core drilling water basin for retention pond

Here we core drilled 2 two inch holes into the water basin of a retention pond off highway 49 in Harrisburg, NC. The area has seen much growth over the past 30 years and this particular job was to satisfy the Charlotte city engineers to make sure the pond drained correctly in case there cme one of those 100 year floods that happens every now and again. This is our basic wall core drilling rig where we use milwaukee core drill motors of different types to make holes in concrete walls and floor in North Carolina.
