Earth Day-Earth Day 2023-Landscape Makeover-Water Conservation

Every Day is Earth Day for Water Agencies in San Diego County

/in , /by

“Invest in Our Planet” is the theme for Earth Day 2023. Investing in sustainable, local water supply sources and conservation has long been a way of life in San Diego County by water agencies and residents.

“Investing in our planet can take many forms, and the challenges we face differ from community to community,” said San Diego County Water Authority General Manager Sandra L. Kerl. “One investment I encourage San Diegans to think about on this Earth Day is landscape transformation. This is important because the biggest users of water at our homes are our landscapes – perhaps as much as 70% of our water use, depending on where we live.”

Sustainability is a priority of the Water Authority and its 24 member agencies. Maintaining a sustainable water supply ensures the vitality of San Diego County’s $268 billion economy and a safe, reliable supply for the region’s 3.3 million residents.

Earth Day and WaterSmart San Diego

Along with federal, state and local government support, including grant funds, the Water Authority and its 24-member agencies have developed diversified, sustainable, local water supply sources. The agencies also collaborate to secure funding for programs that help  residents and businesses use water efficiently and smartly.

Using water efficiently has long been a way of life in the region. Conserving more of our most precious resource is a responsibility that comes with living in San Diego’s Mediterranean climate. Over the past decade, residents and businesses across the county have adopted “WaterSmart” plants, irrigation technologies and habits that not only save money, but also create vibrant yards, reduce energy use, protect natural resources and reduce landscape maintenance.

Invest in the Planet by Living WaterSmart

The Water Authority partners with other agencies and organizations to offer a variety of WaterSmart tools, including classes and rebates, along with a water-use calculator and other resources.

Increasing local supply sources also benefits the greater Southwest U.S. by reducing demand on imported sources. A hotter, drier climate in the arid west requires climate adapation solutions and region-wide collaboration to ensure water supply reliability.

Sustainable water projects

The Water Authority and its 24 member agencies have long-embraced sustainable practices to conserve water and energy. All water agencies work together on forward-thinking projects to expand local supply sources. By investing locally in water recycling, desalination and potable reuse projects, the agencies reduce the need for imported water, freeing those supplies for other parts of California and the Southwest U.S.

Olivenhain Recycled Water Pipeline

A new recycled water pipeline in Encinitas is helping to reduce the region’s dependence on imported water supply.

East County AWP

Scheduled to be complete in 2026, the East County Advanced Water Purification Program will generate up to 11.5 million gallons per day of purified water— meeting approximately 30% of current drinking water demands for East San Diego County residents and businesses. “In 2045, potable reuse projects are going to provide up to 20% of the water that we need here in San Diego County,” said San Diego County Water Authority General Manager Sandra L. Kerl at the June 2022 groundbreaking. “This region has been excellent in its innovation and planning for water needs for the region.”

“In this year when many areas of California and the West are facing extreme hardships with drought, the East County AWP is really another step forward in reliability for its water supply partners and the region,” said Sandra L. Kerl, General Manager, San Diego County Water Authority, at the June 1 groundbreaking ceremony for the recycled water project. Photo: East County Advanced Water Purification Program

Pure Water Oceanside

The $70 million Pure Water Oceanside project uses advanced technology, including ultrafiltration, reverse osmosis and advanced oxidation to provide 3 million gallons per day or more than 20% of the City of Oceanside’s drinking water supply. The source of the recycled water to create the purified water is from the city’s own San Luis Rey Water Reclamation Facility.

Cutting-Edge Renewable Energy Projects

Renewable energy from natural resources such as sunlight, wind and water is quickly becoming a critical component of California’s power supply. As a water supplier, the Water Authority pursues a variety of hydroelectric and solar energy projects to help reduce energy costs and stabilize water rates.

A power purchase agreement with CleanCapital enabled the Water Authority to install solar power systems at no cost. The solar power systems installed at the Water Authority’s Kearny Mesa headquarters, Escondido Operations Center and Twin Oaks Valley Water Treatment Plant produce an estimated 2.5 million kilowatt-hours of renewable energy each year. The 20-year agreement with CleanCapital will save the Water Authority approximately $3 million over the lifetime of the agreement, and supports the agency’s commitment to sustainability.

Colorado River Board of California-River Board-Tour

San Diego County Water Authority Hosts Colorado River Board of California

/in , /by

The San Diego County Water Authority will host water leaders from throughout Southern California March 15 for the monthly meeting of the Colorado River Board of California. On March 14, before the formal meeting, CRB board members will tour projects in the region that promote water resiliency.

The CRB will consider the complex water supply issues facing the Southwest U.S. during its meeting. San Diego Congressman Scott Peters is also scheduled to address the CRB.

Colorado River Board of California

The tour is part of a new program implemented by CRB, under the leadership of Chair JB Hamby, Imperial Irrigation District’s representative, and Vice Chair Jim Madaffer, the Water Authority’s representative and Water Authority board member, to build greater awareness of each CRB member agency’s efforts to serve their region and manage their river supplies.

“The Colorado River Board is so important to ensuring California’s voice is heard on the river, especially during these difficult times as we work to find collaborative solutions to the river’s challenges now and into the future,” Madaffer said. “We look forward to showcasing the local supply projects, online now and planned, that create water resiliency locally, but that also reduce the demand on the river.”

Established in 1937, the CRB is a state agency tasked with protecting the interests and rights of the state and its agencies in water and power resources from the Colorado River.

The Water Authority is a member of the CRB along with IID, the Metropolitan Water District of Southern California, the Coachella Valley Water District, the Palo Verde Irrigation District, the Los Angeles Department of Water and Power, the California Department of Water Resources, and the California Department of Fish and Wildlife. CRB representatives, including two additional members from the public, are appointed by the Governor.

“The desalination plant is not only important to our region, but the Water Authority believes the plant could be part of an overall long-term solution to support Lake Mead, California’s critical river reservoir, under a proposal we are considering to expand the plant,” said Madaffer.

Water purification

Now under construction, the East County Advanced Water Purification facility, or East County AWP, is a collaborative partnership between two Water Authority member agencies, the Padre Dam Municipal Water District and the Helix Water District, and the County of San Diego and City of El Cajon.

The plant is projected to generate a local, reliable and drought-proof drinking water supply utilizing state-of-the-art technology to recycle and reuse the region’s wastewater. The East County AWP is expected to produce 30% of East San Diego County’s water supply by early 2026, and is one of the innovative water purification facilities in the county either in operation or in development.
