When it comes to slaking Southern California’s colossal thirst for water, more and more local governments are searching their own sewer lines for a solution.
In the face of dire drought, cities and water agencies are now investing heavily in large-scale wastewater recycling facilities — systems that will purify the billions of gallons of treated sewage that are currently flushed out to sea.
The view from high up in Del Mar’s 17th Street lifeguard station is a visit-California poster: a sweeping curve of sand, dramatic coastal bluffs, a welcoming sea. What scientists see, though, is somewhat more sobering: the Pacific Ocean as seething menace, a marine battering ram born of climate change that will inexorably claim more and more land and whatever sits upon it.
With rising seas now posing a greater threat to California’s economy than wildfires or severe earthquakes, state authorities are cautioning those who live along some of the Golden State’s famous beaches to do what they’re loath to do: retreat. Turn their backs to the sea and move homes, businesses, schools and critical infrastructure out of harm’s way.
The ocean could rise two to ten feet by 2100, imperiling $150 billion in property, according to state estimates, and erasing two-thirds of California’s beaches.
San Diego is experiencing considerably fewer breaks in water mains and sewer lines thanks to continuing replacement of deteriorating cast iron pipes, according to a year-end report released Wednesday.
A total of 38 water main breaks were reported in the city in 2019, a 38% reduction from the previous year. It was the lowest total in 15 years and far less than the peak of 131 breaks in 2010.
