The Water Utility Climate Alliance has added the Water Authority’s efforts to reduce greenhouse gas emissions to its mitigation case studies library. The case studies provide valuable information and inspiration for greenhouse gas mitigation or sewage thermal energy use projects from concept to implementation for water utilities across the U.S.
After two years of solid drought, and four months into California’s “wet” season, we don’t know if this year will be wet or dry. This is normal for California. But this year’s monthly precipitation “whiplash” is unusual.
For northern California, October was the 2nd wettest October in 102 years of record (400% of average October from one 2-day storm!). November was the 31st driest November (50% of average). December was the 23rd wettest December (160% of average), and January was the 7th driest January on record (16% of average).
The start of the wet season was promising in California, with a record-breaking atmospheric river in October and an onslaught of storms in December, but the weather forecast has remained persistently dry since the start of the year — with no hope for rain in the immediate future.
The lack of rain during what is usually the wettest time of the year is problematic in a drought-plagued state that needs to replenish its water supply and dampen a wildfire-prone landscape. The last hope that remains for winter is a surge of precipitation in late February and in March. What are the chances of that even happening?
Well, I don’t need to tell most folks twice: January 2022 was an exceptionally dry month across most of California and Nevada. Some spots saw a bit of rain and snow during the first couple days of the month, but others saw nothing at all; the last 25 days of the month brought essentially zero precipitation to the entire region. As a result, January 2022 will go down in the record books as the driest January on record (since at least 1895) for most of the San Joaquin Valley, the Central and Southern Sierra, and pockets of the Sacramento Valley and western Nevada.
Due to the clear and dry conditions, temperatures were (on average) warmer than usual for January, but with a wide diurnal spread: overnight minimum temperatures were actually slightly *colder* than usual, but daytime high temperatures were significantly above average (and, thus, won out on in the monthly average).
In late January, the EMWD (Eastern Municipal Water District) was awarded nearly $4.5 million by the U.S. Army Corps of Engineers.
The funds will go towards the water district’s desalination infrastructure. Kevin Pearson is a spokesperson with the EMWD. “EMWD has a portion of its service area that has a salty groundwater basin, it’s naturally occurring, it has a higher salt contents than drinking water standards,” said Pearson.
Pearson says the water district uses reverse osmosis to purify the water and also discussed the award’s significance. The funds will go towards a study on future well sites and improvements to pipeline access.
State Assemblymember Eduardo Garcia, D-Coachella, Riverside County Supervisor V. Manuel Perez and other local leaders revealed a plan Saturday for a recreation and restoration project at the Salton Sea using $19.25 million in state funds.
The Salton Sea North Lake Pilot Demonstration Project is slated to be an approximately 156-acre marina that will be located near the current North Shore Beach and Yacht Club Community Center in the community of North Shore.
“The North Lake Pilot Demonstration Project is an important habitat and dust suppression project and a major investment in state funding to revitalize the northern end of the Salton Sea as well as the community of North Shore,” Perez said in a statement.
Hopes of a big drought busting year in California are starting to look grim after what felt like a great start to the rainy season.
January delivered little, if any, rain and snow and now February is off to an equally dry start. The winter whiplash continues to challenge water managers and with climate trends showing more of this boom or bust pattern, the state is rethinking its water supply system.
Now the state wants to head underground to explore what could be its biggest water storage potential.
The City of San Diego and the San Diego County Water Authority are planning to develop the San Vicente Energy Storage Facility Project.
The proposed hydro energy storage facility at the San Vicente Reservoir could generate enough energy for about 135,000 households.
How it works is the project would create a small upper reservoir above the existing, city-owned San Vicente reservoir. They’d be connected by a tunnel system and an underground powerhouse.
A mysterious lineage of the COVID-19 virus – containing a large and startling collection of mutations — has appeared in California’s wastewater system, proof that the fast-moving pathogen is continuing to test new survival strategies.
Oddly, the virus has been found only in poop, not people. First detected in an undisclosed community by UC Berkeley scientists, it has shown no signs of causing illness. It’s led to no new outbreaks.
So where is it coming from? And should we worry about it? No one knows for sure.
The construction of a proposed pumped hydro energy storage facility at the San Vicente Reservoir near Lakeside recently took a couple of steps forward but the project still needs to clear regulatory hurdles to become reality — and a backcountry conservation group has already come out in opposition to the project.
The city of San Diego and the San Diego County Water Authority have partnered on the San Vicente Energy Storage Facility Project, which looks to provide 500 megawatts and an estimated 4,000 megawatt-hours of long-duration stored energy to California’s electric grid. That’s enough to power about 135,000 households.
