Sprinkler System Progress

It looks like a lot of lines got buried today.  There are also several sprinkler heads in the ground.  I think in total, there will be around 40 of them.  They're not all in yet, but it looks like most of them.  There are also some access points installed in the ground... maybe for draining during the winter?  My internet line also got buried for the 4th time today.  Hopefully that is the last time that has to be done.  Tomorrow they are going to install another water meter in the basement, the electronic controls, and tie into the house water supply.  On Friday the plumber will then connect the water from the house to the underground lines outside.
