country Hotel Convention Center.

California Moves To Boost Recycled Water

A new plan recommends four strategies to advance water reuse in California over the next three decades – an important part of both the state and regional water resilience portfolio.

The California WateReuse Action Plan includes a comprehensive set of proposed actions that will more than double the use of water recycling in California and help prepare the state for the impacts of climate change, according to WateReuse California, which released the plan in July.

But getting to that goal will require several steps, including: Completing research to advance water recycling and potable reuse; developing and streamlining recycled water regulations and permitting; increasing grant and loan opportunities to expand recycled water infrastructure; and, implementing integrated regional planning.

The U.S. EPA is developing a similar plan to advance water reuse nationwide.

San Diego water agencies collaborate on plan

Recycled water is expected to be the next major source of local water supply for the San Diego region – and the region has a long history of working together toward that goal.

The San Diego County Water Authority collaborated with its member agencies to provide feedback on the plan’s development.

“We appreciate how this new plan aims to increase water supply diversification, including recycled water,” said Lesley Dobalian, principal water resources specialist with the Water Authority, and a contributor to the final action plan.

“Within the next 15 years, potable reuse and recycled water is projected to make up more than a quarter of San Diego County’s supply, but reaching our potential will depend in part on statewide implementation of the plan’s key findings,” Dobalian said.

Water Resilience Portfolio

In July, the Water Authority Board endorsed Governor Gavin Newsom’s Executive Order N-10-19, directing development of a water resilience portfolio approach that meets the needs of California through the 21st century.

On July 18, state officials toured San Diego County water infrastructure to see the region’s successful water portfolio approach for supply diversification, as they work to create the statewide water resilience portfolio.

In San Diego County, several agencies are developing or expanding water recycling plans, including the City of San Diego, Padre Dam Municipal Water District, Helix Water District, the City of Oceanside, and several additional projects in North County.

National water reuse action plan

At the national level, EPA is also developing a Water Reuse Action Plan, or WRAP, to advance water reuse. The Water Authority met with its member agencies and submitted comments to the U.S. EPA for the WRAP.

A draft WRAP is expected to be released by the federal agency at the national WateReuse Association Symposium September 8-11 in San Diego.

“California is widely recognized as a national and world leader in water recycling,” according to the California WateReuse Action Plan. “Recycled water supplies offset approximately 9% of the state’s urban water demands and agricultural reuse provides reliable water supplies for farmers throughout the state.”
