There may be an average of 1,200 water main leaks a year with 200 of those considered major, but the last few weeks have proved that things seem to be worsening. And fast. A 12-inch pipe burst on Topanga Boulevard near Victory Boulevard in Canoga Park today, shutting down traffic on one of the West Valley's main north-south arteries, according to the LA Times. Of course, all these recent bursts causing traffic, damage and loss of service to customers has Los Angeles Department of Water & Power officials confused because as of right now, there is no apparent reason why this is happening so frequently and spread out. A slew of major incidents began when a trunkline in Studio City burst, causing a major flood followed by a rupture that caused a sinkhole that sucked in half a fire truck. Two breaks also occurred in the West Valley yesterday. Some officials say they have to raise our water bills to pay for replacing piping throughout the city.




I don't know if they're getting worse. You said it yourself - on average, there's a major water main break every 1.825 days. That's almost 4 a week. Perhaps the media is simply reporting them more often now after the Coldwater Canyon incident? The LADWP has a huge system of water mains to take care of.
Right now there is an uptick in the major blowout category. We're still on target for a leak of some kind, small or large, every 1.825 days ;)
Just wondering if all the water we have been conserving has caused some sort of pressure buildup in them old pipes?
.... causing the elderly pipes to just give out from all the added pressure?
We are now witness to the rise of the Teenage Mutant Ninja Turtles in Los Angeles. They won't stop breakin' water mains until they get their pizza, bro.
I was told this was happening because they received an anchovy pizza.
I just attended a talk on earthquake preparedness by one of Cal Tech's seismologists. Obviously, water is going to be a big issue when a major EQ strikes.
Referring to the recent breaks, she said that the infrastructure is over 100-year old and in desperate need of repair. When the Big One happens, forget about getting water for at least 2 weeks -- time for emergency relief to be able to kick in (got your EQ kit ready, everyone?)
She also said that to repair all the pipes in L.A. County would absorb more than one year of worldwide pipe production. I don't know where she got that stat from, but it certainly got the audience thinking.

Yes, yes, please store water in case of earthquakes!
