Front Yard Geothermal: Digging

Trenching to the House

Monday, Halloween, was a busy day at our house. My daughter Antonia was sick, so I worked at home and got to see most of the action. It began the vacuuming of the slurry ponds and ended with the loop field connected into our basement.  (Click here for the previous week's work, drilling).

By the end of the day Wednesday the installation was complete.  Most of my pictures are from Monday though; the basement work on Tuesday and Wednesday was not nearly so dramatic.

To start with a picture from Monday morning would be in order.  This is how things stood after the drillers had finished up:

The areas enclosed by erosion fence are the slurry ponds. The stuff inside is goopy wet clay and rock that came out of the well holes. It looks a bit like a milkshake, but if you scoop down into it, it's heavy (like rock!)

The day began with a bit of snag.  Mark (Mark Doll, our contractor from Professional Geothermal) had talked to the excavator and decided the slurry ponds were not a big problem.  However when the excavator (Jim) arrived on site, they realized it was a problem.  So Mark found a company with a machine that "vacuums" up this stuff.  They then take it to a place where it is used in making something else (concrete? I forget now).  Here are some videos of that:

And in more detail:

It was very noisy!  However after an hour or two the slurry was gone.  Then it was time for the trenching:


By the end of the day Monday, things were back to a messy-but-stable state again, the trenches filled in, and things ready for the inside work.  I'll post pictures of that later.  For now, the thing to know is that by Wednesday night the inside work was done.  Since then, we have been off fossil fuels for our heating and hot water.  Our electric usage has increased dramatically (as expected).  It has varied with outside temperature, but it's around 18-30 kWh per day, where it had been 4 or 5.  But we have only used 0.1 therms of natural gas in 6 days (previously it was around 1.5 therms per day in this weather, and more than 0.1 therms per day in the summer just for the hot water).

This Friday the landscapers are supposed to come.  I'll do one last post about that.
