My questions were mainly: If it's a major leak, you'd think it would get fixed relatively quickly, no? And secondly...where does the dirt go?

Just seems like that kind of massive cavern would take many years to make. And would be the result of an already-sketchy road (i.e. there was already a void beneath it).

1) They don't have a meter on a water main. If the reservoir is a lake, for example, a half inch of water missing could = millions of gallons.
The paving keeps it all together and the soil type "takes" the water so nobody knows. It was not a total break, so everybody was still getting water.
2) the upper layers of the earth's crust can be like swiss cheese. That water will take all the finer particles away, then build channels to keep taking it away to some void somewhere.

Soils get laid down containing leachable materials, like limestone and other dissolving things. It gets capped over and compacted (by glaciation, for example) and is quite strong.
millions of years of water flowing through it dissolves what it can, takes it away, and you have swiss cheese.

The reaction from the CSR when she calls her insurance company should be priceless.
