Pure Water Oceanside-Potable Reuse-Sustainability Sustainble Building Week

SD Sustainable Building Week Features Water Reuse Projects

Representatives from three potable reuse projects under development in San Diego County will provide project updates during the inaugural “Sustainable Building Week San Diego” at 11 a.m. on Tuesday, April 13.

Hosted by the San Diego Green Building Council, Sustainable Building Week offers free virtual events from April 12 – 16 addressing sustainable practices and creating collaboration and networks among San Diego professionals involved with environmental stewardship and green building. All events are free and open to the public.

Sustainable Building Week and potable reuse

The San Diego County Water Authority hosts and moderates a panel titled “Potable Reuse: New Local Sources  of High-Quality Drinking Water for  San Diego County.” Potable reuse will provide a new source of safe, high-quality drinking water in San Diego County. Projects will create a local supply that is sustainable, drought-resilient, and benefits the environment. Additional sources of local water supply will also help prepare the region for future droughts and a changing climate.

Financially competitive and environmentally responsible

Attendees to the free virtual presentation will hear the latest updates on three San Diego County potable reuse projects currently under development. The presenters will describe how the potable reuse process purifies recycled water; reduces reliance on imported water; and is financially competitive and environmentally responsible.

Panelists include:

Cari Dale, Water Utilities Director, City of Oceanside, has been working towards meeting the Oceanside City Council’s goal of 50% local water supply development by the year 2030, a goal which will be achieved in part by the implementation of Pure Water Oceanside.

John Stufflebean, Assistant Director, Water Utilities Department, City of San Diego, currently the Assistant Director for the Pure Water and Technical Services Branch. Pure Water San Diego is the $5 billion project designed to generate nearly one-half of San Diego’s water demand from purified wastewater.

Kyle Swanson, Director of Advanced Water Purification, Padre Dam Municipal Water District, provides leadership and guidance in the design and implementation of the East County Advanced Water Purification Project.  He has over 20 years of experience in water-related industries and is a licensed distribution and treatment operator and certified public manager.

Moderating the program is Lesley Dobalian, Principal Water Resources Specialist for the San Diego County Water Authority.

Registration to attend the program is free. Attendees can RSVP and receive a link for the presentation on the SDGBC Sustainable Building Week website.

Mayor Gloria Announces City on Track to Develop 50% of its Water Locally

As part of his efforts to create a more sustainable future for all of us, Mayor Todd Gloria today publicly released a new analysis of San Diego’s future water needs that indicates that the City will develop more than 50% of its water locally by 2045, in large part due to the Pure Water recycling program. This will be a dramatic increase in local water supply, which currently requires the City to purchase 85% to 90% of its water from imported sources.

Miramar Reservoir Marks 60 Years of Service

For 60 years, Miramar Reservoir has been an integral part of the City of San Diego’s drinking water system and offers San Diegans a popular recreational area. Now, the reservoir is being called into service to play a vital part in San Diego’s future Pure Water system to sustain a reliable water supply.

The City of San Diego is commemorating the 60th anniversary of Miramar Reservoir, its role in the region’s history, and the part the reservoir will play in the future.

“We celebrate not only Miramar Reservoir’s past, but the critical role it will play when the Pure Water system is completed,” said Shauna Lorance, director of the San Diego Public Utilities Department. “Miramar Reservoir will continue to be a key part of our water system for many years to come.”

Miramar Reservoir marks 60

Miramar was the last of the City’s nine reservoirs to be developed. It was completed in 1960 as part of the second San Diego Aqueduct. The location previously had been the site of a small reservoir serving the vast ranch of newspaper publisher Edward W. Scripps.

Water flowing south to the reservoir originates from both the Colorado River Aqueduct and the California Aqueduct. The earthen embankment dam has a maximum height of 165 feet measured from the downstream toe, and has a base of 1,180 feet.

It was constructed by contractors Einer Brothers Inc. of Escondido and McCammon Construction, for $1.42 million. Land acquisition and engineering costs were approximately $730,000. Funds for the project came from an $11 million water bond approved by San Diego voters in June 1958.

When full, the reservoir covers 274 surface acres, reaches a maximum water depth of 114 feet, and has four miles of shoreline. Miramar Reservoir has a water storage capacity of 6,682 acre-feet.

Miramar Water Treatment Plant, which was completed in 1962 at a cost of $3.5 million, and expanded and upgraded in 2010, treats and filters drinking water distributed to customers in the northern part of San Diego.

Since the mid-1960s, the reservoir has been a popular recreational destination. An estimated 100,000 people visit Miramar each year to enjoy jogging, walking, biking, fishing, boating, picnicking, among other activities.

When the Pure Water system comes online, Miramar Reservoir will switch from holding imported water to holding purified water received through a pipeline from the planned North City Pure Water Facility. After water has been purified at the North City Pure Water Facility, it will then be transferred via pipeline to Miramar Reservoir. The Miramar Water Treatment Plant will clean the water again, and the water will be distributed to homes and businesses throughout northern San Diego.

Miramar Reservoir will continue use into the foreseeable future as it helps provide one-third of San Diego’s water supply locally by the end of 2035.

Padre Dam Named Utility of the Future Today

Padre Dam Municipal Water District’s leadership in the development of water reuse as well as its strong workplace culture received national recognition with a 2020 Utility of the Future Today award. The award honors substantial excellence in the operation of water sector services.

“We are honored to be recognized as a groundbreaking agency in the area of water reuse,” said Allen Carlisle, Padre Dam general manager and CEO. “This distinction highlights our ongoing commitment to innovative improvements in service of our customers.”

The Utility of the Future Today program celebrates the achievements of water utilities transforming from the traditional wastewater treatment system to a resource recovery center and leader in the overall sustainability and resilience of the communities they serve. It was launched in 2016 by the National Association of Clean Water Agencies, the Water Environment Federation, the Water Research Foundation, and the WateReuse Association, with input from the U.S. Environmental Protection Agency.

Water reuse efforts recognized

Padre Dam Municipal Water District has been recycling water since 1958. The District’s Ray Stoyer Water Recycling Facility produces around two million gallons per day of recycled water.

Padre Dam is now working on a regional water and wastewater solution in a collaborative partnership between Padre Dam and the County of San Diego, City of El Cajon, and Helix Water District to expand on the history of water reuse through the East County Advanced Water Purification Project.

The project will create a new local, sustainable, and drought-proof drinking water supply using state-of-the-art technology to purify recycled water and diversify East San Diego County’s water supply, while reducing the region’s dependence on imported water. This new water supply will provide approximately 30% of East County’s water demand, and nearly eliminates the discharge of East County’s treated wastewater into the Pacific Ocean.

Padre Dam is currently the Program Administrator for the regional East County Advanced Water Purification Program.

Workplace culture fosters collaboration

Padre Dam Municipal Water District’s strong organizational culture of collaboration, learning, service, and transparency also received recognition. The award cited Padre Dam as an agency that encourages the ongoing learning process and the improvement of its workforce in the planning and decision process. This culture empowers every employee to think creatively, cultivating an organizational culture of innovation.

Padre Dam has enjoyed a successful and progressive workforce partnership with management, labor, and its Board of Directors for decades. Over the last several years, the District invested in the reinvention of its internal workforce development program to meet the changing needs of its modern workforce.

Now called the “Pipeline,” the program embraces a philosophy enabling broad-based participation in the organization’s decision-making processes.

“The Pipeline relies on the primary principle that we can better serve our customers by conducting activities in a collaborative and transparent manner,” said Carlisle. “Long before our employees became essential workers providing vital services during the pandemic, Padre Dam recognized their tremendous value to our organization. This award is for each and every one of our employees who have performed in an exemplary way when they were needed most.”
