Every time it rains, Angelenos might be thinking: are we saving any of that rain water?
Thursday’s storm brought some much needed rainfall, but with a burgeoning drought, many Southern California residents are wondering if we benefitted at all.
Extreme weather events in 2021 shattered records around the globe. Hundreds died in storms and heatwaves. Farmers struggled with drought, and in some cases with locust plagues. Wildfires set new records for carbon emissions, while swallowing forests, towns and homes.
Many of these events were exacerbated by climate change. Scientists say there are more to come – and worse – as the Earth’s atmosphere continues to warm through the next decade and beyond.
California will soak up some much needed rain this week on the heels of a sobering decision from the state to drastically reduce water distribution to the Los Angeles area due to our ongoing drought.
Meanwhile, the San Diego County Water Authority gets less than 1% of its water from the state, a remarkable difference from the 95% the agency received from the Metropolitan Water District of Southern California in the early 1990s. Conservation became a way of life in San Diego. Water use per day has been reduced by 50% since 1990 and remains consistent with levels seen during our last drought between 2012 and 2016.
"We ultimately were cut back by over 30% for 13 months. It harmed the economy and harmed the quality of life here. And it really wasn't a situation that we ever wanted to experience again," said Sandy Kerl, @sdcwa General Manager. #cawater #CAdrought https://t.co/NpJNAqDgN9

San Diego County Water Authority General Manager Sandra Kerl recently sat down with Brown and Caldwell’s Wendy Broley, director of technical practices, and Mike Puccio, Southern California operations director, to talk about her experience dealing with unprecedented challenges, including the COVID-19 pandemic, wildfires, and drought.
On the rare and welcome occasions when San Diego County gets rainfall, the water runoff from hard surfaces around the home such as roofs and patios should be re-directed to your permeable landscaping. By capturing as much rainwater as possible in the soil, it is possible to build an ecosystem that can last through the summer months with minimal additional irrigation.
Light to moderate precipitation in Southern California on Thursday may pave the way for a much stronger Pacific storm early next week, forecasters said.
Thursday’s drizzle is expected to deliver about a quarter-inch of rain to the Los Angeles area — only slightly more than the rainfall totals earlier this week — and taper off by the early evening.
The river that supplies water to about 40 million people is getting worryingly dry. Since the federal government officially declared a water shortage this summer, the Colorado River has been thrust into national headlines, and so have the scientists and decision makers who track and shape its future.
Four projects are being added to a waitlist as well. According to the EPA, as funds become available, $6.7 billion in WIFIA loans will help finance over $15 billion in water infrastructure projects to protect public health and water quality across 24 states.
“Far too many communities still face significant water challenges, making these transformative investments in water infrastructure so crucial,” said EPA Administrator Michael S. Regan in the EPA news release. “The WIFIA invited projects will deliver major benefits like the creation of good-paying jobs and the safeguarding of public health, especially in underserved and under-resourced communities. This program is a shining example of the public health and economic opportunities that will be achieved under President Biden’s Bipartisan Infrastructure Law.”
Extreme drought in California is forcing drastic measures on the 200,000 residents in Marin County. They have been told to cut their water usage to just 55 gallons a day.
A 10-minute shower uses about 25 gallons. A load of laundry uses 40 gallons of water. A single sprinkler head can spray out 15 gallons per minute.
The new restrictions mean no refilling swimming pools or fountains. Residents can’t wash their car in their driveways, and outdoor irrigation is prohibited.
By the end of December, the city will begin turning recycled water into drinkable water through its new, state-of-the-art water purification facility, the first of its kind in San Diego County.
The new water purification system, dubbed Pure Water Oceanside, uses ultrafiltration, reverse osmosis and an advanced oxidation process to purify recycled wastewater.
“It’s inspired by the natural water cycle and is the natural next step for recycling our precious water resource that we currently discharge into the ocean without tapping into its full potential,” said Oceanside Water Utilities Director Cari Dale, who has led the project.
