Water Explosion at the Swenson House

Tuesday as I drove onto our street at about 5pm, I saw that there were about 7 SF city vehicles of varying shapes and duties. The road was blocked off so I had to park on the other side of our block. Walking over to my house I saw our neighbor, Mary, watching the to-do. Come to find out, water had started to seep thru the tar that sealed the road to the cement of the gutter. Then there was this crazy explosion right in front of our house and water went everywhere. I hear it was a sight to see.
So our nice, new road was torn into and a 6 foot deep whole was dug to try and find the culprit pipe.
I thought you'd enjoy a low-quality video of the loud digging and rock-sucking action.

Here's the half-way point of the hole. This is the point that I arrived home. I do like how they cut such straight edges:
I think this picture shows the break in the tar and cement where the water had been seeping initially:
And here is the small piece of pipe that caused the whole ordeal:
The worker brought it over to show us. He thought it was pretty crazy.

No leaks inside and everything seems to back to normal. They patched up the hole in our road already on Wednesday so our nice street that they'd just fixed last summer is uneven right in front of our house :(
