Sewer work begins

We came home last night to a very large dirt pile.

It's somewhere in the 8-10 foot range. Here are some children for scale.

As you can see, we also have our very own digger.

Right now, the work is on the neighbor's house and on the shared line between our houses. I think we got the dirt pile because they have more trees in their yard. Here is the trench leaving the neighbors' house, complete with busy workers, trying to get as much done as possible before the rain starts again. 

Here's the view between the houses, first from the backyard and then from the front.

Zooming in on the busted-up pieces of excavated pipe, they seem to be full of gravel.
