EPA Action Plan to Boost Water Reuse Across U.S.

The U.S. EPA today released a draft plan to advance water reuse nationally at the WateReuse Association Symposium in San Diego.

The National Water Reuse Action Plan identifies 46 proposed actions organized around 10 strategic objectives, including leadership and collaboration, to support the implementation of water reuse.

“Forty states anticipate experiencing fresh water shortages in certain regions within their borders over the next decade,” said David Ross, EPA’s assistant administrator for water. “Diversifying our nation’s water portfolio must be a nationwide priority, and water reuse has the potential to ensure the viability of our water economy for generations to come.”

The draft plan incorporates federal, state, tribal and local water perspectives and highlights key actions that support consideration and implementation of water reuse.

The San Diego County Water Authority and its 24 member agencies have worked for decades to increase the region’s water supply reliability through supply diversification, and the Water Authority collaborated with its member agencies to submit comments to the EPA before the draft was released.

National Water Reuse Action Plan a ‘game changer’

The draft plan will be open for public comment for 90 days following its publication to the Federal Register. During that period, EPA will solicit feedback about how to prioritize and implement the proposed actions.

EPA’s goal is to issue a final plan that will include clear commitments and milestones for actions that will further water reuse to bolster the sustainability, security and resilience of the nation’s water resources, according to the agency.

“The National Water Reuse Action Plan will be a game changer,” said Patricia Sinicropi, executive director of the WateReuse Association. “Communities across the country are incorporating water reuse into their water management strategies as a proven method for ensuring a safe, reliable, locally controlled water supply – essential for livable communities, healthy environments, robust economies and a high quality of life.”

“California is widely recognized as a national and world leader in water recycling,” according to the California WateReuse Action Plan, released in July 2019. “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.”

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.

Water Agencies Approve Funds for East County Advanced Water Purification Project

The East County Advanced Water Purification Project is moving forward after a new funding agreement was approved.

The program’s partner agencies – Padre Dam Municipal Water District, the City of El Cajon, Helix Water District and the County of San Diego – recently approved the Interim Funding Agreement. The final vote from the County of San Diego took place July 10.

The project is expected to begin producing water in 2025.

Purified water reduces dependence on imported water

The agreement requires each agency to commit $2.35 million ($9.4 million total) toward the program, with the aim to create a new, local, sustainable, and drought-proof drinking water supply using state-of-the-art technology to purify East San Diego County’s recycled water.

“This is an important milestone toward the completion of this innovative and much-needed program, said Allen Carlisle, CEO and general manager of Padre Dam Municipal Water District. “Working together with our partners, we are moving one step closer to reducing our dependence on imported water and putting the mechanisms in place to support our economy and quality of life well into the future.”

Once complete, the East County Advanced Water Purification Program will generate up to 11.5 million gallons per day of new drinking water. This represents approximately 30 percent of current drinking water consumption for residents within the Padre Dam service area (Santee, El Cajon, Lakeside, Flinn Springs, Harbison Canyon, Blossom Valley, Alpine, Dehesa and Crest), and the Helix service area (including the cities of Lemon Grove, La Mesa, and El Cajon, and the Spring Valley area). This represents approximately 373,000 residents.

The project will recycle East San Diego County’s wastewater locally, and then purify the recycled water at an advanced water treatment facility using four advanced water purification steps producing water that is near-distilled in quality. The purified water will then be blended with water in Lake Jennings, treated again at the Helix R.M. Levy Water Treatment Plant and then distributed into the drinking water supply.

Industry Day planned for prospective designers and contractors

Next steps for the project include formation of a Joint Powers Authority between Padre Dam Municipal Water District, the City of El Cajon, and the County of San Diego to serve as the governing body for the program.

An industry day is being planned in mid-August to provide notice to prospective designers and contractors on the initiation of a selection process for the progressive design-build packages that will begin posting in Fall 2019.

Partner agencies also continue to pursue grant and loan opportunities to help fund the estimated $528 million project.

The water-recycling project is intended to diversify East County’s drinking water supply and reduce the region’s dependence on imported water. It also helps the region in achieving long-term compliance with the Clean Water Act.

East County Advanced Water Purification Project on Track for 2025

The East County Advanced Water Purification Project is moving forward toward its anticipated completion date after the Padre Dam Municipal Water District’s Board of Directors approved the required environmental report.

“The approval of the environmental report for this project brings us another step closer to producing a local water supply for East County and improving the reliability of the water service for our community,” said Allen Carlisle, Padre Dam CEO/General Manager. “We are on track for the project to begin providing water to the East San Diego communities by 2025.”

The East County Advanced Water Purification Project is a collaborative partnership between the Padre Dam Municipal Water District, Helix Water District, County of San Diego and City of El Cajon. The partnership’s purpose is bringing a new, local, sustainable and drought-proof water supply to the East County, using state-of-the-art technology.

Advanced technology improves water reliability for East County

The project will recycle East San Diego County’s wastewater locally, and then purify the recycled water at an advanced water treatment facility using four advanced water purification steps. The purified water will then be pumped into Lake Jennings, treated again at the Helix Levy Treatment Plant and then distributed into the drinking water supply.

The water recycling project will help diversify East County’s drinking water supply, reducing the region’s dependence on imported water. It also helps the region in achieving long-term compliance with the Clean Water Act (CWA), the primary federal law in the U.S. helping to restore and maintain the integrity of the nation’s waters by addressing pollution and improving wastewater treatment. It is one of the United States’ first and most influential modern environmental laws.

Upon its completion, the East County Advanced Water Purification Project will produce up to 12,900 acre-feet per year, or 11.5 million gallons per day of new local drinking water supply.

“This project is forward-thinking, innovative and promises to give East County greater water independence and reliability,” said San Diego County Supervisor Dianne Jacob, who represents the East County region. “It will give us more local control over our most precious resource — and that’s great news for residents and businesses.”
