I don;t think any major infrastructure upgrades have been made in this regard. Would like to hear that I am wrong about this.
Salty, I'm happy to say that the stormwater system is now totally separate from the sewer system.
They always were separate systems (or at least around 1980). The problem was that the storm system was inadequate and and the sewer system integrity was dicey so that it took on double its normal flow or more in storm events. And since so much of LA's precip is concentrated in a relatively few events, that represented a big proportion of total surface flow. Unless the stormwater system has been upgraded and the sewer system tightened up, I am guessing that not much has changed with respect to flows to Hyperion for example during storm events.
The questiion also remains what is being done with the stormwater that does manage to stay separate from the sewer: is any recovered?
