I’ve been writing a lot about the broken sewage system in Tijuana causing spills into San Diego. Part of the concern, San Diego officials told me, is that Mexico lacks a system to monitor whether businesses are dumping toxic waste into the sewer system.
That’s part of the reason why it’s risky to reuse any of that river water because, if we don’t know what’s in the water, we can’t be sure how to best treat it.
San Diego County Water Authority Water Resources Manager Jeff Stephenson talks to ABC 10News about the area’s water supply following the release of the draft 2020 Urban Water Management Plan. The plan was released for public review March 8.
Every time someone turns on the tap in San Diego County, out flows the work of Peter MacLaggan.
MacLaggan was the point man in the construction of the Carlsbad desalination plant, a nearly $1 billion public-private partnership that since 2015 has supplied nearly 10 percent of the potable water consumed in the county.
Desalination relies on the virtually unlimited supply of water in the Pacific Ocean. It provides a safe, reliable source of local water in a region that for many years relied on supplies from hundreds of miles away and was subject to mechanical breakdowns, seasonal shortages and the whims of nature.
Since 1991, San Diego County ratepayers have conserved more than 1 million acre-feet of water, and per capita potable water use in the region decreased nearly 60 percent between fiscal years 1990 and 2019, according to the San Diego County Water Authority.
The findings are part of the Water Authority’s draft 2020 Urban Water Management Plan, which was released Monday for public review.
The report concludes that as a result of conservation and billions of dollars in infrastructure, San Diego should have sufficient water supplies through 2045.
“Thanks to decades of regional investments (and conservation) the draft plan shows that we don’t need to secure more regional supply sources for the foreseeable future,” Water Authority general manager Sandra Kerl said in a statement. “Instead we are focused on helping our member agencies develop local supplies, and looking for other ways we can continue to ensure supply reliability at a reasonable cost.”
A judge has ordered the Los Angeles Department of Water and Power to continue providing historic quantities of irrigation water to lessees of its pasturelands east of Yosemite, despite the agency’s assertion that climate change is making water resources in the Sierra Nevada watershed increasingly unreliable.
For decades, it was a source of drinking water for the San Marcos area. Today, the South Lake Reservoir has new life as a local wildlife habitat.
South Lake was built with an earthen dam and provided drinking water to the Lake San Marcos area, most of downtown San Marcos, and the Coronado Hills area. Updates to potable water treatment had detrimental effects on the lake ecology, so the Vallecitos Water District stopped using the lake as a drinking water source in 1984, although it remained an emergency water supply for another decade.
No matter whether their landscaping is just a few square feet alongside a front porch or estate acreage, thousands of San Diego County residents have learned to embrace sustainability as a central principle for creating and renovating their landscapes. The San Diego County Water Authority offers financial incentives and educational resources to customers in Fallbrook and Rainbow to improve their landscaping.
This year’s Women in Water Symposium conference theme “Flow With The Change” is fitting. Due to the coronavirus pandemic, the 2021 event is online with a new virtual format. The online format generated just as much enthusiasm from participants as prior in-person meetings. And, the virtual conference also meant people from throughout the United States could Zoom in too.
A late-winter storm doused the San Diego area with rain and mountain snow for second day Thursday, but a dry spell lies ahead.
Though the showers generated by the unsettled atmospheric system out of the Gulf of Alaska were more scattered and short-lived than Wednesday’s storms, they added to some significant moisture amounts across the county, according to the National Weather Service.
Today marks the anniversary of the deadliest man-made disaster in California history. It’s a largely forgotten event which killed hundreds of people in Ventura County. On March 12th, 1928, the St. Francis Dam collapsed, sending a wall of water more than 50 miles from the Santa Clarita area through the Santa Clara River Valley. More than 400 people died.
