Pipes

There have been a number of incidents where water delivery systems in Los Angeles have burst, causing significant damage.

The Los Angeles Times notes that many area water pipes are old ("average age ... is 58 years" which probably means that half are before 1956) and that most of the leaking ones are from before 1950.

The tone of the article suggests that it is unlikely that anything will be done about it. The current plan, it notes, would not be able to complete repairs for 300 years. There is an an earlier note about how the Los Angeles river was set in concrete during the previous Fourth Turning, which might mean that people are willing to make investments in infrastructure when the need is definite and has been put off for too long.

And it does sound like we might be at that point, here.
