They construct a large hole using a track hoe with a hydraulic hammer.One was just installed a few block from me.It took 3 days of hammering from 7:00 AM to 7:00 PM.They then filled the leach pit with crushed stone and after it is inspected they will cover it with red cinders.
I could send you a picture if you like.
