East County Advanced Water Purification Project Progressing

/in , , /by /Water News Network

The East County Advanced Water Purification project is progressing, with construction underway at multiple East San Diego County locations. The project will create a new, local, sustainable, and drought-proof water supply using state-of-the-art technology to purify East San Diego County’s recycled water.

Construction for the East County AWP is expected to be completed in 2025, and water production will begin in 2026. When completed, the project is expected to provide approximately 30% of current drinking water demands for East San Diego County residents and businesses.

Water treatment facilities are under construction north of Santee Lakes. Concrete work is underway on the water recycling and solids handling facilities. About 24,000 cubic yards of concrete have been poured, marking nearly 50% of the total concrete used at this site. Once complete, there will be enough concrete to fill 16 Olympic-sized swimming pools.

The advanced water purification facility and visitors center are also taking shape with the installation of underground piping and conduits.

Pipeline construction in Santee

Pipeline construction continues on Fanita Parkway north of Ganley in Santee. Biking and hiking access to the trails north of Ganley are temporarily located at the end of Strathmore to provide a safe space for construction.

The purified water pipeline will travel east through Santee and Lakeside, ending at Lake Jennings. Two additional pipelines will be constructed south of the new facilities past Carlton Oaks Drive to a pump station just south of the Carlton Oaks Golf Course.

Most pipeline work will be trenched, placed, and covered, while the remainder will be installed using trenchless technologies and methods. There may be some impacts from construction, including road travel delays. Construction hours vary depending on the project elements being completed.

The purified water pipeline running from the advanced water purification facility north of Santee Lakes to Lake Jennings is 10.2 miles long.

An interactive map allows viewers to zoom in and click on project areas to find active construction zones, schedules, work hours, and other information. Communication will include mailers, email updates, road signs, interactive maps, webpage updates, and presentations to community groups throughout the project area.

Groundbreaking ceremony in 2022

The June 2022 groundbreaking followed the approval of project construction on May 19, 2022, by the East County AWP Joint Powers Authority that owns and operates the Program. The Joint Powers Authority is a collaborative partnership between four agencies: Padre Dam, the City of El Cajon, the County of San Diego and Helix Water District. The project is estimated to create 2,500 jobs in the region.

How Bad Will California’s Winter Be? Weather Outlook for North and South

/in , , /by /Newsweekby Anna Skinner

El Niño has arrived, and the climate pattern is likely to bring above-average moisture to the southern U.S. this winter.

El Niño is one of two climate patterns that greatly impact Earth’s weather. La Niña recently culminated in the spring, ending a multiyear period in which the pattern influenced the weather. El Niño started in June, and the National Oceanic and Atmospheric Administration’s (NOAA) most recent update has identified El Niño as having high odds of being historically strong.

That means parts of California could see another wet winter, a welcome weather pattern as many of the state’s lakes and reservoirs continue to recover from a years-long drought. But an El Niño year doesn’t guarantee excess moisture in Southern California.

Tearing Down Dams Could Save Western Rivers — and Also Make Climate Change Worse

Deep in the bowels of Idaho’s Brownlee Dam, Neal Lincoln is ready to offer a demonstration.

Almost 40 feet below the surface of the Snake River — whose waters originate in Yellowstone National Park, then cascade down the Rocky Mountains and course across Idaho — Lincoln makes a call to the power plant control room. The narrow hallway where we stand waiting is chilly, the air dank and the floor covered with leakage from the river.

An Atmospheric River Will Drench Northern California Early This Week — But Entirely Miss Greater San Diego

An atmospheric river will bring significant rain to Northern California Monday and Tuesday but entirely miss San Diego County, which is days away from wrapping up an otherwise wet year, the National Weather Service said.

But there will be a slight chill to the air along the San Diego coastline — the kind that reminds people that it’s a good idea to keep a sweater handy. And you’ll need your winter wetsuit before long.

Conditions were much warmer than average this summer across the Pacific Northwest, AZ and NM, and across much of far northern California. Elsewhere in CA, summer temperatures were mostly near long-term averages or even somewhat below in some of the SoCal coastal counties.

San Diego County Water Authority Honored for Climate Change Efforts

/in , /by

The San Diego County Water Authority has earned Climate Registered gold status from The Climate Registry for the fourth consecutive year. The Water Authority was recognized for verifying and publicly reporting its greenhouse gas emissions, an effort that fosters transparency for the agency’s climate mitigation initiatives and helps the agency track and validate emissions reductions in the future.

The Climate Registry operates North America’s largest voluntary registry for greenhouse gas (GHG) emissions. The Water Authority’s 2021 and 2022 inventories were verified and published in The Climate Registry’s public database in July and September, earning the agency gold status for both years. The agency also published its 2019 and 2020 inventories, earning the Water Authority gold status for those years. In addition, the Water Authority has met all California state aligned GHG reduction targets, while decreasing its emissions over the past 13 years compared to its state-aligned baseline year.

“Reducing greenhouse gas emissions is a key part of the Water Authority’s Climate Action Plan and our commitment to the environment,” said Water Authority Board Chair Mel Katz. “As a climate leader, we continue to develop forward-thinking solutions that increase our contribution to energy and water efficiency efforts across the state.”

The Water Authority works with its 24 member agencies to deliver safe and reliable water supplies across San Diego County. Sustainability has been an important part of the agency’s commitment for years. Water-use efficiency not only lessens the Water Authority’s dependence on imported water, but it also reduces energy costs and the greenhouse gas emissions associated with transporting and treating water.

Climate Action Plan

As a centerpiece of its sustainability efforts, in 2014 the Water Authority voluntarily developed a Climate Action Plan and updates it every five years, comparing GHG emissions against a baseline and tracking progress toward State of California goals. Since the plan’s adoption, the Water Authority has conducted annual GHG inventories and provides updates to the Board of Directors. Verification of the annual inventory by a third-party is another step toward validating the Water Authority’s climate mitigation efforts for stakeholders.

The Climate Registry is a nonprofit organization governed by U.S. states and Canadian provinces and territories. The registry designs and operates voluntary GHG reporting programs globally, and assists organizations in measuring, reporting and verifying the carbon in their operations to manage and reduce it. The registry also builds capacity for emissions reductions by government agencies, and spearheads innovative projects such as the Water-Energy Nexus Registry.

“The San Diego County Water Authority’s continued achievement of Climate Registered gold status through reporting years 2021 and 2022 demonstrates sustained and consistent leadership in emissions disclosure,” said Charles Pope, Director of Registry Services for The Climate Registry. “The Climate Registry is proud to recognize SDCWA’s extraordinary commitment to transparency, which sets a clear example for all organizations in California.”
