AN AUTOMATIC RELIEF VALVE IS INSTALLED AT HIGH POINTS IN THE 12" NEW WATER PIPE. THE VALVE RELEASES AIR BUT NOT WATER. IT WORKS SIMILAR TO A WET VACUUM, WHERE A BALL FLOATS UP AND SHUTS OFF THE VALVE WHEN IT IS FULL OF WATER.
FIRST THE BRASS 12" SADDLE IS INSTALLED.. 
THEN THE SPECIAL DRILL BIT IS CONNECTED INTO THE SADDLE AND THE HOLE IS DRILLED OUT..
THEN THE BRASS PIPE IS THREADED IN..
THE HOLE IS FILLED WITH DIRT, THEN THE BASE OF THE A.R.V. IS PUT IN PLACE AND FILLED WITH GRAVEL..
THE LID IS SLIPPED ON AND SECURED...
AND IF YOU SEE ONE OF THESE IN YOUR YARD, YOU KNOW THAT IT IS KEEPING THE AIR OUT OF THE PIPE.
THE CONCRETE CREW IS POURING SAMAR AVE AND SAN JUAN AVE
