Pure Water Oceanside-Potable Reuse-Sustainability Sustainble Building Week

Water Authority Board Supports Regional Potable Reuse Projects

/in , /by

The San Diego County Water Authority’s Board of Directors today unanimously approved a formal resolution reaffirming its longstanding support for potable reuse and water recycling projects developed by local member agencies across the region.

“Projects such as Pure Water San Diego, Pure Water Oceanside and the East County Advanced Water Purification Project are critical to the continued development of local water sources that help sustain the region’s 3.3 million residents and $245 billion economy,” said Water Authority Board Chair Gary Croucher. “The Water Authority has long supported water reuse and recycling projects, and we will continue to collaborate with member agencies in developing these vital local resources.”

Water supply diversification

For more than two decades, the Water Authority has promoted the advancement of water recycling and reuse in San Diego County as part of the region’s water supply diversification and reliability strategy.

The agency has sponsored and supported legislation to speed the development of potable reuse regulations in California, and has worked as an active member of the WateReuse Association to help shape the statutory and regulatory framework for potable reuse in the state. And Water Authority investments in high-priority, highly reliable water from the Colorado River support the development of local resources by delivering a low-cost baseload of water that can be recycled and repurified.

Potable reuse project funding

In addition, the Water Authority has advocated for robust funding in state bond measures, including seeking the inclusion of up to $500 million to expedite potable reuse and advanced water treatment projects in a legislative bond measure targeted for the November 2022 ballot. The Water Authority also helped secure nearly $500 million for local projects from the Metropolitan Water District of Southern California in 2019 and 2020, and most of that money was for potable reuse.

Potable reuse relies on advanced treatment technologies to produce a high-quality drinking water that is locally controlled, drought-resilient, and reduces wastewater ocean discharges. Every gallon of recycled or repurified water reduces the need to import or develop other supplies.

Recycled water, potable reuse projects under construction

Approximately 33,000 acre-feet of recycled water is expected to be reused within the Water Authority’s service area annually by 2025. The volume is expected to continue growing as new and expanded potable reuse plants come online. They are projected to produce more than 112,000 acre-feet per year of new drinking water supplies by 2045, enough to meet nearly 18% of the region’s future water demand.

Two of the first three potable reuse projects are now under construction in San Diego County:

A third project, the East County Advanced Water Purification Program, a combined effort by the City of El Cajon, Padre Dam Municipal Water District, the County of San Diego, and the Helix Water District, is in the design/pre-construction phase.

Arizona Changes ‘Use It or Lose It’ Water Law

/in , , /by /AZPM News (Arizona Public Media)by Ariana Brocious

A change in Arizona water law will let farmers and ranchers conserve water without worrying about losing their rights to it in the future.

Like most western states, Arizona water rights are “use it or lose it,” meaning that if farmers or ranchers don’t use their full amount for a certain number of years they risk forfeiting their rights forever. Kim Mitchell, senior water policy advisor with Western Resource Advocates, said that disincentivizes conservation at a time when we increasingly need more of it.

“We’re on the heels of 20 years of drought and now we have these recent commitments to divert less water from the Colorado River. And annual flow in many of our water courses have been decreasing with climate change and the drought that continues to grip the region,” Mitchell said.

Red Alert Sounding on California Drought, as Valley Gets Grim News About Water Supply

/in , , /by /The Sacramento Beeby Dale Kasler and Ryan Sabalow

A government agency that controls much of California’s water supply released its initial allocation for 2021, and the numbers reinforced fears that the state is falling into another drought.

The U.S. Bureau of Reclamation said Tuesday that most of the water agencies that rely on the Central Valley Project will get just 5% of their contract supply, a dismally low number. Although the figure could grow if California gets more rain and snow, the allocation comes amid fresh weather forecasts suggesting the dry winter is continuing.

Will the Climate Crisis Tap Out the Colorado River?

/in , , /by /High Country Newsby Nick Bowlin

Southern California farmers spend their winters watching the snowpack in the Colorado Rockies, and what they see is the climate crisis hitting hard. When it melts, the snow that falls on these peaks will, eventually, make its way into the Colorado River, which connects the Southwest like a great tendon, tying the Continental Divide in Colorado to Southern California’s hayfields, where the Imperial Irrigation District is one of the country’s largest, and pouring from the faucets of urban users in Los Angeles and San Diego.

Sierra Snowpack Has Major Drop Over the Past Decade

Sierra snowpack is so vital to California as it provides one third of the state’s water supply and it seems more and more lately we are seeing this dwindle. You can see from 2002 to 2011 60% of the time the Sierra snowpack was 100% or better, a pretty good trend.

The state’s Ocean Protection Council has awarded $1.3 million to preserving and safeguarding estuary habitat at Elkhorn Slough, which boasts the second-largest tidal salt marsh in California. The wetland, once degraded by farming activities such as diking, is at risk of impacts from climate change — particularly rising sea levels.

San Diegans, How Much Would You Tax Yourself to Prevent Floods, Boost Water Quality?

San Diego officials plan to spend the next five months analyzing what size tax increase city voters would likely support in November 2022 to pay for projects that boost flood prevention and water quality.

The ballot measure would be the first opportunity for San Diegans to vote to raise taxes on themselves to tackle an estimated $6 billion infrastructure backlog that city officials began calling San Diego’s No. 1 challenge eight years ago.

Colorado River Study Means It’s Time to Cut Water Use Now, Outside Experts Say

/in , , /by /Tucson.comby Tony Davis

Less water for the Central Arizona Project — but not zero water. Even more competition between farms and cities for dwindling Colorado River supplies than there is now.

More urgency to cut water use rather than wait for seven river basin states to approve new guidelines in 2025 for operating the river’s reservoirs.

That’s where Arizona and the Southwest are heading with water, say experts and environmental advocates following publication of a dire new academic study on the Colorado River’s future. The study warned that the river’s Upper and Lower basin states must sustain severe cuts in river water use to keep its reservoir system from collapsing due to lack of water.

That’s due to continued warming weather and other symptoms of human-caused climate change, the study said.

Drought-Stricken West Holds Out For More Than Just Dry Snow

It’s a picture-perfect scene — the snow-dusted Sandia Mountains providing a backdrop to the dormant willow and cottonwood trees lining the Rio Grande.

While the recent snow has provided a psychological salve to the pains of a persistent drought, it won’t go far in easing the exceptional conditions that have taken hold of New Mexico over the past year.
